Speech Timing Deficit of Stuttering: Evidence from Contingent Negative Variations
The aim of the present study was to investigate the speech preparation processes of adults who stutter (AWS). Fifteen AWS and fifteen adults with fluent speech (AFS) participated in the experiment. The event-related potentials (ERPs) were recorded in a foreperiod paradigm. The warning signal (S1) was a color square, and the following imperative stimulus (S2) was either a white square (the Go si...
متن کاملEvidence that a motor timing deficit is a factor in the development of stuttering.
PURPOSE To determine whether young children who stutter have a basic motor timing and/or a coordination deficit. METHOD Between-hands coordination and variability of rhythmic motor timing were assessed in 17 children who stutter (4-6 years of age) and 13 age-matched controls. Children clapped in rhythm with a metronome with a 600-ms interbeat interval and then attempted to continue to match t...
متن کاملContingent negative variation (CNV) associated with sensorimotor timing error correction
INTRODUCTION Detection and subsequent correction of sensorimotor timing errors are fundamental to adaptive behavior. Using scalp-recorded event-related potentials (ERPs), we sought to find ERP components that are predictive of error correction performance during rhythmic movements. METHOD Healthy right-handed participants were asked to synchronize their finger taps to a regular tone sequence ...
متن کاملThe contingent negative variation (CNV): timing isn’t everything
When participants time intervals ranging from several hundred milliseconds to several seconds a negative polarity waveform, known as the contingent negative variation (CNV), manifests in the ongoing electroencephalogram (EEG). The perceptual and cognitive functions underlying this component are subject to ongoing debate. Moreover, recent evidence suggests that the link between the CNV and behav...
متن کاملBehavioral and multimodal neuroimaging evidence for a deficit in brain timing networks in stuttering: a hypothesis and theory
The fluent production of speech requires accurately timed movements. In this article, we propose that a deficit in brain timing networks is one of the core neurophysiological deficits in stuttering. We first discuss the experimental evidence supporting the involvement of the basal ganglia and supplementary motor area (SMA) in stuttering and the involvement of the cerebellum as a possible mechan...
