Purpose: Verbal fluency, a task frequently employed in neuropsychological assessment, provides important word productivity data but little information about subjective effort associated with demand monitoring and resource allocation. In two experiments, this study investigated the effects of task variables (semantic vs. phonemic cues; alternating…

Purpose: The study examines the extent of convergence of semantic category members in Spanish-English bilingual children with reference to adults using a semantic fluency task. Method: Thirty-seven children with developmental language disorder (DLD), matched pairwise with 37 typically developing (TD) children in the age range of 7;0-9;11…

Previous research suggests that English monolingual children and adults can use speech disfluencies (e.g., "uh") to predict that a speaker will name a novel object. To understand the origins of this ability, we tested 48 32-month-old children (monolingual English, monolingual French, bilingual English-French; Study 1) and 16 adults…

The present study was designed to examine the underlying brain mechanisms of positive and negative emotional verbal fluency. Three verbal fluency tasks (one non-emotional phonemic task, two emotional tasks: "Joy" and "Fear") were used in this study. The results were analyzed for 35 healthy, Polish-speaking, right-handed adults…

Background: The ability to generate words that follow certain constraints, or verbal fluency, is a sensitive indicator of neurocognitive impairment, and is impacted by a variety of variables. Aims: To investigate the effect of post-stroke aphasia, elicitation category and linguistic variables on verbal fluency performance. Methods &…

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…

Purpose: The cross-modal picture-word interference task is used to examine contextual effects on spoken-word production. Previous work has documented lexical-phonological interference in children with specific language impairment (SLI) when a related distractor (e.g., bell) occurs prior to a picture to be named (e.g., a bed). In the current study,…

This study evaluated the influence of the frequency of reading and writing habits (RWH) associated with education on the performance of adults in brief neuropsychological tasks. A sample of 489 Brazilian subjects, composed of 71% women, aged 21-80 years, with 2-23 years of formal education, was evaluated by the Brazilian Brief Neuropsychological…

This study assessed, in a sample of 98 adult native speakers of Dutch, how their lexical skills and their speaking proficiency varied as a function of their age and level of education and profession (EP). Participants, categorized in terms of their age (18-35, 36-50, and 51-76 years old) and the level of their EP (low versus high), were tested on…

Purpose: Relatively recent research documents that visual choral speech, which represents an externally generated form of synchronous visual speech feedback, significantly enhanced fluency in those who stutter. As a consequence, it was hypothesized that self-generated synchronous and asynchronous visual speech feedback would likewise enhance…

Purpose: The purpose of this study was to investigate whether lexical access in adults who stutter (AWS) differs from that in people who do not stutter. Specifically, the authors examined the role of 3 lexical factors on naming speed, accuracy, and fluency: word frequency, neighborhood density, and neighborhood frequency. If stuttering results…

Examined why adults learning second languages make frequent errors in lexical form. More and less fluent bilinguals in English and Spanish performed a translation recognition task in which they had to decide whether the second of two words was the correct translation of the first. Less fluent participants experienced more interference for…
