Why Cant People Solve These Simple Problems? Benjamin Keep, PhD, JD 2024-07-10 | The cognitive reflection test was meant to measure one thing: the tendency for someone to stop and think before giving a quick answer. The simplicity of the test made it a widely used measure for critical thinking. But some clever experiments illustrate that the CRT is not so simple after all.00:00 Introduction00:19 The CRT problems1:20 The structure of CRT problems3:04 Some hints about what's going wrong4:53 The structure of insight problems6:27 Explanation Number One7:57 Explanation Number Two8:57 Explanation Number ThreeI'm launching a membership site.

G., & Scherer, L. D. (2019). Evaluating the cognitive reflection test as a measure of intuition/reflection, numeracy, and insight problem solving, and the implications for understanding real-world judgments and beliefs. Journal of Experimental Psychology: General, 148(12), 2129–2153. doi.org/10.1037/xge0000592This is the (classic) paper that introduced the CRT as a measure of reflection. Frederick, S. (2005). Cognitive reflection and decision making. The Journal of Economic Perspectives, 19, 25– 42. http://dx.doi.org/10.1257 089533005775196732. It also includes correlations between the math section of the SAT and the CRT (.46) vs the verbal section of the SAT and the CRT (.24).On the CRT’s correlation to tests measuring numeracy being about .5, see Cokely, E. T., Galesic, M., Schulz, E., Ghazal, S., & Garcia-Retamero, R. (2012). Measuring Risk Literacy: The Berlin Numeracy Test. Judgment and Decision Making, 7(1), 25–47. doi.org/10.1017/S1930297500001819On the associations between reflection/analytical thinking and various beliefs, see Pennycook, G., Fugelsang, J.

Current Directions in Psychological Science, 24(6), 425-432. doi.org/10.1177/0963721415604610This mentions some of the earlier results correlating CRT performance to rational thinking, but also extends the CRT to a seven-question test. The four added questions are probably even more reliant on numerical ability than the first three. Toplak, M. E., West, R. F., & Stanovich, K. E. (2011).

Learning Foreign Language Vocabulary - The Fundamentals Benjamin Keep, PhD, JD 2023-12-07 | Some thoughts on learning foreign language vocabulary.The “Chinese is Hard” podcast: open.spotify.com/show/6DdGLH8neJoAkggOZu4VrNWilliam Hart’s Youtube channel: youtube.com/@will3267Danyo Pang’s Youtube channel: youtube.com/@thedanyopang00:00 That's a lot of words00:24 Different kinds of vocabulary words2:06 Word mapping between languages3:16 Vocabulary goes beyond words6:25 A story about prior knowledge9:22 Learning words by example and in context10:31 Flashcards12:22 Comprehensible input13:50 Pushed outputSign up to my email newsletter, here: http://www.benjaminkeep.comAcknowledgements:Definitions of “chew” comes from dictionary.com; definitions for “hard,” “take for granted,” and "repetition" come from Merriam-Webster, slightly adapted.References:The observations in this video are a mish-mash of my own personal experience and my reading of the literature on language learning. The best survey of that literature that I know of is How Languages are Learned by Patsy Lightbrown and Nina Spada. The 4th edition is here: bookshop.org/a/91541/9780194541268 (bookshop links are affiliate links, so if you purchase through this link, I do get a small commission; I would try to find this from your local library, though).It’s written with foreign language teachers in mind (not necessarily foreign language students), but hits on many of the key ideas, mentions a lot of great studies that I won’t enumerate here, and offers a relatively balanced portrait of the research on language learning.The 10,000 word estimate I mentioned at the beginning of the video is low and I wish I would have been more accurate. A lot depends on how you’re defining a word and how you define what “knowing” means. This is a solid paper on estimating the vocabulary of native American English speakers: Brysbaert, M., Stevens, M., Mandera, P., & Keuleers, E. (2016). How Many Words Do We Know? Practical Estimates of Vocabulary Size Dependent on Word Definition, the Degree of Language Input and the Participant’s Age. Frontiers in Psychology, 7. frontiersin.org/articles/10.3389/fpsyg.2016.01116.The upshot is that they estimate about ~11,000 word families and 42,000 lemmas on average. A lemma is a root word that you can derive into other things (baked, bake, baking would not be three separate words - just one lemma). Word families are larger groups of related words with similar forms and related meanings.Comprehensible Input is one of the main ideas in Stephen Krashen’s Monitor Theory. This is the classic piece that lays it out: Krashen, S. (1981). Second language acquisition. Second Language Learning, 3(7), 19-39. https://www.academia.edu/download/35238869/second_languge_acquisition_and_learning.pdfThe idea of pushed output comes from Merrill Swain and her studies of proficiency in immersive classrooms. She's got a lot to say on it over the years, but here's a representative example: Swain, M. (1997). Collaborative dialogue: Its contribution to second language learning. riull.ull.es/xmlui/bitstream/handle/915/30603/RCEI_34_%281997%29_07.pdf?sequence=1There’s much more to say about comprehensible input and pushed output, and I’ve got plans to release videos on those two ideas at least.

