The Implicit Relational Assessment Procedure (IRAP) is a computer-based psychological measure. It was heavily influenced by the implicit-association test,{{Cite journal |last1=Barnes-Holmes |first1=Dermot |last2=Barnes-Holmes |first2=Yvonne |last3=Stewart |first3=Ian |last4=Boles |first4=Shawn |date=2010 |title=A sketch of the Implicit Relational Assessment Procedure (IRAP) and the Relational Elaboration and Coherence (REC) model |url=http://eprints.maynoothuniversity.ie/4952/1/YBH_sketch.pdf |journal=The Psychological Record |volume=60 |issue=3 |pages=527–542 |doi=10.1007/BF03395726|s2cid=55621415 }} and is one of several tasks referred to as indirect measures of implicit attitudes.{{Cite journal |last1=Nosek |first1=Brian A. |last2=Hawkins |first2=Carlee Beth |last3=Frazier |first3=Rebecca S. |year=2011 |title=Implicit social cognition: from measures to mechanisms |journal=Trends in Cognitive Sciences |volume=15 |issue=4 |pages=152–159 |doi=10.1016/j.tics.2011.01.005 |pmc=3073696 |pmid=21376657}}{{Cite book |last1=De Houwer |first1=Jan |title=Handbook of implicit social cognition: measurement, theory, and applications |last2=Moors |first2=Agnes |date=2010 |publisher=Guilford Press |isbn=9781606236734 |editor-last=Gawronski |editor-first=Bertram |editor-link=Bertram Gawronski |location=New York |pages=176–195 |chapter=Implicit measures: similarities and differences |oclc=457010488 |editor-last2=Payne |editor-first2=B.

Application and use
= Procedure =
A computer-based measure, the IRAP requires individuals to accurately and quickly respond to the relation between two stimuli presented on screen (e.g., to "dog" and "woof") using one of two response options (e.g., "similar" and "different"). Across pairs of blocks, individuals must respond using two contrasting response patterns, for example "dog-woof-similar" versus "dog-woof-different". Reaction times are then compared between these blocks. Any difference in response time between the two block types is defined as an IRAP effect. According to the creators, "the basic hypothesis is that average response latencies should be shorter across blocks of consistent relative to inconsistent trials. In other words, participants should respond more rapidly to relational tasks that reflect their current beliefs than to tasks that do not".
= Implementations =
The IRAP was first implemented in Visual Basic 6, and distributed for free for academic use but under a closed source by Dermot Barnes-Holmes. A multi-platform, open-source implementation written in PsychoPy is also available on the Open Science Framework.{{Cite journal |last=Hussey |first=Ian |year=2016 |title=OSF {{!}} Open Source Implicit Relational Assessment Procedure |url=https://osf.io/kg2q8/ |doi=10.17605/osf.io/kg2q8}}
