Once again, I had a blast at #MCLS2025!
First time participating in a symposium so aligned with my research interests (“Representations of ordinality”).
Huge thanks to Maria Brandao for organizing it, and to all the brilliant speakers: @lillyroth.bsky.social, Francesco Sella, and Maria herself

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

The #MCLS2026 conference in Hong Kong was much fun and very inspiring 😍 I was happy to see again all the great researchers I got to know over the past years, and to meet many more 😊 Also had the chance to present my research on spatial mental representations of ordinality in letters 💪🏼

Happy Day 1 of #MCLS2025!

New publication on associations between ordinality and space 😍 Is the mental left-to-right representation of ordinality in letters rather based on long- or short-term memory? Find it out here: doi.org/10.1177/1747... Thanks @krzysztofcipora.bsky.social, @tuebang.bsky.social & all others 😊

Flyer for MCLS trainee February Special: Math Cognition in Context. Includes the following information: Join our trainee research chair, Nicholas Vest, for a discussion on math cognition in context. We'll be reading Draper et al. (2022) to explore the publication challenges faced by researchers studying child development in Majority World/Global South/non-WEIRD/low- and middle-income countries. The article examines publication bias, generalizability, contextual relevance (especially in measurement), the impact of the funding cycle, and offers recommendations for more inclusive journals (Draper et al., 2022, Infant and Child Development). This discussion is in collaboration with the Math Cognition Reading Group, and all members are welcome to attend.

Save the date for our February Special, Math Cognition in Context. Join us on February 24 at 11am ET / 8am PT / 4pm GMT / 5pm CET for a research article discussion, facilitated by Nicholas Vest.

One and only SNARC? Spatial-Numerical Associations are not fully flexible and depend on both relative and absolute number magnitude | Royal Society Open Science Numbers are associated with space, but it is unclear how flexible these associations are. We investigated whether the SNARC effect (Spatial-Numerical Association of Response Codes; Dehaene et al. 1993...

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

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 🥰🙌🏼

Unfortunately, this means goodbye to 3 Board members who greatly contributed to MCLS Trainee over the past 2 (or more) years.
A massive thank you to Co-chair @coolenilse.bsky.social, who will continue on as Past-chair, @rachelaconlon.bsky.social as Secretary, & @lillyroth.bsky.social as DEIJ Chair.

Registration for MCLS 2024 Conference closes TODAY, JUNE 5TH! Please register today on the website: www.the-mcls.org/conferences/...

We can't wait to see you at the end of the month!

@michaelanes.bsky.social Happy to hear you agree with our thoughts 🙌 We have not Ironmanned the color-word Stroop yet, but are currently Ironmanning the numerical Stroop and several other cognitive phenomena, see preregistration: osf.io/5nj6v Results yet to come!

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

In this study, we observed (1) that group-level SNARC, MARC, and Odd effects are not necessarily revealed by each individual, and (2) that stability of such phenomena over time cannot be taken for granted and can be very unsystematic 😱

In cognitive experimental psychology, we generalize a lot: Researchers often assume (1) that group-level phenomena are present in each participant, and (2) that observed phenomena in single sessions reflect typical behavior 🤔

THANKS SO MUCH to the Ironman-SNARC team: Verena, Stefania, Klaus, @tuebang.bsky.social , and (especially!) @krzysztofcipora.bsky.social 😊 And also thanks to our participants who showed much endurance in completing the parity-judgment task on 30 days in a row 😅

Happy to share our paper "Don't SNARC me now! Intraindividual variability of cognitive phenomena – Insights from the Ironman paradigm" published in Cognition! 😍 Check it out at: doi.org/10.1016/j.co... 👍

Our new paper on analog representation of angle magnitude is out: www.nature.com/articles/s41...
