This inclination of hiding stuffs is natural in humans. This is an inbuilt mechanism for coping with a certain unpleasant situations or circumstances.
A working Psychologists cannot be self-taught and must undergo specific courses and degrees. There are many branches of Psychology that a psychologist can choose to specialises.
Some of the branches include:
1. Child Psychology
2. Cognitive Psychology
