The main source for emulation is observation. Emulation is not possible without observation. Children observe the behaviour of their relatives, parents, siblings and neighbours minutely and then behave accordingly. They develope negative or positive attitude by observing others behaviour and likings and dislikings or people's negative or positive approach towards their behaviour. For example - When a child gives correct answer to the teacher's question, the teacher appreciates him which motivates other children. On the contrary when the child gives wrong answer and the teacher insults him, then it creates negative effect upon the child and other students. Such a situation developes negative attitude in children.
