COMMUNICATION BY ELECTRICAL STIMULATION OF THE SKIN. VI. THE EFFECT OF INTENSITY LEVEL AND STIMULUS SPACING ON INFORMATION TRANSMITTED VIA STIMULUS DURATION
Abstract
The number of possible absolute identifications of electrical cutaneous stimulus duration was investigated. The amount of information available to the observer, the stimulus-intensity used, stimulus spacing, and experience in the task all significantly affected performance when identifying stimulus-durations. It was concluded that at least four stimulus-durations may be useful for cutaneous signaling where strong intensitylevels are employed, but only three durations should be used with weak intensities or naive observers.
