It is both a scientific discipline and a field of professional practice. Psychology encompasses a very wide variety of areas of human activity. Psychology is about how we learn, think, feel, remember, make decisions, cope with stress and relate to other people. In other words, Psychology is about the full range of normal life experiences. We can also learn how to improve the functioning of people who experience such difficulties.
Psychology is about the understanding of individuals, groups, organisations, society and cultures.
Applications of Psychology are as diverse as human activity itself.
