Journal ArticleDOI
Investigating local network interactions underlying first- and second-order processing.
TL;DR: The authors' results indicate that at the smallest inter-element spacing, the perceived reduction in modulation depth is significantly smaller for the second-order than for the first-order stimuli.
Journal ArticleDOI
How are spatial filters used in fovea and parafovea
TL;DR: In this article, the spatial properties of the visual filters were examined for a blur discrimination task for which it had previously been claimed that the best human performance was with pedestal blurs of intermediate magnitude.
Journal ArticleDOI
Scale selection for second-order (non-linear) stereopsis
Laurie M. Wilcox,Robert F. Hess +1 more
TL;DR: This work uses gaussian-enveloped, amplitude-modulated grating patches to determine how the stereoscopic system responds to the presence of two sources of second-order disparity information at different scales when there is no disparity information available via the conventional luminance-based system.
Journal ArticleDOI
The shift in ocular dominance from short-term monocular deprivation exhibits no dependence on duration of deprivation.
TL;DR: Surprisingly, the results show that the dynamics of ocular dominance change after durations of monocular deprivation are of an all-or-none form.
Journal ArticleDOI
The luminance-dependent nature of the visual abnormality in strabismic amblyopia.
Robert F. Hess,E.R. Howell +1 more
TL;DR: These findings together with recent results concerning the relationship between movement and pattern thresholds in amblyopia suggest that the amblyopic abnormality is primarily visual-field specific and does not occur at a photoreceptor level.
