METHODS AND SYSTEMS FOR CALIBRATING STIMULUS-RESPONSE TESTING SYSTEMS

摘要

Methods are provided for calibrating stimulus-response test systems which include a stimulus output device for delivering a stimulus to a subject; and a response input device for receiving a response from the subject. One such method comprises: sensing the stimulus event output by the stimulus output device; recording a calibrator stimulus time associated with detection of the stimulus event in a calibrator separate from the stimulus-response test system; generating a calibrator response after sensing the stimulus event, the calibrator response causing a response input port of the stimulus-response test system to receive a calibrator response signal and to deliver a corresponding calibrator response signal to the test controller; recording a calibrator response time associated with generation of the calibrator response in the calibrator; and determining a latency value associated with the stimulus-response test system based at least in part on a difference between the calibrator response time and the calibrator stimulus time.
