Professor Anthony Walsh has compiled a comprehensive guide to psychology, full of curiosities, images and tutorials.
Some of my favourites include images of trepanning devices from the middle ages, a case study of Mollie Fancher, a curious patient from the 19th century and a Dr Walsh’s own guide to classroom decorum!
This is one of the most comprehensive online psychology resources I’ve discovered as yet, and certainly one of the most fun to browse through.
Good starting points are his pages on:
* Introduction to Psychology
* Abnormal psychology
* Statistical methods in behavioural science
Mind Hacks
