虽然患有威廉姆斯综合征（WS）的个体具有移情和社交能力，并且在面部识别任务中表现相对较好，但他们在面部表情识别任务中表现不佳。目前的研究试图调查这种看似不一致的情况。参与者进行了测试的加纳型匹配的范例中，身份和表达被操纵同时作为相关或不相关的尺寸。WS的人在表达匹配任务上的表现很差，主要依赖于一致的身份所提供的便利。身份匹配任务的性能接近匹配控制的性能水平，并显着促进一致的表达。我们讨论了潜在的帐户的差异处理的表达式在任务相关（公开）和任务无关（隐蔽）的条件下，扩大公开表达匹配的内在语义概念的性质和它的依赖一般认知水平。
Although individuals with Williams Syndrome (WS) are empathic and sociable and perform relatively well on face recognition tasks, they perform poorly on tasks of facial expression recognition. The current study sought to investigate this seeming inconsistency. Participants were tested on a Garner-type matching paradigm in which identities and expressions were manipulated simultaneously as the relevant or irrelevant dimensions. Performance of people with WS on the expression-matching task was poor and relied primarily on facilitation afforded by congruent identities. Performance on the identity matching task came close to the level of performance of matched controls and was significantly facilitated by congruent expressions. We discuss potential accounts for the discrepant processing of expressions in the task-relevant (overt) and task-irrelevant (covert) conditions, expanding on the inherently semantic-conceptual nature of overt expression matching and its dependence on general cognitive level.
