Define Psychology. Describe the basic and applied fields of psychology
ANSWER – INTRODUCTION : Psychology as a behavioral science shares common characteristics with other physical and biological sciences. All science has practical applications to deal with human problems and improve their quality of life. Engineering and technology have developed from the results of physics, chemistry and mathematics and made life easier and comfortable. Similarly, medical science has not only contributed significantly to fighting and eliminating many deadly diseases, but also treated / prevented many diseases. Psychologists have developed many techniques to help people to live a full and happy life by promoting / enhancing their psychological health.
Psychologists also cure and help to prevent various psychological and emotional problems (behavioral disorders). Sometimes, the problems of the world such as climate change, pollution, natural calamities, man-made disasters etc. are so widespread and serious that no one or two sciences can solve such problems. A group of scientists from different areas, therefore, come together and jointly manage such problems. It is known as ‘Transactionism’ (Rush, 1972). Due to the interplay of the results of various subjects, new areas of knowledge have emerged.
