We studied the reading performance of 340 consecutive, Italian-speaking aphasics in order to evaluate the clinical features of deep dyslexia, the functional impairments underlying semantic paralexias, and their neuranatomical correlates. Semantic paralexias were observed in 9/340 subjects (2.4%). Our data and a review of the literature show that…

In this paper we present an unsupervised neural network model of bilingual lexical development and interaction. We focus on how the representational structures of the bilingual lexicons can emerge, develop, and interact with each other as a function of the learning history. The results show that: (1) distinct representations for the two lexicons…

This study examined the effects of the age of acquisition (AOA) and semantic transparency on the reading aloud ability of a Chinese dyslexic individual, TWT, who relied on the semantic pathway to name characters. Both AOA and semantic transparency significantly predicted naming accuracy and distinguished the occurrence of correct responses and…

This experimental study offers empirical evidence of the effect of the computer-mediated environment on the linguistic output of low proficiency learners. The subjects were 32 female undergraduates with high and low proficiency in ESL. A within-subject repeated measures concurrent nested QUAN-qual (Creswell, 2003) mixed methods approach was used.…

Given the well-documented understanding that stuttering behavior elicits stereotypically negative responses from listeners, two experiments explored the equivocal results of earlier investigations concerning the potential for self-acknowledgment and modification of stuttering to elicit positive responses from naive (unfamiliar with stuttering)…

There is now a large body of evidence suggesting that color and photographic detail exert an effect on recognition of visually presented familiar objects. However, an unresolved issue is whether these factors act at the visual, the semantic or lexical level of the recognition process. In the present study, we investigated this issue by having…

This study was designed to enhance our understanding of the changing relationship between low- and high-level writing processes in the course of development. A dual description of writing processes was undertaken, based on (a) the respective time courses of these processes, as assessed by an analysis of eye and pen movements, and (b) the semantic…

This study analyzes the acquisition of relative clauses in Japanese to determine the semantic and functional characteristics of children's relative clauses in spontaneous speech. Longitudinal data from five Japanese children are analyzed and compared with English data (Diessel & Tomasello, 2000). The results show that the relative clauses produced…

Two experiments investigated preschoolers' interference control in variants of the day-night task. The day-night task involves instructing children across 16 trials to say the word "day" when viewing a card depicting a nighttime sky and to say "night" when shown a picture of the daytime sky. The purpose of the experiments was to investigate…

Purpose: Our previous work on manipulating typicality of category exemplars during treatment of naming deficits has shown that training atypical examples generalizes to untrained typical examples but not vice versa. In contrast to natural categories that consist of fuzzy boundaries, well-defined categories (e.g., "shapes") have rigid…

This paper provides a typological interpretation of differences between Chinese and English in grammatical metaphor (GM), a phenomenon arising from the interaction of semantics and lexicogrammar and extending the meaning potential in a language. This paper first describes typological features in Chinese and English in terms of the three variables…

A variant of the picture--word interference paradigm was used in three experiments to investigate the horizontal information flow of semantic and phonological information between nouns in spoken Mandarin Chinese sentences. Experiment 1 demonstrated that there is a semantic interference effect when the word in the second phrase (N3) and the first…

The English plural is about the "number" of "individuals" in a "set" of "like kinds." Two-year-old children use the plural but do not do so in all obligatory contexts. The present report asks whether the limitations on their production of the plural are related to aspects of meaning. In two Experiments plural productions were elicited from…

This paper investigates whether the semantic and phonological levels in speech production are specific to spoken languages or universal across modalities. We examined semantic and phonological effects during Catalan Signed Language (LSC: Llengua de Signes Catalana) production using an adaptation of the picture-word interference task: native and…

The authors investigated semantic neighborhood density effects on visual word processing to examine the dynamics of activation and competition among semantic representations. Experiment 1 validated feature-based semantic representations as a basis for computing semantic neighborhood density and suggested that near and distant neighbors have…
