Social skills and social competence play a crucial role in children's interpersonal relationships and behavior. Social skills encompass specific behaviors such as conflict resolution and tolerance, while social competence encompasses a wide range of knowledge and skills related to behavior in social situations. Prosocial behavior, which includes empathy, caring, and morality, is an important aspect of human relationships. While many of these traits are associated with society, they have roots deeply embedded in our biological and evolutionary history. In this final paper, social competence in children was explored, with an emphasis on its history and significance. Additionally, the development of prosocial behavior in children was investigated. The research was conducted through a survey among children aged three to six, in both integrated and non-integrated groups, who answered questions about social skills and prosocial behavior. The goal was to raise awareness about the importance of social competence and prosocial behavior in children and to encourage positive changes in their interpersonal relationships. Children in both groups exhibited varying preferences in playing with peers, inviting friends to birthday parties, and sharing toys. Additionally, different approaches to helping and comforting sad friends were observed among the children. The definition of kindness varied, with some children associating it with good behavior and love for others, while others saw kindness as a gesture of affection towards parents or friends. This diverse set of responses highlights differences in social interactions and values among children in integrated and non-integrated groups.
