Forensic Psychology Course Podcasts

Many people have requested that I record audio versions of the studies for OCR A2 Psychology. So now everything you need is in this online psychology course.

The Forensic Psychology studies have all been recorded and added to the pages. Although it is possible to download these, it is a tedious process. So I have made all the files for the Forensic Psychology unit available in a downloadable zip file.

Now, you will be able to listen to these audio podcasts on the go and have no excuse for no revising!

This is one of the most influential and well-known studies in Psychology. It looks at conformity, which of course means that this study was conducted from a Social Psychological perspective.
