  Two auditory priming experiments tested whether the final overlap effect relies on syllabic representations. Amount of shared phonetic information and syllabic correspondence between prime and target nonwords were varied orthogonally. In the related conditions, CV.CCVC primes and targets shared the last syllable (e.g. pinclude-viclude) or the last syllable minus one phoneme (e.g. pinclude-viflude); conversely, CVC.CVC primes and targets shared the last syllable (e.g. goltibe-purtibe) or the last syllable plus one phoneme (e.g. goltibe-pultibe). Both experiments required to repeat back the targets, with Experiment 2 including foils. The facilitation induced by related primes increased with the number of shared phonemes, and was by and large independent of syllabic correspondence. There is thus little evidence for pre-lexical syllabic classification.
Phonetic Psycholing. I-2 The effect of mismatching segmental information on the masked onset priming effect (MOPE)

  We report two experiments investigating the masked onset priming effect (MOPE) in reading aloud. More specifically, we tried to answer the question of whether or not mismatching segments in the prime have an inhibitory effect on the MOPE. Dutch native speakers saw four-letter target words preceded by visually masked primes that either consisted of whole words or letters, and either matched or did not match the onset segment of the target. Prime exposure duration was varied between 33 ms and 66 ms to investigate the time course of the obtained effects. Whole-word primes behaved the same as letter primes at the short (33 ms) prime exposure duration, whereas at longer prime exposure (66 ms) effects of mismatching segments present in the whole-word but not in the letter primes led to slower overall naming latencies, suggesting that inhibition from segments beyond the onset needs time to build up.

  Phonetic perception and lexical access is sensitive to acoustic traces of co-articulatory processes in overlapping neighbouring segments. Longer distance coarticulatory effects, though well documented in production studies, have not been examined with regard to their contribution to lexical access Using an eye-tracking paradigm, we examines whether the acoustic reflex of anticipatory lip-rounding and lip-spreading in initial /S/ in German CC and CCC word onset clusters is used to decide between lexical candidates with phonemically identical onsets prior to the contrasting vowel. The results show a clear effect of the pre-vocalic consonant information, but the effect is not symmetrical for rounded and unrounded /S/. Results are discussed in relation to a phonemic vs. a (demi-)syllabic basis of lexical decisions and markedness theory.
