Philosophy Studying philosophy allows you to think about some of the great philosophical questions, in a clear, disciplined and systematic manner. It introduces you to the thinking of some of the great philosophers of the past and present, and illuminates the connections between diverse areas of human experience. It also makes you more aware of the assumptions that form the basis of your beliefs. Psychology Psychology is the scientific study of the mind, brain, and behaviour. It focuses on building and testing theories to help explain how people interact with each other and the world around them. Psychologists are interested in the way biological and social factors influence how we behave, and how interests and abilities differ from person to person. They also study how we perceive, think, and learn about the world around us. They examine how we communicate verbally and non-verbally, and how and why our mental abilities change across our lives. Psychology is an experimental and observational science, in which evidence from research studies is used to develop and evaluate theories.
