| Abstract | Two studies used event-related potentials (ERPs) to examine neural manifestations of emotion recognition in 7-month-old infants. In the first study, 20 infants were presented with 2 alternating achromatic slides of the same female model posing a happy and a fearful expression. Infants' ERPs revealed a prominent positive component to the happy face and baseline activity to the fearful face. In the second study, infants were first presented with flashes of alternating pictures of two different models posing happy faces or fearful faces. A series of test trials followed, 25 percent of which contained 1 of the models seen previously, posing the previously seen, or familiar, expression; another 25 percent contained a previously unseen model posing the familiar expression; the remaining 50 percent portrayed a previously seen or unseen model portraying the previously unseen, or novel, expression (fear, if familiarized to happy; happy, if familiarized to fear). Analysis revealed that infants familiarized to happy evinced positive waveform activity to the happy expression and baseline activity to the fearful expression. In contrast, infants familiarized to fear showed effectively identical responses to both expressions. Results from both studies suggest that during familiarization infants struggle with both identity and expression information, resulting in none of the stimuli being exhaustively processed. Six figures showing ERP responses are included. (MM) |
