Observations were made of the incidence of pointing behavior among infants differing in age when a radio-controlled truck entered the room in which mother and infant were seated. Infants' reactions over 5 to 6 minutes were recorded on videotape. Recordings were analyzed to establish the incidence of pointing, handedness of pointing, whether…

Tested 6 infants periodically until they were 28-weeks old for head and eye coordination in tracking moving targets and fixating stationary targets while subjects were moving. Found that head movement was more prevalent than eye movement. There was improvement with age in coordination of head turning to target or body movement. (BC)

Subjects were 16 infants with normal Apgar scores at birth who were volunteered by their parents after an initial contact in a maternity…

Four experiments investigating the effects of physical and social variables on the production of pointing in infants 10 to 18 months old are described. In the first two experiments, which were primarily concerned with the relation between reaching and index finger pointing, physical dimensions such as distance between baby and target objects were…
