Independence of successive inputs and uncorrelated error in visual form perception.

Abstract

A model is presented for determining perceptual independence, defined as when information received on 2 successive form stimulations does not interact and the internal perceptual system error present on the separate stimulations is uncorrelated. 2 experiments are reported where the same stimulus form is presented on different foveal areas with lags between the stimulations of 0-1500 msec. A 3rd experiment presented different forms on the 2 stimulations. All 3 experiments indicate that the successive inputs are independent even when separated by lags of less than 1 msec. The results are interpreted in terms of uncorrelated error or sensitivity at any given moment in time for different elements in the visual perceptual system represented by different foveal areas.
