Abstract
Distorting the word superiority effect with intraword spacing was used to investigate the processing difference in single-word reading for dyslexics and controls. Perfetti’s Reading model suggests that dyslexics would have reduced processing capacity with intraword spacing. Results from a Covid-modified experimental protocol generally did not support the hypothesis. There was poor differentiation between groups in the word capacity coefficient. Response time by itself was also not informative. However, dyslexics had reduced accuracy in distractor identification across intraword spacings due to the lack of retention in phonological working memory or attention in central executive deficit (Alt, Fox, Levy, et al., 2022; Gray, Green, Alt, et al., 2017) as matching targets was not an issue, only confirmation of an update was problematic. In target identification, early responses and later responses were predictive of WIAT III Pseudoword (phonetic processing) and WAIS-IV Symbol Search (visuospatial matching task). These preliminary results motivate further research regarding word processing differences in dyslexic and controls.
