In early childhood, young children frequently engage in object-oriented play. According to cultural-historical activity theory, object-oriented play provides children with opportunities to learn about the characteristics and cultural applications of objects and materials. These characteristics are referred to as rules or affordances of objects and…

We examined whether self-restraint in early childhood predicted individual differences in 3 executive functions (EFs; inhibiting prepotent responses, updating working memory, and shifting task sets) in late adolescence in a sample of approximately 950 twins. At ages 14, 20, 24, and 36 months, the children were shown an attractive toy and told not…

Previously researchers identified a behavioral profile that predicted treatment response of children with autism to a specific behavioral intervention, Pivotal Response Training (PRT). This preliminary investigation sought to refine this profile by obtaining six participants matching the original nonresponder profile on all but one of the profile…

Interactive toys for children are becoming more popular for both play and educational purposes, yet an understanding of the dependent measures used to study such interactions has not yet been explored. This study takes advantage of the idea that robotic animals exhibit both living and pretend qualities, and are therefore ideal for studying…

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…

Differences in toy selection and play behavior of five preschoolers with Down's Syndrome and nonretarded preschoolers matched for mental and chronological age were examined. Toy selection was determined by length of time and frequency with which the child played with 12 toys in two 15-minute sessions. Analysis of play behavior considered child and…

One central aspect of children's behavior in play and in situations of response uncertainty may involve the degree to which the child considers available information and forms a plan to guide behavior. Twenty-five boys and 25 girls, aged 27 months, were observed in a 30-minute free play session in which mobility and time spent in sustained…

Claims about the relative holding-power and play-versatility of toys either low or high in amount of realistic detail, such as miniature metal cars, were tested in a solitary play environment with and without the use of props. Subjects were 36 middle-class preschool children. Results suggest that, when structure is varied within the toy prototype,…

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 selection of play materials has long been of concern to parents and educators. Many play materials simply do not engage children. In this study toys were openly displayed for free selection and play within a children's recreation center. Data were collected on the subject population, toy selection and toy usage. The results indicated that…
