The traditional view of the lexical system stipulates word-specific representations and separate pathways for regular and exception words, while an alternative approach views lexical knowledge as developing from general principles applied to mappings among distributed representations of written and spoken words and their meanings. In this study,…

In three experiments we investigated the locus of the frequency effect in lexical access and the mechanism of gender feature selection. In Experiment 1, participants were asked to produce gender-marked verb plus pronominal clitic utterances in Italian (e.g., "portalo" (bring it [masculine]) in response to a written verb and pictured object. We…

Event-related potentials were measured as subjects read sentences presented word by word. A small N400 and a robust P600 effect were elicited by verbs that assigned the thematic role of Agent to their preceding noun-phrase argument when this argument was inanimate in nature. The amplitude of the P600, but not the N400, was modulated by the…

Investigated the relationship between syntactic and semantic processing using a word-by-word reading paradigm and a cross-modal integration paradigm. The study evaluated the experimental results with regard to serial autonomous models, strongly and weakly interactive models, and a hybrid model proposed here. (92 references) (Author/CK)

Discusses "cued shadowing," during which subjects listen to pairs of words or sentences and repeat a target word signalled by a cue. Rapid semantic and grammatical priming effects have been observed with this technique, both with word and sentence contexts and at different positions within sentence contexts, in normal children and adults, and in…

Describes the different priming procedures and experimental variables used for gaining access to the nature of the lexical representation of morphological information and summarizes the experimental data collected across different languages. Notes that responses to a target word in auditory word recognition tasks can be facilitated when the word…

Evaluated the distinctiveness, independence, and relative time courses of the event-related brain potentials (ERPs) elicited by syntactically and semantically anomalous words. ERPs were recorded while subjects read sentences, some of which contained a selectional restriction violation, a verb-tense violation, or a doubly anomalous word that…

Investigated the time course of activation of the mental representations of word meanings in a series of three cross-modal priming experiments. The study interprets the data with respect to both localist and distributed implementations of the cohort model. Results indicate that if early competition among simultaneously activated meanings exists,…

Examines semantic errors produced by normal and aphasic speakers on a picture naming test for their phonological similarity to the targets they replace. A second study examines phonological relationships within sets of semantically related words and shows there is no tendency for these words to share phonological characteristics. (35 references)…

Examined how skilled adult readers assign meaning to sentences. Of particular interest were sentences containing "experiencer" verbs, which describe states or emotions rather than actions. Subjects were university students in Australia. Test items were semantically implausible sentences. (Author/VWL)

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…

Demonstrates how the definition of "simple attachment" and "tree lowering," operations related to the grammatical composition operations of "substitution" and "adjunction" in the Tree Adjoining Grammar formalism, yields a parser more constrained than previous description theory based models. The article…

Notes that in a typical word monitoring paradigm, subjects monitor ongoing language input for a pre-designated target word and that independent variables include the nature and position of the target word and the context in which it is embedded. Also notes that forms of this task are suitable for studies with young children and with individuals…

Reviews some history of how lexical representations have acquired an important role in sentence processing research. Discusses relevant issues, including the importance of timecourse information in theorizing; the importance of frequency information in theories of sentence processing; and the question of the grain of frequency information. (42…

Proposes an alternative account of the child's learning of nouns and adjectives that relies on properties of the semantic categories to be learned and of the word-learning task itself. In five experiments, a simple connectionist network was trained to label input objects in particular contexts; the network learned categories resembling nouns…
