The Sleep Wake Cycle: Circadian rhythm - Biological Psychology [AQA ALevel]

If you want to improve your psychological knowledge in a way that is more fun than just studying and trying to memorise, I recommend reading a popular science book. You will be surprised how often the ideas in these books pop up in your actual course! And you’re far more likely to actually understand these ideas having read about their wider context.

My top 10 psychology(ish) books for psychology students.

thanks (once again) for these videos, Nick. Really informative and they really jog my memory in terms of the content for each topic. i like how they tell you exactly what you need to know without waffling on like some other people can do. super nervous for tomorrow, but these videos have been pivotal to my revision so thank you so much for all of your help!

Thank you so much for these videos!! I have ME/CFS and miss a lot of class sessions but these videos always help me keep up with work.

thanks for helping me cram revise for my mock

Excellent, thank you. Would you consider adding a new series where students can submit an essay and you'll pull it apart, tell us what's good, what can be improved and ultimately show us what'd you'd recommend?

[lucypayne]

Hi! I’ve been using the print outs you provide for the rest of the topics on the biological psychology page to revise this section however the link won’t work for me to download the three printouts on biological rhythms. Is there any other way I could access them? Thank you very much in advance!

[jasminehuynh]

can you use supporting research as evaluation

[AintEzBeinCheezy]

why is being exposed to more blue light a positive when in the Vetter research it was shown to disrupt endogenous pacemakers?

[croglodyte]

yo why is there so much reverb on his voice?
