EEG reactions in emotional face recognition were studied in five participants with Asperger syndrome (AS) and seven control subjects. Control subjects showed a spectral power increase following the stimulus onset in two time-frequency intervals—(1) 150–300 ms in the 1–16 Hz frequency range and (2) 300–650 ms in the 1–8 Hz range. Also, alpha/beta desynchronization occurred 400–1000 ms after the stimulus onset with maximal amplitude in the posterior region. Theta synchronization (4–8 Hz) was weaker in the AS group than in the control group, but beta2 desynchronization was stronger in the AS group. The results were interpreted in terms of automatic and voluntary control of perception.
Research highlights
► Two moments of synchronization and alpha/beta desynchronization were obtained in control group.
► In AS group the theta synchronization was weakly than in control one.
► In AS group the beta2 desynchronization was stronger than in control one.
► The AS deficit in facial emotion recognition could be compensated by voluntary attention.
