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
My colleague Colin Foster has released a new resource designed for secondary mathematics teachers: “Teaching the Big Ideas in School Mathematics”. Available here: bigmathematicalideas.org
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...
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 ...

New Preprint! Non-symbolic quantity estimation may be characterised by many signatures, yet we typically focus on only a few of them.
Sharing first as a preprint because we are interested in feedback. If you have any thoughts or comments, please do get in touch! Enjoy :)

In this review with Natalia Dubinkina, we discuss how competing theoretical accounts of numerosity estimation often differ not only in the mechanisms they propose, but also in which behavioural phenomena they prioritise and attempt to explain.
We discuss what this means for evaluating competing models, what should be classified as a behavioural “signature,” and how the field may move towards greater consensus in the future.
Enjoyed reading this recent paper by @davidjpurpura.bsky.social and Jasmine Ernst. Really cool! :)
