PURPOSE: A longstanding finding in persons who stutter is that stuttering frequency significantly reduces during choral reading when compared to the solo reading condition. Here, we tested the hypothesis that this decrease in stuttering frequency may be because speech of the normal speaker dictates the speech rhythm of a person who stutters. We used an automated, sensitive acoustic technique-Envelope Modulation Spectral (EMS) analysis- that allowed us to document speech rhythm. METHOD: Seventeen adults who stutter (AWS) read sentences under two conditions: solo reading and choral reading...

PURPOSE: Neurogenic stuttering may be evident after a lesion/dysfunction of wider neural networks. Here we present a case of acquired stuttering as the consequence of immune-mediated encephalitis. METHODS: The case of a 71-year old male who complained about the progressive onset of stuttering and disequilibrium as the consequence of immune-mediated encephalitis, is here reported. Administration of corticosteroid methylprednisolone was useful to recover from impairments...

The current review examines how neurobiological models of language and cognition could shed light on the role of phonological working memory (PWM) in developmental stuttering (DS). Toward that aim, we review Baddeley's influential multicomponent model of PWM and evidence for load-dependent differences between children and adults who stutter and typically fluent speakers in nonword repetition and dual-task paradigms. We suggest that, while nonword repetition and dual-task findings implicate processes related to PWM, it is unclear from behavioral studies alone what mechanisms are involved...

PURPOSE: The study examined the relationship between word-form similarity network (phonological neighborhood) and stuttering occurrence in spontaneous speech in adults. The study asked whether neighborhood characteristics, including the number of neighbors (neighborhood density) and the average word frequency among neighbors (neighborhood frequency), differentiate stuttered from fluent words within spontaneous speech samples, and more specifically, whether neighborhood characteristics facilitate speech fluency in adults who stutter...

PURPOSE: This study is a preliminary attempt to evaluate a new speech fluency measure, the Speech Efficiency Score (SES), in comparison with subjective stuttering severity rating scales and stuttered syllable counts (%SS). METHODS: 277 listeners (92 naïve, 39 speech-language pathology (SLP) students, 124 practicing SLPs, and 22 SLPs who specialize in stuttering) evaluated short recordings of speech on an 11-point scale. Recordings were obtained from 56 adults, of whom 20 were people who stutter, 16 were people who stutter who were using fluency-shaping techniques, and 20 were speakers who do not stutter...

PURPOSE: This study assessed implicit and explicit attitudes toward people who stutter among typically-fluent young adults. METHOD: Participants completed an Implicit Association Test, a measure of implicit attitudes, to assess the strength of association between stuttered vs. fluent speech and positive vs. negative evaluative words. Participants also completed self-report ratings of their attitudes toward people who do and do not stutter (explicit attitude scales)...

PURPOSE: There is evidence of an auditory-perceptual component of stuttering, and backward masking (BM) is a task to explore that role. Prior research reported poorer thresholds for BM tones in a group of children who persisted in stuttering compared to those for a group that did not persist. This study examined BM for adults who stutter for tones and for speech, which tests a phonetic aspect of hearing. METHOD: Eight persons who stutter (PWS) were closely matched with eight controls (PNS) in terms of phonological abilities, verbal span tasks, age, sex and non-verbal intelligence...

PURPOSE: Speech rate convergence has been reported previously as a phenomenon in which one's speech rate is influenced by his/her partner's speech rate. This phenomenon has been demonstrated in artificial settings, and to some extent, in mother-child interactions. The purpose of this study was to explore speech rate adjustment in a quasi-natural adult-adult conversation. METHODS: An A-B-A-B paradigm was used, in which ten adults conversed on a given topic with two experimenters...

Previous work has postulated that a deficit in lexicalization may be an underlying cause of a stuttering disorder (Prins, Main, & Wampler, 1997; Wingate, 1988). This study investigates the time course of lexicalization of nouns and verbs in adults who stutter. A generalized phoneme monitoring (PM) paradigm was used. Adults who stutter (AWS) and typically-fluent peers both showed an expected effect of word class (verbs yielded slower and less accurate monitoring than nouns), as well as phoneme position (word medial/final phonemes yielded slower and less accurate monitoring than word initial phonemes)...

