[HTML][HTML] Investigation of interocular blur suppression using luminance-modulated and contrast-modulated noise stimuli

AS Chima, MA Formankiewicz, SJ Waugh - Journal of Vision, 2015 - tvst.arvojournals.org

suppression. The present study measured interocular suppression depth and extent in …

[HTML][HTML] Interocular suppression patterns in binocularly abnormal observers using luminance-and contrast-modulated noise stimuli

AS Chima, MA Formankiewicz, SJ Waugh - Journal of Vision, 2016 - iovs.arvojournals.org
In binocular viewing, images presented to the amblyopic eye are suppressed in the cortex to
prevent confusion or diplopia. The present study measures depth and extent of interocular …

[HTML][HTML] Very few exclusive percepts for contrast-modulated stimuli during binocular rivalry

J Skerswetat, MA Formankiewicz, SJ Waugh - Vision Research, 2016 - Elsevier

insight into their locus of processing. Two orthogonally orientated gratings were presented …

Foveal visual acuity is worse and shows stronger contour interaction effects for contrast-modulated than luminance-modulated Cs

MI Hairol, MA Formankiewicz, SJ Waugh - Visual Neuroscience, 2013 - cambridge.org
Contrast-modulated (CM) stimuli are processed by spatial mechanisms that operate at larger
spatial scales than those processing luminance-modulated (LM) stimuli and may be more …

[HTML][HTML] Visual acuity measured with luminance-modulated and contrast-modulated noise letter stimuli in young adults and adults above 50 years old

PJ Woi, S Kaur, SJ Waugh, MI Hairol - F1000Research, 2016 - ncbi.nlm.nih.gov

blobs in the presence of fixed modulation, laterally placed noise blobs (separations of 0–6°) …

Considerations of modified vision and crowding tests, for improved detection of amblyopia

L Haine - 2023 - aru.figshare.com
Amblyopia is a neurodevelopmental disorder characterised by deficits of visual acuity. It
demonstrates greater sensitivity to visual crowding; the phenomena whereby accurate …

Contrast-modulated stimuli produce more superimposition and predominate perception when competing with comparable luminance-modulated stimuli during …

J Skerswetat, MA Formankiewicz, SJ Waugh - Scientific Reports, 2020 - nature.com
