Reddit reviews Biological Psychology Pack

This book for Evolutionary psychology seems quite good as it is published by the Cambridge University Press, although I have not studied much on evolutionary psych. Also, anything by Frederick Toates is very well written, and we use this book in my biological psychology lectures at university and has a lot of neuroscience in it.

However, textbooks can unavoidably be quite expensive (even though you can sell them afterwards, getting the initial cash can be hard without a student loan). As an alternative, you might want to look at the A Graphic Guide series. I read the Introducing Psychology one during my A levels when I didn't have much money and found it really useful, although a bit short. There is one specific to evolutionary psychology, too.

Finally, a researcher at my university told me about this book, written by one of his lecturers, that helps you to understand more about the anatomy of the brain. It is a colouring book where you colour in each different region of the brain, but each page gets more specific about each brain region. The book isn't that expensive either. Here is a link. :)

Hope this helps, and good luck on your psychology quest :D
