Applied behavior analysis#Fading

ABA is an applied science focused on developing procedures that will produce meaningful changes in behavior.{{cite book |last1=Cooper |first1=JO |last2=Heron |first2=TE |last3=Heward |first3=WL |title=Applied Behavior Analysis |year=2019 |publisher=Pearson Education (US) |isbn=978-0134752556 |page=19 |edition=3rd }} Behaviorists define behavior as any movement of some part of an organism that changes some aspect of the environment.{{cite book | vauthors = Johnston JM, Pennypacker HS |year=1993a |title=Strategies and tactics of behavioral research |location=Hillsdale, NJ |publisher=Erlbaum Associates |page=23 |isbn=978-0-8058-0905-3}}

In contrast, experimental analysis of behavior focuses on basic research in the field of behaviorism.{{cite journal | vauthors = Dillenburger K, Keenan M | title = None of the As in ABA stand for autism: dispelling the myths | journal = Journal of Intellectual & Developmental Disability | volume = 34 | issue = 2 | pages = 193–195 | date = June 2009 | pmid = 19404840 | doi = 10.1080/13668250902845244 | s2cid = 1818966 }} Both branches of behavior analysis adopt the viewpoint of radical behaviorism, treating thoughts, emotions, and other covert activity as behavior that is subject to the same responses as overt behavior.{{cite journal |last1=Baum |first1=WM |title=What is Radical Behaviorism? A Review of Jay Moore's Conceptual Foundations of Radical Behaviorism |journal=Journal of the Experimental Analysis of Behavior |date=2011 |volume=95 |issue=1 |pages=119–126 |doi=10.1901/jeab.2011.95-119|pmc=3014776 }} This represents a shift away from methodological behaviorism, which restricts behavior-change procedures to behaviors that are overt, and was the conceptual underpinning of behavior modification.

Behavior analysts emphasize that the science of behavior must be a natural science as opposed to a social science. As such, behavior analysts focus on the observable relationship of behavior with the environment, including antecedents and consequences, without resort to "hypothetical constructs".{{cite journal | doi=10.1037/h0054367 | title=Are theories of learning necessary? | date=1950 | last1=Skinner | first1=B.

The field of behaviorism originated in 1913 by John B. Watson with his seminal work "Psychology as the Behaviorist Views it."{{cite book |last1=Cooper |first1=JO |last2=Heron |first2=TE |last3=Heward |first3=WL |title=Applied Behavior Analysis |year=2019 |publisher=Pearson Education (US) |isbn=978-0134752556 |page=11 |edition=3rd }} In the article, Watson argued against the field of psychology's focus on consciousness and proposed that the field instead focus on observable behaviors, a concept referred to as methodological behaviorism.{{cite journal |last1=Watson |first1=JB |title=Psychology as the behaviorist views it. |journal=Psychological Review |date=1913 |volume=20 |issue=2 |pages=158–177 |doi=10.1037/h0074428|hdl=21.11116/0000-0001-9182-7 |hdl-access=free }}

In the 1930s, B. F. Skinner established the concept of radical behaviorism which extended Watson's theory to encompass private events that are unobservable to others, such as thoughts and sensations. {{cite journal |last1=Morris |first1=EK |last2=Altus |first2=DE |last3=Smith |first3=NG |title=A study in the founding of applied behavior analysis through its publications |journal=The Behavior Analyst |date=2013 |volume=35 |issue=1 |pages=73–107 |doi=10.1007/BF03392293 |pmid=25729133|pmc=3640891 }}

The initial experiments studying the effectiveness of behavior analysis on human subjects were published in the 1940s and '50s, including B.F. Skinner's "Baby in a box" in 1945 and Paul Fueller's "Operant conditioning of a vegetative human organism" (1949).

In 1957, the Society for Experimental Analysis of Behavior (SEAB) was founded by a group of behavioral psychologists, including Charles Ferster, to publish a journal that focused on operant conditioning, and the following year, the first edition of the Journal of the Experimental Analysis of Behavior was published. {{cite journal |last1=Laties |first1=Victor G. |title=THE JOURNAL OF THE EXPERIMENTAL ANALYSIS OF BEHAVIOR AT FIFTY |journal=Journal of the Experimental Analysis of Behavior |date=January 2008 |volume=89 |issue=1 |pages=95–109 |doi=10.1901/jeab.2008.89-95 |pmid=18338677 |pmc=2211445 }}

Teodoro Ayllon and Jack Michael's study "The psychiatric nurse as a behavioral engineer" in 1959 was the first to employ the seven dimensions of ABA, which demonstrated how effective a token economy was in altering the aberrant behavior of hospitalized patients with schizophrenia and intellectual disability.{{cite book |last1=Cooper |first1=JO |last2=Heron |first2=TE |last3=Heward |first3=WL |title=Applied Behavior Analysis |year=2019 |publisher=Pearson Education (US) |isbn=978-0134752556 |pages=11–14 |edition=3rd }}{{cite journal | vauthors = Ayllon T, Michael J | title = The psychiatric nurse as a behavioral engineer | journal = Journal of the Experimental Analysis of Behavior | volume = 2 | issue = 4 | pages = 323–334 | date = October 1959 | pmid = 13795356 | pmc = 1403907 | doi = 10.1901/jeab.1959.2-323 }}

The successful results from this study led researchers at the University of Kansas to start the Journal of Applied Behavior Analysis (JABA) in 1968.{{cite journal | vauthors = Eikeseth S, Smith T, Jahr E, Eldevik S | title = Outcome for children with autism who began intensive behavioral treatment between ages 4 and 7: a comparison controlled study | journal = Behavior Modification | volume = 31 | issue = 3 | pages = 264–278 | date = May 2007 | pmid = 17438342 | pmc = 3089401 | doi = 10.1007/BF03392239 }}

A group of researchers at the University of Washington, including Donald Baer, Sidney W. Bijou, Bill Hopkins, Jay Birnbrauer, Todd Risley, and Montrose Wolf,{{cite journal | vauthors = Lovitt TC | title = A brief history of applied behavior analysis at the University of Washington | journal = Journal of Applied Behavior Analysis | volume = 26 | issue = 4 | pages = 563–567 | date = 1993 | pmid = 16795814 | pmc = 1297893 | doi = 10.1901/jaba.1993.26-563 }}{{cite web|url=http://www.apbahome.net/resource/collection/1FDDBDD2-5CAF-4B2A-AB3F-DAE5E72111BF/APBAwhitepaperABAinterventions.pdf|title=Identifying applied behavior analysis interventions|work= Association of Professional Behavior Analysts |date=July 25, 2016|access-date=December 3, 2018}} applied the principles of behavior analysis to treat autism, manage the behavior of children and adolescents in juvenile detention centers, and organize employees who required proper structure and management in businesses. In 1968, Baer, Bijou, Risley, Birnbrauer, Wolf, and James Sherman joined the Department of Human Development and Family Life at the University of Kansas, where they founded the Journal of Applied Behavior Analysis.{{cite journal | vauthors = Baer DM | title = A brief, selective history of the Department of Human Development and Family Life at the University of Kansas: The early years | journal = Journal of Applied Behavior Analysis | volume = 26 | issue = 4 | pages = 569–572 | date = 1993 | pmid = 16795815 | pmc = 1297894 | doi = 10.1901/jaba.1993.26-569 }}

From 1960 through 1997, Ivar Lovaas researched the efficacy of ABA techniques on autistic children. While Lovaas is often considered a pioneer in the field of ABA{{Cite journal |last1=Smith |first1=Tristram |last2=Eikeseth |first2=Svein |date=March 2011 |title=O.

