Purpose: Although commonly defined as a speech disorder, stuttering interacts with the language production system in important ways. Our purpose is to summarize research findings on linguistic variables that influence stuttering assessment and treatment. Method and Results: Numerous topics are summarized. First, we review research that has…

Verbal Fluency (VF) task total scores are widely used in language attrition studies, but they do not provide insight into the processes underlying optimal performance. We analyse the efficacy of clustering (subcategories within a category) and switching (shifting between these subcategories) strategies in phonemic (PVF) and semantic (SVF) tasks.…

An aim of research on bilingualism is to understand how the brain adapts to the use of more than one language. Although several important discoveries and insights about the consequences of bilingualism have been generated over the last several decades, concerns about replicability have narrowed the scope of inquiry and discussion to the…

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…

As a basic indicator of verbal ability, verbal fluency refers to the degree of fluency in the use of language to convey information. The different components of working memory play an important role in verbal fluency. The inhibiting control mechanism takes place during L2 production processing in bilinguals, which may affect their verbal fluency…

Individuals with lower proficiency in a second language tend to produce more disfluent speech patterns in the second language. Speech disfluencies refer to interruptions in the forward flow of speech and are distinct from the colloquial use of "fluency," to characterize knowledge of a language. Prior research indicates that some speech…

In vocabulary research there has been a shift from focusing on single words to considering multiword sequences, such as collocations. Despite the general consensus among language researchers that collocation is essential to effective language use in real-world communication, particularly oral communication, language-testing researchers have made…

Can an early learned second language influence speech production after living many years in an exclusively monolingual environment? To address this issue, we investigated the consequences of discontinued early bilingualism in heritage speakers who moved abroad and switched language dominance from the second to the primary learned language. We used…

Numerous studies have shown that bilinguals presented with words in one of their languages spontaneously and automatically activate lexical representations from their other language. However, such effects, found in varied experimental contexts, both in behavioural and psychophysiological investigations, have been essentially limited to the…

This study considers code-switching (CS) and pausing in two sociolinguistically distinct groups in London and Cyprus, bilingual in Greek-Cypriot Dialect (GCD) and English. The characteristics of their speech are examined both in monolingual and bilingual modes (Grosjean, 2001). It was hypothesised that in London Greek-Cypriots, where CS is a…

Bilinguals who are fluent in American Sign Language (ASL) and English often produce "code-blends"--simultaneously articulating a sign and a word while conversing with other ASL-English bilinguals. To investigate the cognitive mechanisms underlying code-blend processing, we compared picture-naming times (Experiment 1) and semantic categorization…

Translation in fluent bilinguals requires comprehension of a stimulus word and subsequent production, or retrieval and articulation, of the response word. Four repetition-priming experiments with Spanish-English bilinguals (N = 274) decomposed these processes using selective facilitation to evaluate their unique priming contributions and factorial…

Purpose: The present study was designed to investigate what linguistic variables best predict bilingual recognition of acoustically degraded sentences and how to identify bilingual individuals who might have more difficulty than their monolingual counterparts on such tasks. Method: Four hundred English speech-perception-in-noise (SPIN) sentences…

Because dual language learners are the fastest--growing segment of the U.S. student population--and the majority speak Spanish as a first language--the new generation of SLPs must have comprehensive knowledge of how to work effectively with bilingual speakers. That's what they'll get in the second edition of this book, an ideal graduate-level text…

It is generally accepted that the presence of a second language (L2) has an impact on the neuronal substrates build up and used for language processing; the influence of the age of L2 exposure, however, is not established. We tested the hypothesis that the age of L2 acquisition has an effect on the cortical representation of a multilingual…
