Psychology is the study of behaviour and mental processes, and includes individual and social, human and animal, basic and applied aspects of these. The School of Psychology provides modules in all the main aspects of Psychology including Cognitive Psychology, Social Psychology, Developmental Psychology, Biological Psychology, Personality Psychology and Research Methods. The course satisfies the requirements for graduate membership of relevant professional societies (the Psychological Society of Ireland and the British Psychological Society).

Students might consider studying Psychology if they are interested in becoming an applied psychologist (e.g., clinical psychologist, educational psychologist, forensic psychologist, health psychologist etc.), a Psychology researcher, lecturing in Psychology or improving their general education by studying an interesting and useful discipline with careers of a more general type in mind, such as the media, IT or management.
