We present an MEG study of homonym recognition in reading, identifying effects of a semantic measure of homonym ambiguity. This measure sheds light on two competing theories of lexical access: the "early access" theory, which entails that lexical access occurs at early (pre 200 ms) stages of processing; and the "late access" theory, which…

Humans have knowledge about the properties of their native language at various levels of representation; sound, structure, and meaning computation constitute the core components of any linguistic theory. Although the brain sciences have engaged with representational theories of sound and syntactic structure, the study of the neural bases of…

Argues that the lexical production system takes a compositional approach to processing morphologically complex forms in cases of productive word formation even if the semantics of the word cannot be derived formally from the meaning of its constituents. Evidence is presented from a case of acquired naming impairment in a patient whose ability to…

Introduces this issue of the journal, summarizing current issues in spoken word recognition. Argues a full understanding of the process of lexical access during speech comprehension will depend on resolving several issues: what is the form of the representations used for lexical access; how is phonological information coded in the mental lexicon;…

Compared responses of English-French bilinguals performing semantic categorization and lexical decision tasks using translation-priming stimuli. Using the same stimuli, priming effects were significantly stronger in semantic categorization than in lexical decision, suggesting the translation-priming effect in the former is mediated by semantic…

Atypical vocabulary has been reported as one of the most notable features of the language of adolescents and adults with Williams syndrome (WS), including use of unusual or low frequency words. Two hypotheses were identified regarding the developmental origins of this phenomenon. The "intra-lexicon" hypothesis views the cause in terms of…

Presents a model of high-dimensional context space, the Hyperspace Analogue to Language (HAL), with a series of simulations modelling human empirical results. Proposes that HAL's context space can be used to provide a basic categorization of semantic and grammatical concepts; model certain aspects of morphological ambiguity in verbs; and provide…
