Irrespective of the quality of the child's attachment to the caregiver as secure or insecure, unexpected separation and disruption of one's secure environment results in fear, anxiety, and disorganization of one's own behavior. Children who have experienced secure attachment relationships with a nurturing caregiver are the most resilient in reconciling the disruption and recovering from traumatic events. The disruption and loss experienced will most likely be more difficult to resolve for children who have experienced insecure attachment relationships. Children's daily experiences with parents affect their concept of self and relationships with others. Children with more positive relationships with peers express more positive behaviors.
More positive behaviors result in being better liked by peers.
In summary, the quality of parents' caregiving behavior initiates a process linked with the quality of peer relationships throughout childhood and early adolescence. Erickson proposed that social development is the result of the interaction between internal biological forces and external cultural pressures. As such, he proposed eight stages of development throughout the life span. For Erickson, the development of a psychologically healthy adult required the successful resolution of conflict at each developmental stage. He accounted for variation of emotional expression and behavior among individuals on their resolution of conflict along a continuum of healthy to unhealthy outcomes.
