title: Height differences in English dialects: consequences for processing and representation.
abstract: This study examines the role of abstractness during the activation of a lexical representation. Abstractness and conflict are directly modeled in our approach by invoking lexical representations in terms of contrastive phonological features. In two priming experiments with English nouns differing only in vowel height of their stem vowels (e.g.,pin vs. pan), we compare a conflict versus non-conflict situation across English dialects. Based on differences in the vowel height representation, the conflict occurs in American English, but not in New Zealand English. The results show that there is a lack of priming in the conflict, but not in the non-conflict situation. This is taken as evidence for the claim that lexical access is sensitive to conflicts and non-conflicts between acoustic-phonetic and phonological information. We therefore conclude that discrete phonological features are crucial determiners for successful speech perception, which is in line with abstractionist approaches.
