Developmental changes in children's verbal fluency were explored in this study. One hundred and forty children aged from 7 to 16 completed four verbal fluency tasks, each with a different the production criterion (letter, sound, semantic, and free). The age differences were analyzed both in terms of number of words produced, and clustering,…

Idiom comprehension was assessed in 10 aphasic patients with semantic deficits by means of a string-to-picture matching task. Patients were also submitted to an oral explanation of the same idioms, and to a word comprehension task. The stimuli of this last task were the words following the verb in the idioms. Idiom comprehension was severely…

Two types of experiments investigate the visual on-line and off-line processing of German ver-verbs (e.g., verbittern "to embitte"). In Experiments 1 and 2 (morphological priming), latency patterns revealed the existence of facilitation effects for the morphological conditions (BITTER-VERBITTERN and BITTERN-VERBITTERN) as compared to the neutral…

We report a series of neural network models of semantic processing of single English words in the left and the right hemispheres of the brain. We implement the foveal splitting of the visual field and assess the influence of this splitting on a mapping from orthography to semantic representations in single word reading. The models were trained on…

A current area of controversy within the literature on visual word recognition concerns the extent to which semantic information influences the computation of phonology. Experiment 1 revealed that both the imageability effect and the ambiguity advantage seen in the speeded naming task are confined to words with atypical mappings between spelling…

Four experiments are reported exploring whether distractor pictures activate their phonological properties in the course of speech production. In Experiment 1, participants were presented with two pictures and were asked to name one while ignoring the other. Distractor pictures were phonologically related, semantically related or unrelated to the…

An account was tested of the development of the interplay between automatic processes and cognitive resources in reading. According to compensatory-encoding theory, with advancing skill, readers increasingly keep automatic processes from faltering and provide timely, accurate data to working memory by pausing, looking back, rereading, and…

Semantic priming refers to a reduction in the reaction time to identify or make a judgment about a stimulus that has been immediately preceded by a semantically related word or picture and is thought to result from a partial overlap in the semantic associates of the two words. A semantic priming lexical decision task using spoken words was…

D. C. Plaut and J. R. Booth presented a parallel distributed processing model that purports to simulate human lexical decision performance. This model (and D. C. Plaut, 1995) offers a single mechanism account of the pattern of factor effects on reaction time (RT) between semantic priming, word frequency, and stimulus quality without requiring a…

The production of cohesive discourse, especially maintained reference, poses problems for early second language L2 speakers. This paper considers a communicative account of overexplicit L2 discourse by focusing on the interdependence between spoken and gestural cohesion, the latter being expressed by anchoring of referents in gesture space.…

A study of the organization of the bilingual's mental lexicon is reported. First, three major hypotheses are examined: (1) Shared Semantic Store or interdependence hypothesis, suggesting a single conceptual memory system; (2) Separate Semantic Store hypothesis, that words and meanings are stored separately; and (3) Shared-&-Separate Semantic…

In a discussion of second language vocabulary teaching and learning, the premise is that vocabulary development from context should not be used as a teaching strategy exclusive of other methods, such as direct teaching through word pair translation; rather, these approaches should be seen as complementing each other. Several arguments in favor of…

A revisionist account of the development of ideas about semantics in modern theories of language is presented, focusing on the rift between Noam Chomsky and Generative Semanticists about the concept of deep structure, or the role of meaning in grammar. The discussion re-appraises the paradigm that has dominated American linguistics since the…

Concepts in cognitive psychology are applied to the language used in military situations, and a sentence classification system for use in analyzing military language is outlined. The system is designed to be used, in part, in conjunction with a natural language query system that allows a user to access a database. The discussion of military…

Automatic processing of word meaning by bilingual children was studied in a picture/word interference task. Thirty elementary and junior high students, fluent in French and English, named pictures as rapidly as possible while attempting to ignore distractor words printed inside the pictures' borders. The printed distractors interfered with naming…
