Prior research suggests that infants' action production affects their action understanding, but little is known about the aspects of motor experience that render these effects. In Study 1, the relative contributions of self-produced (n = 30) and observational (n = 30) action experience on 3-month-old infants' action understanding was…

Infants of one, two and three months of age were presented with two checkerboard patterns, one stationary and the other moving in a horizontal oscillatory motion at one of eight rates. Results showed reliable differences in ocular behavior as a function of rate stimulus motion for all three groups of infants. (MS)

This study examines the influence of maternal predispositions toward sex-appropriate behavior and the mother's response to "feminine" or "masculine" cues in infant behavior. In the investigation, one 6-month-old male infant was presented to 11 mothers who served as subjects. The infant was dressed as either boy (blue clothes) and named Adam, or…

The purpose of the observational system presented here is to record the behavioral interactions between infant and mother, focusing on the sequential and contextual features of the social communication patterns accessible through direct home observation of mothers and their 3- to 4-month-old infants. The present system of continuous data recording…
