An innovative collaboration between neuroscientists and developmental psychologists that investigated how infants’ brains process other people’s action provides evidence directly linking neural responses from the motor system to overt social behavior in infants.
The study involved thirty-six 7-month-old infants, who were each tested while wearing a cap that used electroencephalography (EEG) to measure brain activity. During the experiment, each infant observed an actor reach for one of two toys. Immediately after, the baby was allowed to select one of the same toys. This procedure was repeated 12 times.
