Abnormal speech sound representation in persistent developmental stuttering.
OBJECTIVES To determine whether adults with persistent developmental stuttering (PDS) have auditory perceptual deficits. METHODS The authors compared the mismatch negativity (MMN) event-related brain potential elicited to simple tone (frequency and duration) and phonetic contrasts in a sample of PDS subjects with that recorded in a sample of paired fluent control subjects. RESULTS Subjects ...
متن کاملThe Effect of Word Meaning on Speech DysFluency in Adults with Developmental Stuttering
Objectives: Stuttering is one of the most prevalent speech and language disorders. Symptomology of stuttering has been surveyed from different aspects such as biological, developmental, environmental, emotional, learning and linguistic. Previous researches in English-speaking people have suggested that some linguistic features such as word meanings may play a role in the frequency of speech non...
متن کاملAttentional Demand of Speech in Children and Adolescents with Developmental Stuttering
Background & Objective: Stuttering is a prevalent disorder in children and adolescents. Because attention is the only fuel resource for cognitive functions and the language have high cognitive functions, then it is possible that speech difficulties are related to attention deficit. The purpose of this study was to investigate the attentional demand of speech in children and adolescents with dev...
متن کاملDisconnection of speech-relevant brain areas in persistent developmental stuttering.
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...
متن کاملSimilarities in speech and white matter characteristics in idiopathic developmental stuttering and adult-onset stuttering.
Adult-onset stuttering (AS) typically occurs following neurological and/or psychological trauma, considered different from developmental stuttering (DS), which starts during early childhood with few if any new cases reported after adolescence. Here we report four cases of AS, two with apparent psychological trigger and two without, none with evidence of neurological injury, and none conforming ...
