ABSTRACT
Psychology is a broad field that includes those who talk with and counsel others with problems for example, clinical or counseling psychologists. The contemporary discipline of psychology is generally considered to have derived from two main sources: philosophy and science. Some in the natural sciences, and even in the psychological sciences, have suggested that psychology can be reduced to biology, in that all behavior and mental processing is based upon biological that is, nervous system activity. Within psychology, there are levels of explanation as well. Physiological psychology, which is the study of the biological bases of behavior, might be the most basic level within psychological science. Study of social behavior, developmental patterns, cognition, as well as the function of nervous system, is necessary for a well-rounded understanding of human behavior and mental life. From its beginning, psychology has wanted to be like the natural sciences of physics and physiology.
