INTRODUCTION The purpose of this study was to investigate whether attribution theory could explain speech-language pathologists (SLPs) perceptions of children with communication disorders such as stuttering. Specifically, it was determined whether perceptions of onset and offset controllability, as well as biological and non-biological attributions for communication disorders were related to wi...

Previous studies suggest that anatomical anomalies [Foundas, A. L., Bollich, A. M., Corey, D. M., Hurley, M., & Heilman, K. M. (2001).

The paper describes experiments where automatic acoustic algorithms initially intended to be used on Czech stuttering speakers were applied on recordings of German stuttering speakers. Four algorithms based on voice activity and abrupt spectral changes detection are introduced. The database consists of 34 speakers. The measure, the number of abrupt spectral changes in speech segments, reached a...

In this article, a selection of theoretical approaches about stuttering is examined. One way of characterizing theories is in terms of whether the problem of stuttering arises at the linguistic or motor levels or in the interaction between the two. A second contrast between theories is in terms of whether they link production together with perception (linked theories, e.g., the covert repair hy...

Stuttering, with its characteristic disruption in verbal fl uency, has been known for centuries; earliest descriptions probably date back to the Biblical Moses’ “slowness of speech and tongue” and his related avoidance behavior (Exodus 4, 10–13). Stuttering occurs in all cultures and ethnic groups (Andrews et al. 1983; Zimmermann et al. 1983), although prevalence might differ. Insofar as many o...

PURPOSE English and Mandarin are the 2 most spoken languages in the world, yet it is not known how stuttering manifests in English-Mandarin bilinguals. In this research, the authors investigated whether the severity and type of stuttering is different in English and Mandarin in English-Mandarin bilinguals, and whether this difference was influenced by language dominance. METHOD Thirty English...

Neuroimaging and transcranial magnetic stimulation provide insights into the neuronal mechanisms underlying speech disfluencies in chronic persistent stuttering. In the present paper, the goal is not to provide an exhaustive review of existing literature, but rather to highlight robust findings. We, therefore, conducted a meta-analysis of diffusion tensor imaging studies which have recently imp...

Communication problems resulting from acquired brain damage are most frequently manifested as motor speech disorders such as dysarthria, syndromes of aphasia, and impairments of pragmatics. A much less common phenomenon is the onset of stuttering in adults who sustain a stroke, traumatic brain injury, or other neurologic events. When stuttering occurs in association with neuropathology, precise...

OBJECTIVES The aim of the current study was to differentiate between neural activity that represents neural anomalies that are responsible for persistent developmental stuttering (PDS) from the activity that is a result of compensating for stuttering. This was done by investigating alterations to the intrinsic functional architecture of speech-language processes of patients with PDS before and ...

Prolonged speech and its variants are widely used in the behavioral treatment of stuttering. Unlike these approaches, which depend on clinician-prescribed speech pattern changes, two behavioral treatment regimens, one for children and another for adults, recently developed at the Australian Stuttering Research Center, promote self monitoring of speech as a means of controlling stuttering. In th...