PURPOSE: Speech restructuring treatment can effectively reduce stuttering but the resultant speech may sound unnatural. Martin et al. (1984) speech naturalness scale is widely used by clinicians and researchers, yet little is known about whether including normally fluent speech samples alters the judgement of the naturalness of speech samples of people who stutter, and whether attributes of listeners - specifically training and sex - influence ratings. METHODS: In this study 20 untrained listeners (male and female) and 19 speech language pathology students (female only) rated either the naturalness of 21 speech samples from adults who stutter obtained post-treatment, or the same 21 post-treatment samples randomly mixed with samples of 21 samples from normally fluent speakers matched for age and sex...

Both developmental and acquired stuttering are related to the function of the basal ganglia-thalamocortical loop, which includes the putamen. Here, we present a case of stuttering- and palilalia-like dysfluencies that manifested as an early symptom of multiple system atrophy-parkinsonian type (MSA-P) and bilateral atrophy of the putamen. The patient was a 72-year-old man with no history of developmental stuttering who presented with a stutter for consultation with our otorhinolaryngology department. The patient was diagnosed with MSA-P based on parkinsonism, autonomic dysfunction, and bilateral putaminal atrophy revealed by T2-weighted magnetic resonance imaging...

PURPOSE: Multifactorial explanations of developmental stuttering suggest that difficulties in self-regulation and weak attentional flexibility contribute to persisting stuttering. We tested this prediction by examining whether preschool-age children who stutter (CWS) shift their attention less flexibly than children who do not stutter (CWNS) during a modified version of the Dimension Card Change Sort (DCCS), a reliable measure of attention switching for young children. METHODS: Sixteen CWS (12 males) and 30 children CWNS (11 males) participated in the study...

PURPOSE: This study sought to determine the cortical associates of emotional reactivity and emotion regulation (as indexed by the amplitude of evoked response potentials [ERP]) in young children who do and do not stutter during passive viewing of pleasant, unpleasant and neutral pictures. METHOD: Participants were 17 young children who stutter and 22 young children who do not stutter (between 4 years 0 months to 6 years 11 months). The dependent measures were (1) mean amplitude of late positive potential (LPP, an ERP sensitive to emotional stimuli) during passive (i...

PURPOSE: Social anxiety disorder is a debilitating anxiety disorder associated with significant life impairment. The purpose of the present study is to evaluate overall functioning for adults who stutter with and without a diagnosis of social anxiety disorder. METHOD: Participants were 275 adults who stuttered (18-80 years), including 219 males (79.6%) and 56 females (20.4%), who were enrolled to commence speech treatment for stuttering. Comparisons were made between participants diagnosed with social anxiety disorder (n = 82, 29...

PURPOSE: Lack of social resources to support children who stutter may be due, in part, to the absence of epidemiological data regarding stuttering. This study investigated the proportion of three-year-old children who stutter in a city located in Hokkaido, a northern island of Japan. METHODS: The speech of individual children was assessed as part of a routine, government-conducted health care examination for 3-year-old children. The number of children screened was 2274, or 94...

PURPOSE: The purpose of the present study was to examine relations between children's exogenously triggered response inhibition and stuttering. METHOD: Participants were 18 children who stutter (CWS; mean age = 9;01 years) and 18 children who not stutter (CWNS; mean age = 9;01 years). Participants were matched on age (±3 months) and gender. Response inhibition was assessed by a stop signal task (Verbruggen, Logan, & Stevens, 2008). RESULTS: Results suggest that CWS, compared to CWNS, perform comparable to CWNS in a task where response control is externally triggered...

PURPOSE: The purpose of this study was to examine the executive function (EF) abilities of preschool children who do (CWS) and do not stutter (CWNS) using a parent-report questionnaire and a behavioral task. METHOD: Participants were 75 CWS and 75 CWNS between the ages of 3;0 and 5;11 (years; months). Parents rated their children's EF abilities using the Behavioral Rating Inventory of Executive Function-Preschool Version (BRIEF-P; Gioia, Espy, & Isquith, 2003)...
