Visual Attention Span

The number of distinct visual elements that can be processed simultaneously in a single glance. Visual attention span is a cognitive capacity linked to reading ability — when reading, the eyes fixate on a word and the visual attention span determines how many letters can be identified in parallel during that fixation. Research has shown that reduced visual attention span is associated with reading difficulties in both children with and without dyslexia, independent of phonological deficits. Training visual attention through tasks like visual search (finding a target among distractors) and motion object tracking has been explored as an intervention for dyslexia, based on evidence that improving visual attention processing can support reading development. This represents a complementary approach to phonological training, addressing the heterogeneity of cognitive profiles in people with dyslexia.
