This study explores a proposition that individuals with dyslexia develop enhanced peripheral vision to process visual-spatial information holistically. Participants included 18 individuals diagnosed with dyslexia and 18 who were not. The experiment used a comparative visual search design consisting of two blocks of 72 trials. Each trial presented two halves of the display each comprising three kinds of shapes in three colours to be compared side-by-side. Participants performed a conjunctive… Expand
How perception and attention participate in reading skill?
In children with reading problems (dyslexia) pictorial visual processing task (fMRI) recruited higher activation in right hemispheric frontal, inferior parietal and anterior cingulate regions, and Visuospatial attention, executive control and visual discrimination (symbolic level) performance contribute to reading.

Investigating the Effects of Modality and Multimedia on the Learning Performance of College Students With Dyslexia
There has been a lack of research on how people with individual differences learn with multimedia materials, in particular with regard to individuals with dyslexia. Dyslexia is a learning disabilityExpand
Popularizing Visuo-Spatial Training for Reading Challenges: A Call to Experts in Support of Language and Non-language-based Cognitive Skills Strengthening
We propose to researchers, educators, and professionals a discussion which contributes to a growing body of research questioning how dyslexia and reading challenges have been researched, diagnosed,Expand


Analysis and models of eye movements in comparative visual search
The analysis of eye movements during task completion yielded diverse results on the underlying perceptive and cognitive processes and provided the basis for two models of the search process. Expand
Dyslexia and Visual Spatial Talents: Are they Connected?
Although it has been claimed that with dyslexia comes visual-spatial gifts, the evidence relevant to this claim is mixed. Whereas individuals with visual-spatial gifts have a disproportionateExpand
Visual-Spatial Attention in Developmental Dyslexia
Results showed that dyslexics had a specific disability in the shifting of attention caused by a peripheral cue at short SOAs, and were also able to maintain attention focused for short periods of time only, presumably not long enough for efficient visual processing. Expand
A Three-Level Model of Comparative Visual Search

A hierarchical model of comparative visual search and its implementation as a computer simulation is presented and it is shown that this Three-Level Model is able to explain about 98% of the empirical data collected in six different experiments. Expand
A Causal Link between Visual Spatial Attention and Reading Acquisition
The present 3 year longitudinal study shows that prereading attentional orienting--assessed by serial search performance and spatial cueing facilitation--captures future reading acquisition skills in grades 1 and 2 after controlling for age, nonverbal IQ, speech-sound processing, and nonalphabetic cross-modal mapping.

Reading disability and enhanced dynamic spatial reasoning: A review of the literature
There is little evidence in support of a spatial advantage in people with dyslexia, and, in fact, the data show that RD samples most often perform worse or equal to non-RD samples. Expand
Visual Learning and the Brain: Implications for Dyslexia
The central and peripheral visual fi elds are struc- turally segregated in the brain and are differentiated by their anatomical and functional characteristics. While the central fi eld appears wellExpand
Developmental dyslexia: The visual attention span deficit hypothesis
It is proposed that a VA span deficit is a likely alternative underlying cognitive deficit in dyslexia, and this hypothesis was assessed in two large samples of French and British dyslexic children whose performance was compared to that of chronological-age matched control children. Expand
Visual-Spatial Strength in Dyslexia Rapid Discrimination of Impossible Figures
It has often been conjectured that visual-spatial talents accompany dyslexia. But do individuals with dyslexia have unusual visual-spatial talents? Individuals with dyslexia were compared to controlsExpand
Dyslexia linked to talent: Global visual-spatial ability
In two investigations, an association between dyslexia and speed of recognition of impossible figures, a global visual-spatial task, is found, suggesting that Dyslexia is associated with a particular type of visual- Spatial talent-enhanced ability to process visual-Spatial information globally (holistically) rather than locally (part by part).
