Attention to faces in Williams syndrome

Area of Science:

• Neurodevelopmental disorders
• Cognitive psychology
• Social neuroscience

Background:

• Williams syndrome (WS) is characterized by unique social behaviors, including prolonged face fixation.
• This social phenotype often co-occurs with attention difficulties.
• Attention's multifaceted nature may influence gaze behavior in individuals with WS.

Purpose of the Study:

• To investigate attention to faces in Williams syndrome.
• To examine attention capture, interference, bias, and disengagement from faces in WS.
• To compare attention patterns in WS with typically developing individuals.

Main Methods:

• Four experiments were conducted to assess different aspects of attention to faces.
• Participants included individuals with WS and typically developing controls matched for nonverbal ability and age.
• Measures included attention capture, interference, face bias, and attention disengagement.

Main Results:

• No atypicalities in attention capture by faces, interference from facial stimuli, or face bias were found in WS.
• A notable finding suggested individuals with WS experienced significantly more difficulty disengaging attention from faces compared to objects.
• This contrasts with typical attention patterns observed in control participants.

Conclusions:

• The findings suggest that attention abnormalities in Williams syndrome may stem from difficulties in disengaging attention from faces.
• Prolonged face fixation in WS could be linked to impaired attention disengagement mechanisms.
• Further research is needed to fully understand the face disengagement difficulties in WS and their impact on social behavior.
