| Popis: | The present study was designed to evaluate aspects of central processing and simultaneous laryngeal function in stutterers and nonstutterers using a recently developed continous flow model of phonatory reaction time. Simultaneous measurements were made of P300 brain potentials, laryngeal positioning movements prior to vocal fold closure, and onset of vocal fold vibration in 10 stutterers and 10 nonstutterers. The temporal ordering of these three events was evaluated and differences between the two groups examined. No significant differences were found in the vocal motor or P300 responses. Stutterers and nonstutterers appeared to be using a similar temporal patterning. This patterning may indicate an overlap between sensory and motor processing in phonatory reaction time tasks. Use of the present model with its quantifiable components of laryngeal shift, P300, and onset of vocal fold vibration, can yield valuable information regarding temporal aspects of central processing and laryngeal function. |
