Dealing with the human subjects such as psychology, sociology and behavioural biology, there are various disciplines in the behavioural science. Behaviour is a common thing in human as well as in adults. But now it is emerged as a disorder in modern humans. According to the person’s response given to the environment in appropriate manner psychology defines the state of responsibility as maturity level.
Adult and child behaviour has emerged as a field of study called Behavioural science. Misbehaving is a common thing among children but when it is quite different when compared to others then it should be noted. Children now a day are more stressed than ever before. When they continued to carry this stress and depression to their adulthood then they are at the risk of behavioural disorder. This makes the people insecure, emotional and irrational.
