Evolution of Psychology:

1. Wundt of Germany first established an experimental laboratory in 1879 to study of conscious experience. They were called as structuralists.

2. William James developed a functionalist approach to/the study of human mind. He studied that instead of focussing on the structure of the mind, psychology should instead study what the mind does and how behaviour function in making people deal with the environment.

3. In 20th century a perspective called Gestalt psychology emerged in Germany as a reaction to the structuralism of Wundt. The Gestalt psychologists believed that what we experience is more than the inputs received from our environment.

4. Around 1910, John Watson rejected the ideas of mind and consciousness as a subject matter of psychology. According to him scientific psychology must focus on what is observable and verifiable. Thus he believed in behaviourism.

5. Sigmund Freud viewed human behaviour as a dynamic manifestation of unconscious desires and conflicts. Freudi an viewed human being as motivated by unconscious desires for gratification of sexual pleasure and sexual desires.

6. Humanist such as Carl Roger and Abraham Maslow emphasized the will of human being and their natural striving to grow and unfold their inner potential.
