This is a visual English summary of the FIRST part of the biological and cognitive psychology course at the VU Amsterdam (first years). Based on the lectures & the books (Goldstein: cognitive pyschology & Carlson: Physiology of behavior)
The second part is also up on my page you can buy it as a ...
I was super stressed and I decide to buy it since other students were praising it and let me tell you. This summary met that standard. I passed my course because of this summary. Worth every penny!
