Visual Choice Reaction Time Apparatus

This device can be used to measure pure reaction time and simple and discriminative reaction / movement times. You can also use two or more of these units together to demonstrate how reaction time increases as a function of the number of stimulus-response alternatives in a task. Each unit is equipped with four, color stimulus lamps (red, blue, green, and white), one 2800Hz-tone stimulus, and five response keys. 15 feet of cable and a shield at the console separate the operator from the subject.

*An external timing device is required for time measurement, but is not included. See Required Accessories for timer options.
