Signals and Symbols
(language and other processing)
CUNY Graduate Center – Spring 2024

Overview

Language is perhaps the best window we have into cognition. Humans' knowledge of language consists not only in grammatical representation, but in the processes which operate over such representation. Thus, how we are able to convert gradient, continuous, ephemeral perceptual signals into discrete, mental symbols (and vice versa) is of fundamental importance to work toward a fuller understanding the cognitive system of language.

This discussion-based seminar will provide a wide-ranging but in-depth overview of topics in the real-time processing of language, speech, and related perceptual domains. Special attention will be devoted to the use of simple algorithmic models and related experiments in order to explore the specific mechanisms involves in the mental representation and use of language.

Goals and Objectives

  • Gain familiarity with the core questions, debates, and methods common in contemporary research in language processing and psycholinguistics
  • Foster an understanding of the ways in which processing interfaces with the core sub-fields of linguistics (phonology, syntax, etc.). And practice transferring insights and inspirations from one field into adjacent areas.
  • Be able to read and critique the primary literature in processing and psycholinguistics, including the empirical methods and primary data common in the field.
  • Materials

    While there is no official textbook for the course, we will almost exclusively read primary papers from the relevant literature. All readings assigned throughout the term (both required and optional) will be posted to the course schedule/website.

    With the goal of fostering focus, discussion, and the exchange of ideas, the use of screens (laptops, phones, etc.) will not be permitted during class. Any visual aids will be provided via physical materials (e.g. print outs) in class.

    Grading

    As a paper/discussion-centric seminar, the primary component of course grades (50%) will be calculated based on active participation and attendance throughout the term. As part of this effort, each student will lead paper/topic discussion in the course at least once per term (which will count towards the participation grade). This will include preparing a hand-out or discussion-aid to distribute in class.

    Students will also be required to submit a short document (less than a page) each week before class with notes/reflections from the assigned readings (this will constitute 30% of the overall grade).

    Finally, students will write a final term paper (consisting of a research project proposal)—the final paper will make up the remaining 20% of the grade. There will however, be no HWs quizzes or tests assigned throughout the term.

    Accommodations

    The instructor will attempt to provide all reasonable accommodations to students upon request. If you believe you are covered under the Americans With Disabilities Act, please direct accommodations requests to Vice President for Student Affairs Matthew G. Schoengood.

    Attendance

    The course takes place (in person) at the Graduate Center, and students are expected to attend all classes (in person). However, students who have reason to believe they may be contagious for COVID-19 or other infectious diseases should contact the instructor and stay home. Other absences will not be excused, and the instructor reserves the right to tie grades to attendance records.

    Integrity

    In line with the Student Handbook policies on plagiarism, students are expected to complete their own work. The general ethos of the integrity policy is that actions which shortcut the learning process are forbidden while actions which promote learning are encouraged. Studying and discussing notes, papers, and ideas together provides a fruitful avenue for learning and is encouraged. Using a classmate’s solution or text in your submitted notes or having someone else write a portion of your presentation, however, is prohibited because it circumvents the learning process. If you have any questions about what is or is not permissible, please contact your instructor.

    The instructor reserves the right to refer violations to the Academic Integrity Officer.

    Weekly Schedule

    (Please note that this is subject to change.) That said, we'll plan to discuss at least some subset of: Marr's three-levels of analysis for information processing systems (Computational, Algorithmic, and Implementation), continuous vs. discrete representations in speech and vision, perception as a form of ``sampling,'' syntactic parsing/processing, categorical perception, pragmatic processing, the relationship between knowledge and perception (linguistic relativity), the time-course of spoken-word recognition, plasticity in both speech and syntactic processing, word learning, eye-movements in reading and perception; language production, ``frequency effects,'' and the influence of processing on the lexicon.

    If you have a particularly strong interest in a topic not mentioned, just come talk to me and we may be able to add something in.
