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.  Economics There has never been a more exciting time to study economics. The ongoing consequences of the last economic crisis mean that the world urgently needs new thinking and new processes to meet the challenges of a changing economic climate. As an economics student, you will explore issues of economic stability, growth and development, all vital for economic forecasting and for influencing economic performance and policy. You will also examine the causes of economic growth and policies designed to promote prosperity, increase efficiency and reduce unwanted fluctuation in fiscal activity. There is a distinguished history of economics in Scotland that includes the work of David Hume and Adam Smith. Throughout your studies, you'll learn from world-leading economists before following in the footsteps of graduates who are in demand by national and international organisations.
