Dissimulation Of Mental Retardation And Traumatic Brain Injury On The Wais -Ii, Joshua E Caron Jan 2006

Dissimulation Of Mental Retardation And Traumatic Brain Injury On The Wais -Ii, Joshua E Caron

UNLV Retrospective Theses & Dissertations

Since Atkins v. Virginia (2002), there has been increased concern that inmates will feign mental retardation (MR) to avoid the death penalty. However, very little research on malingering diction for mental retardation has been conducted, forcing most clinicians to rely on methods derived for malingered traumatic brain injury (TBI). This lack of research may lead to increased false positive rates. Limited research suggests that intelligence tests may hold promise for identifying malingered MR and malingered TBI. Therefore, developing malingering scales for most popular measure of intelligence, the WAIS-III, should provide the most effective and efficient measure for identifying persons feigning …
