Accepted to Linguistic Inquiry! I argue on syntactic grounds “some of the apples” is really “some apples of the apples” with NP-ellipsis. This explains which quantifiers and which modifiers (adjectives, prepositional phrases, relative clauses) can’t appear. Preprint: ling.auf.net/lingbuzz/009...

Online Now: The nativist–empiricist debate is broken
dlvr.it
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.

From the new issue: Pain: Modularity and Cognitive Constitution – Błażej Skrzypulec Abstract in alt text or read it here: www.journals.uchicago.edu/doi/10.1086/... #philsci #philsky
ABSTRACT. Discussions concerning the modularity of the pain system have been focused on questions regarding the cognitive penetrability of pain mechanisms. It has been claimed that phenomena such as placebo analgesia demonstrate that the pain system is cognitively penetrated; therefore, it is not encapsulated from central cognition. However, important arguments have been formulated that aim to show that cognitive penetrability does not in fact entail a lack of modularity of the pain system. This article offers an alternative way to reject the modularity of the pain system, which is independent from, but consistent with, the presence of cognitive penetration. I propose that given current knowledge regarding the functioning and the structure of the pain system, there are good reasons to accept that certain central cognitive mechanisms are part of the pain system. I argue that such a ‘cognitive constitution’ of the pain system entails that the pain system is not modular.

A conceptual schematic illustrating the logic of the studies. (A) Infants observe a central actor who shares saliva with one actor and does not share saliva with another actor. (B) From such observations, infants may infer and represent whether the actors are connected and how thick each connection is. (C) These representations support infants' expectations of who will respond to the central actor's distress.

🤖🧠NEW PAPER🧠🤖 (The result of an 8-year project!) LLMs seem very different from symbolic systems. Yet LLMs excel in symbolic domains (e.g., language/code/math). How do they do it? Our finding: LLM representations have implicit symbolic structure! Link in thread ⬇️ 1/n
Overview of the paper. 
Title: The Emergent Symbolic Structure of Artificial Neural Networks
Authors: Tom McCoy, Paul Soulos, Tal Linzen, Paul Smolensky
Left: Neural networks encode information in vectors (there is then an image of a vector), yet they excel at tasks long thought to require symbolic structure (there is then an image of a symbolic representation, specifically a syntax tree). How do LLMs do it?
Right: We find that LLM representations can be closely approximated with symbolic structures. This approximation lets us edit the structure of an LLM’s output by editing the structure of its internal representations, as shown. There is then an image of two edits to LLMs. In the first one, the original input is 3 + 6 * 8, with an answer of 51. But if we swap the positions of the 3 and the 6, the output becomes 30. In the second one, the original input is a Python command repeating the list [Z, U] three times, producing [Z, U, Z, U, Z, U]. But if we edit the input in a way that adds a Q at the end of the input, the output becomes [Z, U, Q, Z, U, Q, Z, U, Q].

Very proud to share this new work led by the amazing Marlou Rasenberg (not on here), with Joel Fischer and me doi.org/10.5281/zeno... We use #EMCA methods to study empirically how LLM users shoulder the burden of solving sequential trouble and end up restructuring their own aims & activities
Abstract: This paper investigates how a core component of human interaction – action projection – is realized in conversations with systems like ChatGPT, which are not able to recognize nor anticipate actions in a sequential sense. We ask what this means for users who engage in longer, multi-step projects built through incremental prompt-response pairs. We draw on Conversation Analysis to examine how early adopters of ChatGPT sequentially organise such interactions, using anonymised naturalistic interactions from the WildChat dataset. Our analysis reveals how action projection in LLM interactions is beset with interactional trouble. In turn, we document a set of practices we term ‘pre-emptive prompting’ that users develop to work around the trouble. In doing so, users employ a range of conversational methods including pre-sequences, prompt categorization, withholding executables, spelling out relevant next actions, eliciting displays of “understanding”, and creating slots for redirection in their attempts to complete their projects. Our work provides empirical evidence of how users interactionally accomplish the configuration work (Alcaras and Ricci 2025) needed to work around the discretization and cluttering that LLMs-in-use produce.Excerpt 10: ‘wouldnt you require both inputs’ wc_1211945; wc_usr_d2a27584b4185dda [conv_index: 359]
1 user : ok if i said i want to provide you with input A (which is an items description) and just assess its format and presentation then i provided you with input B (which is also a item desctiption for a similar item) but in a way diffrent format could you make the B input into A input
2 LLM: Yes, I can certainly help you with that. Please provide me with Input B, and I will try to make it resemble Input A in terms of format and presentation.
