Abstract |
Audiovisual speech perception was studied in adults with Asperger syndrome (AS), by utilizing the McGurk effect, in which conflicting visual articulation alters the perception of heard speech. The AS group perceived the audiovisual stimuli differently from age, sex and IQ matched controls. When a voice saying /p/ was presented with a face articulating /k/, the controls predominantly heard /k/. Instead, the AS group heard /k/ and /t/ with almost equal frequency, but with large differences between individuals. There were no differences in gaze direction or unisensory perception between the AS and control participants that could have contributed to the audiovisual differences. We suggest an explanation in terms of weak support from the motor system for audiovisual speech perception in AS. |
