Psychosocial development occurs as children form relationships, interact with others, and understand and manage their feelings. In emotional and social development, forming healthy attachments is very important and is the major social milestone of infancy. Attachment is a long-standing connection or bond with others. Developmental psychologists are interested in how infants reach this milestone. They ask such questions as: how do parent and infant attachment bonds form? How does neglect affect these bonds? What accounts for children’s attachment differences?

The time between a child’s second and sixth birthdays is full of new social experiences. At the beginning of this stage, a child selfishly engages in the world—the goal is to please the self. As the child gets older, they realize that relationships built on give-and-take. They start to learn to empathize with others. They learn to make friends. Learning to navigate the social sphere is not easy, but children do it readily.

While the child is learning about their place in various relationships, they are also developing an understanding of emotion. A two-year-old does not have a good grasp on their emotions, but by the time a child is six, they understand their emotions better. They also understand how to control their emotions—even to the point that they may put on a different emotion than they are actually feeling. Further, by the time a child is six years old, they understand that other people have emotions and that all of the emotions involved in a situation (theirs and other people’s) should be taken into consideration. That said, although the six-year-old understands these things, they are not always good at putting the knowledge into action. We’ll examine some of these issues in this section.

Children in middle childhood are starting to make friends in more sophisticated ways. They are choosing friends for specific characteristics, including shared interests, sense of humor, and being a good person. That is quite a departure from the earlier days of playing with the people in your group just because they are there. Children in middle childhood are starting to realize that there are benefits to friendships, and there are sometimes difficulties as well. In this section, we’ll examine some aspects of these relationships.

Adolescence is a period of personal and social identity formation, in which different roles, behaviors, and ideologies are explored. In the United States, adolescence is seen as a time to develop independence from parents while remaining connected to them. Some key points related to social development during adolescence include the following:

• Adolescence is the period of life known for the formation of personal and social identity.
• Adolescents must explore, test limits, become autonomous, and commit to an identity, or sense of self.
• Erik Erikson referred to the task of the adolescent as one of identity versus role confusion. Thus, in Erikson’s view, an adolescent’s main questions are “Who am I?” and “Who do I want to be?”
• Early in adolescence, cognitive developments result in greater self-awareness, the ability to think about abstract, future possibilities, and the ability to consider multiple possibilities and identities at once.
• Changes in the levels of certain neurotransmitters (such as dopamine and serotonin) influence the way in which adolescents experience emotions, typically making them more emotional and more sensitive to stress.
• When adolescents have advanced cognitive development and maturity, they tend to resolve identity issues more easily than peers who are less cognitively developed.
• As adolescents work to form their identities, they pull away from their parents, and the peer group becomes very important; despite this, relationships with parents still play a significant role in identity formation.
