Computerized False Belief Tasks Impact Mentalizing Ability in People with Williams Syndrome

Area of Science:

• Neurodevelopmental Disorders
• Cognitive Psychology
• Developmental Psychology

Background:

• Williams syndrome (WS) is associated with distinct social and cognitive profiles, including hyper-sociability and advanced face processing.
• Previous assessments of mentalizing abilities in WS using 2D stimuli yielded inconsistent results.
• The efficacy of computerized social cognition tools for WS remains underexplored.

Purpose of the Study:

• To investigate the impact of structured computerized animations on the mentalizing abilities of individuals with Williams syndrome.
• To determine if these animations can improve false belief understanding in the WS population.
• To compare the performance of individuals with WS to typically developing controls on computerized false belief tasks.

Main Methods:

• Participants with WS and typically developing controls viewed computerized animations depicting false belief scenarios (unexpected location and content changes).
• Post-animation assessments included questions on character identification, reality, memory, and false belief comprehension.
• Responses were systematically recorded and analyzed to evaluate mentalizing skills.

Main Results:

• Individuals with WS demonstrated enhanced false belief comprehension from structured animations, achieving this skill at a younger chronological age (5.9 years) than previously reported.
• This finding contrasts with prior studies indicating later acquisition or persistent deficits in theory of mind for WS.
• Despite improvements, individuals with WS still showed a lower developmental level in false belief processing compared to typically developing peers.

Conclusions:

• Structured computerized animations can significantly enhance mentalizing abilities and theory of mind in individuals with Williams syndrome.
• The findings suggest a potential for developing effective computerized social skills interventions tailored for WS.
• Early intervention using these tools may improve social cognition outcomes for individuals with WS.
