The frequency scores of infant macaques obtained during neurobehavioral assessment in the 1st month of life. Infants have been assigned to one of the two categories (imitators or nonimitators) according to their consistent imitative responses during the 1st week of life. Top and bottom graphs refer to the neurobehavioral scores obtained by infants categorized according to their neonatal imitative responses to tongue protrusion and lipsmacking gestures, respectively. Black dots indicate imitators and white dots indicate nonimitators.
