The two-interval stimulus. The first interval (adapter) lasted 1.5 s during which the subject was moved 15 cm at a peak velocity of 20 cm/s. After the adapter, there was an inter-stimulus interval (ISI) during which no motion occurred. In this example, the ISI was 1 s, but it was varied between 0.5 and 3.0 s. The ISI was followed by a second-interval (test) stimulus lasting 0.5 s. The amplitude of the 0.5-s test stimulus was varied by the staircase. The largest test stimulus (solid line) is shown with a smaller test stimulus in the opposite direction (dashed). a: Acceleration, b: velocity, c: position
