Phonological competition theory states that competition among discrepant segments of similar words leads to inhibition of high-frequency word-naming responses in form-related priming tasks. If segments are selected sequentially, competition should be greater for begin-related pairs (storage-story), in which discrepant segments are late in the words, than(More)
Levelt et al. (1991) argued that modular semantic and phonological stage theories of lexical access in language production are to be preferred over interactive spreading-activation theories (e.g., Dell, 1986). As evidence, they show no mediated semantic-phonological priming during picture naming: Retrieval of sheep primes goat, but the activation of goat is(More)
Manipulating the semantic relatedness of noun and verb targets in contexts where they are grammatically appropriate or inappropriate allows for simultaneous examination of syntactic and semantic context effects. A lexical-decision experiment showed both a syntactic context effect and a semantic relatedness effect that was stronger in syntactically(More)
In Mandarin Chinese, speakers benefit from fore-knowledge of what the first syllable but not of what the first phonemic segment of a disyllabic word will be (Chen, Chen, & Dell, 2002), contrasting with findings in English, Dutch, and other Indo-European languages, and challenging the generality of current theories of word production. In this article, we(More)
Context effects on lexical decision were analyzed by manipulating lexical relatedness and syntactic connectedness. Related and unrelated word pairs were embedded in syntactic (e.g., "the author of this book/floor") and in scrambled (e.g., "the author the and book/floor") phrases. The sequences were presented serially and subjects made lexical decisions to(More)
This paper studies the reliability and validity of naturalistic speech errors as a tool for language production research. Possible biases when collecting naturalistic speech errors are identified and specific predictions derived. These patterns are then contrasted with published reports from Germanic languages (English, German and Dutch) and one Romance(More)
Theories of language production are monolingual but the world is multilingual. In the domain of word-form encoding, it is clear that languages rely differentially on different phonological units, challenging the generality of the monolingual theories. To address this, we propose the proximate units principle, which holds that the initial selection of(More)
Semantic interference in word retrieval has been observed for both well-learned and ad hoc inter-item relations. We tested whether such semantic interference extends to the blocked cyclic naming of racially homogeneous vs. heterogeneous faces. No information except arbitrarily assigned names was provided for novel faces. Yet we observed interference in(More)
