The purpose of this study is to reveal the effect of perspective-taking skills of six-year-old children on their social competences. Determined by two independent kindergartens at Yenisehir district in Mersin as study groups, 115 children (59 girls, 56 boys) in the age group of 6, constituted the study group of the study. In order to reveal the predictor effect of perspective-taking skill on level of social competence, the technique of simple linear regression analysis was used in the data analysis. According to the results, the cognitive perspective-taking skill of six-year-old children predicted variables of entering a peer group, reaction to provocation, teacher expectations, and reactive aggression in a statistically significant manner. However, the cognitive perspective-taking skill of six-year-old children did not predict variables of reaction to failure, reaction to success, social expectations, and proactive aggression in a statistically significant manner. In addition, perceptual and affective perspective-taking skills did not predict the variables of entering a peer group, reaction to provocation, reaction to failure, reaction to success, social expectations, teacher expectations, reactive aggression, and proactive aggression in a statistically significant manner.
