This course introduces the major topics in the psychology of concepts, focusing on issues of concept representation and use. The first part of the course discusses the main theories of concepts, including the classic view, prototype models, exemplar models, and the knowledge view. We will also spend several weeks discussing computational models that implement these theories, focusing on the neural network and probabilistic modeling traditions. The second part of the course will cover other key topics including taxonomic categories, category-based induction, conceptual development, categorical perception, and conceptual combination. The readings will be drawn from the textbook and classic papers in the field. The course will be in a lecture-discussion format.
Please note that this syllabus is not final and there may be further adjustments.
I am grateful to Greg Murphy for developing this first version of this class and, of course, writing the “The Big Book of Concepts” that we use as our textbook.
We will be using Greg Murphy’s “The Big Book of Concepts” as the textbook for this class. We will also draw original research articles. You can get the book from Amazon, and it also should be available from the NYU bookstore.
- This course is for graduate students in cognitive science and related fields. All students are expected to have previous coursework in psychology.
- Computational modeling has been central to the study of concepts and categories. This course will cover some of the key modeling proposals in the literature, with a stronger focus on modeling than previous versions of the course. I want this to be a positive for everyone interested in the course, and I will not assume you have a lot of experience with computational modeling. I will try to make the material as understandable as possible, even though we will not have time to cover the basics of cognitive modeling. If you have taken “Computational cognitive modeling,” you’re in a great position; if you have had linear algebra and statistics as an undergraduate, you will also be in the a good position to understand the modeling details. If you don’t have either, don’t fret! This course does not require programming or implementing computational models, and I hope you find this aspects of the class interesting regardless of your background.
- Again, computer programming will not be used in this course.
Grading will be based on the response papers (35%) and a final paper (65%). Class participation will be used to decide grades in borderline cases. As we only meet once a week, class attendance is obviously important.
Responses to the reading
Each week you will write a mini-paper (about 4 paragraphs or about 600 words) in which you will critique the week’s readings, discuss an issue raised by it, or propose a new experiment based on it. The main purpose of these responses is to get you to: 1) do the reading on time so we can talk about it, and 2) think about the reading. In the responses, please focus on what issues are most important or interesting and to think about, and what questions are unresolved in the field. Do not give a list of minor questions or flaws. You may skip one weekly response, but any other missed ones will need to be made up. Post your response to the class Piazza page before class (the night before would be preferred). Your responses will be graded on a check-plus, check, or check-minus basis, with most responses receiving a check.
The final paper will be due Monday 12/16. Submit via email with the file name lastname-cc-final.pdf
The final paper should address one of the topics covered in the class in more detail. Alternatively, it could investigate a key topic related to concepts/categories that was not covered in class. To make sure your paper is headed for success, you should write a proposal for your final paper due on Wednesday 11/13 (one half page written). Submit via email with the file name lastname-cc-proposal.pdf (firstname.lastname@example.org). You can also discuss your topic with me during office hours. The paper should include a critical review of the literature, along with theoretical conclusions or suggestions for future research. I would expect papers to be about 12 pages long (double spaced), though the exact length is not as important as the quality of thought the paper reveals. In your paper, you should also be sure to connect with and demonstrate your knowledge of the topics covered in class.
Piazza and course discussion
We will be using Piazza to post the weekly responses to the readings, and for class discussion in general.
The signup link for our Piazza page is available here (https://piazza.com/nyu/fall2019/psychga3405001).
Once signed up, our class Piazza page is available here (https://piazza.com/class/jyuo0qmz3o738c).
Auditing: We have limited room, so please email instructor to see if there are available seats. Priority goes to registered students and then by date of audit request.
