Equating discriminability of subjective contours across the visual field requires two scaling factors
… describes the ratio of peripheral to foveal stimulus size required to equate performance. Tasks and visual brain regions have different IMFs. It is argued in this thesis that IMFs may average out when a methodology insensitive to the presence of multiple IMFs is used. This fact is …

Fundamentals of spatial vision in the barn owl (Tyto alba pratincola) : ocular aberrations, grating acuity, contrast sensitivity, and vernier acuity
… seem to be similarly influenced by the choice of stimulus configuration and viewing conditions as it is the case in human observers. Specifically, vernier thresholds were worse in a crowded stimulus situation, and better under binocular viewing conditions. The latter is referred to as binocular …

Perceptual learning in foveal and peripheral contrast discrimination: exploring the effects of stimuli on learning and the effects of learning on spatial vision
… 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 and flankers). Crowding was investigated in both orientation discrimination and …

Sonorous breathing: a theoretical and treatment outcome study
… and mouth breathing causes snoring. Altering the stimulus configuration which elicits the respiration response was predicted to be effective in reducing snoring. An electrically-induced muscle contraction in the throat was utilized to replace the low muscle tonus with a high muscle tension …
