There are five approaches to psychology,
Cognitive Psychology
Cognition is the term used to describe a range of mental activities associated with thinking. Cognitive processes include reasoning, problem solving, paying attention and remembering.
Social Psychology
Social Psychology studies the way we interpret events that are going on around us and how we interact with one another.
Physiological Psychology
Physiological Psychology is the study of how the functions of the brain, in particular how the functions of the nervous and endocrine systems are related to the influence of behaviour and mental processes. Other aspects of physiology such as stress, looking at the way we respond to different circumstances and how by understanding those responses we are able to cope and possibly not let the stress affect us. Sleep, dreaming, consciousness and motivation are all part of the experience which psychologists study. Modern psychologists believe that physiology interacts with social cognitive and cultural influences to produce the wider picture not just one aspect.
Developmental Psychology
Developmental Psychology studies the way people develop and change throughout their lives, studying the biological, cognitive, social and emotional changes that occur in people from infancy to old age.
Developmental Psychology is interested in all aspects of psychology for example, social development looking at the development of intelligence and social understanding.
People do not stop developing at a certain age, for example, when they reach adolescence; they continue to change throughout their lives. Different stages of life produce different psychological demands on people and recent studies have been looking at how people respond to those demands.
Individual Psychology
Individual Psychology is the study of how we are all different from each other. This study is part of the psychological area of individual differences
