The evidence of increases in blink rate as a function of time on task is compelling. However, variables other than time on task also affect blink rate. These variables range from perceptual demandingness of the task to cognitive variables.

WebBlink rate can be measured incidentally with eye-movement (since the position of the eye is obscured when the controller blinks), or with EEG, where blinking creates artefacts, which are normally detected and discounted in EEG analysis. Special electrodes are often applied in EEG work to detect eye movement, and can incidentally record blinks. WebNormally, relaxed adult humans blink at a rate between 15 to 20 times a minute. There are some situations where a person’s habitual blink rate will be different from the standard rate. These would include wearing contact lenses, allergies, some foreign particle in the eye, and diseases such as schizophrenia (faster blink rate) or Parkinson’s disease (slower blink …
