Objective: This study aimed to examine the predictors of indoor play behaviors using cluster analyses. Methods: Data from 963 children (age 4 years) who participated in the $5^{th}$ phase of the Panel Study of Korean Children, their parents, and their teachers were analyzed using K-means clustering analyses, F-tests and multinomial logistic regression analyses. Results: The clustering analyses revealed three distinctive profiles: positive-theme oriented, general-exploratory/manipulative, and negative-exploratory/manipulative groups. Child characteristics, including cognition, language, and social level, and teachers' age were significantly associated with the groups in a different way; the clusters were partially different in the gender and creativity of children, interaction level of teachers' interaction, classroom environment, and program types that children attended. Conclusion: Findings revealed three clusters of play behaviors and highlighted the importance of the ecological variables that determined the clusters.

The purpose of this study was to investigate the relationship between the quality of caregiver's behaviors and children's social behaviors. the quality of caregiver's behaviors were observed during indoor free-play time in the 8 classes at 7 child care centers. Forty children were selected from two classes of high quality caregivers and 2 of low quality caregivers based on the quality of caregiver's behaviors. Children's social behaviors were measured in terms of social competence, social maladjustment, and social interaction. results of the study were as follows: First, children of high quality caregivers were more socially competent than of low quality caregivers. second, there were no significant differences in social maladjustemnt according to the quality of caregiver's behavior. Third, children of high quality caregivers showed more positive and dependent interaction with caregivers high quality caregivers showed more positive and depedndent interaction with caregivers than of low quality teachers. Also, children of high quality caregivers engaged less in aimless behavior and negative interaction with peers than of low quality caregivers.

The purpose of this study was to examine children's dramatic play and dramatic play themes in the same-age and mixed-age kindergarten classrooms. The subjects were 45 children in three classrooms of 4-year-olds, 69 children in three classrooms of 5-year-olds, and 60 children in three mixed-age classrooms of 4-and 5-year-olds. Observations were conducted by videotape recordings. Observation periods were of five-minutes duration. There were ten observations of children's indoor free-play periods. Four-and five-year-olds in mixed-age classrooms were more likely to engage in group-dramatic play than 4-and 5-year-olds in same-age classrooms. Four-year-olds in mixed-age classrooms were more likely to engage in domestic and family, war/violence, school, animal, and vehicle play themes than 4-year-olds in same-age classrooms. However, 5-year-olds in mixed-age classrooms were more likely to engage in family and school play themes than 5-year-olds in same-age classrooms. 5-year-olds in same-age classrooms were more likely to engage in vehicle and animal play themes than 5-year-olds in mixed-age classrooms. 5-year-olds in same-age classrooms did not differ from 5-year-olds in mixed-age classrooms on the war/violence themes used during dramatic play. In terms of sex differences, boys were more likely to engage in violence, adventure fantage themes than girls. Conversely girls were more likely to engage in family/marriage static play themes than boys.

The purpose of this study was to examine children's social-cognitive modes of play in same-age and mixed-age kindergarten classrooms. The subjects were 45 children. in three classrooms of 4-year-olds, 69 children in three classrooms of 5-year-olds, and 60 children in three mixed-age classrooms of 4- and 5-year-olds. Observations were conducted by videotape recordings. Observation periods were of five-minutes duration. There were ten observations of each child's indoor free-play periods. Observational data were collected by the time sampling method with the social cognitive play behavioral checking list based on an adaptation of one devised by Rubin(1985). The data was analyzed by t-test with the SAS computer program. Four- and five-year-olds in mixed-age classrooms were more likely to engage in "complex" modes of play than 4- and 5-year-olds in same-age classrooms. Four-year-olds in same-age classrooms were more likely to engage in solitary-functional, parallel-functional, and group-functional play than 4-year-olds in mixed-age classrooms. However, 4-year-olds in mixed-age classrooms were more likely to engage in group-constructive, group-dramatic, solitary-game, and group-game play than 4-year-olds in same-age classrooms. Five-year-olds in same-age classes were more likely to engage in solitary-functional and parallel-functional play than 5-year-olds in mixed-age classes. Five-year-olds in mixed-age classes were more likely to engage in group-constructive, group-dramatic, and group-game play than their counterparts in same-age settings.

The purpose of this study is to examine the effects of early full-time nonparental care during infancy/toddlerhood on children's socioemotional behaviors during the preschool period. Subjects for this study were 105 three- to five-year-olds from middle-class families in the U. S. A. Children were assigned to one of three groups according to their early care history. Children's social interactions with peers and caregivers during indoor free-play sessions in day care centers were observed for 20 minutes. The head teachers rated the children's social and emotional behaviors on two questionnaires. Mothers completed the Attachment Q-sort for attachment assessment for the preschoolers. In addition, mothers were asked to fill out a questionnaire on their parenting practices. Children who had received full-time nonparental care during infancy and/or toddlerhood were rated by their teachers as being more intellectually competent than children who did not receive full-time nonparental care during first three years of life. They were, however, rated by teachers and were observed by the researcher as being more aggressive than children with no full-time nonparental care. These children were observed to engage in less wandering/onlooking behaviors than children who had not had any full-time nonparental care. Children's attachment security scores and dependency scores did not differ as a function of early nonparental care histories. When the effects of early care patterns, sex of child, and current attachment security to mothers on aggressive behaviors of the preschoolers were examined by a hierarchical regression model, then any "pure" effects of nonparental care and of attachment security on child aggression were minimal after controlling for family background, child care center quality, and maternal childrearing practices. Strong buffering factors for the preschool children (family characteristics, parenting styles, and high quality nonparental care) mediated a possible risk factor of early nonparental care and promoted optimal outcomes for the children.

The purpose of this study was to analyze toddlers' verbal and nonverbal interaction with their peers and caregivers according to the class size of child care centers in Seoul. The subjects of this study were 20, two-year-old(M=32.5 month) toddlers with peers and caregivers from child care centers in different class sizes, but with same caregiver-toddler ratio. Verbal and nonverbal interactions were videotaped during one hour indoor free play per child in the center. According to the class size, the results were as follows : 1) Toddlers in the small class played more cooperatively with peers, and uttered more regulative or directive words than those in the large class. 2) Toddlers in the large class were more aggressive than those in the small class. 3) Caregivers in small class expressed more empathetic behaviors to a toddler than those in large class.
