Psych 545 – Color Vision (4 credits)

Spring Quarter 2009

Tues & Thurs 1:30 – 3:20 pm, Guthrie 57

Instructor: Professor Steve Buck

Office: Guthrie 227

Phone/vmail: 543-6789

Email: sbuck@u.washington.edu

Course coverage and target audience

The course will cover both classic and current material related to color perception and psychophysics (including color mixture, color specification and color spaces, chromatic discrimination, and color constancy), peripheral and central neural substrate of color processing, and color-vision deficiencies and genetics. The course is open to all interested graduate students but will be particularly appropriate for those in cognitive neuroscience, behavioral neuroscience, neurobiology and behavior, and cognition/perception.

Readings

In addition to both old and new papers from the primary literature, we'll use a comprehensive text (abbreviated below as SOC), available for purchase online through Barnes & Noble or Amazon:

The Science of Color, 2nd edition, edited by Steven K. Shevell, Elsevier/Optical Society of America, 2003.

Student responsibilities (details to be worked out with class)

- Completion of readings and consistent participation in class.

- 2 oral paper presentations to the class.

- 2 written position papers, 1-2 pages each.

- Individual project to be presented to the class at end of quarter, likely during final exam week. This project is very flexible and could involve work associated with the advanced MatLab class but must be arranged in advance with Steve. Possibilities include:

- Short written summary of 2-3 papers on a topic that extends class coverage.

- Development of a color illusion or demonstration, presented to class

- Development of a solution to a quantitative problem, issue, or application related to color vision.

Projected Class Schedule and Reading Assignments

(This will evolve throughout the quarter, so recheck it often.)
