We are finishing simulations in Krakow at the Mathematical Cognition and Learning Lab for one of the largest simulation projects comparing mixed-effects models for RTs in Cognitive Science (~1.5M datasets; >7M models). Preregistration: osf.io/3s8cu

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

Beware! 😄🤭🤩 #MCLS2026 @krzysztofcipora.bsky.social @mclstrainee.bsky.social @mcls-official.bsky.social

Does SNARC only depend on relative number magnitude? Not necessarily! Our new Registered Report led by wonderful @lillyroth.bsky.social in collaboration with @tuebang.bsky.social, U.-D. Reips, J. Caffier, and A. Overlander royalsocietypublishing.org/doi/10.1098/...

37% of plots in Psychological Bulletin were raincloud plots in 2023! 😮

The Raincloud Quartet (new pre-print) All N = 111, M = 0.04, SD = 0.27. One-sided t-tests vs. 0 yield: t(110) = 1.67, p = .049. Only raincloud plots reveal the qualitative differences, preventing the drawing of inappropriate conclusions. How did we create the quartet? Where are data & code? 🧵👇

Some northern lights to brighten the bluesky

*A fancy journal* takes the @pci-regreports.bsky.social paper, charges £1400 (via institutional deal) for publishing it (AKA making a pdf of it). They keep sending back submission e.g., should be submitted as Stage 1 even though it is stage 2 ("this is their process")

Gave a talk on the flexibility of Spatial-Numerical Associations at the #MCLS2024 today 😊💪🏼 As you can read in our preprint, both relative and absolute number magnitude determine the SNARC effect: osf.io/79zsy/files/... 🤯🤔 Thanks to my collaborators, especially to @krzysztofcipora.bsky.social 🥰🙌🏼

Paper by Schmukle 19 (!) years ago came to the same conclusion: “Estimates of both internal consistency and retest reliability lead to the conclusion that the dot probe task is a completely unreliable measure of attentional allocation” (Via @ruben.the100.ci) journals.sagepub.com/doi/abs/10.1...

Paper alert: across 10k participants & 36 versions of the emotional dot probe task, task *reliability* cannot be distinguished from 0 (!). Raises very serious questions about the literature (how did so many find positive relations between this task and other variables). #PsychSciSky

Slowly emptying a file drawer. This Math anxiety dataset might be useful to some folks @mclstrainee.bsky.social

A new preprint led by @lillyroth.bsky.social Trying to tear apart long term memory and working memory ordinality for the letter SNARC @mclstrainee.bsky.social

Ironman SNARC published. Hope to bring some fresh look not only at SNARC literature. @mclstrainee.bsky.social

Our new paper on analog representation of angle magnitude is out: www.nature.com/articles/s41... Together with M. Hohol and P. Szymanek

True colors SNARCing: Automaticity of the SNARC effect - evidence from color judgment tasks: http://osf.io/aeyn8/

New preprint by wonderful @lillyroth.bsky.social . If you ever wondered whether there is a SNARC effect in the colour judgment task, you can learn it from this study (n > 700): osf.io/preprints/ps...

Hi all! @JCBahnmueller and I are searching for someone from numerical cognition, who has been involved in adversarial collaboration project? Anyone? @MCLStrainee

Finally our work on reporting reaction time pre-processing which started at @improvingpsych.bsky.social conference 2021 is out in print and open access!

New preprint: When and How to Deviate from a Preregistration osf.io/preprints/ps... I hope this helps researchers to reflect on the consequence of deviations from preregistrations by evaluating the test's severity and the validity of the inference.

Definitely a great place to be in April 2024, organised by wonderful @lillyroth.bsky.social and the Tuebingen group. @mclstrainee.bsky.social

just found this old screenshot saved as missing-not-at-random.png lol

My fantastic PhD @lillyroth.bsky.social got her first Reigstered Report in PCI accepted (stage 1) in a collaboration with @krzysztofcipora.bsky.social Ulf Reips and John Caffier. "One and only SNARC? A Registered Report on the SNARC Effect’s Range Dependency" rr.peercommunityin.org/articles/rec...

This term I have been overwhelmed by admin, management and meetings. It has sucked all the joy out of my job. In an attempt to improve things I’m doing a paper reading advent calendar. I’ll read and share one paper a day* from now until Christmas. See ⬇️ (*sometimes a skim read and not weekends!)

Hallo!

Peak District hike 😃

When you cite your own work

Publication Day! Moving experimental psychology online: How to obtain high quality data I hope this will be useful www.sciencedirect.com/science/arti...

🚨 New preprint with Robert Darby & Emily Farran. 📝 The Responsible Research(er) Recruitment Checklist A guide for applying responsible research assessment in recruitment materials; emphasising research content, citizenship & Open Research practices. #AcademicSky #ResearchPublishing osf.io/2kgny/

Quite high in my ranking of catchy titles 😃😃

The most helpful thing for new PIs Nature journals could do is waive the absolutely ridiculous Open Access fees of $11,690 that is absolutely impossible to afford for many early career folks.

Preparing a brief lecture on Aphantasia (inability to form visual mental images) for my students. What strikes me is that this phenomenon went largely unnoticed also because people having it were mostly thinking that this is what everyone has....

Coverage in Nature: “What if we ran a study where we tried to eliminate all those problems and do it as rigorously as possible?” The idea, he says, was to use best practices to identify a benchmark of replicability. www.nature.com/articles/d41...

When you discover new effects using preregistration, high power, & replicate faithfully with open materials, you get a replication rate of 86% & effect sizes 97% as big! Our new published paper with so many wonderful researchers: www.nature.com/articles/s41...

We know their game

Together with V. Prpic, L. Lugli, and M. Murgia we are co-editing this special issue on numerical cognition in Psych Research. Spread the word! @mclstrainee.bsky.social link.springer.com/collections/...
