Peer reviewedContole, Julie; Over, Ray – Journal of Experimental Child Psychology, 1981
Six infants were filmed at 15 and 30 weeks of age while alone and in the presence of an adult (mother or stranger) who interacted with the infant or remained passive. Signal detection analysis of ratings made by judges showed that infant behavior at both ages varied in accord with whether or not an adult was present. (Author/DB)