The specific excerpt, was taken from the first lecture on aggregation. coursera.org/lecture/model-thinking/aggregation-UWXGF. I definitely recommend Scott Page’s work, especially if you’re interested in social science and social dynamics.The "taking a test" example came from an MIT course on differential equations: https://ocw.mit.edu/courses/18-03-differential-equations-spring-2010/resources/mit18_03s10_ex1/.REFERENCESOn attention during lectures. The basic take-away is that passive learning during lectures is similar to a vigilance task (asking people to monitor for low frequency signals from a background of noise - radar monitoring for instance). 10-30 minutes in, steep attention decrements.Young, M. S., Robinson, S., & Alberts, P. (2009). Students pay attention!: Combating the vigilance decrement to improve learning during lectures. Active Learning in Higher Education, 10(1), 41–55. doi.org/10.1177/1469787408100194If you are a teacher looking to improve student learning during lectures, this piece from almost 40 years ago still holds up.

A Simple Way to Learn Complex Skills Benjamin Keep, PhD, JD 2023-03-15 | Sometimes we have to learn very complex skills that can't be broken apart into more basic skills.

The idea was to support learner's focus on part of the game, but it also meant that there's more than one difference between the control and the other groups. The enhanced display could explain some of the difference between the control group and the other groups, but doesn't explain the differences between groups 2 and 3 and group 4. And the variable-priority approach (what I call rotating focus) that the study helped establish is well-supported by other studies as well - see the meta-analysis in the reference section for more support.ACKNOWLEDGMENTSStarcraft clip from LowkoTV: youtube.com/watch?v=kz9M2uYcFyESpace Fortress mobile game footage from: play.google.com/store/apps/details?id=com.mgmamac.space_fortress&gl=USSpace Fortress DOS game footage from: classicreload.com/space-fortress.htmlYou can play an updated version of the original Space Fortress game at brainturk.com/space-fortressREFERENCESThis video is based on the paper below.

Psychological bulletin, 140(6), 1432. bit.ly/3VwGpIIThere's quite a bit of support for the idea that you want to be operating at a "high level" (e.g., synthesizing, applying, critiquing) early in the game. It's not like you need to learn all these rote facts first. A point that Justin makes eloquently in his video on encoding. The piece below is a great discussion of that.Agarwal, P. K. (2019). Retrieval practice & Bloom’s taxonomy: Do students need fact knowledge before higher order learning?. Journal of Educational Psychology, 111(2), 189. bit.ly/3T5Va3rSome have argued that retrieval is only good for simple materials (like remembering new vocabulary words) and not complex materials (like understanding how Newtonian physics works). Although many of the early studies do focus on "simple" materials, there's plenty of studies that establish the effect of retrieval is just as strong for complex materials.Karpicke, J. D., & Aue, W.

Appetite, 128, 138-144. sciencedirect.com/science/article/pii/S0195666318300011How portion size effects caloric intake is still disputed. It seems like there's some anchoring involved (the initial portion suggests what is normal or appropriate) and bite size may play a role as well.Herman, C. P., Polivy, J., Pliner, P., & Vartanian, L.

