Contemporary issues with stuttering: The Fourth Croatia Stuttering Symposium.

Purpose: During the 2019 Fourth Croatia Clinical Symposium, speech-language pathologists (SLPs), scholars, and researchers from 29 countries discussed speech-language pathology and psychological practices for the management of early and persistent stuttering. This paper documents what those at the Symposium considered to be the key contemporary clinical issues for early and persistent stuttering.

Methods: The authors prepared a written record of the discussion of Symposium topics, taking care to ensure that the content of the Symposium was faithfully reproduced in written form.

The Pathogenesis, Assessment and Treatment of Speech Fluency Disorders.

Background: Approximately 1% of children and adolescents, 0.2% of women, and 0.8% of men suffer from stuttering, and lesser numbers from cluttering.

Measuring Stuttering in Preschool-Aged Children across Different Languages: An International Study.

Background/aims: Many speech-language pathologists (SLPs) are working in linguistically diverse communities and have to identify and measure stuttering in a language other than their own. The aim of the present study was to extend our understanding of how well SLPs can measure stuttering in other languages and to encourage collaboration between SLPs across cultures.

Methods: Speech samples consisted of seven preschool-aged children each speaking one of the following languages: Danish, English, French, German, Greek, Italian, and Persian (Farsi).

Dual tasking and stuttering: from the laboratory to the clinic.

Purpose: The aim of the three studies in this article was to develop a way to include dual tasking in speech restructuring treatment for persons who stutter (PWS). It is thought that this may help clients maintain the benefits of treatment in the real world, where attentional resources are frequently diverted away from controlling fluency by the demands of other tasks.

Method: In Part 1, 17 PWS performed a story-telling task and a computer semantic task simultaneously.

Cognitive processing load as a determinant of stuttering: summary of a research programme.

The present paper integrates the results of experimental studies in which cognitive differences between stuttering and nonstuttering adults were investigated. In a monitoring experiment it was found that persons who stutter encode semantic information more slowly than nonstuttering persons. In dual-task experiments the two groups were compared in overt word-repetition and sentence-production experiments.

Effects of category and rhyme decisions on sentence production.

The aim of the present experiment was to investigate differences between persons who stutter and persons who do not stutter during the production of sentences in a single task versus two dual-task conditions. Participants were required to form a sentence containing 2 unrelated nouns. In dual-task conditions, rhyme and category decisions were used as secondary tasks.

Effects of concurrent cognitive processing on the fluency of word repetition: comparison between persons who do and do not stutter.

Unlabelled: This study investigated how silent reading and word memorization may affect the fluency of concurrently repeated words. The words silently read or memorized were phonologically similar or dissimilar to the words of the repetition task. Fourteen adults who stutter and 16 who do not participated in the experiment.

Spontaneous imitation of fundamental frequency and speech rate by nonstutterers and stutterers.

Speech can be described either in terms of acoustics, as a perceptual outcome, or as a motor event. Central to theories of speech perception and production is an attempt to describe how these aspects of speech are interrelated. The present experiment investigated how the nonstutterers' and stutterers' reproductions of acoustically presented interrogative sentences were influenced by experimental variations of intonation (sentence initial vs.

Online sentence processing in adults who stutter and adults who do not stutter.

This study had two specific aims. The first aim was to investigate whether, during a silent reading task, persons who stutter encode phonological and semantic information move slowly then persons who do not stutter. The second aim was to investigate how the syntactic context of stimulus sentences influences the speed of coding.

In vitro-in vivo correlation of a modified-release oral form of ketotifen: in vitro dissolution rate specification.

The dissolution rate profile of a new modified-release (MR) oral tablet of ketotifen (Zaditen SRO tablet, Sandoz Ltd.) was determined under different conditions (pH, rpm, paddle or basket) with the U.S.

Differences between stutterers' and nonstutterers' short-term recall and recognition performance.

Longer rehearsal times presumably reduce the efficiency of rehearsal and, hence, of short-term recall. The present experiment examined the question as to whether the slower subvocalization rate of people who stutter is correlated with inferior short-term serial recall and recognition performance. Rate of overt articulation was taken as a measure of rehearsal time.

Subvocalization and reading rate differences between stuttering and nonstuttering children and adults.

The hypothesis tested was that stutterers subvocalize more slowly than nonstutterers and that they need more time for the overt production of the fluent parts of their speech. We also investigated whether rate differences could only be observed for those words on which the stutterers expect to stutter. Fifty-nine school children (27 stutterers and 32 nonstutterers) and 19 adults (18 stutterers and 21 nonstutterers) performed a reading task in which a noun was presented together with its definite article.

Enantiomer resolution and assay of propionic acid-derived herbicides in formulations by using chiral liquid chromatography and achiral gas chromatography.

Enantiomers of 6 propionic acid-derived herbicides in the form of their esters were resolved using liquid chromatography with a chiral column. Free acids are converted to methyl esters by means of a BF3-catalyzed reaction. Chromatographic resolutions for 6 of 8 herbicides investigated were in the range of 2 to 4.

Determination of polychlorinated dibenzo-p-dioxins and dibenzofurans in commercial pentachlorophenols by combined gas chromatography-mass spectrometry.

Samples of commercial pentachlorophenol (PCP) and its sodium salt (PCP-Na) were examined for the presence of polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs), using a rapid, highly specific method of analysis. Phenolic compounds are removed by alkaline extraction, and the neutral components are fractionated on an alumina minicolumn. After gas chromatographic separation, individual PCDDs and PCDFs are detected by mass fragmentography and their presence is confirmed by complete mass spectral analysis.
