1. Pure Branches:
Pure branches provide the theoretical frame work of the subject. These branches deal with formulation of principles, theories and suggest different methods for the assessment of behaviour. The pure branches also suggest certain techniques for the modification of problematic behaviour.
The important pure branches are:
a. General psychology:
This branch deals with the fundamental rules, principles and theories of psychology in relation to the study of behaviour of normal adult human beings. It explains various psychological processes like sensations, perceptions, emotions, learning, intelligence, personality, etc.
b. Physiological psychology:
This branch describes the biological basis of behaviour. There is a close relationship between body and mind; the functions of each other are mutually influenced. The functioning of the brain, nervous system, endocrine glands and their relation to cognitive, Conative and affective behaviour is explained in this branch of psychology.
c. Developmental psychology:
Human life passes through various stages of development from conception to old age. This branch explains the growth and development of various processes in relation to behaviour.
d. Child psychology:
Childhood extends from 2 to 12 years. This is a crucial period in the life. Future life depends upon development during childhood. Growth and development will be rapid during this stage. Child psychology deals with these aspects.
e. Animal psychology:
This branch deals with behaviour of animals. Many psychological experiments are conducted to know the functioning of mind in animals. Animals like rats, dogs, chimpanzees, pigeons, guinea pigs, cats are some of the animals used for experimentation.
Findings of these experiments are many times generalized to human behaviour also.
f. Abnormal psychology:
Today the life is complex. The individual is facing a lot of competition and experiencing frustrations and conflicts. Constant pressures in life are leading to psychological abnormalities. Abnormal psychology deals with various kinds of mental disorders, their symptoms and causes.

Social psychology deals with interrelationships of people among themselves, likes and dislikes of people, attitudes and interests, the prejudices and social distances people have, group behaviour, group cohesiveness, group conflicts, etc.
h. Parapsychology:
Some of the psychological experiences are beyond the reach of 5 sense organs. That is why they are called extra sensory perceptions (ESP) or sixth sense. Some of the phenomena studied in ESP are as follows
This is referred to as television, which is seeing the distant things mentally. We perceive at times some situations or things without the help of our eyes. In total – seeing things which happen beyond our visual field through mind is called clairvoyance.
