Abstract
Measures of eye activity, such as blink rate and scanning patterns, have been used extensively as psychophysiological indices of mental workload. In a review of measures derived from spontaneous eye activity it is shown that different measures are differentially sensitive to specific aspects of mental workload. A less well known measure of non-spontaneous eye activity, the blink reflex, is also reviewed. Experiments using discrete punctuate stimuli and continuous tasks analogous to real-world systems show that blink reflexes are modulated by attention and that this modulation reflects modality-specific attentional engagement. Future research should examine the utility of the blink reflex according to the desirable properties of sensitivity, diagnosticity, validity, reliability, ease of use, unobtrusiveness, and operator acceptance.

The influence of the experimental set on size, latency and habituation rate of auditory startle reactions in 15 normal volunteers was examined and it was found that the amplitude of the response to the first stimulus was significantly larger in condition 1, and habituated rate was significantly reduced in condition 3, with respect to all other conditions.

The present studies showed that when warning stimuli directed attention instead to weak stimuli presented simultaneously with reflex-eliciting (acoustic) stimuli, cardiac deceleration was still present but reflex magnitude was unchanged or inhibited, however, latency to reflex onset remained facilitated, i.e., latency and magnitude changes were discordant.
