Object exploration is considered a driver of motor, cognitive, and social development. However, little is known about how early childhood education and care settings facilitate object exploration. This study examined if children's exploration of objects during free play was facilitated by the use of particular spatial components (floor, tables,…

To date, studies using cross-sectional methodologies make up a majority of the literature surrounding children with autism spectrum disorders and participation in physical activity and screen time. Longitudinal studies are needed to examine how physical activity and screen time behaviors co-develop for children with and without an autism spectrum…

This study represents a quasi-experimental test of the role of early social-emotional experience and adult-child relationships in the development of typically developing children and those with disabilities birth to 4 years of age living in orphanages in St. Petersburg, Russian Federation. The three orphanages in the current study were selected…

A study of three students (ages 9-14) with autism investigated whether deficits in deceptive play skills are general to all persons with autism and if these deficits can be overcome through repetitive reinforcement techniques. Results found the students could learn to deceive, even without formal intensive training. (Author/CR)

A study investigated the nature of the social construction of play events by a group of twelve 4- and 5-year-old children and the ways in which these play constructions are maintained over an extended period of time. The 5-month study was conducted in a nursery school classroom during the children's self-selected playtime. Data collection included…

This experiment investigates the relation of a free play experience to subsequent performance on problem solving tasks among children aged 4 to 10. Ninety children were divided into 3 age groups and were assigned in pairs of free play and non-play treatment conditions. Children were paired by block design test scores to control for perceptual…

Describes factor analysis of preschool children's play behavior, as measured by the Smilansky-Parten play matrix. Varimax rotation solution suggests three factors: Dramatic-Constructive Play, Solitary Behavior, and Functional-Constructive Play. Study suggests that these factors represent constructs of preschoolers' play. (Author/RWB)

Examined the underlying structure and factorial validity of the Children's Playfulness Scale in evaluating preschool children's behavior. Found that factor loadings, factor variances/covariances, and error variances/covariances are invariant across calibration and validation groups, indicating the good cross-generalizability of the scale. (JPB)

Children (N=408) from three experimental infant schools in Israel were observed during their free play for three consecutive weeks, using observational categories based on Parten's (1932) work. Findings based on 2,157 observations provide norms of social behavior and organization for ages five to seven, an age group which was not studied…

Results indicated that different types of play environment strongly influence preschool children's types of social play and play group size. Differences in cognitive level and social egocentrism influenced the choice of play environment. (Author/DB)

Effects of fenfluramine on autistic children, aged 7-16, were examined in double-blind testing with placebos. Serotonin levels, intelligence and behavior tests, videotaped free play data, and other tests were used for assessment. Serotonin decreased with administration of fenfluramine, and increased with reinstatement of placebo. No tests…

To investigate the development of preschoolers' social-cognitive play behaviors, ten preschoolers (two, three and four years old) were observed in their classrooms on 15 occasions by a time-sampling schedule. Social-cognitive behavior coding (Parten and Smilansky) indicates that children's play became more social as they grew older. (Author/PN)

Ten language-impaired children, aged three-four, were observed playing with toys and with objects requiring object transformations for play. Chronological age-matched normal subjects performed more object transformations than either the language-impaired subjects or children matched for mean length of utterance. All children performed more object…

Explored fathers' specific contribution to their children's attachment representation at various ages. Found fathers' play sensitivity to be a better predictor of the child's long-term attachment representation than the early infant-father security of attachment. (Author)

Study of same-sex play networks found that between ages four and six, the size of girls' play networks decreases along with the number of girls excluded. Although results did not confirm the hypothesis that the size of boys' play networks increases, there was a trend for boys in the older classes to exclude fewer playmates from their networks. (AA)
