Learning to identify crowded letters: Does it improve reading speed?
Crowding, the difficulty in identifying a letter embedded in other letters, has been suggested as an explanation for slow reading in peripheral vision. In this study, we asked whether crowding in peripheral vision can be reduced through training on identifying crowded letters, and if so, whether these changes will lead to improved peripheral reading speed. We measured the spatial extent of crow...
متن کاملLinking crowding, visual span, and reading
The visual span is hypothesized to be a sensory bottleneck on reading speed with crowding thought to be the major sensory factor limiting the size of the visual span. This proposed linkage between crowding, visual span, and reading speed is challenged by the finding that training to read crowded letters reduced crowding but did not improve reading speed (Chung, 2007). Here, we examined two prop...
متن کاملSlow Reading in Glaucoma: Is it due to the Shrinking Visual Span in Central Vision?
Purpose Glaucoma is a leading cause of blindness worldwide, characterized by progressive loss of retinal ganglion cells. Patients with bilateral glaucoma read slower than normal cohorts. Here we examined the factors that may underlie slow reading in glaucoma and determined the best predictor of reading speed in glaucoma. Methods A total of 38 subjects participated in this study: 17 patients w...
متن کاملDoes the Visual Attention Span Play a Role in Reading in Arabic?
It is unclear whether the association between the visual attention (VA) span and reading differs across languages. Here we studied this relationship in Arabic, where the use of specific reading strategies depends on the amount of diacritics on words: reading vowelized and nonvowelized Arabic scripts favor sublexical and lexical strategies, respectively. We hypothesized that the size of the VA s...
متن کاملParafoveal magnification: visual acuity does not modulate the perceptual span in reading.
Models of eye guidance in reading rely on the concept of the perceptual span-the amount of information perceived during a single eye fixation, which is considered to be a consequence of visual and attentional constraints. To directly investigate attentional mechanisms underlying the perceptual span, we implemented a new reading paradigm-parafoveal magnification (PM)-that compensates for how vis...
