Abstract
A model based on Hartline-Ratliff lateral inhibition (LI) with a time delay shows that LI distributes information across a parallel network, makes output noise lower than input noise, and can simulate psychophysical results in several variations of the metacontrast-masking paradigm. This model answers many of the Weisstein, Ozog, and Szoc (1975) criticisms of a previous version of the Bridgeman lateral inhibitory model: Temporal oscillations in the masking function are eliminated, and differentiation of homophotic from metaphotic activity by the modeled system is shown to be unnecessary. Experimental results consistent with the LI theory but inconsistent with two-channel theories are discussed.
