Thurman, Sabrina L.; Corbetta, Daniela – Developmental Psychology, 2017
Infants' motor skill development triggers changes in parent-infant interactions, exploration, and play behaviors, particularly during periods of locomotor transitions. We investigated how these transitions reorganized infants' and mothers' explorations of spatial layouts. Thirteen infants and their mothers were followed biweekly from the age of 6…

This study examined the extent to which situational context differentially influences components of play. Two groups of play variables were distinguished: (1) style variables, (reflecting the overall tempo and diversity of play) and viewed as relatively sensitive indicators of short term reactions of situations; and (2) structural variables,…

Demographic data are included for the participating families, who are members of the Wolof in Senegal, Africa. For this study, interaction was defined as a sequence of behaviors involving both…

Weininger, O.; Moll, M. J. – 1977
This study was designed to identify aggressive actions in 12-, 18-, and 24-month-old infants and to investigate what type of responses these actions elicit in peers. Nine infants were observed and videotaped in interaction with each other and with toys. The focus was on four 18-month-olds observed in two sessions, one with an older child, the…

Contole, 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)

Dunn, Judy; Kendrick, Carol – Child Development, 1981
Individual differences in the social behavior of young siblings were studied in 40 sibling pairs observed at home, when the second child was 8 months old and 14 months old.

In the first experiment, the central issue investigated was whether facial configuration or height is utilized by infants to respond differentially to children and adults. Five different strangers, a male and a female child, a male and a female adult, and a small…
