The symbolic systems senior seminar is intended to be a small class, involving student-led discussions. The course generally involves readings that draw on different disciplines which are represented within our core. It is often referred to as the "capstone" experience for symbolic systems majors, because it is ordinarily taken near the end of a student's undergraduate years and because it attempts to put some of the earlier material in the major to use in a group exploration of an advanced topic.
This year's senior seminar will focus on some cross-disciplinary debates about human rationality. At the center of these debates is the work, since the late 1960s, of cognitive psychologists Amos Tversky and Daniel Kahneman ("T&K"), and of others who have done similar research. T&K and other behavioral scientists have produced laboratory evidence supporting the view that higher human cognition departs systematically from what is normatively considered "rational." Their work contrasts human reasoning, judgment, and decision making with accepted principles of logic, probability, and utility.
Their findings have generated aggressive opposition from philosophers, economists, and cognitive scientists who argue for alternative interpretations of the laboratory results. The opponents of the T&K perspective emphasize the broader, practical rationality of the human mind, and they question whether humans are truly irrational.
The class is divided into two sections this quarter. I expect you to attend section each week on the day that you signed up for. In special circumstances, credit for attending the other section during a particular week, as a substitute for attending your own section, will be allowed if you notify me of this in advance. Beginning with the second reading assignment (meetings of April 19 and 24), the Tuesday section will be in synchrony with the preceding Thursday section, rather than with the following Thursday. Cross-attendance credit will depend on attending the section meeting with the same reading assignment as the one you must miss.

Each student is required to help lead a discussion during one of the eight weeks of reading discussion (weeks 2-9). I will interject comments when I think it is appropriate, and serve as an interlocutor along with other students in the class. Emphasis will be on participation by everyone over the course of the quarter. Please contact me if you would like help in preparing to lead a discussion.
The course is S/NC. To receive an "S" a student should miss no more than one session (starting with week 2). Missing a second class requires a 4-5 page summary paper to be prepared, summarizing and reacting to the reading discussed in the missed session.
A course reader will be available at cost from Anita Black, Symbolic Systems Student Services Coordinator (firstname.lastname@example.org, x5-1552), in room 127E of Margaret Jacks Hall, during normal working hours beginning on Friday, April 13. An announcement will be emailed to students in both sections with instructions on how to pay for the reader.
