Hypothesis
Atypical multisensory integration in individuals with ASD is secondary to attentional manipulation.
Conclusion
Individuals with ASD can process multisensory emotional stimuli, but their integration is differently modulated by attention mechanisms.
Supporting Evidence
- Individuals with ASD made significantly more errors with audiovisual stimuli than controls.
- Lower-order multisensory integration was intact in individuals with ASD.
- Attention manipulation affected the integration of visual and auditory emotional information.
Takeaway
This study shows that people with autism can understand emotions from both faces and voices, but they need to pay attention in a special way to do it well.
Methodology
Event-related potentials (ERPs) were measured in 23 high-functioning adult ASD individuals and 24 age- and IQ-matched controls while manipulating attention.
Potential Biases
Potential bias due to the selective attention conditions directed only to the visual modality.
Limitations
The study focused only on young adult males, which may limit the generalizability of the findings.
Participant Demographics
23 high-functioning adult males with ASD and 24 typically developing adult male controls.
