Abstract

The effects of phonological neighborhood density and word frequency in spoken word recognition were examined using distributional analyses of response latencies in auditory lexical decision. A density X frequency interaction was observed in mean latencies; frequency effects were larger for low-density words than for high-density words. Distributional analyses revealed that this interaction was primarily due to differential shifting of the modal portion of the latency distribution between high- and low-frequency words as a function of density. For low-density words, frequency effects were reflected in both distributional shifting and skewing. For high-density words, frequency effects were mediated purely by distributional skewing. The results suggest that word frequency plays a role in early auditory word recognition only when there is relatively little competition between similar-sounding words.