It's still a "may" though. The effect seems quite vulnerable to user awareness. So if participants are aware that they're in a food study, researchers don't find an effect. Or if they're aware that they just changed their plates to reduce their consumption, you don't see an effect. But there is at least some suggestion that in the long-run, as your awareness of the changed plates fades, you do end up reducing your consumption.Holden, S. S., Zlatevska, N., & Dubelaar, C. (2016).

The Surprising Truth About Note-taking During Lectures Benjamin Keep, PhD, JD 2022-09-21 | My argument on why the conventional wisdom on note-taking - particularly during lectures - is wrong.00:00 Introduction1:25 Does the writing process help us remember what we heard?1:44 Does reviewing notes later help us remember?2:07 The missing piece.2:55 An alternative method.3:56 Is taking verbatim notes useful?5:02 On paying attention to the right things.5:46 Taking notes during vs after a lecture6:46 My recommended practiceRyhan Hussain's channel: youtube.com/channel/UCg2u5o5dvS5iIu74rRO5x1wSign up to my email newsletter, Avoiding Folly, here: benjaminkeep.comReferences:A lot of the recent research on note-taking has been on whether taking hand-written notes or laptop notes are superior. The evidence for one being better than the other is a bit "meh". As mentioned, the idea that "verbatim notes are bad" seems less true for laptop note-takers.The opening quote comes from:Flanigan, A. E., & Titsworth, S. (2020). The impact of digital distraction on lecture note taking and student learning. Instructional Science, 48(5), 495-524. bit.ly/3RiWQWEThe second quote comes from:Morehead, K., Dunlosky, J., & Rawson, K. A. (2019). How much mightier is the pen than the keyboard for note-taking? A replication and extension of Mueller and Oppenheimer (2014). Educational Psychology Review, 31(3), 753-780. bit.ly/3CYdgzf Experiment 2, here, is also the one that I relate where "no note-taking" performed just as well as any of the note-taking conditions on immediate tests. It's unclear to me why they didn't also use a delayed measure with the no note-taking group. Also, looking at tables 3 and 4, you can see that if students took notes on material germane to the test, then they did well (my second concluding point).Another recent piece is here:Luo, L., Kiewra, K. A., Flanigan, A. E., & Peteranetz, M. S. (2018). Laptop versus longhand note taking: effects on lecture notes and achievement. Instructional Science, 46(6), 947-971. bit.ly/3Qw24xb. The introduction is a fair summary of the mixed evidence on the encoding hypothesis. Unfortunately, they only used immediate tests here, but there's some interesting material on the relative benefits of hand-written vs laptop notes.Below is a more direct test of my suggested approach. The results? Note-taking beats testing on immediate tests, but in two weeks testing wins. Testing even beats note-taking + review, suggesting that the storage function of notes is not particularly strong.Rummer, R., Schweppe, J., Gerst, K., & Wagner, S. (2017). Is testing a more effective learning strategy than note-taking?. Journal of Experimental Psychology: Applied, 23(3), 293. psycnet.apa.org/doiLanding?doi=10.1037%2Fxap0000134And here is another that finds no difference, even though students who took notes during the lecture took more relevant notes than those who took notes after the lecture.Haynes, J. M., McCarley, N. G., & Williams, J. L. (2015). An analysis of notes taken during and after a lecture presentation. North American Journal of Psychology, 17(1). bit.ly/3CUqAELAnd another old piece, same thing, no difference (only the measures weren't great).Eisner, S., & Rohde, K. (1959).

Three simple tricks to read textbooks more effectively Benjamin Keep, PhD, JD 2022-09-14 | Textbooks are a slog. But part of the problem is that we read them like we read other things, and we shouldn't. Here's how to up your textbook reading game.00:00 Introduction00:38 Sipping and chugging1:20 A technique for reading more actively2:43 A technique for incorporating free recall practiceSign up to my email newsletter, Avoiding Folly, here: benjaminkeep.comThe textbook pages are from "University Physics with Modern Physics" by Young and Freedman. If you're interested in learning physics on your own, check out: susanrigetti.com/physicsReferences:My recommendations here are a variety of what's called "spaced retrieval practice". There is a huge literature that spacing out study sessions (e.g., "sipping") provides long-term learning benefits. Here's a meta-analysis on verbal recall tasks: Cepeda, N. J., Pashler, H., Vul, E., Wixted, J. T., & Rohrer, D. (2006). Distributed practice in verbal recall tasks: A review and quantitative synthesis.

