The personality of a person can be defined as a set of qualities, beliefs, feelings, thoughts, attitudes, emotions and ideas that distinguish him from others. Since very many years social scientists have been trying to find the reasons why people behave the way they do and how the personalities shape up. There is a widespread belief that if the factors responsible for shaping up a person's personality are controlled, right in the childhood itself, a person can have a desired, well-rounded personality. Social and Personality Development in Children There are some theories which say that the personality of an individual is directly linked to genes. However, then why do siblings develop a completely different personality? No one has yet found an answer to this question. Then there is another theory which says that it is the environment to which a child is subjected that makes up his personality. A child's parents, teachers, friends, acquaintances, his home environment, his school environment - all these have a great influence in shaping his personality. Lastly, the kind of experiences a person has, as a child, teen or a young adult, play a major role in determining his reactions, his feelings, his emotional make-up and the way he behaves. Parental Influence... Out of all the factors responsible for personality development, parental influence is the most important one. The way the parents behave with the child, how much he is allowed to socialize, the kind of culture he is subjected to by them, and the emotional make-up of his parents, all these have a great bearing on the child's mental growth. In early childhood, all children ape their parent's mannerisms. Children learn a lot about socialization from the way their parents interact with their friends, neighbors, acquaintances, etc. If the parents are social, the same traits will most probably be imbibed in the children. Thus, parents should take care to become good role models and provide the child with the best environment, where he gets ample opportunities to develop his personality. Home Environment... The first time a child begins to understand his emotions, is through his mother. A child learns about love, care, support and help, through her. Thereafter, he develops various kinds of emotions, both positive as well as negative. Happiness, fear, anxiety, jealousy, anger and shyness - a child starts displaying all these. Again, it is up to the parents to make sure that the child incorporates the positive emotions in his personality and stays away from the negative ones. A child needs both his parents, mother as well as father to develop his personality. An absentee father or someone who stays away from home for a long time, can have a negative influence on the child. To ensure that a child turns out to be a confident, positive person, there are some other things that parents should avoid, such as being too authoritative, trying to discipline the child in excess, scolding the child often, punishing him severely, criticizing the child, discouraging him, comparing him with others and giving preference to one child over the other one. School Environment... Besides the home environment, a child's school environment too plays a major role in shaping a child's personality. Once a child starts going to school, he learns how to interact and deal with his peers. He comes to know how to engage in "playing" according to the rules and regulations. He gets educated, learns how to read, write and communicate effectively. A child's personality is greatly influenced by the way he is treated at school, both by his teachers as well as his peers. Culture... Influence of culture in personality and social development cannot be ignored too. For instance, a child brought up in western countries is taught to be individualistic and competitive, while children brought up in Asian, African and South American countries are taught to be cooperative. According to psychiatrist Erik Erikson, there are various phases that a child passes through such as infancy, toddlerhood, preschool and school age. Each of these stages has its own share of problems and challenges, which a child has to overcome, with his parent's assistance, to turn out to be a well-developed personality.
