Abstract
A total of fifty-five subjects were tested in three experimental situations. Blinking was recorded electrically, and related to various features of the three non-visual tasks. A new type of suction electrode was developed for this purpose.
It was found that blink rate fell below the normal resting rate during the learning of a stylus maze, and during a special audio-tracking task. During pauses between each trial, blink rate was above the resting rate.
There was a significant tendency for those subjects who showed the greatest difference in blink rate during the trials and the pauses between each trial to make the fewest errors per run of the stylus maze.
In the audio-tracking task the subjects followed a changing note with a second oscillator. Blink rate was found to be inversely related to the rate of change of the course tone.
