FREE-PLAY BEHAVIOR IN INHIBITED AND UNINHIBITED CHILDREN

Four-month-old infants were classified on motor activity and frequency of crying to visual and auditory stimuli. The subgroups that were either high or low on both variables were observed at 14 months during a free-ploy period in an unfamiliar playroom. Five free-play variables were combined to produce a composite on which a high score was indicative of behavioral inhibition. The infants who had been high in motor activity and crying at 4 months had higher inhibition scores than did the infants with the opposite profile.
