Final answer:
Corsaro and Eder describe children's relationships as 'Peer Culture,' which plays a significant role in socialization, especially as children develop their individual identities and become more influenced by their peers rather than just their family.
Step-by-step explanation:
Corsaro and Eder (1990) refer to the expanding, complex and multifaceted relationships of children as B. Peer Culture. Peer culture figures prominently as an agent of socialization for school-aged children, as they begin to develop their identities and separate themselves emotionally and socially from their parents. Kids in the playground teaching each other norms about taking turns typifies this socialization process. As adolescents, peer influence expands further to include behavior in larger social networks, potentially leading to the reinforcement of existing beliefs within 'echo chambers'.
