Developmental stuttering is a disruption in normal speech fluency and rhythm. Developmental stuttering usually manifests between 6 and 9 years of age and may persist in adulthood. At present, the exact etiology of developmental stuttering is not fully clear. Besides, the dopaminergic neurological component is likely to have a causal role in the manifestation of stuttering behaviors. Actually, s...

Given that most current Structure From Motion (SFM) algorithms cannot recover true motion estimates, it is important to understand the impact such motion errors have on the shape reconstruction. In this paper, various robustness issues surrounding different types of quadratic shape estimates recovered from motion cue are addressed. We present a theoretical model to understand the impact that er...

Given that most current Structure From Motion (SFM) algorithms cannot recover true motion estimates, it is important to understand the impact such motion errors have on the shape reconstruction. In this paper, we present a theoretical model to understand the impact that errors in the motion estimates have on shape recovery. Using this model, we focus on the recovery of second order shape under ...

UNLABELLED The possible relation between stuttering and the basal ganglia is discussed. Important clues to the pathophysiology of stuttering are given by conditions known to alleviate dysfluency, like the rhythm effect, chorus speech, and singing. Information regarding pharmacologic trials, lesion studies, brain imaging, genetics, and developmental changes of the nervous system is reviewed. The...

UNLABELLED Speech-language pathologists (SLPs) are advised to consider the distress of preschoolers and parents along with the social consequences of the child's stuttering when deciding whether to begin or delay treatment. Seventy-seven parents completed a survey that yielded quantitative and qualitative data that reflected their perceptions of the impact of stuttering on their children and th...

Turner Syndrome (TS) is the most common chromosomal anomaly in women. Its psychiatric manifestations have not been clearly defined. Occurrence of schizophrenia is higher in patients with TS than in the normal population. The literature has reported instances associating stuttering as a side effect of antipsychotic drugs, particularly clozapine-induced stuttering. We found only one case report d...

PURPOSE Live oral or recorded video presentations on stuttering were delivered to high school students in order to determine the extent to which their attitudes toward stuttering could be improved. METHODS A classroom teacher administered the Public Opinion Survey of Human Attributes-Stuttering (POSHA-S) to two health classes before and after an oral live presentation by a person who stutters...

UNLABELLED The present study examined the relationship between anxiety, attitude toward daily communication, and stuttering symptomatology in adolescent stuttering. Adolescents who stuttered (n=19) showed significantly higher levels of trait, state and social anxiety than fluent speaking controls (n=18). Trait and state anxiety was significantly associated with difficulty with communication in ...

CONTEXT The speech rate is one of the parameters considered when investigating speech fluency and is an important variable in the assessment of individuals with communication complaints. OBJECTIVE To correlate the stuttering severity index with one of the indices used for assessing fluency/speech rate. DESIGN Cross-sectional study. SETTING Fluency and Fluency Disorders Investigation Labor...

BACKGROUND The neuronal basis of persistent developmental stuttering is unknown. The disorder could be related to a reduced left hemisphere dominance, which functional neuroimaging data suggest might lead to right hemispheric motor and premotor overactivation. Alternatively, the core deficit underlying stuttering might be located in the speech-dominant left hemisphere. Furthermore, magnetoencep...
