4th CSLI Workshop on Logic, Rationality & Intelligent Interaction

The purpose of this ongoing initiative is to bring together researchers interested in contacts between logic, philosophy, mathematics, computer science, linguistics, cognitive science, and economics to discuss new dimensions emerging today, such as knowledge, information, computation, and interactive agency.

The workshop continues a tradition of discussion-oriented outreach meetings aimed at fostering community across disciplines and universities, including senior and junior participants.

5th CSLI Workshop on Logic, Rationality & Intelligent Interaction

This event continues a long-standing tradition at Stanford of annual workshops in logic, broadly conceived, aimed at fostering discussion across disciplines and universities, with the added goal of involving both junior and senior participants. The content of the workshop is drawn from the disciplines of logic, philosophy, mathematics, computer science, cognitive science, linguistics and economics, with an emphasis on exploring interdisciplinary contacts.

    Logic and Philosophy: Rachael Briggs (Stanford), Hanti Lin (UC Davis), John Perry (Stanford), Jennifer Wang (Stanford)

Regularization in Language Learning and Change

Language systems are highly structured. Yet language learners still encounter inconsistent input. Variation is found both across speakers, and within the productions of individual speakers. If learners reproduced all the variation in the input they received, language systems would not be so highly structured. Instead, all variation across speakers in a community would eventually be picked up and reproduced by every individual in the community. Explaining the empirically observed level of regularity in languages requires a theory of regularization as a cognitive process.

This talk will present experimental and computational results on regularization. The experiments are artificial language learning experiments using a novel game-like computer interface. The model introduces a novel mathematical treatment of the nonlinear decision process linking input to output in language learning. Together, the results indicate that:

  • The nonlinearity involved in regularization is sufficiently weak that it can be detected at the micro level (the level of individual experiments) only with very good statistical power.
  • Individual differences in the degree and direction of regularization are considerable.
  • Individual differences, as they interact with social connections,  play a major role in determining which patterns become entrenched as linguistic norms  and which don't in the course of language change. 

The Cognition & Language Workshop is a Geballe Workshop sponsored by the Stanford Humanities Center. We gratefully acknowledge the Humanities Center's support, and additional support from the Center for the Study of Language and Information.

CHALLENGES AND SUPPORT FOR VERB LEARNING

Abstract:

Young children the world over appear to expect that a verb presented in a transitive frame surrounded by nouns maps onto a causative meaning and is best associated with an event involving an agent and a patient. At the same time, however, they struggle when a verb appears in an intransitive frame in which two conjoined nouns occupying the subject position. This contrast in performance between the two syntactic environments has been replicated time and again across labs, and has led some researchers to conclude that the fault lies in children’s underdeveloped syntactic representations or in the heuristics they deploy to assign semantic roles to a verb’s arguments. However, I will present the results of a set of word learning studies demonstrating that not only do adults also flounder when presented with a novel verb in an intransitive frame, but when children are provided with semantic support for the form-meaning mapping in the form of an additional informative lexical item or distributional evidence concerning the intended interpretation of the syntactic frame in the discourse, they fare much better with the intransitive frame. These findings suggest that the problem may not be an immature grammar, but rather lack of sufficient information to narrow down the hypothesis space. Verb learning calls upon children’s syntactic, semantic, and pragmatic knowledge. When these aspects of the linguistic system work in concert, mapping form to meaning is facilitated.

"The Rise of the Neural Subject"

Abstract:

    How did we come to think of the self not as soul, psyche, or mind but as brain and nervous system?  Though much talked about in recent popular-science books such as V. S. Ramachandran’s The Tell-Tale Brain: A Neuroscientist’s Quest for What Makes Us Human, Patricia Churchland’s Touching a Nerve: The Self as Brain, and Joseph LeDoux’s The Synaptic Self, the idea is hardly recent.  An understanding of its history may help us to better understand its present and future.

    After sketching a broad history of the formation of this conception of the self, this talk will pay particular attention to cultural transformations in Western Europe and the United States in the mid-19th century.  Concentrating on the period around 1870, we will find that works of art (such as Richard Wagner’s operas, Émile Zola’s novels, and the emergence of Victorian “sensation drama”) combined with neurological research (by Hermann von Helmholtz, Julius Bernstein, and George Miller Beard) to inspire a new conception of consciousness and personhood—a conception we may call the neural subject.

Refreshments will be served.
