Three Examples from Visual Psychophysics
Three Examples from Visual Psychophysics
We introduce the fundamental components of visual psychophysics by dissecting three example experiments from scaling and sensitivity estimation: estimating perceived intensity of a light patch, measurement of contrast threshold, and measurement of a contrast sensitivity function. The basic elements of visual psychophysics include the selection of what to measure, the method of measurement, visual displays, response collection, and data analysis. This is designed to create a concrete overview that will be the basis of more detailed treatment of these issues later.
