“…For instance, even though it is hard to determine to which degree defendants may intentionally feign amnesia following a crime, Pyszora et al (2003) found that 29% of a 1-year cohort of individuals sentenced to life imprisonment claimed memory loss for their deeds (31.4% of those convicted of homicide). While it might be that the intense emotional arousal that some perpetrators experience during the crime might impair memory (e.g., Kopelman, 1995 ), there is also the distinct possibility that perpetrators feign memory loss ( Centor, 1982 ; Marshall et al, 2005 ). Although majority of jurisdictions are reluctant to equate amnesia with incompetency, claiming crime-related amnesia in court raises the question whether the defendant’s ability to understand the trial proceedings or his capacity to consult with his attorney are impaired (e.g., Cima et al, 2002 ; Tysse, 2005 ; Tysse and Hafemeister, 2006 ).…”