The practice has been condemned by the Association for Behavior Analysis International (ABAI).{{cite journal |last1=Larsson |first1=EV |last2=Wright |first2=S |title=O.

During the 1960s and 70s, researchers began experimenting on the use of ABA techniques in conversion therapy. These methodologies often involved the use of punishment procedures.{{cite journal |last1=Conine |first1=Daniel E. |last2=Campau |first2=Sarah C. |last3=Petronelli |first3=Abigail K. |title=LGBTQ + conversion therapy and applied behavior analysis: A call to action |journal=Journal of Applied Behavior Analysis |date=February 2022 |volume=55 |issue=1 |pages=6–18 |doi=10.1002/jaba.876|pmid=34407211 }} Lovaas and his doctoral student George Rekers published an article titled "Behavioral treatment of deviant sex-role behaviors in a male child" in 1974.{{cite journal |last1=Rekers |first1=George A. |last2=Lovaas |first2=O.

Despite the controversy, ABA continued to grow in the 1970s, and the first behavior analytic organizations outside of the United States and the United Kingdom were formed in Norway and Mexico.{{cite book |last1=Cooper |first1=John O. |last2=Heron |first2=Timothy E. |last3=Heward |first3=William L. |title=Applied behavior analysis |date=2019 |publisher=Pearson |location=Hoboken, New Jersey |isbn=978-0134752556 |page=8 |edition=Third}}

Over the years, "behavior analysis" gradually superseded "behavior modification"; that is, from simply trying to alter problematic behavior, behavior analysts sought to understand the function of that behavior, what reinforcement histories (i.e., attention seeking, escape, sensory stimulation, tangible access, etc.) promote and maintain it, and how it can be replaced by successful behavior.{{cite journal | vauthors = Mace FC, Critchfield TS | title = Translational research in behavior analysis: historical traditions and imperative for the future | journal = Journal of the Experimental Analysis of Behavior | volume = 93 | issue = 3 | pages = 293–312 | date = May 2010 | pmid = 21119847 | pmc = 2861871 | doi = 10.1901/jeab.2010.93-293 }}

Another resource for the characteristics of applied behavior analysis is the textbook Behavior Modification: Principles and Procedures.{{Cite book | vauthors = Miltenberger R, Virues-Ortega J |date=2020-05-01 |title=Modificación de conducta: Principios y Procedimientos | edition = 6th |doi=10.26741/2020/miltenberger6e|s2cid=218936697 }}

• Applied: ABA focuses on the social significance of the behavior studied and works to improve the lives of those receiving ABA services.
• Behavioral: ABA focuses on behavior, which is defined as the observable and measurable movements of an organism. Definitions of behavior should be written unambiguously so they can be clearly understood by a third party.
• Analytic: Behavior analysis is successful when the analyst understands and can manipulate the events that control a target behavior. This may be relatively easy to do in the lab, where a researcher is able to arrange the relevant events, but it is not always easy, or ethical, in an applied situation. In order to consider something to fall under the spectrum of analytic, it must demonstrate a functional relationship and it must be provable. Baer et al. outline two methods that may be used in applied settings to demonstrate control while maintaining ethical standards. These are the reversal design and the multiple baseline design. In the reversal design, the experimenter first measures the behavior of choice, introduces an intervention, and then measures the behavior again. Then, the intervention is removed, or reduced, and the behavior is measured yet again. The intervention is effective to the extent that the behavior changes and then changes back in response to these manipulations. The multiple baseline method may be used for behaviors that seem irreversible. Here, several behaviors are measured and then the intervention is applied to each in turn. The effectiveness of the intervention is revealed by changes in just the behavior to which the intervention is being applied.
• Technological: The description of analytic research must be clear and detailed so that any competent researcher can repeat it accurately.
• Conceptually Systematic: Behavior analysis should not simply produce a list of effective interventions; rather, intervention protocols should focus on including technological descriptions as well as theoretically meaningful terms, such as "secondary reinforcement" or "errorless discrimination", to help the reader understand how the concepts could be used in similar protocols.
• Effective: Interventions must produce behavioral changes that have a large enough effect to make meaningful, positive changes in the client's life.
• Generality: ABA intervention should focus on selecting and teaching new behaviors so the client can transfer those skills into new environments and stimuli outside of what was directly taught. Behavior analysts should incorporate plans for generalization when creating programs.

In 2005, Heward et al. suggested the addition of the following five characteristics:{{cite book | veditors = Heward WL, Heron TE, Neef NA, Peterson SM, Sainato DM, Cartlege GY, Cardner III R, Peterson LD, Hersch SB, Dardig JC |year=2005 |title=Focus on behavior analysis in education: Achievements, challenges, and opportunities |location=Upper Saddle River, NJ | publisher = Prentice Hall/Merrill |isbn=978-0-13-111339-8 }}

• Accountable: ABA must be able to demonstrate that its methods are effective. This requires repeatedly measuring the effect of interventions (success, failure or no effect at all), and, if necessary, making changes that improve their effectiveness.
• Public: The methods, results, and theoretical analyses of ABA must be published and open to scrutiny. There are no hidden treatments or mystical, metaphysical explanations.
• Doable: To be generally useful, interventions should be available to a variety of individuals, who might be teachers, parents, therapists, or even those who wish to modify their own behavior. With proper planning and training, many interventions can be applied by almost anyone willing to invest the effort.{{rp|205}}
• Empowering: ABA provides tools that give the practitioner feedback on the results of interventions. These allow clinicians to assess their skill level and build confidence in their effectiveness.{{harvnb|Cooper|Heron|Heward|1987|p=19}}
• Optimistic: Behavior analysts have cause to be optimistic that their efforts are socially worthwhile, for the following reasons:
• The behaviors impacted by behavior analysis are largely determined by learning and controlled by manipulable aspects of the environment.
• Practitioners can improve performance by direct and continuous measurements.
• As a practitioner uses behavioral techniques with positive outcomes, they become more confident of future success.
• The literature provides many examples of success in teaching individuals considered previously unteachable.

