An alternating renewal process describes the buildup of perceptual segregation

Frontiers in Computational Neuroscience, 2015
For some ambiguous scenes perceptual conflict arises between integration and segregation. Initially, all stimulus features seem integrated. Then abruptly, perhaps after a few seconds, a segregated perceptual organization emerges. For example, segregation

Perceptual organization in the tilt illusion

Journal of Vision, 2009
The tilt illusion is a paradigmatic example of contextual influences on perception. We analyze it in terms of a neural population model for the perceptual organization of visual orientation. In turn, this is based on a well-found treatment of natural scene statistics, known as the Gaussian Scale Mixture model.

Time Orientation and Perceptual and Cognitive Organization

, 1966
It was hypothesized that time orientation in children ( N = 44) would be related to degrees of perceptual and cognitive organization. Two measures of time orientation were used, (a) time perception (judgment of intervals) and (b) time span (future time ...
