Perceptual learning in foveal and peripheral contrast discrimination: exploring the effects of stimuli on learning and the effects of learning on spatial vision
… learning (PL), and the effect of PL on discrimination thresholds and crowding in foveal and peripheral vision. Two main configurations of Gabor stimuli were employed in all experiments of the study: ISO (identically oriented target and flankers) and CROSS (orthogonally oriented target …

Visual Discomfort and Visual Function: Colour and Contrast
… who experienced migraine or reading difficulty. Contrast discrimination thresholds were measured at two pedestal contrasts (10% and 50%) in volunteers with migraine with aura (MA), without aura (MO) and controls (C).There was no significant difference in thresholds between groups, although …

Interocular suppression and contrast gain control in human vision
The human visual system combines contrast information from the two eyes to produce a single cyclopean representation of the external world. This task requires both summation of congruent images and inhibition of incongruent images across the eyes. These processes were explored psychophysically …

Visual System Development in People with One Eye: Behaviour and Structural Neural Correlates
… II, I conducted a series of speed and luminance contrast discrimination tasks not yet implemented in this group. Early monocular enucleation results in impaired speed discrimination but intact contrast perception compared to binocular and monocular viewing controls. These findings suggest …

Perception and Production of Geminate Consonants by English Speakers and Kuwaiti Arabic Speakers
… to perceive and reproduce a novel length contrast encoded in new words, the present study aimed to determine the implications of phonemic status of consonant length on perception and production. In a condition where long consonants were derived from singletons and paired with their natural …