Although there are many applications of ABA outside of autism intervention, a large majority of ABA practitioners specialize in autism, and ABA itself is often mistakenly considered synonymous with therapy for autism.{{Cite web |title=BACB CERTIFICANT DATA |url=https://www.bacb.com/bacb-certificant-data/ |access-date=2022-05-14 |website=Behavior Analyst Certification Board |language=en-US}} Practitioners often use ABA-based techniques to teach adaptive behaviors to, or diminish challenging behaviors presented by, individuals with autism.{{cite journal | vauthors = Matson JL, Hattier MA, Belva B |title=Treating adaptive living skills of persons with autism using applied behavior analysis: A review |journal=Research in Autism Spectrum Disorders |date=January–March 2012 |volume=6 |issue=1 |pages=271–276 |doi=10.1016/j.rasd.2011.05.008 }}{{cite journal | vauthors = Myers SM, Johnson CP | title = Management of children with autism spectrum disorders | journal = Pediatrics | volume = 120 | issue = 5 | pages = 1162–1182 | date = November 2007 | pmid = 17967921 | doi = 10.1542/peds.2007-2362 | doi-access = free }} ABA methodologies such as differential reinforcement, extinction, and task analysis, are among the most well-researched evidence-based practices for autism intervention.{{cite journal | vauthors = Wong C, Odom S, Hume K, Cox A, Fettig A, Kucharczyk S, Schultz T | title = Evidence-based practices for children, youth, and young adults with autism spectrum disorder: A comprehensive review. | journal = Journal of Autism and Developmental Disorders | volume = 45 | issue = 7 | pages = 1951–1966| date = 2015 | doi = 10.1007/s10803-014-2351-z | pmid = 25578338 }} In North America, ABA therapy is primarily provided by behavior technicians who deliver direct intervention under the supervision of Board Certified Behavior Analysts (BCBAs), who conduct assessments and write treatment plans for clients.{{Cite book |last=Luiselli |first=James K. |title=Applied Behavior Analysis Advanced Guidebook: A Manual for Professional Practice |date=2023 |publisher=Elsevier Science & Technology |isbn=978-0-323-99595-5 |edition=2nd |location=San Diego |pages=138}}

In 1987, Lovaas published the study, "Behavioral treatment and normal educational and intellectual functioning in young autistic children". The experimental group in this study received an average of 40 hours per week in a 1:1 teaching setting at a table using errorless DTT with a trained therapist.{{cite journal | vauthors = Lovaas OI | title = Behavioral treatment and normal educational and intellectual functioning in young autistic children | journal = Journal of Consulting and Clinical Psychology | volume = 55 | issue = 1 | pages = 3–9 | date = February 1987 | pmid = 3571656 | doi = 10.1037/0022-006x.55.1.3 }} The treatment was implemented in the childs' home. A heavy emphasis was placed on teaching eye contact, fine and gross motor imitation, academics, receptive and expressive language, and oral motor imitation. Each new skill is taught through prompting, modeling, and shaping. The outcome of this study indicated 47% of the experimental group (9/19) went on to lose their autism diagnosis and were described as indistinguishable from their typically developing adolescent peers. This included passing general education without assistance and forming and maintaining friendships. These gains were maintained as reported in the 1993 study, "Long-term outcome for children with autism who received early intensive behavioral treatment". Lovaas' work was recognized by the US Surgeon General and New York State Department of Health in 1999, and his research was replicated in university and private settings.{{cite journal | vauthors = Sallows GO, Graupner TD | title = Intensive behavioral treatment for children with autism: four-year outcome and predictors | journal = American Journal of Mental Retardation | volume = 110 | issue = 6 | pages = 417–438 | date = November 2005 | pmid = 16212446 | doi = 10.1352/0895-8017(2005)110[417:IBTFCW]2.0.CO;2 | s2cid = 12305283 }}{{cite journal | vauthors = Cohen H, Amerine-Dickens M, Smith T | title = Early intensive behavioral treatment: replication of the UCLA model in a community setting | journal = Journal of Developmental and Behavioral Pediatrics | volume = 27 | issue = 2 Suppl | pages = S145–S155 | date = April 2006 | pmid = 16685181 | doi = 10.1097/00004703-200604002-00013 | s2cid = 15927226 }} The "Lovaas Method" went on to become known as early intensive behavioral intervention (EIBI).

In 2018, a Cochrane meta-analysis database concluded that preliminary research suggests that there are two different ABA teaching approaches to gaining spoken language: children with higher receptive language skills respond to 2.5 – 20 hours per week of the naturalistic approach, whereas children with lower receptive language skills acquire words from 25 hours per week of discrete trial training—the structured and intensive form of ABA.{{cite journal | vauthors = Brignell A, Chenausky KV, Song H, Zhu J, Suo C, Morgan AT | title = Communication interventions for autism spectrum disorder in minimally verbal children | journal = The Cochrane Database of Systematic Reviews | volume = 2018 | issue = 11 | pages = CD012324 | date = November 2018 | pmid = 30395694 | pmc = 6516977 | doi = 10.1002/14651858.CD012324.pub2 }} A 2023 multi-site randomized control trial study of 164 participants showed similar findings.{{cite journal | vauthors = Kasari C, Shire S, Shih W, Landa R, Levato L, Smith T | title = Spoken language outcomes in limited language preschoolers with autism and global developmental delay: RCT of early intervention approaches | journal = Autism Research | volume = 16 | issue = 6 | pages = 1236–1246 | date = June 2023 | pmid = 37070270 | pmc = 10460274 | doi = 10.1002/aur.2932 }}

{{Main|Operant conditioning}}

Operant behavior is voluntary behavior that is sensitive to, or controlled by, its consequences. Specifically, operant conditioning refers to the three-term contingency that uses stimulus control. In the three-term contingency, a discriminative stimulus (sD) first signals to the subject that reinforcement (or, less commonly, punishment) is available. Then, the subject performs a behavior. After performing a behavior, a consequence will occur that either adds (positive) or removes (negative) something that will make the behavior either occur more (reinforcement) or less (punishment) frequently in the future.{{cite journal |last1=Leeder |first1=Thomas M. |title=Behaviorism, Skinner, and Operant Conditioning: Considerations for Sport Coaching Practice |journal=Strategies |date=4 May 2022 |volume=35 |issue=3 |pages=27–32 |doi=10.1080/08924562.2022.2052776 }}

{{Main|Reinforcement}}

Reinforcement occurs when the consequence of a behavior makes it more likely for that behavior to occur in the future. Reinforcing consequences can be either positive, where something preferred is added, or negative, where something aversive is removed.{{cite book |last1=Cooper |first1=JO |last2=Heron |first2=TE |last3=Heward |first3=WL |title=Applied Behavior Analysis |year=2019 |publisher=Pearson Education (US) |isbn=978-0134752556 |page=36 |edition=3rd }} Reinforcement is the key element in operant conditioning and most behavior change programs.{{cite book | vauthors = Flora SR |title=The Power of Reinforcement |date=2004 |publisher=SUNY Press |isbn=978-0-7914-5916-4 }}{{page needed|date=June 2024}}{{cite journal | vauthors = Northup J, Vollmer TR, Serrett K | title = Publication trends in 25 years of the Journal of Applied Behavior Analysis | journal = Journal of Applied Behavior Analysis | volume = 26 | issue = 4 | pages = 527–537 | year = 1993 | pmid = 16795803 | pmc = 1297882 | doi = 10.1901/jaba.1993.26-527 }} There are multiple schedules of reinforcement that affect the future probability of behavior.

