Eye Movements and Articulations During a Letter Naming Speed Task (original) (raw)

Despite decades of research conducted to explain the etiology of reading disabilities, it remains unclear why some individuals develop dyslexia whereas others do not. Currently, the most established theory is the phonological deficit hypothesis, which proposes that dyslexia is caused by a deficit in the consolidation and/or retrieval of phonological or sound based codes (Stanovich, 1988). A second factor that has accounted for variability in reading achievement is naming speed (NS) or rapid automatized naming (RAN; Kirby, Georgiou, Martinussen, & Parrila, 2010; Norton & Wolf, 2012). NS tasks measure how quickly and accurately participants can name highly familiar stimuli (e.g., letters) presented in a visual display. Performance on these tasks has been shown to be an independent source of variance in predicting concurrent and future reading ability in poor and developing readers (Compton,
