| Description: |
Humans rapidly and spontaneously activate muscles in the face when viewing emotional facial expressions in others. These rapid facial reactions (RFRs) are thought to reflect low-level, bottom-up processes, and are theorized to assist an observer to experience and share the affect of another individual. It has been assumed that RFRs are present from birth; however to date, no study has investigated this response in children younger than 3 years of age. In the present study, we used facial electromyography (EMG) to measure corrugator supercilii (brow) and zygomaticus major (cheek) muscle activity in 7-month-old infants while they viewed happy and angry facial expressions. The results showed that 7-month olds exhibited greater zygomaticus activity in response to happy expressions than angry expressions, however, we found no evidence of differential corrugator muscle activity. |