{{Main|Punishment (psychology)}}

Punishment occurs when the consequences of a behavior make the behavior less likely to occur in the future.{{Cite journal | publisher = OpenStax | journal = Lumen Learning |title=Reinforcement and Punishment |url=https://pressbooks.online.ucf.edu/lumenpsychology/chapter/operant-conditioning/ |language=en | vauthors = Learning L }} As with reinforcement, a stimulus can be added (positive punishment) or removed (negative punishment). Broadly, there are three types of punishment: presentation of aversive stimuli (e.g., pain), response cost (removal of desirable stimuli such as monetary fines), and restriction of freedom (as in a 'time out').{{harvnb|Cooper|Heron|Heward|1987|p=355}} Punishment in practice can often result in unwanted side effects, such as an increase in aggressive behaviors.{{cite book |last1=Cooper |first1=John O. |title=Applied behavior analysis |last2=Heron |first2=Timothy E. |last3=Heward |first3=William L. |date=2019 |publisher=Pearson |isbn=978-0134752556 |edition=Third |location=Hoboken, New Jersey |page=336}} Some other potential unwanted effects include resentment over being punished, attempts to escape the punishment, expression of pain and negative emotions associated with it, and recognition by the punished individual between the punishment and the person delivering it. Because of the risks and ethical considerations associated with punishment procedures, the Behavior Analysts Certification Board's code of ethics prohibits behavior analysts from utilizing punishment procedures unless less intrusive methods have been unsuccessful or "the risk of harm to the client outweighs the risk

associated with the behavior-change intervention."{{cite web |title=Ethics code for behavior analysts |url=https://bacb.com/wp-content/ethics-code-for-behavior-analysts/ |publisher=Behavior Analyst Certification Board. |access-date=10 May 2025}}

{{Main|Classical conditioning}}

Respondent (classical) conditioning is based on involuntary reflexes. In respondent conditioning, an unconditioned response occurs in the presence of an unconditioned stimulus. When a neutral stimulus is repeatedly paired with an unconditioned stimulus, the response will begin occurring in the presence of the previously neutral stimulus; thus, the neutral stimulus and the unconditioned response become a conditioned stimulus and conditioned response, respectively.{{cite journal |last1=Rehman |first1=Ibraheem |last2=Mahabadi |first2=Navid |last3=Sanvictores |first3=Terrence |last4=Rehman |first4=Chaudhry I. |title=Classical Conditioning |url=https://pubmed.ncbi.nlm.nih.gov/29262194/ |website=StatPearls |publisher=StatPearls Publishing |access-date=10 May 2025 |date=2025|pmid=29262194 }} In his experiments with dogs, Ivan Pavlov presented dogs with food (unconditioned stimulus) and observed that the dogs began salivating (unconditioned response). Before running the experiment, the dogs did not salivate when Pavlov rang a bell (neutral stimulus). During the experiment, Pavlov rang a bell whenever he presented the dogs with food. After pairing the bell with the food, Pavlov stopped presenting the food with the bell, but the dogs continued to salivate when hearing the bell alone; thus, the bell became the conditioned stimulus, and salivating at the sound of the bell became a conditioned response. Unlike operant conditioning, the response does not produce a reinforcer or punisher (e.g., the dog does not get food because it salivates) in respondent conditioning.

{{Main|Extinction (psychology)}}

Extinction is the technical term to describe the procedure of withholding/discontinuing reinforcement of a previously reinforced behavior, resulting in the decrease of that behavior.{{cite book | vauthors = Miltenberger RG | title = Behavior modification: Principles and procedures. | publisher = Thomson/Wadsworth | date = 2008 | edition = 4th | isbn = 978-0-495-09153-0 }}{{rp|102}} The behavior is then set to be extinguished (Cooper et al.). Extinction procedures are often preferred over punishment procedures, as many punishment procedures are deemed unethical and in many states prohibited. Nonetheless, extinction procedures must be implemented with utmost care by professionals, as they are generally associated with extinction bursts. An extinction burst is the temporary increase in the frequency, intensity, and/or duration of the behavior targeted for extinction.{{rp|104}} Other characteristics of an extinction burst include an extinction-produced aggression—the occurrence of an emotional response to an extinction procedure often manifested as aggression; and b) extinction-induced response variability—the occurrence of novel behaviors that did not typically occur prior to the extinction procedure. These novel behaviors are a core component of shaping procedures.

In addition to a relation being made between behavior and its consequences, operant conditioning also establishes relations between antecedent conditions and behaviors. This differs from the S–R formulations (If-A-then-B), and replaces it with an AB-because-of-C formulation. In other words, the relation between a behavior (B) and its context (A) is because of consequences (C), more specifically, this relationship between AB because of C indicates that the relationship is established by prior consequences that have occurred in similar contexts.{{cite journal | vauthors = Moxley RA |year=2004 |title=Pragmatic selectionism. The philosophy of behavior analysis |journal=The Behavior Analyst Today |volume=5 |pages=108–25 |doi=10.1037/h0100137}} This antecedent–behavior–consequence contingency is termed the three-term contingency. A behavior which occurs more frequently in the presence of an antecedent condition than in its absence is called a discriminated operant. The antecedent stimulus is called a discriminative stimulus (S^D). The fact that the discriminated operant occurs only in the presence of the discriminative stimulus is an illustration of stimulus control.{{harvnb|Cooper|Heron|Heward|1987|p=41}} More recently behavior analysts have been focusing on conditions that occur prior to the circumstances for the current behavior of concern that increased the likelihood of the behavior occurring or not occurring. These conditions have been referred to variously as "Setting Event", "Establishing Operations", and "Motivating Operations" by various researchers in their publications.

