Investigating basic emotion knowledge of people with Williams syndrome

Area of Science:

• Neuroscience
• Developmental Psychology
• Cognitive Science

Background:

• Emotional recognition is crucial for understanding others' minds.
• Williams syndrome (WS) is associated with hypersocial and empathetic traits.
• Limited research exists on emotion processing in individuals with WS.

Purpose of the Study:

• To investigate emotion knowledge in people with Williams syndrome.
• To understand emotion-related mentalizing abilities in WS.
• To compare emotion processing across different developmental and clinical groups.

Main Methods:

• Tested recognition of six basic emotions (happiness, sadness, anger, fear, disgust, surprise) using narrated scenarios.
• Participants with WS listened to scenarios and identified emotions via emoticons.
• Compared WS group (n=16) with mental age-matched controls (n=16), chronological age-matched controls (n=16), sixth graders (n=20), and college students (n=20).

Main Results:

• Individuals with WS demonstrated delayed emotion processing compared to mental age-matched controls.
• WS group's emotion processing differed from chronological age-matched controls.
• Developmental differences observed between sixth graders and college students, indicating prolonged emotion processing maturation.

Conclusions:

• A significant gap exists in emotion knowledge maturation for individuals with WS compared to typically developing peers.
• Emotion-related mentalizing ability in WS is not equivalent to chronological age expectations.
• Emotion processing undergoes developmental changes from childhood through adulthood.
