How it measures
"The subject is presented with a large circle composed of small rings. A point travels along the circular path from one ring to the next. Occasionally, however, one ring is skipped and the point jumps to the next ring on the circle. When this occurs, the subject has to respond by pressing the central key on the test subject panel." [1]
