Reversibility of the Necker Cube: VII. Reversal Rate as a Function of Figure-on and Figure-off Durations

Abstract

Reversal rate varied as a function of figure-off duration, holding figure-on duration constant at 300 msec. ( N = 13). There was a rise in reversal rate from 14.0 at 10 msec., then a sharp decline to 4.8 reversals at 800 msec. The rise in reversal rate with increase in figure-on duration from 3.0 at 400 to 18.9 at 4,500 msec., holding figure-off duration constant at 1,000 msec., seemed due primarily to within-exposure, not between-exposure, reversals ( N = 21).
