We used fluency tasks to investigate lexical organisation in Deaf adults who use British sign language (BSL). The number of responses produced to semantic categories did not differ from reports in spoken languages. However, there was considerable variability in the number of responses across phonological categories, and some signers had difficulty…

The purpose of this study was to examine verbal fluency and verbal short-term memory in 12 adults with Down syndrome (DS) and 12 adults with Intellectual Disability (ID) of unspecified origin, matched for receptive vocabulary and chronological age. Participants' performance was assessed on two conditions of a verbal fluency test, namely, semantic…

This study examines possible semantic interaction in fully fluent adult simultaneous and early second language (L2) bilinguals. Monolingual and bilingual speakers of Spanish and English (n = 144) were tested for their understanding of lexical categories that differed in their two languages. Simultaneous bilinguals came from homes in which Spanish…

Movement artifacts are still considered a problematic issue for imaging research on overt language production. This motion-sensitivity can be overcome by functional near-infrared spectroscopy (fNIRS). In the present study, 50 healthy subjects performed a combined phonemic and semantic overt verbal fluency task while frontal and temporal cortex…

The purpose of this investigation was to test the assumption of asymmetric mapping between words and concepts in bilingual memory as proposed by the Revised Hierarchical Model (RHM, Kroll & Stewart, 1994). Twenty four Spanish-English bilinguals (experiment 1) and twenty English-Spanish bilinguals (experiment 2) were presented with pairs of words,…

An experiment examined whether beginning readers can successfully learn to detect and define homonyms, and whether this ability correlates with vocabulary and/or phonological awareness. First graders received ambiguity instruction involving homonyms in isolation, in riddles, and in text. A control group received reading lessons without a…

Disfluencies can affect language comprehension, but to date, most studies have focused on disfluent pauses such as "er". We investigated whether disfluent repetitions in speech have discernible effects on listeners during language comprehension, and whether repetitions affect the linguistic processing of subsequent words in speech in ways which…

As we age, our ability to select and to produce words changes, yet we know little about the underlying neural substrate of word-finding difficulties in old adults. This study was designed to elucidate changes in specific frontally mediated retrieval processes involved in word-finding difficulties associated with advanced age. We implemented two…

Previous studies have found that proficiency in a second language affects how the meanings of words are accessed. Support for this hypothesis is based on data from explicit memory tasks with bilingual participants who know two languages that are relatively similar phonologically and orthographically (e.g., Dutch-English, French-English). The…

Lexical-semantic access and retrieval was examined in 15 adults diagnosed with schizophrenia and matched controls. This study extends the literature through the inclusion of multiple examinations of lexical-semantic production within the same patient group and through correlating performance on these tasks with various positive and negative…

This analysis of several principles of translation considers relationships between content and meaning, distinctive features and linguistic form, and language and speech. The dichotomies of individual and community speech patterns, situationally determined and independent language usage, and denotative and expressive usage are also examined. The…

With the increasing number of Spanish-English bilingual children in the U.S., both SLPs and researchers must understand speech and language developments in these children--and SLPs also need reliable assessment and intervention approaches for serving bilingual children with language disorders. This comprehensive text is one of the few to offer…
