Exchange of disfluency with age from function to content words in Brazilian Portuguese speakers who do and do not stutter

The purpose of this study was to investigate the exchange of disfluencies from function words to content words with age in Brazilian Portuguese speakers who do and do not stutter. Ninety stuttering individuals and 90 controls, native speakers of Brazilian Portuguese, were divided into three age groups (children, adolescents and adults). The study method involved analyzing the occurrence of stuttering on content and function words based on spontaneous speech samples. Results indicated that children tend to be more disfluent on function words. With the increase in age, teenagers and adults who stutter presented a higher number of disfluencies on content words. These findings support the current literature, indicating that with the aging process, there is an exchange of disfluencies from function to content words. This shift in the disfluency pattern may account for a more advanced type of stuttering. The study also demonstrated that disfluencies in Portuguese speakers follow the same pattern of shifting from function to content words with age as for English speakers.

Tratamento farmacológico da gagueira: evidências e controvérsias

OBJETIVO: Este artigo tem por objetivo analisar a situação do tratamento farmacológico da gagueira, mostrando a eficácia de diferentes abordagens baseadas em drogas psiquiátricas, além de evidenciar a utilização de outros fármacos no tratamento dessa enfermidade. MÉTODOS: Revisão de literatura em base de dados Medline, utilizando os termos stuttering treatment, disfluency, disfluency treatments, botulinum toxin and stuttering treatment, botulinum toxin and disfluency treatment. RESULTADOS: Foram encontrados estudos envolvendo as seguintes drogas: citalopram + clomipramina, paroxetina, olanzapina, citalopram + alprazolam, pimozida, risperidona, tiaprida, clomipramina e desipramina, levetiracetam, divalproato de sódio, clonidina e betanecol, além de ensaios clínicos com a utilização de toxina botulínica tipo A e anestésicos. Os estudos envolvendo citalopram + clomipramina, paroxetina, olanzapina, citalopram + alprazolam, risperidona, clomipramina e desipramina, levetiracetam, divalproato de sódio, lidocaína e toxina botulínica tipo A demonstraram resultados positivos. A maioria das pesquisas relativas ao tratamento farmacológico da gagueira se restringe a estudos de caso e ensaios clínicos com pequenas amostras. CONCLUSÃO: Não existem evidências suficientes que justifiquem a utilização de um tratamento específico para a gagueira. Os estudos apresentados indicam a necessidade da realização de mais ensaios clínicos duplo-cegos e controlados com placebo envolvendo amostras maiores.

The metacognitive cue of fluency on taste perception

The relative ease tha t a person experiences while performing cognitive operations, namely processing fluency, affects a broad range of judgments such as product evaluations. For example, an increase in fluency through repeated exposure to product packages enhances attitude toward the brand (Janiszewski 1993). This thesis examined the effect of fluency on taste perception and demonstrated where the fluency created an advantage or disfluency created a disadvantage for taste evaluations. Experiment 1 examined the effect of perceptual fluency on taste perception. It was found that perceptual disfluency derived from r eading the labels (i.e., font) lowered taste evaluations only when it was experienced be for the sensory experience. Experiment 2 examined the effect of linguistic fluency (i.e., pronunciation) on taste perception. However there was no evidence for the effect of linguistic fluency on taste perception. Thus, it is concluded that either the effect size of linguistic fluency is lower than perceptual fluency, or participants discounted their linguistic fluency experience because they realized that the brand names used in Experiment 2 were not real brand names. To sum up, it was found that perceptual disfluency created by presenting a difficult to read product-related information created a disadvantage for taste perception compared to when no information was presented. Therefore, this thesis provides the first evidence for the effect of the metacognitive cue of fluency on sensory evaluations.

Hesitations and repair in German

The occurrence of pauses and hesitations in spontaneous speech has been shown to occur systematically, for example, "between sentences, after discourse markers and conjunctions and before accented content words." (Hansson [15]) This is certainly plausible in English, where pauses and hesitations can and often do occur before content words such as nominals, for example, "uh, there's a … man." (Chafe [8]) However, if hesitations are, in fact, evidence of "deciding what to talk about next," (Chafe [8]) then the complex grammatical system of German should render this pausing position precarious, since pre-modifiers must account for the gender of the nominals they modify.In this paper, I present data to test the hypothesis that pre-nominal hesitation patterns in German are dissimilar to those in English. Hesitations in German will be shown, in fact, to occur within noun phrase units. Nevertheless, native speakers most often succeed in supplying a nominal which conforms to the gender indicated by the determiner or pre-modifier. Corrections, or repairs, of infelicitous pre-modifiers indicate that the speaker was unable to supply a nominal of the same gender which the choice of pre-modifier had committed him/her to. The frequency of such repairs is shown to vary according to task, with fewest repairs occurring in elicited speech which allows for linguistic freedom and therefore is most like spontaneous speech. The data sets indicate that among German native speakers, hesitations occurring before noun phrase units (pre-NPU hesitations) indicate deliberation of what to say, while hesitations within or before the head of the noun phrase (pre-NPH hesitations) indicate deliberation of how to say what has already been decided (cf. Chafe [8]).

A study of familial stuttering

Here we study 13 families with stuttering. of the 13 families, 9 were persistent stutterers and 4 were recovered stutterers. In the 9 families with persistent stuttering, 24 were male and 10 were females. of the 4 families with recovered stutterers, 17 were male and 3 were female. of the 17 males, 12 were persistent stutterers and 5 recovered after adolescence. All females were recovered stutterers. We conclude with a short discussion of recent molecular Studies. (c) 2006 Wiley-Liss, Inc.

Prevalence of risk factors for stuttering among boys: analytical cross-sectional study

CONTEXTO E OBJETIVO:Há poucos estudos sobre os fatores de risco para os subgrupos de gagueira. O objetivo deste estudo foi caracterizar os fatores de risco para a gagueira desenvolvimental familial em meninos que gaguejam e que não gaguejam como tipologia das disfluências, fatores qualitativos e comunicativos associados, estresse físico e emocional, atitude familiar e reação pessoal.TIPO DE ESTUDO E LOCAL:Estudo transversal analítico com um grupo controle, realizado no Laboratório de Estudo da Fluência, que faz parte do Departamento de Fonoaudiologia de uma universidade pública.MÉTODOS:Pais de 40 meninos com e sem gagueira pareados por idade fizeram parte do estudo. Os participantes foram divididos em dois grupos: crianças com gagueira e crianças sem gagueira, com idades entre 6 anos 0 meses e 11 anos 11 meses Inicialmente todos os participantes foram submetidos a uma avaliação de fluência e depois os dados foram coletados por meio do Protocolo de Risco para a Gagueira do Desenvolvimento.RESULTADOS:Não foi observada diferença nos fatores de estresse físicos e reações pessoais entre os grupos. As atitudes inadequadas familiares foram apresentadas por 95% das crianças com gagueira e 30% das crianças sem gagueira. Quatro fatores de risco analisados não ocorreram nas crianças sem gagueira, a saber, disfluências gagas, fatores qualitativos, estresse físico e emocional.CONCLUSÕES:Os achados sugerem que a presença de disfluências gagas, fatores qualitativos e comunicativos associados, estresse emocional e atitude familiar inadequada são fatores de risco importantes para a gagueira desenvolvimental familial em meninos.
