Poster 1: CNV: a neural correlate for stutter frequency and compensation strategies. S. Vanhoutte Affiliation: University of Ghent, Belgium
Abstract: The contingent negative variation (CNV) is a neurophysiological substrate of articulatory preparation. We present a neurogenic stuttering case report in which a speech related CNV task was administered at four different points in time. As stutter frequency
increased, CNV amplitudes at bilateral motor and left frontal regions decreased. Conversely, right frontal areas showed a relative increase in activity. Thus, motor preparation is confirmed to be a decisive factor in stuttering. The amount of its dysfunction seems to be in accordance with stutter frequency. The amplitude of its electrophysiological substrate also seems to reflect right-sided neural compensation strategies.

Poster 2: Speech-motor and phonological skills in adults with persistent developmental stuttering. R. Niepelt
Affiliation: The University of Sheffield, UK
Abstract: This paper describes a first exploration of speech-motor and phonological skills in adults with persistent developmental stuttering. To date, origins, causes, and manifestation of developmental stuttering remain underspecified, and different theories exist which try to explain stuttering. Motor speech difficulties and phonological problems are frequently used as explanations. Much research has been performed considering children who stutter. However, adults with persistent developmental stuttering are rarely investigated, especially, related to features which are described as triggers during childhood for the onset of stuttering. Altogether, twelve participants were assessed with motor and phonological tasks. Results compare performances of adults who do and those who do not stutter.

Poster 3: Evaluating communicative stress in school-aged stutterers by measuring salivary amylase.  S. Murase 
Affiliation: Gifu University, Japan
Abstract: The purpose of this study was to evaluate stress in school-aged stutterers during a conversation with a stranger. Subjects were 22 school-aged stutterers and 20 school-aged
nonstutterers. Salivary amylase levels were measured before and after a 3-min conversation. Results revealed that salivary amylase levels were significantly higher in stutterers before the conversation
than in the controls; however, no significant differences were found between the groups immediately after the conversation. These findings suggest that school-aged stutterers are under high stress before conversing with a stranger, but not during the conversation.

Poster 4: Differences in acoustic structure of voice by PWNS and PWS.  N. Dobrota-Davidovic, D. Soster & J. Otasevic
Affiliation: Institute of psychophysiological Disorders and Speech Patology Belgrade, University of Belgrade, Serbia
Abstract: The voice is a very complex system that has biological, psychological, linguistic and social foundation. As such, it requires a multidisciplinary study and solves the problems of pathology. Applying Multidimensional voice analysis, we monitored the acoustic parameters of the voice. The main goal of this study was to examine differences in the acoustic characteristics of voice in individuals with fluently speech and persons who stutter. The Voice Analysis Laboratory, Kay Elemetrics Cop. Model 4337 was used. The results show that there are statistically significant differences in the compared parameters among the respondents with fluently speech and respondents who stutter.
Keywords: acoustic characteristics of voice, stuttering, fluency

Poster 5: The working memory basis of normal and pathological speech dysfluencies. L. Van der Linden
Affiliation: Université Catholique de Louvain, Belgium
Abstract: We investigated the hypothesis that the production of normal speech dysfluencies is mediated by working memory and that stuttering is characterized by a hypersensitive speech error-monitoring system. Twenty adult PWS and twenty PWNS performed two experiments. First, a dual task experiment was conducted in which participants were asked to perform a network description task while discriminating auditory signals, to investigate the role of attentional resources in speech production. In a second experiment, participants carried out a task that has been shown to rely on the inferior frontal gyrus, a brain structure that is shown to be hyperactive in PWS.

Poster 7: Communication Attitude of Polish Preschool-Age Children Who Stutter. K. Wesierska, M. Vanryckeghem, B. Jeziorczak & B. Wilk
Affiliation: University of Silesia, Logopedic Centre, Poland, University of Central Florida, USA, U of Ghent
Abstract: This poster presents outcomes of a study aimed at comparing communication attitudes among stuttering and nonstuttering Polish-speaking preschoolers using the Polish version of the KiddyCAT. The findings are consistent with those reported in prior internationally-based studies. Outcomes of the present investigation indicate the existence of a statistically significant difference between the attitudes towards communication of these two groups of children (CWS; CWNS).

Poster 8: Survey: perceptions and prejudices towards stuttering & PWS.  M. Tonnis & J. van Ormondt 
Affiliation: Stottercentrum Groningen, The Netherlands
Abstract: The Centre for Stutter Therapy Groningen (NL) and the Stutterpub Groningen will present their survey conducted in the Netherlands (n=685) among stuttering (n=62) and non-stuttering persons
(n=623). In the survey, prejudice and perceptions were examined. The survey shows that people are very tolerant towards stuttering, but lack knowledge about the subject. Symposium participants can see the results of this first survey on the subject, clustered by theme and/or interviewee-group. They can use it to help PWS deal with their stuttering and their idea of how the general public percieves them.

