Deficits in mental state attributions in individuals with 22q11.2 deletion syndrome (velo-cardio-facial syndrome).
People with 22q11.2 deletion syndrome show clear Theory-of-Mind gaps on lifelike video tasks, whether or not they also have autism.
01Research in Context
What this study did
The team showed short video clips to 46 people with 22q11.2 deletion syndrome (VCFS).
They also tested 25 typically-developing peers matched for age and IQ.
While watching each scene, participants rated whether the actor’s behavior was intentional and appropriate.
The clips were designed to trigger spontaneous mind-reading, not factual questions.
What they found
The VCFS group scored lower on both intentionality and appropriateness ratings.
The gap stayed even when people with VCFS also had autism; the syndrome itself drove the problem.
In plain words, they struggled to read everyday social cues that most of us catch automatically.
How this fits with other research
Carr (1994) saw the same pattern in able autistic adults using story tasks.
Both studies prove that passing classic false-belief tests does not guarantee real-life social insight.
Schuwerk et al. (2015) later echoed the result with eye-tracking in ASD, showing brief experience can help.
Whitehouse et al. (2014) extend the picture by finding spatial memory deficits in the same VCFS group, hinting at wider executive loads that may feed social slips.
Why it matters
If you work with VCFS clients, do not assume good eye contact equals intact perspective-taking.
Probe social understanding with dynamic, natural scenes instead of static questions.
Break social scripts into small steps and pre-teach the hidden intentions behind polite phrases.

03Original abstract
Velo-cardio-facial syndrome (VCFS; 22q11.2 deletion syndrome) results from a genetic mutation that increases risk for Autism Spectrum Disorder (ASD). We compared Theory of Mind (ToM) skills in 63 individuals with VCFS (25% with an ASD diagnosis) and 43 typically developing controls, and investigated the relationship of ToM to reciprocal social behavior. We administered a video-based task to assess mentalizing at two sites University of California, Los Angeles (UCLA) and State University of New York (SUNY) Upstate Medical University. The videos depicted interactions representing complex mental states (ToM condition), or simple movements (Random condition). Verbal descriptions of the videos were rated for Intentionality (i.e. mentalizing) and Appropriateness. Using Repeated Measures analysis of variance (ANOVA), we assessed the effects of VCFS and ASD on Intentionality and Appropriateness, and the relationship of mentalizing to Social Responsiveness Scale (SRS) scores. Results indicated that individuals with VCFS overall had lower Intentionality and Appropriateness scores than controls for ToM but not for Random scenes. In the SUNY sample, individuals with VCFS, both with and without ASD, performed more poorly than controls on the ToM condition; however, in the UCLA sample, only individuals with VCFS without ASD performed significantly worse than controls on the ToM condition. Controlling for site and age, performance on the ToM condition was significantly correlated with SRS scores. Individuals with VCFS, regardless of an ASD diagnosis, showed impairments in the spontaneous attribution of mental states to abstract visual stimuli, which may underlie real-life problems with social interactions. A better understanding of the social deficits in VCFS is essential for the development of targeted behavioral interventions.
