This study compared Korean and American children on scaffolding by peers during dramatic play. Thirty Korean and twenty American 5-year-old kindergarteners participated. The data were analyzed by Spradly's (1980) Developmental Research Sequence (DRS), using qualitative methods. The results showed that the categories of scaffolding (theme and communication) occurred more frequently among American children than among Korean children. In both cultures, more capable peers scaffolded children during dramatic play and were able to extend the dramatic play.

Objective: The purpose of this study was to examine the influence of affective and cognitive empathy, and peer competence on behavioral problems among young children. Methods: The participants were 224 4- to 5-year-olds attending daycare centers in Gyeonggi-do. Children's empathy, peer competence, and behavioral problems were reported by their teachers. The collected data were analyzed using simple regression and three-step hierarchical multiple regression analyses. Results: The results showed that children who exhibited low affective empathy scored higher on peer acceptance and behavioral problems than children who had high affective empathy. This pattern of results was similarly found with cognitive empathy. Additionally, the effect of children's affective empathy on behavioral problems was fully mediated by peer competence, whereas the effect of children's cognitive empathy on behavioral problems was partially mediated by peer competence. Conclusion: These results suggest the need for peer-competence training based on affective empathy and training for both peer competence and cognitive empathy in reducing behavioral problems among young children.

This study was aimed to at examining whether the effects of cooperative learning on children's social competence and self-esteem would be different in terms of young children's intellectual ability. To this end, a total of 64 five-year-old children attending two kindergartens in Kyunggi-Do were selected to participated in this study. Each child was tested on the short form of K-WPPSI and fell into one of two levels (high or low). The children in the experimental group took part in thirty-five 30~40 minute sessions of cooperative learning, while the control group engaged in individual learning. The results were as follows : First, children who participated in cooperative learning achieved higher improvements in social competence and self-esteem than children engaged solely in individual learning. Second, there were no any significant differences in improvement in terms of social competence and self-esteem between the high and the low intelligence levels. On the basis of these results, it could be concluded that cooperative learning had a number positive effects upon the levels of young children's social competence and self-esteem.

The purpose of this study was to examine changes in the rate of occurrence of challenging behaviors in young children according to their increase in age. The study is based on the responses of teachers in child care centers(N=246). They were asked which 38 types of challenging behavior occur most among ages 2, 3, 4, or 5 in young children's classrooms. The major results of this study were as follows. First, the occurrence rates of young children's challenging behaviors were classified into 5 clusters; decreased(Cluster 1, Cluster 2, Cluster 3), maintained(Cluster 4), or increased(Cluster 5) according to increases in their respective ages. Second, the behaviors such as throwing tantrums and biting, evident in Cluster 1, decreased very rapidly from a very high occurrence rate by age 3. The classroom culture maladjustment behaviors such as running aimlessly around the classroom and shouting, apparent in Cluster 2, had decreased rapidly from a high occurrence rate by age 4. The intentional classroom disruptive behaviors such as dropping objects to create noise and the peer culture maladjustment behaviors studied in Cluster 3 decreased gradually from a rate of medium occurrence by age 5. These results revealed the discontinuity which a few young children exhibit. Third, hurting others, observed in Cluster 4 maintained a low occurrence rate from age 2 until age 5. Using inappropriate language and threatening others in Cluster 5 increased gradually from a low occurrence at 2 to a high rate of occurrence at age 5. By carefully examining the change of young children's challenging behaviors on the basis of objective data in terms of the continuity/discontinuity and increased/decreased rate of diverse challenging behaviors, we will be better able help teachers and parents to plan the instruction, prevention and intervention of young children's challenging behaviors.

The purpose of this study was to contrast young gifted children with ordinary young children in K-ABC profile. The subject were 51 young gifted children and 51 ordinary young children, 2 to 4 years of age. Data of children's K-ABC profile were analyzed by Correlation and Crosstabs. The main results of this study were as follows: First, in the case of ordinary young children, there were significant positive correlation among 'Mental Processing Composite' and all sub-tests of mental processing composite except 'face memory' test, 'Achievement Scale'. In young gifted children, there were significant positive correlation among 'Mental Processing Composite' and just four sub-tests of mental processing composite, and there were no significant correlation between 'Mental Processing Composite' and 'Achievement Scale'. Second, there were no significant differences among all sub-tests' strength and weakness in young gifted children and ordinary young children. Third, young gifted children got higher score in 'Sequential Processing Scale' and 'Mental Processing Composite' than 'Achievement Scale'. But in ordinary young children, there were no significant differences among all K-ABC' sub-scales.

The purpose of this study was to investigate children's understanding of beliefs by age, type of questions, and experimental conditions. The subjects were 72 children, 12 boys and 12 girls each at 3, 4, and 5 years of age. They were randomly assigned to "standard" or "disappeared" conditions. The results showed that children's understanding of other's beliefs differed by age. The children could explain other's behavior from other's belief, but they could not predict other's behavior from other's false belief. These differences were found only in the "standard" condition.

The purpose of this study was to investigate whether children's temperament and maternal control strategies were related to the self-control behaviors of 3-year-old children. The sample was comprised of 50 young children, ranging from 37 to 50 months of age, and their mothers. Mothers were asked to complete a questionnaire on children's temperament. Situational observation was conducted for obtaining data on maternal control strategies and for children's self-control behaviors in a resistance to temptation situation. All the subjects' activities were videotaped for 20 minutes. Differences were found in maternal control strategies and children's self-control behaviors by gender of child and by age and education of mothers. Relationships were found between children's temperament and maternal control strategies. However, children's temperament had an indirect effect on their self-control behaviors through maternal control strategies. The findings indicated that the self-control development of children in this sample were in a transitional stage.
