The stability of EEG was examined in infants of depressed (BDI > 16) a
nd non-depressed mothers (BDI < 9) from 3 months to 3 years. Of the 32
infants seen at 3 months, 15 were seen again at 3 years of age. Seven
of the eight children who had exhibited right frontal EEG asymmetry a
s infants still showed that EEG asymmetry pattern at the 3 year visit.
Children with right frontal EEG asymmetry at 3 years were observed to
be more inhibited during an exploratory play task, and children of de
pressed versus non-depressed mothers were less empathetic during simul
ated maternal distress.
