Bizarreness effect
Bizarreness effect is the tendency of bizarre material to be better remembered than common material.{{cite book |last1=Bäckman |first1=Lars |last2=Nyberg |first2=Lars |title=Memory, Aging and the Brain: A Festschrift in Honour of Lars-G ran Nilsson |date=24 August 2009 |publisher=Psychology Press |isbn=978-0-203-86666-5 |page=41 |url=https://books.google.com/books?id=0w1F7YlJ3RcC&pg=PA41}} However, scientific evidence for its existence is contested; some research suggests it does exist, some suggests it doesn't and some suggests it in fact worsens recollection.{{cite book |last=Schmidt |first=Stephen R. |title=Extraordinary Memories for Exceptional Events |date=4 May 2012 |publisher=Psychology Press |isbn=978-1-136-49936-4 |page=110 |url=https://books.google.com/books?id=OLHeZ9_K-SYC&pg=PA110}}
Causes
McDaniel and Einstein argue that bizarreness intrinsically does not enhance memory in their paper from 1986. They claim that bizarre information becomes distinctive. It is the distinctiveness that according to them makes encoding easier.{{cite journal |last1=Iaccino |first1=J. F. |last2=Sowa |first2=S.
