Auditory evoked responses (AERs) were recorded from the frontal, temporal, and parietal scalp regions of nine male and nine female 16-month-old infants while they listened to a series of words. The brain responses reliably discriminated between words the infants were thought to understand versus those that they did not appear to know as judged by their parents and two independent raters. Findings from this study indicated that the brain wave patterns could discriminate known from unknown words. Sex differences in the patterns of lateralized hemispheric responses to the known and unknown words were also noted. These data indicate that auditory evoked responses may be used to detect differences in word meanings in young infants.
