Disturbance of face memories in a case with Williams syndrome

Abstract

  Williams syndrome (WS) is a neurodevelopmental disorder caused by a hemizygous deletion in chromo some 7. Individuals with WS generally show a socio-cognitive trait known as “hypersociability”, and are relatively preserved in perceiving facial stimuli. However, little is known about long-term memory for faces and its disturbance in WS. In the present study, we investigated short-term memories (STM) and long-term memories (LTM) for faces in a case with WS. In the STM tasks for faces, a case of WS showed higher scores than participants with intellectual disabilities
