Psychology courses use APA (American Psychological Association) style for referencing. You can use the AWiP (Assessed Work in Psychology) document that is provided by your course as a first point of call. AWiP illustrates the basic elements of the style with examples. You can access the document here but you must use your University Google account for authorisation http://bit.ly/awip2019
APA has its own online tutorial. http://flash1r.apa.org/apastyle/basics-html5/index.html
