Abstract EN
This study focused on auditory emotional perception in children with low-functioning autism and investigated the children’s response to emotionally charged nonverbal sounds which regularly induced emotional response in typically developing (TD) peers.
An EEG was conducted, and emotional reactions were assessed using analog scales and images of presented sounds with additional images during the presentation of emotional stimuli.
The results showed that EEG and emotional responses to the fearful sounds were similar in TD children and children with autism spectrum disorders (ASD).
Both groups of children showed an increase in peak alpha frequency and power of alpha2-band and a decrease in low-frequency bands.
Sounds of crying and laughter induced an atypical EEG response in children with ASD, with no change in alpha-band’s power and frequency observed in them; this was contrary to the observation in TD children.
The decrease in the fractal dimension detected in children with ASD only for sounds of crying and laughter correlated with the accuracy of assessment of these stimuli.