Poster 9: Stuttering and bilingualism: An investigation of the difference in type and frequency of stuttering and other disfluencies during different speech tasks. M. Vanryckeghem, J. Neyt  & L. Hollebeke 
Affiliation: University of Ghent, Belgium & University of Cnetral Florida, USA
Abstract: This study investigates the difference in type and frequency of stuttering and other types of dysfluencies among 15 adults who are native Dutch speakers and have French or English as a second language. Results showed statistically significantly more stuttering in the second language in all speech tasks. The types of stuttering behaviors were not affected by language. Prolongations were observed most frequently. Normal disfluencies also occurred to a greater extent in the second language. Speech rate was found to be statistically significantly higher in the native language compared to second language, and fastest during reading.

Poster 10: Attitudes towards Stuttering in Poland: an Overview of Research.  M. Wesierska, A. Blachnio, A. Przepiorka, K. St. Louis & K. Wesierska                                                                                 Affiliation: University of York, UK, University of Lublin, Poland, West Virginia University, USA & University of Silesia, Poland
Abstract: This poster summarizes the attitudes towards stuttering of four groups of Polish participants who filled out the Public Opinion Survey of Human Attributes - Stuttering (POSHA-S). The samples consisted of members of Polish general public, speech-language pathologists (SLPs), speech pathology students, and students of other disciplines. This poster presents the attitudes towards stuttering and people who stutter from several Polish studies that investigated the extent of knowledge about the disorder of the four populations and the differences between them. Future directions for research and prevention techniques are considered.

Poster 11: Do teachers' attitudes on stuttering contribute to teacher-student relationships? S. Adriaensens & E. Struyf 
Affiliation: University of Antwerp, Belgium                                                                                                        Abstract: A supportive teacher-student relationship serves a protective function for students with special needs. An important factor contributing to teacher-student relationships are teachers' attitudes toward their students. Unfortunately, teachers often hold negative attitudes toward students with disabilities, including students who stutter. Because of the increased risk of experiencing emotional difficulties, it is important to explore the teacher-student relationship with students who stutter. To study the influence of teacher's attitudes toward stuttering on this relationship a mixed method design was set up, using a quantitative (questionnaire: 26 students and 51 secondary education teachers) and qualitative (10 interviews with teachers) approach.

Poster 12: 'Stutter pub': independently and accessible, bringing people together to talk about stuttering.  S. Adriaensens & J. van Ormondt
Affiliation: U of Antwerp, Belgium & Stottercafé Groningen, The Netherlands
Abstract: The stutter pub was originally founded in Rotterdam in 2005. To date there are six stutter pubs across the Netherlands and Belgium. Although the different stutter pubs have their own approach, they underline a common concept; an accessible meeting point to talk about stuttering without any taboos. The gatherings are open to anyone who stutters, irrespective of the fact where (if any) he /she follows therapy. A poster will emphasize the basic principles and offer insight in the experiences of the stutter pub Antwerp and Groningen. A great opportunity for future participants or organizers to ask questions at the organizing teams.

Poster 13: Applicability of OASES scale on Serbian speaking people who stutter.  D. Soster, N. Dobrota-Davidovic, J. Tadic & J. Otasevic
Affiliation: U of Belgrade, Serbia & Institute for Psychophysiological Disorders and Speech Pathology
Abstract:Stuttering problematic is not represented just in speech behaviors, but also in reactions and attitudes towards stuttering. The OASES scale is one of newly developed instruments that can help clinicians to make this assessment, and to evaluate progress of the treatment. We decided to investigate applicability of OASES scale on Serbian speaking people who stutter as the addition to other diagnostic measures that we already use.
Key words: stuttering, adults, OASES scale, treatment

Poster 14: Determining the effect of laser acupunture in treating stutterers. B. Shafiei                Affiliation: Isfahan University of medical sciences, Iran                                                                                Abstract: Acupuncture has been introduced as a therapeutic method for the treatment of stuttering. The aim of the present research was the identification of the results of intervention of laser acupuncture in comparison with speech therapy in stutterers. This clinical - trial and case control research was conducted on 20 stutterers and 20 non-stutterers. In the present study, speech therapy and laser acupuncture were used on 10 persons who had developmental stuttering from childhood. The results were compared with the data of speech therapy and placebo laser in 10 control subjects. All of the subjects were followed up for 12 weeks after the intervention. The obtained data showed that accompanying of speech therapy with laser acupuncture resulted the increasing of maintenance and therapeutic effects of stuttering treatment and decreasing of relapsing. The speech rate and percent of stuttered words before and after the intervention in both groups (A and B) were decreased. Following the results after 12 weeks showed that the results were stable in laser group more than the other group and there was a significant difference between the two groups. The results of the present study showed that using of laser acupuncture therapy accompanying by speech therapy has many effects on the treatment of stuttering.
