“…Similar results with regard to manual key presses, though in a different paradigm, were found by Cong et al (2010), who showed that blinks are entrained by rhythmic finger tapping. The differences between the modulation of blinks around the two percepts in our study reveal that it is not a mere representation of the motor response.…”

Eye related movements such as blinks and microsaccades are modulated during bistable perceptual tasks, however, the role of such movements in these purely internal perceptual switches is not known. We conducted two experiments involving an ambiguous plaid stimulus, wherein participants had to continuously report their motion percept. To dissociate the effect of blinks and microsaccades from the visual consequences of such eye movements, we added external blanks and microshifts. Our results showed that while blanks facilitated a switch to the coherent motion percept, this was not the case for a switch to component percept. A similar difference was found with respect to blinks. While both types of perceptual switches were preceded by a decrease in blinks, only the switch to coherent percept was followed by an increase in blinks. These blink related findings, which we largely replicated and refined in a second study, indicate distinct internal processes underlying the two perceptual switches. Microsaccade rates, on the other hand, only showed a weak relation with perceptual switches but their direction was modulated by the perceived motion direction. Additionally, our data showed that microsaccades are differently modulated around internal (blinks) and external events (blanks, microshifts), indicating an interaction between different eye related movements. This study shows that eye movements such as blinks and microsaccades are modulated by purely internal perceptual events independent of task related motor or attentional demands. Eye movements therefore can uncover distinct internal perceptual processes that might otherwise be hard to dissociate.

“…This suggests that there also might be a common phenomenon of motor interaction. For example, finger tapping entrains spontaneous blinking [14] as does walking speed [15]. Similarly, other eye movements like (micro-)saccades co-occur with head movements [16,17] and a large saccade size comes with a high blink probability [1].…”

The blink rate increases if a person indulges in a conversation compared to quiet rest. Since various factors were suggested to explain this increase, the present study tested the influence of motor activity, cognitive processes and auditory input on the blink rate but at the same time excluding any social interaction. While the cognitive and auditory factors only showed a minor influence, mere mouth movements during speaking highly increased the blink rate. Even more specific, lip movements, but less jaw movements, are likely responsible for the increase during a conversation. Such purely motor related influences on the blink rate advise caution when using blinks as neurological indicators during patient interviews.

“…In ERP studies, during signal averaging, such a large potential can be a significant artifact that would interfere with waveforms, mainly at anterior scalp sites. If the blink is a reflexive and systematic response to testing design (such as attentional tests that promote expectancy), and it is time locked to the studied events, even the low amplitude VEOG at posterior channels could reveal a significant effect upon the event-related EEG potentials [2,3].…”