{{Main|Verbal Behavior}}

B. F. Skinner's classification system of human language in behavior analysis has been applied to treatment of a host of communication disorders.{{cite journal | vauthors = Peterson P | date = 2007 | title = Promoting generalization and maintenance of skills learned via natural language teaching. | journal = The Journal of Speech and Language Pathology – Applied Behavior Analysis | volume = 4 | issue = 1 | pages = 90–131 | doi = 10.1037/h0100252 }} Skinner's system includes:

• Tact – a verbal response evoked by a non-verbal antecedent and maintained by generalized conditioned reinforcement (e.g., identifying items, people, or nonhuman animals).
• Mand – behavior under control of motivating operations maintained by a characteristic reinforcer (e.g., direct reinforcement for a self-initiated request).
• Intraverbals – verbal behavior for which the relevant antecedent stimulus was other verbal behavior, but which does not share the response topography of that prior verbal stimulus (e.g., responding to another speaker's question).
• Echoic – vocal imitation under control of verbal stimuli (e.g., repeating what is said).
• Autoclitic – secondary verbal behavior which alters the effect of primary verbal behavior on the listener. Examples involve quantification, grammar, and qualifying statements (e.g., the differential effects of "I think..." vs. "I know...")

In behavior analysis, behavior is defined as any movement of an organism that changes the environment; thus, behavior includes both voluntary (operant) and involuntary (respondent) behavior. Ogden Lindsley developed the Dead Man's Test to assist behaviorists in differentiating between behaviors and passive states of being. In it, the behaviorist must determine if the target is something a dead person could do; if it is, the target is not a behavior.{{cite journal |last1=Critchfield |first1=Thomas S. |last2=Shue |first2=Elva Z. H. |title=The Dead Man Test: a Preliminary Experimental Analysis |journal=Behavior Analysis in Practice |date=31 December 2018 |volume=11 |issue=4 |pages=381–384 |doi=10.1007/s40617-018-0239-7 |pmid=30538911 |pmc=6269387 }} According to Johnston and Pennypacker, behavior has three dimensions that can be measured: repeatability, temporal extent, and temporal locus.{{cite book | vauthors = Johnston JM, Pennypacker HA |title=Readings for Strategies and tactics of behavioral research |year=1993 |edition=2nd |location=Hillsdale, HF |publisher=Erlbaum |isbn=978-0-8058-0906-0}}

Response classes occur repeatedly throughout time—i.e., how many times the behavior occurs.

• Count is the number of occurrences in behavior.
• Rate/frequency is the number of instances of behavior per unit of time.
• Celeration is the measure of how the rate changes over time.

The temporal extent refers to the duration of the response, which is the measure of time from the start to the end of the response. The duration of a response is either the duration of each response or the duration of all responses during a specific timeframe, which is then recorded as a percentage.{{Cite book |title=Applied Behavior Analysis |vauthors= Cooper JO, Heron TE |publisher=Pearson Education |year=2019 |isbn=978-0134752556 |edition=3rd |page=78 }}

Latency specifically measures the time that elapses between the event of a stimulus and the behavior that follows. This is important in behavioral research because it quantifies how quickly an individual may respond to external stimuli, providing insights into their perceptual and cognitive processing rates.{{cite book | vauthors = Dowdy A, Nepo K, Miodus S, Quigley S, Sevon M | chapter = Operational Definitions, Observation, and Behavioral Recording in Applied Behavior Analysis |date=2023 | title = Handbook of Applied Behavior Analysis for Children with Autism: Clinical Guide to Assessment and Treatment | series = Autism and Child Psychopathology Series |pages=107–129 | veditors = Matson JL |place=Cham |publisher=Springer International Publishing |language=en |doi=10.1007/978-3-031-27587-6_6 |isbn=978-3-031-27587-6 }} There are two measurements that are able to define temporal locus, they are response latency and interresponse time.

• Response latency measures the time between the presentation of a stimulus, such as an instruction, and the first response.{{cite journal |last1=Thomason-Sassi |first1=Jessica L. |last2=Iwata |first2=Brian A. |last3=Neidert |first3=Pamela L. |last4=Roscoe |first4=Eileen M. |title=Response Latency As An Index Of Response Strength During Functional Analyses Of Problem Behavior |journal=Journal of Applied Behavior Analysis |date=March 2011 |volume=44 |issue=1 |pages=51–67 |doi=10.1901/jaba.2011.44-51 |pmid=21541141 |pmc=3050468 }}
• Interresponse time refers to the duration of time that occurs between two instances of behavior, and it helps in understanding patterns and frequency of a certain behavior on a period of time.

Derivative measures are additional metrics derived from primary data, often by combining or transforming dimensional quantities to offer deeper insights into a phenomenon. Despite not being directly tied to specific dimensions, these measures provide valuable supplemental information. In applied behavior analysis (ABA), for example, percentage is a derivative measure that quantifies the ratio of specific responses to total responses, offering a nuanced understanding of behavior and assisting in evaluating progress and [https://iris.peabody.vanderbilt.edu/module/fba/cresource/q4/p12/ intervention effectiveness].

Trials-to-criterion, another ABA derivative measure, tracks the number of response opportunities needed to achieve a set level of performance.

{{Further|Discrete trial training}}

In 1965, early development of discrete trial training (DTT) techniques, which was also known as the Lovaas method, involved the use of electric shocks, scolding, and the withholding of food.{{Cite journal| vauthors = Kirkham P |date=2017-04-01|title='The line between intervention and abuse' – autism and applied behaviour analysis|journal=History of the Human Sciences |volume=30|issue=2|pages=107–126|doi=10.1177/0952695117702571|s2cid=152017417 }}{{cite journal|url=https://pediatrics.aappublications.org/content/133/3/364|vauthors=Bowman RA, Baker JP|title=Screams, slaps, and love: The strange birth of applied behavior analysis|journal=Pediatrics|volume=133|issue=3|pages=364–66|date=March 2014|doi=10.1542/peds.2013-2583|pmid=24534411|s2cid=28137037|url-access=subscription}} Ivar Lovaas published a series of articles that described a pioneering investigation of the antecedents and consequences that maintained a problem behavior,{{cite journal | vauthors = Smith T, Eikeseth S | title = O.

{{Main|Chaining}}

Chaining is the process of teaching the steps of a task analysis. The two methods of chaining, forward chaining and backward chaining, differ based on what step a learner is taught to complete first. In forward chaining, the ABA practitioner teaches the learner to independently complete the first step and prompts the learner for all subsequent steps. In backward chaining, the practitioner prompts all steps except the last step. As the learner begins to respond independently, the practitioner systematically removes the prompts and teaches the next step in the task analysis.

