Inhibition of naming by rhyming primes

Abstract

The priming effects of graphemically similar (e.g., HOSE) and graphemically dissimilar (e.g., ROWS) rhymes on the naming of target words (NOSE) were examined at prime-target stimulus onset asynchronies (SOA) of 36, 70, and 250 msec. A four-field presentation procedure was used of mask-prime-mask-target. The effects of rhyme primes were measured relative to those of nonrhyming control primes (CHEF, DISH) that matched the rhymes in frequency and length and shared no letters in the same positions. At SOAs of 36 and 70 msec, rhyme priming was inhibitory and equal for graphemically similar and graphemically dissimilar rhymes. At SOA = 250 msec, rhyme priming was insignificant with a tendency toward facilitation. The results are discussed in the context of (1) contrasting effects of complete versus partial phonological overlap within a prime-target pair, and (2) the hypothesis that phonological codes stabilize fastest and provide, therefore, the earliest and major constraint on word recognition.
