Changes in blink rate during signal discrimination tasks

Effects of stimulus modality, information processing activity and motor response on the blink rate were examined. In Experiment 1, visual and auditory stimuli were employed. The blink rate peaked just after a stimulus and then progressively decreased until the next stimulus. The changes in the blink rate were similar for both the visual and the auditory stimulus conditions. In Experiment 2, only auditory stimuli were given to examine the effects of discriminative responses and motor responses on the blink rate. The heights of peaks increased as the processing load increased, while the motor responses had no effect on the post-stimulus peaks. Attention level was used to explain the pre-stimulus attenuation, and processing load to the post-stimulus peaks.
