Contrast polarity differences reduce crowding but do not benefit reading performance in peripheral vision
Previous studies have shown that the spatial extent of crowding in peripheral vision is reduced when a target letter and its flanking letters have opposite contrast polarity. We have examined if this reduction in crowding leads to improved reading performance. We compared the spatial extent of crowding, visual-span profiles (plots of letter-recognition accuracy versus letter position), and read...
متن کاملA New Font, Specifically Designed for Peripheral Vision, Improves Peripheral Letter and Word Recognition, but Not Eye-Mediated Reading Performance
Reading speed is dramatically reduced when readers cannot use their central vision. This is because low visual acuity and crowding negatively impact letter recognition in the periphery. In this study, we designed a new font (referred to as the Eido font) in order to reduce inter-letter similarity and consequently to increase peripheral letter recognition performance. We tested this font by runn...
متن کاملConfiguration specificity of crowding in peripheral vision
Peripheral vision is characterized in part by poor spatial resolution and impaired visual performance, particularly when the object is surrounded by flanking elements, a phenomenon popularly known as "crowding". Crowding scales with eccentricity irrespective of the target size, both in terms of magnitude and spatial extent, which is determined by varying the target-flanker separation. However, ...
متن کاملContrast discrimination in peripheral vision.
Contrast discrimination provides a psychophysical method for studying contrast coding in vision. Our purpose was to compare properties of contrast discrimination in central and peripheral vision. We used forced-choice procedures to measure contrast-increment thresholds as a function of pedestal contrast. Our stimuli were 2-cycle/deg Gaussian-windowed sine-wave grating patches. They were centere...
متن کاملLow Vision Affects the Reading Process Quantitatively But Not Qualitatively
In The Netherlands, children are considered visually impaired, and therefore eligible for institutional support, if their functional vision is less than 3/10 and/or their visual field is less than 30 degrees. If the visual impairment is such that the child is unable to read print and must resort to Braille, he or she is considered to be blind. If, despite a reduced acuity or limited visual fiel...
