Gunnar, Megan R.; And Others – Child Development, 1984
Examines the effect of an unfamiliar peer in a situation requiring a subject's separation from mother in order to play with attractive toys. Observation of 20 children 18 months old and 20 children 30 months old revealed that peer presence facilitated initial separation for both ages, but that age differences in subsequent behaviors existed.