Total task presentation is a variation of forward chaining where the practitioner asks the learner to perform the entire task analysis and provides prompting only when the learner is unable to complete a step independently.{{cite book |last1=Cooper |first1=JO |last2=Heron |first2=TE |last3=Heward |first3=WL |title=Applied Behavior Analysis |year=2019 |publisher=Pearson Education (US) |isbn=978-0134752556 |pages=563–569 |edition=3rd }}

A prompt is a cue that encourages a desired response from an individual.{{cite book |author=Ontario Ministry of Education |year=2007 |title=Effective Educational Practices for Students with ASD |publisher=Queen's Printer for Ontario}} Prompts fall into one of two categories: stimulus prompts and response prompts. Stimulus prompts alter the environment in a way that makes the correct response more salient. Different types of stimulus prompts include positional, redundancy, and gestural prompts. Response prompts are cues directed toward the learner that include verbal, model, and physical prompts.{{cite book |last1=Cooper |first1=John O. |last2=Heron |first2=Timothy E. |last3=Heward |first3=William L. |title=Applied behavior analysis |date=2020 |publisher=Pearson |location=Hoboken, NJ |isbn=978-0134752556 |page=404 |edition=Third}} Prompts are often categorized into a prompt hierarchy from most intrusive to least intrusive, although there is some controversy about what is considered most intrusive, those that are physically intrusive or those that are hardest prompt to fade (e.g., verbal).{{cite journal | vauthors = Barnett D, Bauer A, Bell S, Elliott N, Haski H, Barkley E, Baker D, Mackiewicz K |year=2006 |title=Preschool Intervention Scripts: Lessons from 20 years of Research and Practice |journal=Journal of Speech-Language Pathology and Applied Behavior Analysis |volume=2 |issue=2 |pages=158–81 |doi=10.1037/h0100216 }} When using a most-to-least prompting strategy, the instrutor begins prompting the learner using the most intrusive prompt in the heiarchy and systematically fading the prompts after multiple correct responses.{{cite journal | vauthors = Chesnut M, Williamson PN, Morrow JE |year=2003 |title=The use of visual cues to teach receptive skills to children with severe auditory discrimination deficits |journal=Behav Analyst Today |volume=4 |issue=2 |pages=212–24 |doi=10.1037/h0100120}} In contrast, when using a least-to-most prompting strategy, the instructor will first prompt the learner using the least intrusive prompt. If the learner does not respond correctly, the instructor will gradually increase the intrusiveness of the prompt until the learner emits a correct response.{{cite journal |last1=Libby |first1=Myrna E. |last2=Weiss |first2=Julie S. |last3=Bancroft |first3=Stacie |last4=Ahearn |first4=William H. |title=A Comparison of Most-to-Least and Least-to-Most Prompting on the Acquisition of Solitary Play Skills |journal=Behavior Analysis in Practice |date=June 2008 |volume=1 |issue=1 |pages=37–43 |doi=10.1007/BF03391719|pmid=22477678 |pmc=2846579 }}

Other prompting strategies include no-no and errorless (or simultaneous) prompting. Errorless prompting involves providing a prompt that will result in a correct response immediately after presenting the instruction in order to minimize errors. Alternatively, when utilizing a no-no prompt, the learner is given an errorless prompt only after they have emitted two incorrect responses. {{cite journal |last1=Leaf |first1=Justin B. |last2=Sheldon |first2=Jan B. |last3=Sherman |first3=James A. |title=Comparison of Simultaneous Prompting and No-No Prompting in Two-Choice Discrimination Learning with Children with Autism |journal=Journal of Applied Behavior Analysis |date=June 2010 |volume=43 |issue=2 |pages=215–228 |doi=10.1901/jaba.2010.43-215|pmid=21119896 |pmc=2884346 }}

The overall goal is for an individual to eventually not need prompts. As an individual gains mastery of a skill at a particular prompt level, the prompt is faded to a less intrusive prompt. This ensures that the individual does not become overly dependent on a particular prompt when learning a new behavior or skill.

One of the primary choices that was made while showing another way of behaving is the manner by which to fade the prompts or prompts. An arrangement should be set up to fade the prompts in an organized style. For instance, blurring the actual brief of directing a kid's hands might follow this succession: (a) supporting wrists, (b) contacting hands softly, (c) contacting lower arm or elbow, and (d) pulling out actual contact through and through. Fading guarantees that the kid does not turn out to be excessively subject to a specific brief while mastering another expertise.{{cite web | vauthors = Prince K | work = Behavioral Consulting of Tampa Bay, Inc. | title = The importance of measuring behavior | date = 13 March 2013 | url = https://bcotb.com/the-importance-of-measuring-behavior/ | access-date = 3 July 2022 | archive-date = 9 February 2023 | archive-url = https://web.archive.org/web/20230209115907/https://bcotb.com/the-importance-of-measuring-behavior/ | url-status = dead }}

According to behaviorists, all behavior has at least one of the four following functions: sensory, access, escape, or attention. Functional behavioral assessment (FBA) is the process of analyzing data on a targeted behavior to determine which function is reinforcing the target behavior. FBAs that rely on directly observing and measuring the behavior (as opposed to indirect measures, like parent interviews) are also called descriptive behavior assessments.{{cite book |last1=Cooper |first1=John O. |title=Applied behavior analysis |last2=Heron |first2=Timothy E. |last3=Heward |first3=William L. |date=2019 |publisher=Pearson |isbn=0134752554 |edition=Third |location=Hoboken, New Jersey |page= |pages=630 - 631}}

Functional analysis is a process of experimentally controlling the environment in order to determine the function of a target behavior.{{cite journal |last1=Iwata |first1=Brian A. |last2=Dorsey |first2=Michael F. |last3=Slifer |first3=Keith J. |last4=Bauman |first4=Kenneth E. |last5=Richman |first5=Gina S. |title=TOWARD A FUNCTIONAL ANALYSIS OF SELF‐INJURY |journal=Journal of Applied Behavior Analysis |date=June 1994 |volume=27 |issue=2 |pages=197–209 |doi=10.1901/jaba.1994.27-197|pmc=1297798 }}

Thinning is often confused with fading. Fading refers to a prompt being removed, where thinning refers to an increase in the time or number of responses required between reinforcements.{{cite journal | vauthors = LeBlanc LA, Hagoplan LP, Maglieri KA, Poling A |year=2002 |title=Decreasing the intensity of reinforcement-based interventions for reducing behavior: conceptual issues and a proposed model for clinical practice |journal=Behav Analyst Today |volume=3 |issue=3 |pages=289–300 |doi=10.1037/h0099991}} Periodic thinning that produces a 30% decrease in reinforcement has been suggested as an efficient way to thin.{{cite journal | vauthors = Cautilli J |year=2005 |title=Brief report: application of proposed model of decreasing reinforcement intensity |journal=Int J Behav Consult Ther |volume=1 |issue=1 |pages=21–36 |doi=10.1037/h0100731}} Schedule thinning is often an important and neglected issue in contingency management and token economy systems, especially when these are developed by unqualified practitioners (see professional practice of behavior analysis).{{cite book |doi=10.4324/9781315669212 |title=Ethics for Behavior Analysts |date=2016 | vauthors = Bailey J, Burch M |isbn=978-1-317-36344-6 }}

