Infants watched an experimenter retrieve a stuffed animal from an opaque box and then return it. This happened twice, consistent with either 1 animal appearing on 2 occasions or 2 identical-looking animals each appearing once. The experimenter labeled each object appearance with a different novel label. After infants retrieved 1 object from the…

Is infant looking behavior in ambiguous situations best described in terms of information seeking (social referencing) or as attachment behavior? Twelve-month-old infants were assigned to 1 of 2 conditions (Study 1); each infant's mother provided positive information about an ambiguous toy and an experimenter provided positive information. In…

In this study of early peer interaction, 32 first born infants (16 boys, 16 girls) were videotaped in pairs at 6, 9 and 12 months. Each 15 minute session consisted of Toys Present (TP) and Toys Absent(TA) conditions counterbalanced across dyads. Three questions were addressed: (1) Are infants as young as 6 months capable of interacting with a…

In two sessions, the duration and tempo of toy play of infants and reaction of frustration were measured. Correlations indicated a general relationship between response persistence during play and attempts to escape frustrating situations. (Author/CM)

The purpose of this study was to determine if sex differences were observable in 1-year-olds in response to their mother and in choice and style of play with toys. Thirty-two boys and thirty-two girls were put in separate rooms with several toys, several nontoys (door knobs, taped sockets, etc.) and their mothers. The infant's mother was to…

Tests the ability of 43 children, ranging in age from 20 months to 40 months, to discriminate between pictures of boys and girls and male and female adults. Compares children who passed this gender-task with those who failed it on three behaviors most often categorized as sex-typed: toy choice, aggression, and peer playmate selection. (HOD)

Evidence which suggests that pretend activities become increasingly independent of the presence of realistic objects is examined in this paper. Results of research on pretend behavior in children 1 1/2 - 2 years of age are described and analyzed. Striking changes in pretend behavior are shown to occur during the second year of life. Pretend play…

This booklet uses both words and photographs to describe behavior patterns typical of children from one to two years old and to suggest home play activities appropriate for use with children of this age. The booklet is organized into four age ranges: 12-15 months, 15-18 months, 18-21 months, and 21-24 months. Within each of these sections, a…

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…

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…
