An absolutely *beautiful* paper by @urvi.bsky.social on a property of the count list that seems so trivial yet is quite difficult to discover! And yes, as things that come later, like first year project papers, are greater, they are very deserving of a party ;)

This paper is PACKED with lots of other info that I won't get into here, but I am *beyond delighted* to share it! It was my first pancake - a little wonky & rough around the edges but still served hot and delicious (hopefully)! You should read it because I had a REAL party to celebrate the work. 6/6

We found some interesting? weird? maddening? results. Kids could make comparisons like 24 vs 26 and 26 vs 28 w/o the ANS but couldn't do so when decade labels (28 vs 30) were implicated. In essence, their success was explained by their knowledge of the +1 relations b/w units (e.g., 4, 6, 8) 5/6

Urvi Maheshwari ツ @urvi.bsky.social · 06/10/2026
But larger numbers may be conclusive: If kids judge that twenty-six > twenty-four but can’t discriminate 26 v 24 objects, they’re likely using a principle to do so. And if kids are unable to make either judgment accurately, this probably means they don't know that later numbers are greater 4/6

Urvi Maheshwari ツ @urvi.bsky.social · 06/10/2026
Following weber’s law, we reasoned that it’s possible to compare sets of 4 v 6, but this seems a lot harder when the comparison is 24 v 26 dots. The logic goes: kids should succeed at both 4 vs 6 and four vs six by relying on non-symbolic number or a principle (as previous studies show). 3/6

Urvi Maheshwari ツ @urvi.bsky.social · 06/10/2026
In two studies, we compared two possibilities: (1) kids rely on analogical mappings b/w number words and sets to grasp LG: six = 6 dots, four = 4 dots, 6 dots > 4 dots, ergo six > four. Or (2) kids use the +1 relations b/w number words to infer LG: six comes after four, ergo six > four. 2/6

New w/ @drbarner.bsky.social in Cognitive Science! We explored how kids learn the “later-greater” principle — the idea that numbers that come later in a count are greater in magnitude. Turns out this simple property governing the count system doesn't come easy! dx.doi.org/10.1111/cogs... 1/6

One, Two, Three, Four… What's More? Successor Relations, not Mappings to Approximate Magnitudes, Support Learning the Later‐Greater Principle

Online Now: The nativist–empiricist debate is broken

The nativist–empiricist debate is broken
The nativist–empiricist debate has long organized cognitive science, framing cognitive mechanisms as either innate or learned. Recent advances in controlled rearing and scalable domain-general neural networks now allow this debate to be tested with unprecedented rigor, by raising newborn animals and deep neural networks under tightly matched developmental conditions. Strikingly, when pushed to this empirical limit, the debate does not resolve: the same developmental phenomena support both radical empiricism and radical nativism. We argue that this stalemate reflects a conceptual error. The debate conflates explanatory levels and ontological orientations, with nativists emphasizing stable symbolic structures and empiricists emphasizing the subsymbolic processes that produce those structures. We propose dissolving the dichotomy within a multilevel framework of cognitive development.

Aside from testing the MR view, we offer a new theoretical take on why kids fail. Kids conceptualize the goal of object retrieval tasks exactly as adults do betting. When we bet on horses, we don't spread bets across all options, but try to pick a winner. When FORCED to spread bets, kids succeed.

If minimal representers, one they commit to 1 exit of the Y-tube, they should choose randomly b/w the 2nd Y exit & the impossible tube. But if they reason about possibilities, they should choose both exits of the Y. We found that even 2½yos chose both ends of the Y, ignoring the impossible tube! 6/6

Urvi Maheshwari ツ @urvi.bsky.social · 26/05/2026
Here we asked kids to choose 2 locations for a reward from 3 locations, where 1 was impossible. Critically, kids were required to make both choices before knowing the outcomes of either choice, reducing the possibility of sequential simulation. 5/6

Urvi Maheshwari ツ @urvi.bsky.social · 26/05/2026
But in these tests, rather than knowing that the goal is to maximize rewards, kids may think that they have to correctly guess an object’s location. These diff. goals might yield diff. behaviors on Y-tubes. The 1st predicts use of 2 hands, but the 2nd predicts use of 1 hand under the “best bet”. 4/6

Urvi Maheshwari ツ @urvi.bsky.social · 26/05/2026
Critically, minimal representers believe that only 1 exit of the Y-tube is possible, and the other is impossible. On prior tests, kids don't appear to make a conceptual distinction b/w the 2nd exit of the Y-shaped tube (to which they have not committed) and a separate "impossible" tube (Fig). 3/6

Urvi Maheshwari ツ @urvi.bsky.social · 26/05/2026
On the minimal view, when reasoning about the existence of a reward in 1 of 2 locations, 3yos commit to 1 location for the reward in a pair, only considering the 2nd location when they have evidence that their 1st choice is wrong. This might explain why kids fail the 3-cups, but not a Y-tube. 2/6

Our point: cross-linguistic differences b/w groups are graded, rather than as binary. Instead of asking whether innumerate groups can represent exact number or not, the literature shows that there are subtle differences in how languages encode number, with downstream consequences for learning 4/5

Urvi Maheshwari ツ @urvi.bsky.social · 20/05/2026
Languages goes well beyond simply labeling numbers, and provides multiple conceptual resources: in morphology, words, & syntactic rules. Here, we discuss current & historical variability in how languages encode number at multiple levels, & how this variability impacts children learning to count! 3/5

Urvi Maheshwari ツ @urvi.bsky.social · 20/05/2026
Past studies w/ innumerate and semi-numerate groups tell us that learning language for large numbers is necessary for the ability to express exact number knowledge. But these studies don’t explain the precise role that language plays in the origin of this knowledge. 2/5
