VISUAL PERCEPTION LABORATORY

Color Vision (Honors Seminar 21962 HON201) Spring 2014

Description: Color makes our world beautiful. One common mistake people tend to make is that they think color is in the light, or color is a characteristics of light. The purpose of this course is to present evidence that color is the consequence of neural processing in our brain and provide students with an understanding of the functional anatomy and neurophysiology of the visual system, and an understanding of how neural activity results in color perception. Students will be exposed with a variety of methods for investigating color vision including molecular biology, psychophysics, electrophysiology, and brain imaging. Students who are interested in visual neuroscience, ophthalmology, visual arts, and engineering will benefit from the course for knowing the fundamental neural basis of color vision.
 
Requirement: This class will heavily involve presentation and discussion over different topics. Students are required to read or watch the materials for each topic before each class and submit a question each week for discussion.

Students will choose to do a presentation or write a short essay (5-10 pages, double space) that reviews a topic related to color vision for final grade.

Course Schedule
 
Topic 1: Demonstration of Color phenomenon (1 hour) Powerpoint Presentation
Week 1: Jan 17, 2014 (Organization, Course Introduction)
Goal: to demonstrate many phenomena related to color vision, including chromatic contrast, assimilation, color filling-in, color constancy, short-term and long-term chromatic adaptation, color afterimage. This demonstration will provide definite evidences that color is not from light, instead, color is a mental experience.
 
Topic 2: The history of color science (1 hour) Powerpoint Presentation
Week 2: Jan 24, 2014

Goal: to introduce the history of scientific research of color vision by outlining the contributions from Newton, Thomas Young, Helmholtz, Maxwell, Hering etc.
Reading: Shevell 2003, Chapter 1, The Origins of Modern Color Science by J. D. Mollon

Topic 3: Light and color specification (2 hours) Powerpoint Presentation

Weeks 3-4: Jan. 31, 2014
Feb. 7, 2014
Goal: to introduce how to measure light, and how light measurements can be used to quantify color based on color matching, or cone spectral sensitivities.

Topic 4: Anatomical and physiological basis for color vision (3 hours) Powerpoint Presentation 1
Weeks 5-7: Feb 14, Feb 21, Feb 28, 2014:
