The elusive nature of early phonological priming effects: are there individual differences?
Lukatela and Turvey (2000) demonstrated a phonological priming effect in the lexical decision task (LDT) with a 14-ms prime and concluded that phonology plays a central role in word meaning activation. In contrast, several other researchers reported that phonological priming is significant only at much longer prime durations (e.g., Ferrand & Grainger, 1994). In two replication attempts (Experiments 1a and 1b), involving a 15-ms prime duration, we found a clear phonological priming effect in one LDT and no evidence of phonological priming in another virtually identical LDT. In Experiment 2, in an attempt to determine whether individual differences may account for the presence or lack of a phonological priming effect, we also tested phonological and perceptual skill. Only participants higher in perceptual and phonological skill showed a phonological priming effect. We conclude that these (and potentially other) variables may have been responsible for previous inconsistent findings of early phonological priming effects.
