sychology, Neuroscience & Behaviour (PNB) is the scientific study of the brain and behaviour. It is a science and a practice. As scientists, experimental psychologists conduct research to help understand why people think, feel, and behave the way they do. As clinicians, counsellors, or other practitioners, psychologists apply scientific understanding toward helping individuals, institutions, and society deal with issues relating to human behaviour and happiness. Whether you are interested in applied or scientific psychology, McMaster's undergraduate psychology, neuroscience & behaviour (PNB) program will give you a strong foundation for a career, or for further professional training.
