Semantic dementia patients make numerous phoneme migration errors in their immediate serial recall of poorly comprehended words. In this study, similar errors were induced in the word recall of healthy participants by presenting unpredictable mixed lists of words and nonwords. This technique revealed that lexicality, word frequency, imageability,…

Empirical evaluations suggest that use of interactive technologies can reduce the costs of instruction by about one-third. In addition, they can either increase achievement by about one-third while holding time constant or reduce time needed to achieve targeted instructional objectives by about one-third. These technologies can be delivered over…

This article summarizes published research on vocabulary instruction involving students with learning disabilities. Nineteen vocabulary studies that comprised 27 investigations were located. Study interventions gleaned from the review included keyword or mnemonic approaches, cognitive strategy instruction (e.g., semantic features analysis), direct…

A funny thing happened in Cedar Rapids, Iowa, on the way to passing a $46 million school bond during the 2000-01 school year. Through the use of a scientific telephone survey, school district officials determined residents were more than happy to upgrade their school libraries, but were significantly more tight-fisted when it came to improving…

This study was designed to determine a word problem difficulty classification in children with arithmetic learning disabilities (ALD; n = 104) in comparison with typically achieving students (n = 44). We tested variables such as (a) semantic structure (Change, Combine, Compare, and Equalize), (b) operation (subtraction and addition), and (c)…

Instructional design is an integral part of a balanced approach to teaching vocabulary instruction. The goal of this paper is to reflect on several lessons using research-based vocabulary strategies, and to present think-alouds that detail the steps in matching instructional design with those strategies in order to reach the learning outcome.…

Traditional syntactic accounts of verb phrase ellipsis (e.g., ''Jason laughed. Sam did [ ] too.'') categorize as ungrammatical many sentences that language users find acceptable (they ''undergenerate''); semantic accounts overgenerate. We propose that a processing theory, together with a syntactic account, does a better job of describing and…

On the standard, neo-Gricean view, most is semantically lower bounded but may give rise to the meaning "not all" through scalar implicature (Horn (1972)). More recent proposals have claimed that most does not generate a scalar implicature but is semantically both lower and upper bounded (Ariel (2004; in press)). In this article, we investigate the…

We present statistical analyses of the large-scale structure of 3 types of semantic networks: word associations, WordNet, and Roget's Thesaurus. We show that they have a small-world structure, characterized by sparse connectivity, short average path lengths between words, and strong local clustering. In addition, the distributions of the number of…

In the experiments outlined in this article, the authors investigate lexical access processes in language production. In their earlier work, T. Pechmann and D. Zerbst (2002) reported evidence for grammatical category constraints in a picture-word interference task. Although grammatical category information was not activated when subjects produced…

Processing time and memory for sentences were examined as a function of the degree of semantic and causal relatedness between sentences in short narratives. In Experiments 1-2B, semantic and causal relatedness between sentence pairs was independently manipulated. Causal relatedness was assessed through pretesting and semantic relatedness was…

California and Texas mandate 75% to 80% decodable texts for first-grade reading programs, yet these percentages have no empirical base. This study examines the text selections in 6 first-grade programs from the perspective of lexical, semantic, and syntactic features. The composition of text differed across the 6 programs with respect to length,…

Wernicke (1900, as cited in G. H. Eggert, 1977) suggested that semantic knowledge arises from the interaction of perceptual representations of objects and words. The authors present a parallel distributed processing implementation of this theory, in which semantic representations emerge from mechanisms that acquire the mappings between visual…

Uses a quasi-experimental design to compare the social adjustment of 21 children who received the Language for Learning program with those of 24 children enrolled in a comparison school. Finds that the Language for Learning program produced statistically and educationally significant effects, including improvements in social skills and reductions…

Two prototype voice output communication aids were implemented to compare methods of graphic symbol message formulation; one emulated current devices that require syntactical ordering of icons (Default) and the other used semantic frames (iconCHAT). Message constructions of eight typically developing children (7-10 years of age) using both…
