Psychology - Is a distinct discipline which find its roots in medicine and philosophy. Psychology is a science which concerns itself with the study of behavior, both human and animal, and therefore interrelates with other disciplines such as philosophy, biology and sociology. Few realized that as the study of human and animal interaction involves how these organisms perceive the world around them and how they react to these perceptions, this interaction may be observed in all areas of human activity.
Psychologists therefore search for answer to the question why.
From this research they develop theories of human functioning, often developing new approaches to current knowledge. From this perspective it can be seen that both normal and abnormal behavior are the psychologists domain. However the cornerstone of psychological practice still revolves around the examination and treatment of mental and emotional problems whatever the trigger or area of concern. Be it stress related to the working environment, trauma or shock following a catastrophic life event or the development of a particular form of mental illness such as schizophrenia. Here from research, whether independently or within a multidisciplinary team, the psychologist attempts to offer answers and formulate treatment methods.
