EFFECTS OF MASKED REPETITION PRIMING AND ORTHOGRAPHIC NEIGHBORHOOD INVISUAL RECOGNITION OF WORDS

The role of orthographic neighbourhood (neighorhood size and neighborh ood frequency) in visual-word recognition was analyzed using the maske d repetition priming paradigim. Specifically, we varied stimulus-onset asynchrony (33, 50, and 67 msec.) and type of prime (identical, unrel ated, unprimed) in a lexical-decision task. Analyses show additive eff ects of repetition and stimulus-onset asynchrony. Further, the unrelat ed condition overestimated the repetition effects relative to an unpri med condition. Facilitatory effects of neighborhood size and inhibitor y effects of neighborhood frequency were also found. The results are i nterpreted in terms of current models of visual-word recognition.
