Lexical competition in phonological priming: Assessing the role of phonological match and mismatch lengths between primes and targets

subject

description

In five experiments, we examined lexical competition effects using the phonological priming paradigm in a shadowing task. Experiments 1A and 1B replicate and extend Slowiaczek and Hamburger's (1992) observation that inhibitory effects occur when the prime and the target share the first three phonemes (e.g., /bRiz/-/bRik/) but not when they share the first two phonemes (e.g., /bRepsilonz/-/bRik/). This observation suggests that lexical competition depends on the length of the phonological match between the prime and the target. However, Experiment 2 revealed that an overlap of two phonemes is sufficient to cause an inhibitory effect provided that the primes mismatched the targets only on the last phoneme (e.g., /b[symbol: see text]l/-/b[symbol: see text]t/). Conversely, with a three-phoneme overlap, no inhibition was observed in Experiment 3 when the primes mismatched the targets on the last two phonemes (e.g., /bagepsilont/-/baga3/). In Experiment 4, an inhibitory effect was again observed when the primes mismatched the targets on the last phoneme but not when they mismatched the targets on the last two phonemes when the time between the offset of overlapping segments in the primes and the onset of overlapping segments in the targets was controlled for. The data thus indicate that what essentially determines prime-target competition effects in word-form priming is the number of mismatching phonemes.
