Our daily lives are packed w complex behaviours: reading a novel & piecing together the plot; negotiating decisions w family... How do we build mathematical models of the underlying cognitive mechanisms? Our new preprint osf.io/d2v54_v1 argues for a community approach A 🧵 1/

Fresh out: a short review article where I give an overview of different ways that across-trial temporal structure is helpful in understanding cognitive models of decision-making

Als jullie morgen voor deze bezuinigingen stemmen, zijn het wél jullie bezuinigingen!

Duik niet laf weg voor je eigen keuzes
Vooropgesteld: de plannen van dit kabinet voor onderwijs zijn niet de plannen waar het CDA voor zou hebben gekozen, dat zullen het ook nooit worden. De bezuinigingen die overeind blijven zijn niet de onze. 3/8

Re: "this meeting could have been an #email"

Email can ALSO predict #burnout *at least* as much as meetings.

A study of 79 employees found time on BOTH meetings AND email predicted "overload" above other factors: doi.org/10.1287/orsc...

Any good advice on bot prevention for online studies?
We usually use well regulated subject pools, so haven't had a problem before. But a student is struggling with a study where she has to use social media networks to find pps with specific language backgrounds.

Dankbaar aan alle collega's en studenten in het land die vanmiddag in de stromende regen op het Malieveld stonden. (En een stukje extra dankbaar aan iedereen uit Groningen, Maastricht of Heerlen, voor al die uren extra reistijd)
De bezuinigingen op hoger onderwijs en wetenschap moeten van tafel, luidde de boodschap van meer dan twintigduizend studenten en medewerkers uit het hoger onderwijs. Minister Bruins werd aangeraden op te stappen. scienceguide.nl/2024/11/vol-...

To remember something (e.g., a list of groceries), you can repeat the items aloud or in your mind, to remind you. What if you are trying to recall locations? Do we analogously use glances toward them to boost memory? I don't think so, and here is some new evidence against this idea. 🧵 #psychscisky

Our researcher, PhD candidate Thomas Wilschut's study, shows that verbal responses eliminate disadvantages in vocabulary learning for dyslexic learners.

Read the blog to learn how these findings could reshape the way we teach dyslexic students:

Güven Kandemir, @sophiawilhelm.bsky.social, Nikolai Axmacher & me studied color memoranda in working memory with impulse perturbation and multivariate pattern analysis. We found some interesting disparities with memory for orientations. The paper is now out in iScience:

not reproducible ≠ wrong/false/fluke
reproducible ≠ true

not reproducible ≠ poor science
reproducible ≠ good science

reproducibility of results is not a reliable indicator of truth/research quality/epistemic progress.

replication of a poorly designed study is another poorly designed study.
