Procedures were developed to evaluate the nature and timing of eye blinks and closures, and these variables were related to alterations in performance. Impaired performance is frequently indexed by alterations in these variables, suggesting that monitoring aspects of oculometric activity, such as the eye blink, may become useful predictors of impaired performance. What may be equally or more important is that such information can be used to alert equipment operators and prevent accidents. The analyses suggest that impaired performance is associated with the occurrence of eye closures, even in tasks where vision is not used, such as making judgments about durations of auditory stimuli. If such closures occur in conjunction with slow eye movements in the horizontal plane, the likelihood of signals being missed is further enhanced. Blinking during the period of stimulus presentation also results in an enhanced likelihood of a signal being missed.
