Fixation time, smiling, vocalization, and fret/cry were recorded to obtain a complete picture of infants' responses to facial stimuli over the first year of life. Four stimuli were presented to 120 infants. Results of fixation data indicate that (1) there is a marked decrease in fixation toward facial stimuli within the first year, (2) at all ages…

This study examines the relationship between mother-infant behavior and the infant's performance on perceptual-cognitive tasks as a function of the infant's sex.

This paper reports on a followup study of the long-term effects of infant care patterns among the Logoli people of East Africa. In the original study, 12 infants, ages 7-13 months, were observed to obtain a measure of the frequency with which the infant was held by the mother and others, latency of response to the infant's crying, and the number…

This study examines the degree to which young children are influenced by the familiarity of an adult participant in their pretend play with toys which vary in resemblance to highly prototypical objects (e.g., cup-like cups or doll-like dolls). A group of 29 children, mean age 21 months, was divided into two experimental groups balanced by sex; 15…
