I am recruiting graduate students! I'll review applications through both the Cognitive & Developmental areas. Interested students are encouraged to be in touch; I'd love to chat with you!

Earlier this year, Sam Clarke, Liz Brannon, and I published a paper taking a critical look at the phenomenon of *number adaptation*.

A reply by Burr, Anobile, and Arrighi is forthcoming in Cognition. You can see their reply here: https://t.co/p3WHLdMFef

Thrilled to share this new paper in JEP: General!

Visual coherence derived from natural statistics of object co-occurrence increases our perceived number, independent of semantic content.

"Rational Number Representation by the Approximate Number System"

📢 New from: @chuyanqu, Sam Clarke, Francesca Luzzi, & Liz Brannon

[Chuyan Qu @ChuyanQu]

These results vindicate key predictions of the hypothesis that the approximate number system represents full-blown rational numbers, though the discussion highlights numerous questions for future study.

[Chuyan Qu @ChuyanQu]

New paper out now in Cognition!

The approximate number system (ANS) enables organisms to represent the approximate number of items in a collection, but numbers of what kind? We present evidence that the ANS represents rational numbers.

Finally, we identify an intriguing asymmetry in participants' responses which is independently predicted by the idea that rational numbers are being represented using a part-whole format (like a fraction) rather than a part-part format (like a ratio).

Grateful for the collaboration with Sam Clarke, Francesca Luzzi, and Liz Brannon on this project!

[Sami Yousif @sami_r_yousif]

Our paper taking a critical look at *number adaptation* has been accepted at Cognition!

But that's not all: Cognition has also agreed to publish a short back and forth with folks who disagree with us, so stay tuned for that in the near future!

I'm starting a lab! This summer I'll join both the cognitive and developmental areas in the Psychology department at UNC Chapel Hill. I'm excited for and humbled by the opportunity. Here's a sneak peak at the lab: https://t.co/jK18tAdiTg

[Sami Yousif @sami_r_yousif]

Soon to be published in JEP:G, our first paper about the perception and cognition of *topological relations*. What we show here is that people readily distinguish (and remember, and match) items based on their topological relations. See examples below!

New preprint on an intriguing visual illusion of numerosity, with @michaelfbonner @DewindNick and Liz Brannon! Coherence derived from natural statistics of object co-occurrence increases our perceived number via low-level visual processing stages.

[Chuyan Qu @ChuyanQu]

Our results thereby support and refine the hypothesis that the approximate number system represents full-blown rational numbers, though our discussion highlights several remaining questions apt for future empirical inquiry.

[Chuyan Qu @ChuyanQu]

Excited to share our new preprint in which we (Sam Clarke & Liz Brannon) describe two new experiments (and a bunch of subsequent analyses) testing Clarke & Beck’s (2021) hypothesis that the approximate number system represents rational numbers.

and (c) we identify an intriguing asymmetry in participants' performance which is independently predicted by the idea that ratios are being represented using a part-whole format (like a fraction) rather than a part-part format (like a literal ratio).
