Many criminal justice professionals perceive the eyewitness skills of individuals with intellectual disabilities to be weaker than those of typically developing (TD) individuals. Down syndrome (DS) is one of the most common genetic causes of intellectual disabilities, yet there is no research addressing eyewitness skills in this population. This study examined the eyewitness recall and suggestibility of young people with DS.
Young people with DS and mental age-matched TD children viewed a video of a non-violent petty crime and were subsequently asked to freely recall the event before being asked general and specific questions incorporating both misleading and non-leading prompts.
Compared with mental age-matched TD individuals, young people with DS produced as much information, were just as accurate and were no more suggestible.
The eyewitness memory skills of young people with DS are comparable to those of mental age-matched TD children. The implications of these findings for the forensic context and eyewitness memory are discussed.
许多刑事司法专业人员认为，智障人士的 eyewitness 技能比正常发育（TD）的人弱。唐氏综合征（DS）是智障最常见的遗传原因之一，但尚无针对该人群 eyewitness 技能的研究。本研究考察了患有 DS 的年轻人的 eyewitness 回忆和易受暗示性。
患有 DS 的年轻人和心理年龄匹配的 TD 儿童观看了一段非暴力轻微犯罪的视频，随后被要求自由回忆该事件，然后被问及包含误导性和非引导性提示的一般和具体问题。
与心理年龄匹配的 TD 个体相比，患有 DS 的年轻人提供的信息一样多，准确性相同，且同样不易受暗示。
患有 DS 的年轻人的 eyewitness 记忆技能与心理年龄匹配的 TD 儿童相当。讨论了这些发现对法医背景和 eyewitness 记忆的影响。
