Executive function refers to the interrelated top down cognitive processes that are integral in the management of actions, thoughts, and emotions (Diamond2013)

Williams syndrome (WS) is a genetic disorder caused by a hemideletion of 26 28 genes on chromosome 7q11.23.

Individuals with WS often have mild to moderate intellectual disability, as well as impairments in executive function. The greatest executive function difficulty for individuals with WS is inhibitory control ( Mervis & Greiner de Magalhães , in press).

We directly evaluated inhibitory control using a laboratory measure of delay of gratification in 6 8 year olds with WS. The purpose of the current study was to describe and characterize the performance of children with WS on a delay of gratification task. Furthermore, we evaluated the relations among child performance on the inhibitory control measure, child intellectual ability, and parent report of executive function.
