Got questions about learning? I got answers. In this video, I take six questions about learning from Reddit and do my best to answer them.

00:00 How do you learn from lectures?
03:45 Is it possible for young people to learn complex skills on their own?
06:53 Is reading books for 30 minutes a day enough to learn anything?
09:06 Is watching videos a legitimate way to learn something?
13:43 Which apps or games can help improve cognitive function?
16:26 Does the brain of a 14-year-old learn faster?


For an interesting comparison of brain training to video games, check out: youtu.be/WYl-nZyoEXs. There’s references in the description for further reading.

For videos on learning complex skills, take a look at: youtu.be/WbUOY9ioIqw and youtu.be/aIPS4ugcanM

The testing effect (retrieval practice) is largely why I recommend the kind of review that I do. Check out this video for more on that: youtu.be/g0rg2xdnRPc. Plenty of good references in the link to that video.



For the research on the relative ineffectiveness of lectures, see: Freeman, S., Eddy, S. L., McDonough, M., Smith, M. K., Okoroafor, N., Jordt, H., & Wenderoth, M. P. (2014). Active learning increases student performance in science, engineering, and mathematics. Proceedings of the national academy of sciences, 111(23), 8410-8415. (currently at pnas.org/content/111/23/8410?lipi=urn%3Ali%3Apage%3Ad_flagship3_pulse_read%3B5ujlJ92ZQgC6PXO%2BbkuCcQ%3D%3D&utm_source=TrendMD&utm_medium=cpc&utm_campaign=Proc_Natl_Acad_Sci_U_S_A_TrendMD_0)

This isn’t the best reference on cognitive differences among different age groups, but it’s a good read: Brashier, N. M., & Schacter, D. L. (2020). Aging in an era of fake news. Current directions in psychological science, 29(3), 316-323. (currently at journals.sagepub.com/doi/full/10.1177/0963721420915872)
