N170 visual word specialization on implicit and explicit reading tasks in Spanish speaking adult neoliterates

Laura Sanchez

Adult literacy training is known to be difficult in terms of teaching and maintenance (Abadzi, 2003), perhaps because adults who recently learned to read in their first language have not acquired reading automaticity. This study examines fast word recognition process in neoliterate adults, to evaluate whether they show evidence of perceptual (automatic) distinctions between linguistic (words) and visual (symbol) stimuli. Such a mechanism is thought to be the basis for effortless reading associated with Visual Word Form Area activation that becomes "tuned" to scripts as literacy skills are acquired (McCandliss, Cohen, Dehaene, 2003). High density EEG was recorded from a group of adults who are neoliterate in two reading tasks: (1) a one-back task requiring implicit reading (available only to those who have attained automaticity), and (2) reading verification task, an explicit reading...
