Blinks can take several forms. Besides the blinks that wash the eye, there are those associated with unexpected circumstances (such as loud noises), as well as the voluntary flaps of the eyelids that may express anger or incredulity. Another type, the spontaneous eye blink, is neither voluntary nor reflexive. Most blinks are spontaneous.
Mere eye-rinsing requires a blink no more than once a minute; yet most people blink around 15 times a minute. Why do we blink so frequently? Apparently there is a direct relationship between spontaneous blinking and the mind. Scientists can now discern how the frequency and duration of blinks vary according to whether a person is alert, bored, anxious or concentrating.
Studies show first of all that we blink less when we are most alert. A person reading a novel blinks about six times a minute; someone engaged in conversation blinks more than twice as often. Automobile drivers blink less when negotiating distracting city streets than when cruising down highways.
Researchers have learned that the rate and duration of our blinks vary according to the tasks we perform. People engaged in visual activities like drawing blink less frequently; fatigued individual blink more often than when they are rested. We blink more if upset.
Anxiety also increases the number of blinks. Notice helicopter pilots blink more often than instructors, and witnesses under cross-examination blink more frequently than those facing friendly lawyers.
This connection between blinking and apprehension explains why television newscasters are instructed to blink normally, in order to appear calm and controlled and, thus, unflappable before the cameras. This also applies to politicians. Newsweek reports that when neuro-psychologist Joe Tecce monitored Michael Dukakis and Geoge Bush during their debate last October, he concluded that the Massachusetts governor was more nervous. Dukakis averaged 75 blinks per minute (92 when asked if he’d raise taxes), Bush 67.
