dc.description.abstract
Successful social communication draws strongly on the correct interpretation
of others' body and vocal expressions. Both can provide emotional information
and often occur simultaneously. Yet their interplay has hardly been studied.
Using electroencephalography, we investigated the temporal development
underlying their neural interaction in auditory and visual perception. In
particular, we tested whether this interaction qualifies as true integration
following multisensory integration principles such as inverse effectiveness.
Emotional vocalizations were embedded in either low or high levels of noise
and presented with or without video clips of matching emotional body
expressions. In both, high and low noise conditions, a reduction in auditory
N100 amplitude was observed for audiovisual stimuli. However, only under high
noise, the N100 peaked earlier in the audiovisual than the auditory condition,
suggesting facilitatory effects as predicted by the inverse effectiveness
principle. Similarly, we observed earlier N100 peaks in response to emotional
compared to neutral audiovisual stimuli. This was not the case in the unimodal
auditory condition. Furthermore, suppression of beta–band oscillations (15–25
Hz) primarily reflecting biological motion perception was modulated 200–400 ms
after the vocalization. While larger differences in suppression between
audiovisual and audio stimuli in high compared to low noise levels were found
for emotional stimuli, no such difference was observed for neutral stimuli.
This observation is in accordance with the inverse effectiveness principle and
suggests a modulation of integration by emotional content. Overall, results
show that ecologically valid, complex stimuli such as joined body and vocal
expressions are effectively integrated very early in processing.
