All of this is not to criticize Hull, who gave ample credit to Tsai. But... I think we could cite Tsai a bit more often, when we discuss how people (and other animals) minimize the expenditure of effort. (5/5)

Many thanks to dr. Yong Wang and dr. Wei Chen at the Center for Brain, Mind, and Education at Shaoxing University for sending me Tsai's monograph. They published a lovely biography on Tsai in 2022 (which is the source of the portrait above). doi.org/10.1007/s132... (4/5)

Tsai's "law of minimum effort" (left, 1932) is super similar to Hull's "law of less work" (right, 1943). (3/5)

Tsai (1932) published a monograph titled "The laws of minimum effort and maximum satisfaction in animal behavior". The monograph describes data from 21 T-maze experiments. Experiments 1-13 show that, when given the choice, rats learn to choose the option that requires least effort. (2/5)

Clark Hull usually gets credit for coming up with "law of less work" (or the "law of least effort") in 1943. I recently learned that the Chinese psychologist Loh-Seng Tsai published the same idea 11 years before Hull. 🧵Short history thread (1/5):

Big 2024 announcement! The “Guide to Effect Sizes and Confidence Intervals” had a pretty substantial update and is slowly becoming the most comprehensive resource on effect sizes and confidence intervals. Here is a thread of some of the new additions 1/5 t.co/ByeSMQNJdp

I sometimes try to publish in work psych journals, and this is in line with my experiences: "Unfortunately, journals in industrial, work, and organizational psychology still fail to support Open Science practices" open.lnu.se/index.php/me...

My intuitions: Authors should know best which studies are the empirical cornerstones of their reviews. I would set a limit on the number of these (10?) and report the outcome in a table (which is checked by editors/methods experts). The outcome does not need to be pass/fail; could be more graded.

Erik Bijleveld @erikbij.bsky.social · 02/11/2023

... it to at least the key/central studies in their review.

Erik Bijleveld @erikbij.bsky.social · 02/11/2023

Cochrane has these elaborate tools for assessing risk of bias in primary studies (mainly for writing reviews about clinical studies with RCT designs). These are useful I think. It would be good to develop a similar tool to assess "Risk of nonreplicability", and then require authors to apply ...

Translating psychological verbal theories into formal testable models of differential equations: osf.io/kqyxa

This just came out: Three experiments suggest that specific and difficult task goals enhance sustained attention performance. 👁️👁️ I like how these authors applied theory from work psychology to their cognitive paradigm. link.springer.com/article/10.3...

This is a bit different from analyst/operator fatigue, because we are mainly interested in user/employee fatigue. But of course, I totally see that this is relevant for security/safety.

000

Very interesting. In one of our projects, we also try to model real-life security-related decisions (in the lab, e.g., think of decisions to use secure data transfer vs. taking a shortcut), and then see how these decisions respond to fatigue.

This is an interesting angle, thanks. I agree that the finding is not super surprising. For me, the most inspirational aspect of this study is the methodological approach, which allows for high precision in explaining and predicting fatigue.

Yesterday, we organized an internal "Boost Your Skills Day" at our institute. We had workshops on theory development, methods/stats, and OS. No external guests, just ~90 faculty and students learning from each other. The vibe was optimistic and warm. Can highly recommend.

I don't know whether the dynamics of fatigue during new tasks (when people are learning) is different from fatigue during old tasks (after learning). This is an open question afaik. However, boring tasks can still induce quite a lot of fatigue: europepmc.org/article/med/...

Erik Bijleveld @erikbij.bsky.social · 20/10/2023

That's a nice question. I don't have the answers but I can try to speculate a bit: I'd say cognitive fatigue is a unitary phenomenon, because it serves the same function in different contexts (i.e., it biases towards switching to different activities; and specifically, to low-effort activities)
