Final answer:
The statement that prosocial behaviors increase during the preschool years is true. These behaviors, such as helping and sharing, are a critical part of children's social and emotional development. Altruism, a selfless form of prosocial behavior, grows with children's increasing understanding of social norms.
Step-by-step explanation:
The statement that prosocial interactions like helping and sharing behaviors tend to increase during the preschool years is true. During these years, children are rapidly developing socially and emotionally, which includes learning to navigate their relationships with peers. This development involves increased interactions that are positive in nature, such as cooperating, sharing, and helping others. Prosocial behavior is important for building social skills and relationships that are essential throughout life.
Altruism, which is a type of prosocial behavior, is characterized by selfless helping of others without expecting anything in return. This altruistic behavior is observed in children and continues to be refined as they grow and understand societal norms and expectations. Peer relationships become an important agent of socialization, helping to shape a child's ability to interact in a prosocial manner within society.