Here's some good papers on it:Karpicke, J. D., & Roediger III, H. L. (2007). Repeated retrieval during learning is the key to long-term retention.

Educational Psychology Review, 27(2), 317-326. http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.721.6502&rep=rep1&type=pdfFor my intro to retrieval practice, see: bit.ly/3djdOFv.My recommendation on reading the question before seeing the answer (e.g., "active" reading) is based on work in prior knowledge and illusions of knowing.Example problems tell you things, and there is "a time for telling". Seeing the canonical answer before first think about what the problem is short-circuits the learning process. Here's a few papers on this idea:Schwartz, D. L., & Bransford, J. D. (1998). A time for telling. Cognition and instruction, 16(4), 475-5223. http://aaalab.stanford.edu/papers/time_for_telling.pdfSchwartz, D. L., Chase, C. C., Oppezzo, M. A., & Chin, D. B. (2011).

3 Simple Lessons in Learning and Attention | Cognitive Load, External Focus, Distraction, etc. Benjamin Keep, PhD, JD 2022-07-27 | What does attention have to do with learning? A lot. Here's a very short summary of some of the more interesting findings in the research on attention and learning in three simple lessons.00:00 Lesson one - four stories about attention2:21 One way of thinking about attention and learning3:07 Lesson two - what controls attention?4:06 Lesson three - the roles of students and teachersSign up to my email newsletter, Avoiding Folly, here: benjaminkeep.comThe artwork I mentioned in the example comes from:Cut with the Kitchen Knife Dada Through the Last Weimar Beer-Belly Cultural Epoch of Germany by Hannah Höch (1919)The Elephant Celebes by Max Ernst (1921)Das Undbild by Kurt Schwitters (1919)The complex scientific figure is kind of a cheat: no one would use that as a powerpoint slide. It's more of an attempt to make a complete map of metabolic pathways in human cells.

How to prepare for a final exam | High school and college Benjamin Keep, PhD, JD 2022-07-13 | Oh crap. You’ve got a test. How are you going to study for it?00:00 Step #11:31 Step #23:00 Step #35:04 Tip #1: How to use visualizations5:40 Tip #2: On study groups6:26 Tip #3: Be reasonable during step 37:03 Open vs. closed book exams7:36 Multiple choice vs essay testsSign up to my email newsletter, Avoiding Folly, here: benjaminkeep.comMy advice here is based on a few lines of literature.Steps 1 and 3, which I recommend spending the most time on, comes from the research on free recall and the testing effect. These are just better study than rereading or re-writing your notes. Typical research findings are here:Karpicke, J. D., & Blunt, J. R. (2011). Retrieval practice produces more learning than elaborative studying with concept mapping. Science, 331(6018), 772-775. mrbartonmaths.com/resourcesnew/8.%20Research/Memory%20and%20Revision/Retrieval%20practice%20more%20effective%20than%20studying.pdfKarpicke, J. D., & Roediger III, H. L.

(currently available at http://psychnet.wustl.edu/memory/wp-content/uploads/2018/04/Butler-Roediger-2007_EJCP.pdf)My advice on the "outstanding questions" box is based on the literature on self-questioning and interrogation. It’s also supposed to help you with metacognitive knowledge (which helps you study more effectively because you know what you already understand and what you’re still struggling with). Example research findings are here:Dunlosky, J., Rawson, K. A., Marsh, E. J., Nathan, M. J., & Willingham, D. T. (2013). Improving students’ learning with effective learning techniques: Promising directions from cognitive and educational psychology.

Basically, they offload cognitive burden, they can be more specific than words (relating ideas and concepts in more precise ways), and they can help you identify patterns that you might not have recognized before.Schwartz, D. L., Tsang, J. M., & Blair, K. P. (2016). The ABCs of how we learn: 26 scientifically proven approaches, how they work, and when to use them. WW Norton & Company. (I’m referring to “V is for Visualization”. Great introduction to the research on learning more generally.)There are other ways of studying for tests, of course. But I think this is a pretty solid default method.
