Motivation and Emotion is seeking a new Editor-in-Chief! 4-year term starting Jan 2025. Looking for someone with vision, experience in motivation/emotion research, and editorial chops. Deadline: Aug 1. Ready to shape the field? Details: morgan.ryan@springer.com

In our new RR, we will test whether and how mental fatigue impacts dishonesty:

I am already excited about the to-be-collected data.

Nice work led by Mara Bialas 👏 (also with @maartenboksem.bsky.social)

also obviously it's 1377

ashamedly i've never tried this (from Kahneman's 1973 'Attention and Effort')

I can confirm this (but I also really wanted it to happen)

You do not need to be Dutch to sign. If you simply care to preserve programs that have been leaders in rigor and reform in psychology, then signal your support for them to continue to thrive.

On rewarded actions and punishment-avoidant inactions: The action–valence asymmetry in face perception Although social interactions are ubiquitous, people often choose not to interact with others—for example, people may choose to not greet a stranger, t…

New paper in JESP: "On rewarded actions and punishment-avoidant inactions: The action–valence asymmetry in face perception.”

In four preregistered experiments, we show that inactions influence evaluations of faces. (1/5)

"First, the idea that a few minutes of self-control can leave you unable to resist temptation later has been thoroughly debunked. What remains is something far more mundane: fatigue."

Forthcoming at JEP: General is some more work from my dissertation. Over three experiments we test a popular model of cognitive effort aversion—the opportunity cost model, first proposed by Kurzban et al. (2013)—and find negligible support for its primary predictions. osf.io/preprints/ps...

'Since the establishment of that template, this norm of the 40-hour working week, Monday to Friday, we see that not much has changed'

I'm excited to share a new preprint: In a novel experimental paradigm, we found evidence that stress induces a computational bias during alcohol-related decision-making in favor of alcohol, but this bias was only sometimes strong enough to overcome competing considerations (e.g., taste preferences).

Since our first commissioning meeting my team and I have wanted to publish something about the tension between basic vs. applied research.

And now we have.

Please check out this must-read piece on the need to place greater value on applied research with concrete suggestions for how to do so 👇

We're in the process of making a (I think) nice online Mackworth Clock Task in OpenSesame. Will share it at some point.

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)

portrait of Loh-Seng Tsai

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):

Figure 1: Foraging trial diagram. On each trial participants chose to harvest the tree they were at (down arrow key) or travel to a new tree (right arrow key), during the travel they completed an effortful task, after which they arrived at a new patch with a replenished supply of apples. The tree is a green circle and rectangular brown trunk. The apples are red and lined up in a row on the bottom of the screen. There is a warrior avatar with a shield, helmet, and sword who jumps to harvest the apples.

I'm elated to share my PhD keystone paper published

Acute stress reduces effortful prosocial behaviour Participants under acute stress were less willing to exert a relatively low level of physical effort for actions that benefit another person compared to actions that benefit themselves.

Guide to Effect Sizes and Confidence Intervals

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

‚Science Advances‘ published our paper in which we asked:

Oh, wait, Bartley and Chute said this already *in 1945*.

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"
