Description
Summary:The software and hardware to obtain contrast sensitivity functions in a single session with monkeys are described. The versatility of the software allows the program to be used in a variety if sensory systems with minor programming modifications. It will permit absolute or difference threshold measurements with any one of three methods of threshold testing: (1) method of tracking, (2) method of limits, and (3) method of constant stimuli.
