Psychosocial causes are always responsible for abnormal behaviour. The life experiences, problems, challenges, difficulties etc. play an important role to shape up the behaviour of an individual. Psychosocial causes include childhood deprivation or trauma, problems in married life, divorced family, improper behaviour of parents etc.
The effects of childhood experiences remain life long on the mind of an individual. Parents satisfy the needs of their children and provide them support, security and warmth. But if parents fail to do so, the child will start developing abnormal behaviour. Children deprived from their parents are more abnormal Sexually abused children or the children who have become victim of sexual aggressiveness develop more abnormal behaviour.
Family is the foundation for socialization. The process of socialization is important to make a child a social person. The interaction with other people start from home. The parents who are not able to have satisfactory adjustment with others, are not sensitive to others and try to take advantage of others can not develope proper socialization in their children. Moreover factors like family environment, residence and the member of family members also affect the normality of behaviour of the individual.
Thus, normality of an individual depends upon parents, family, peers, friends, residence, work-place and interaction with other people.
