Final answer:
The two groups of adolescents that spend the most time with peers are Populars and Connectors. These groups highlight the importance of peer interaction in the socialization process during adolescence.
Step-by-step explanation:
In recent research on adolescent social self-perceptions and time spent with peers, the two groups that spend the most time with peers are Populars and Connectors. Adolescents in these groups are typically very engaged in their social circles and prioritize peer interaction. These groups contrast with others who may not seek out peer interaction as actively, such as Loners or Isolates. Peer groups are essential for adolescents as they navigate the process of developing an identity separate from their families, exerting independence, and forming moral and ethical values. It's during this time that the socialization process is heavily influenced by peer interactions, though balanced by parental influence.
