Psychology:

Various schools of thought have argued for a particular model to be used as a guiding theory by which all, or the majority, of human behavior can be explained. The popularity of these has waxed and waned over time. Some psychologists may think of themselves as adherents to a particular school of thought and reject the others, although most consider each as an approach to understanding the mind, and not necessarily as mutually exclusive theories. In modern times, psychology has adopted an integrated perspective towards understanding consciousness, behavior, and social interaction. This perspective is commonly referred to as the biopschosocial approach. The basic tenet of the biopsychosocial model is that any given behavior or mental process affect and are affected by dynamically interrelated biological, psychological, and social factors. The psychological aspect refers to the role that cognition and emotions play in any given psychological phenomenon. For example, the effect of mood or beliefs and expectations on an individual's reactions to an event.
The biological aspect refers to the role of biological factors in psychological phenomena. For example, the effect of the prenatal environment on brain development and cognitive abilities, or the influence of genes on individual dispositions. The socio-cultural aspect refers to the role that social and cultural environments play in a given psychological phenomenon. For example, the role of parental or peer influence in the behaviors or characteristics of an individual.
Psychology encompasses a vast domain, and includes many different approaches to the study of mental processes and behavior. Below are the major areas of inquiry that comprise psychology..