Pivotal response treatment (PRT) is a naturalistic ABA-based intervention which targets skills that, when mastered, "can elicit more widespread positive clinical gains in the child’s other domains of functioning."{{cite journal |last1=Lei |first1=Jiedi |last2=Ventola |first2=Pamela |title=Pivotal response treatment for autism spectrum disorder: current perspectives |journal=Neuropsychiatric Disease and Treatment |date=June 2017 |volume=13 |pages=1613–1626 |doi=10.2147/NDT.S120710|doi-access=free |pmid=28790824 |pmc=5488784 }} PRT's primary focus is increasing the learner's motivation by self-initiated requesting and to engage them socially through play within a behavioral framework. PRT recognizes that learners may be unmotivated to communicate due to natural causes, like genetic influences, and how learned helplessness from previously unsuccessful communication attempts can discourage future communication attempts.{{cite book |last1=Koegel |first1=Robert L. |last2=Koegel |first2=Lynn Kern |title=Pivotal response treatment for autism spectrum disorders |date=2019 |publisher=Paul H. Brookes Publishing Co |location=Baltimore |isbn=9781681252988 |edition=Second |url=https://brookespublishing.com/wp-content/uploads/2021/07/Koegel-PRT-pocket-guide-intro.pdf |access-date=29 November 2024}}

Generalization is the expansion of a student's performance ability beyond the initial conditions set for acquisition of a skill.{{cite book | vauthors = Alberto P, Troutman AC |title=Applied Behavior Analysis for Teachers |date=2006 |publisher=Pearson Merrill Prentice Hall |isbn=978-0-13-117994-3 }}{{page needed|date=June 2024}} Generalization can occur across people, places, and materials used for teaching. For example, once a skill is learned in one setting, with a particular instructor, and with specific materials, the skill is taught in more general settings with more variation from the initial acquisition phase. For example, if a student has successfully mastered learning colors at the table, the teacher may take the student around the house or school and generalize the skill in these more natural environments with other materials. Behavior analysts have spent a considerable amount of time studying factors that lead to generalization.{{cite journal | vauthors = Osnes PG, Lieblein T |year=2003 |title=An explicit technology of generalization |journal=Behav Analyst Today |volume=3 |issue=4 |pages=364–74 |doi=10.1037/h0099994}}

{{Main|Shaping (psychology)}}

Shaping involves modifying a single existing behavior into the target behavior by differentially reinforcing successive approximations of the target behavior. When the learner emits a response that is closer to the target behavior than previous responses, the new response is reinforced, and any instances of the old response are no longer reinforced. For example, if the target behavior were for the learner to say the word bubbles, a practitioner may initially blow bubbles in response to every vocal utterance made by the learner. Once the learner started emitting a bu- sound, the practitioner would only blow bubbles when the learner made this response. Eventually, the practitioner would only blow bubbles when the learner said bubbles.{{Cite web | vauthors = Gilmore H | title = Shaping, Chaining, & Task Analysis with an Example from Everyday Life |date=20 February 2020 | url = https://psychcentral.com/pro/child-therapist/2020/02/shaping-chaining-task-analysis-with-an-example-from-everyday-life }}

Acceptance and commitment therapy (ACT) is a clinical approach based on behavior analytic principles and guided by the theoretical framework of relational frame theory.{{cite journal |last1=Hayes |first1=Steven C. |last2=Pierson |first2=Heather |title=Acceptance and Commitment Therapy |journal=Encyclopedia of Cognitive Behavior Therapy |year=2005 |pages=1–2 |doi=10.1007/0-306-48581-8_1 |isbn=0-306-48580-X }} The primary goal of ACT is to help the client acknowledge negative or unwanted private events, such as thoughts and feelings, and shift their self-identity from one based on psychological phenomenon to one based in self-as-context. Among the techniques the therapy uses include mindfulness and shaping. It is typically employed as a psychotherapeutic procedure or for athletic training purposes.{{cite journal |last1=Kelly |first1=Amanda D. |last2=Kelly |first2=Michelle E. |title=Acceptance and Commitment Training in Applied Behavior Analysis: Where Have You Been All My Life? |journal=Behavior Analysis in Practice |date=March 2022 |volume=15 |issue=1 |pages=43–54 |doi=10.1007/s40617-021-00587-3|pmid=34341679 |pmc=8320414 }}

Many neurodiversity advocates, including autistic people who have experienced ABA interventions, criticize that ABA attempts to eliminate, suppress or reduce autistic behaviors and reinforces autistic people to mask their true characteristics, imitate non-autistic behaviors (e.g. eye contact, body language) and conform to an overly narrow conception of normal behavior.{{cite web|url=http://nymag.com/news/features/47225/index4.html|title=The Autism Rights Movement| vauthors = Soloman A |website=New York Magazine|date=23 May 2008 |access-date=8 March 2016}}{{Cite web | vauthors = Cernius Y | date = 13 May 2022 |title=Commentary: The autistic community is having a reckoning with ABA therapy.

A 2020 study examined perspectives of autistic adults that received ABA as children and found that the overwhelming majority reported that "behaviorist methods create painful lived experiences," that ABA led to the "erosion of the true actualizing self," and that they felt they had a "lack of self-agency within interpersonal experiences." Another study published in 2023 in Autism found similar results, with evidence of increased masking and causing mental health challenges for some autistic people.{{cite journal | url=https://journals.sagepub.com/doi/full/10.1177/13623613221118216 | doi=10.1177/13623613221118216 | title=Autistic experiences of applied behavior analysis | date=2023 | journal=Autism | volume=27 | issue=3 | pages=737–750 | pmid=35999706 | vauthors = Anderson LK }}

Conflicts of interest, methodological concerns, and a high risk of bias pervade most ABA studies.{{cite journal | vauthors = Bottema-Beutel K, Crowley S | title = Pervasive Undisclosed Conflicts of Interest in Applied Behavior Analysis Autism Literature | journal = Frontiers in Psychology | volume = 12 | pages = 676303 | date = 2021 | pmid = 34025538 | pmc = 8131529 | doi = 10.3389/fpsyg.2021.676303 | doi-access = free }}{{cite journal | vauthors = Reichow B, Hume K, Barton EE, Boyd BA | title = Early intensive behavioral intervention (EIBI) for young children with autism spectrum disorders (ASD) | journal = The Cochrane Database of Systematic Reviews | volume = 5 | issue = 5 | pages = CD009260 | date = May 2018 | pmid = 29742275 | pmc = 6494600 | doi = 10.1002/14651858.CD009260.pub3 }}{{Cite web |date=2011-09-28 |title=How we made the decision {{!}} Evidence {{!}} Autism spectrum disorder in under 19s: recognition, referral and diagnosis {{!}} Guidance {{!}} NICE |url=https://www.nice.org.uk/guidance/cg128/resources/surveillance-report-2016-autism-spectrum-disorder-in-under-19s-recognition-referral-and-diagnosis-2011-nice-guideline-cg128-and-autism-spectrum-disorder-in-under-19s-support-and-management-2013-nice--2660567437/chapter/How-we-made-the-decision?tab=evidence |access-date=2025-06-04 |website=www.nice.org.uk |quote=...high quality evidence was not found for ABA during guideline development or surveillance review.

