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 eit her high or low on both variables were observed at 14 months during a free-ploy period in an unfamiliar playroom. Five free-play variables w ere combined to produce a composite on which a high score was indicati ve of behavioral inhibition. The infants who had been high in motor ac tivity and crying at 4 months had higher inhibition scores than did th e infants with the opposite profile.
