Abused children have many emotional and psychological problems, and their awareness of self-prevention and confrontation tends to go to extremes. Abused children tend to be overly alert, keep a high degree of vigilance against any clues of harmful stimuli in the environment, and make quick attacks. Children who are physically abused or neglected also show more problems such as conduct disorder, attention problems, hyperactivity, destructive behavior and anti-social behavior. There are also serious difficulties in their peer relationship: on the one hand, such children show a high tendency to attack when interacting with their peers. They often respond to their friends' friendly ways with anger and attack, and often feel unhappy or angry instead of sympathizing with their peers' pain. On the other hand, these children show more social withdrawal behavior, especially in strange peer groups, showing an extreme lack of social skills. High aggression and high social withdrawal are two typical manifestations of abused children (especially physical abuse and neglect) in peer relationship. Such children are rejected and abandoned by their peers, leading to deeper and deeper social isolation. So that childhood abuse will leave a psychological shadow "curse", which will be buried deep in adulthood and difficult to cure.
