Two horizontal lines with similar length

Can you tell which line below is longer? No? Then maybe humans cannot discriminate similar numbers with an approximate mental mechanism either. Read more about it at osf.io/6m4zw

Different sources of the numerical comparison size effect - Memory & Cognition In symbolic number comparison tasks, the numerical distance and size effects are largely influenced by the statistical properties of the stimuli. Here, we tested whether nonsymbolic number comparison ...

In a number comparison task, the size effect is, in fact, at least three distinct size effects with three corresponding generators. See more details about the anatomy of the number comparison size effect at doi.org/10.3758/s134...

I like this paper by @coolenilse.bsky.social

Very cool paper 😎

The Approximate Number System account assumes an imprecise mechanism behind the precise symbolic number comparison. This leads to various contradictions in the model. Read more about it at osf.io/6m4zw.

‘Time to review’ sidelining of education faculties in research Positive impact of channelling government funding into charity at expense of universities has yet to be proven, argues learned society

This THE article quotes an EEF spokesperson discussing a 2019 Educational Researcher article on RCTs I coauthored. But the EEF has misunderstood: “uninformative” does not mean “finds no difference”. www.timeshighereducation.com/news/time-review-sidelin...

Different evaluation methods may categorize subset-knowers as CP-knowers and the other way around. Picture below: how various methods categorize children differently. See details in psyarxiv.com/cz9ug

The SNARC effect may work only with symbolic numbers. It seems to work with nonsymbolic numbers when the task requires symbolic responses, such as "smaller"-"larger", but not without them. doi.org/10.1037/xhp0... or www.thenumberworks.org/discrete_sem...

Congrats! 🥳

Congrats! 🎉

Great to be back to Cracow after almost 10 years of academic „nomad life” :)

Flyer with images of the Washington State University and University at Albany logos, followed by the following text: Dear Colleagues, We (Dr. Mary DePascale, University at Albany, SUNY; Dr. Nicole Scalise, Washington State University) are currently conducting a meta-analysis on the effectiveness of early math interventions. We are currently requesting unpublished data on this topic to include in our meta-analysis. Specifically, we are looking for datasets that include: 1. Child participants (preschool age; ages 3 to 6 years) 2. An early math intervention (not including curricula) 3. A control or comparison group 4. At least one child math outcome collected after the intervention (e.g., posttest data) If you are willing to share your data or have questions about whether your data fits these criteria, please email us directly (mdepascale@albany.edu, nicole.scalise@wsu.edu) by November 9, 2025. Thank you! Dr. Mary DePascale & Dr. Nicole Scalise

✨Request for unpublished data✨ Meta-analysis on early (age 3 to 6 years) math interventions. Please reach out to me (Mary DePascale) or Nicole Scalise by November 9 if you are willing to share your data!

Should you use LLMs to summarize articles or conduct systematic reviews?

No!

1-LLMs can’t evaluate article quality
2-They overstate study results
3-WTH is the point of being an academic if we don’t even read each others work!!!

I’m looking for a study where someone has looked at accuracy on Raven’s matrices (or similar) items under extreme time pressure at the item level (not time pressure at the test level). I can’t find anything, but surely this study must exist?

Well, Francesco deserves credit sometimes I guess… 😉
