Psychology is the study of mind and behavior. Its subject matter includes the behavior of humans and nonhumans, both conscious and unconscious phenomena, and mental processes such as thoughts, feelings, and motives. Psychology is an academic discipline of immense scope, crossing the boundaries between the natural and social sciences. Biological psychologists seek an understanding of the emergent properties of brains, linking the discipline to neuroscience. As social scientists, psychologists aim to understand the behavior of individuals and groups.
A professional practitioner or researcher involved in the discipline is called a psychologist. Some psychologists can also be classified as behavioral or cognitive scientists. Some psychologists attempt to understand the role of mental functions in individual and social behavior. Others explore the physiological and neurobiological processes that underlie cognitive functions and behaviors.
As originally formulated by social psychologists Henri Tajfel and John Turner in the 1970s and the 1980s, social identity theory introduced the concept of a social identity as a way in which to explain intergroup behaviour. "Social identity theory explores the phenomenon of the 'ingroup' and 'outgroup', and is based on the view that identities are constituted through a process of difference defined in a relative or flexible way depends on the activities in which one engages" This theory is described as a theory that predicts certain intergroup behaviours on the basis of perceived group status differences, the perceived legitimacy and stability of those status differences, and the perceived ability to move from one group to another. This contrasts with occasions where the term "social identity theory" is used to refer to general theorizing about human social selves. Moreover, and although some researchers have treated it as such, social identity theory was never intended to be a general theory of social categorization. It was awareness of the limited scope of social identity theory that led John Turner and colleagues to develop a cousin theory in the form of self-categorization theory, which built on the insights of social identity theory to produce a more general account of self and group processes.

During the early years of the 20th century, Rivers developed new lines of psychological research. He was the first to use a double-blind procedure in investigating physical and psychological effects of consumption of tea, coffee, alcohol and drugs. For a time he directed centres for psychological studies at two colleges, and he was made a Fellow of St John's College, Cambridge. He also participated in the Torres Strait Islands expedition of 1898 and his consequent seminal work on the subject of kinship. (Full article...)
