What’s new in the lab?
Travelling in difficult conditions: I am happy to see Maria Glaser and Ilse Coolen on their ways around Europe! While Maria just came back from a very exciting research stay with Christine Schiltz in Luxemburg (supported by DAAD), Ilse Coolen will stay in Tübingen for the next six months (Teach in Tübingen) – working wiht H.-C. Nürk. Exciting times!
I am running for the CNRS comité national for the upcoming five-year term. Vote for me if you can
Exciting tasks ahead: I am happy to announce that I will take over as the Editor-in-Chief for the Journal of Numerical Cognition! Many thanks to the MCLS board for their unanimous vote that expresses their trust in my vision for the journal. I will take on this responsibility together with six outstanding Associate Editors: Sara Hart, Tali Leibovich Raveh, Andreas Obersteiner, Joonkoo Park, Geetha Ramani, & Lieven Verschaffel!
One of these days – where you receive two mails from Nature publishing group, announcing the publication of a paper! Congratulations to
Kasia Rączy and Ana Luisa Pinho, who are the two first authors! It was fun.
Pinho, A.L., Amadon, A., Gauthier, B., Clairis, N., Knops, A. et al. (2020). Individual Brain Charting dataset extension, second release of high-resolution fMRI data for cognitive mapping. Scientific Data 7, 353

Another great moment: Within the workbook series for elementary schools at Nathan, I published a training manual on number comprehension for 2nd graders. The workbook aims at helping them to catch up with what they have missed out on during Covid19-lockdown! The manual combines standard classroom exercises with theory-driven exercises that are grounded on major principles of cognitive psychology that have proven important for understanding numbers: symbolic number knowledge, spatialization of numbers, focus on relevant information while suppressing irrelevant information, … Check it out here [disclaimer: it is in French ]
More good news: The fabulous Ilse Coolen, currently working as a post-doctoral research fellow at LaPsyDÉ has been granted a Teach@Tübingen Fellowship to join Hans-Christoph Nürk’s lab in Tübingen for the duration of 6 months. Congratulations Ilse! This will allow you to improve your German
Good news. The excellent Maria Glaser, currently working on her PhD thesis at the Experimental Psychology Unitt at Humboldt-Universität in Berlin, will join Christine Schiltz’s lab at the university of Luxemburg for 3 months, funded by the DAAD. Congratulations Maria! Looking very much forward to see the planned experiments being realized.
Great moment this week: I received some copies of my book!!
Numerical Cognition: The Basics provides an understanding of the neural and cognitive mechanisms
that enable us to perceive, process, and memorize numerical information. Starting from basic numerica
l competencies that humans share with other species, the book explores the mental coding of numbers
and their neural representation. It explains the strategies of mental calculation, their pitfalls and their
development, as well as the developmental steps children make while learning about numbers.
The book gradually builds our understanding of the underlying mental processes of numeracy and
concludes with an insightful examination of the diagnosis, etiology and treatment of dyscalculia.
Written in an accessible manner, the book summarizes and critically evaluates the major psychological
explanations for various empirical phenomena in numerical cognition. Containing a wealth of student-friendly
features including end of chapter summaries, informative figures, further reading lists, and links to relevant websites,
Numerical Cognition: The Basics is an essential starting point for anybody new to the field.
Good news: a paper has been accepted for publication in Quarterly Journal of Experimental Psychology. The first paper of my excellent PhD student Maria Glaser. Congrats, Maria.
Title: When adding is right – temporal order judgments reveal spatial attention shifts during two-digit mental arithmetic
Authors: Glaser, M. & Knops, A.

Title: A shared code for Braille and Arabic digits revealed by cross-modal priming in sighted Braille readers
Authors: Rączy, K., Czarnecka, M., Zaremba, D., Paplińska, M., Hesselmann, G., Knops, A. & Szwed, M.
A very warm welcome for Sixtine Omont who started as a PhD candidate on a project on the impact of domain-general factors on the acquisition of numerical competencies. I think we have a great team here!
back from a very interesting and inspiring ESCoP in Tenerife! See you all in Lille in two years time.
My book review on the ‘Introduction to Mathematical Cognition’ (Gilmore, Göbel & Inglis) will appear soon in QJEP. In a nutshell: Go read the book if you want to learn about the cognitive processes underlying mathematical cognition. The book covers basic numerical processes but also sheds light on how we conceptualize mathematical proofs, reasoning and algebra.
