Psychology is the science of behaviour. It studies the way people and animals interact with the world and each other. This covers a wide range of topics.
Psychology attracts many students.
Some specialise in Psychology, and they complete BSc or BA degrees with Psychology as their major subject. Others take Psychology because it complements many degrees. For example, many students take some psychology to go with their degrees in Law, Health Sciences, Education, Philosophy, Management, Marketing, Neuroscience, Computer Science, Physical Education, or Consumer and Applied Sciences. Students can take just one paper, but you must do both before you can take Psychology papers at 200 level. Each paper has both lectures and a laboratory component.
