History of Psychology
The following chapters were the final products in an undergraduate History of Psychology course. This work is licensed under a Creative Commons Attribution-NonCommercial 4.0 International License. These are still fairly rough, so please contact me if you'd like to contribute to the improvement of, or addition to, this body of open access material for History of Psychology.
I really like and use Danielle Navarro and colleague's open-access Statistics textbook. It is available in 3 versions depending on the stats software you prefer to use (all open-access as well).
I also really like and use Rajiv Jhangiani and colleague's open-access Research Methods textbook.
