Research Abstract

Transitory luminance contrast induction (TLCI) is a perceptual phenomenon where regions of subjective high contrast appears in black and white line stimuli. The underlying cause for TLCI remains unknown. In this research project, the physical stimulus parameters for evoking TLCI are experimentally verified, and used to program various models to simulate TLCI. A model of retinal cone dynamics most closely succeeds in simulating TLCI. This led the research towards a theoretical understanding of TLCI : the duration of stimulus changes predicts TLCI and explains why slowly responding cones cause TLCI. TLCI occurs in stimulus regions that are effectively stationary relative to the retina.
