Abstract

Three experiments addressed whether bidirectional orthographic-phonologic consistency constrains English word recognition and pronunciation. Experiments 1 and 2 investigated the relative time-course of both orthographic-to-phonological (P-O) and phonological-to-orthographic (O-P) consistency by using an identity priming paradigm in naming and lexical decision across three stimulus onset asynchronies (SOAs). Experiment 3 used a semantic categorization task to investigate the degree to which O-P and P-O consistency affect performance in a task that requires access to meaning. Additionally, the composition of filler trials in Experiment 3 was varied to test whether including homophone fillers to enhance reliance on spelling knowledge may modulate any P-O and O-P consistency effects. In each experiment, consistent and inconsistent words were matched on a variety of additional variables to address whether stimulus confounds may account for previous reports of P-O consistency effects. All three experiments revealed sensitivity to O-P consistency while providing mixed support for P-O consistency effects. The results are discussed in terms of a resonance framework and the role of O-P and P-O dynamics in visual word recognition. ^