One study revealed extensive undisclosed conflicts of interest (COI) in published ABA studies. 84% of studies published in top behavioral journals over a period of one year had at least one author with a COI involving their employment, either as an ABA clinical provider or a training consultant to ABA clinical providers. However, only 2% of these studies disclosed the COI.

Low-quality evidence is likewise a concern in some research reporting on the potential harms of ABA on autistic children.{{cite book |doi=10.1002/9781119679028.ch39 |chapter=Helping Autistic Children |title=The Wiley-Blackwell Handbook of Childhood Social Development |date=2022 | vauthors = Davis R, Den Houting J, Nordahl-Hansen A, Fletcher-Watson S |pages=729–746 |isbn=978-1-119-67898-4 |url=https://osf.io/zrfyp/ }}

Another concern is that ABA research only measures cognition or behavior as a means of success, which has led to a lack of qualitative research about autistic experiences of ABA, a lack of research examining the internal effects (e.g. mental health, well being, emotions) of ABA and a lack of research for autistic children who are non-speaking or have co-occurring intellectual disabilities.{{Cite journal |vauthors=McGill O, Robinson A |date=October 2020 |title='Recalling hidden harms': autistic experiences of childhood applied behavioural analysis (ABA) |url=https://strathprints.strath.ac.uk/73753/1/McGill_Robinson_AA_2020_autistic_experiences_of_childhood_Applied_Behavioural_Analysis.pdf |journal=Advances in Autism |language=en |volume=7 |issue=4 |pages=269–282 |doi=10.1108/AIA-04-2020-0025 |s2cid=225282499}}{{Cite journal |vauthors=Sandoval-Norton AH, Shkedy G, Shkedy D |date=June 2021 |title=Long-term ABA Therapy Is Abusive: A Response to Gorycki, Ruppel, and Zane |journal=Advances in Neurodevelopmental Disorders |language=en |volume=5 |issue=2 |pages=126–134 |doi=10.1007/s41252-021-00201-1 |s2cid=234848417 |doi-access=free}}{{cite journal | vauthors = Shreck KA, Metz B, Mulick JA, Smith A |year=2000 |title=Making it fit: A Provocative Look at Models of Early Intensive Behavioral Intervention for Children with Autism |journal=The Behavior Analyst Today |volume=1 |issue=3 |pages=27–32|doi=10.1037/h0099886 }}{{cite journal | vauthors = Weiss MJ, Delmolino L |year=2006 |title=The Relationship Between Early Learning Rates and Treatment Outcome For Children With Autism Receiving Intensive Home-Based Applied Behavior Analysis |journal=The Behavior Analyst Today |volume=7 |issue=1 |pages=96–105 |doi=10.1037/h0100140}} Research is also lacking about whether ABA is effective long-term and very little longitudinal outcomes have been studied.

Opponents of ABA have denounced the ABA ethical code as too lenient, citing its failure to restrict or clarify the use of aversives, the absence of an autism or child development education requirement for ABA therapists, and its emphasis on parental consent rather than the consent of the person receiving services.{{cite journal | vauthors = Wilkenfeld DA, McCarthy AM | title = Ethical Concerns with Applied Behavior Analysis for Autism Spectrum "Disorder" | journal = Kennedy Institute of Ethics Journal | volume = 30 | issue = 1 | pages = 31–69 | date = 2020 | pmid = 32336692 | doi = 10.1353/ken.2020.0000 | s2cid = 216557299 }} Numerous researchers have argued that some forms of ABA interventions can be abusive and can increase symptoms of post-traumatic stress disorder (PTSD) in people undergoing the intervention.{{Cite journal |vauthors=Kupferstein H |date=2018-01-02 |title=Evidence of increased PTSD symptoms in autistics exposed to applied behavior analysis |journal=Advances in Autism |language=en |volume=4 |issue=1 |pages=19–29 |doi=10.1108/AIA-08-2017-0016 |s2cid=4638346}}{{Cite journal |vauthors=Sandoval-Norton AH, Shkedy G, Shkedy D |date=2019-01-01 |title=How much compliance is too much compliance: Is long-term ABA therapy abuse? |journal=Cogent Psychology |volume=6 |issue=1 |pages=1641258 |doi=10.1080/23311908.2019.1641258 |s2cid=199041640 |doi-access=free |veditors=Rushby JA}} Some bioethicists argue that employing ABA violates the principles of justice and nonmaleficence and infringes on the autonomy of both autistic children and their parents.

Lovaas incorporated aversives into some of the ABA practices he developed, including employing electric shocks, slapping, and shouting to modify undesirable behavior. Although the use of aversives in ABA became less common over time, and in 2012 their use was described as inconsistent with contemporary practice,{{cite book |doi=10.1017/CBO9780511978616.011 |chapter=Behavioral treatments for children with ASDs |title=The Autism Spectrum |date=2012 | vauthors = Spreat S |pages=239–257 |isbn=978-0-521-11687-9 }} aversives persisted in some ABA programs. In comments made in 2014 to the US Food and Drug Administration (FDA), a clinician previously employed by the Judge Rotenberg Educational Center claimed that "all textbooks used for thorough training of applied behavior analysts include an overview of the principles of punishment, including the use of electrical stimulation."{{cite report |url=http://www.fda.gov/downloads/AdvisoryCommittees/CommitteesMeetingMaterials/MedicalDevices/MedicalDevicesAdvisoryCommittee/NeurologicalDevicesPanel/UCM395024.pdf |title=Aversive comments – part 1 |date=14 April 2014 |publisher=United States Food and Drug Administration |page=4 |docket=FDA-2014-N-0238 |access-date=10 October 2020 |archive-url=https://wayback.archive-it.org/7993/20170114045650/http://www.fda.gov/downloads/AdvisoryCommittees/CommitteesMeetingMaterials/MedicalDevices/MedicalDevicesAdvisoryCommittee/NeurologicalDevicesPanel/UCM395024.pdf |archive-date=2017-01-14 |url-status=dead |vauthors=Cameron M}}
