LARYNGEAL ADJUSTMENTS IN STUTTERING: MODIFIED REACTION PARhDIGM*
نویسندگان
چکیده
An experimental paradigm for studying stuttering is described. Simultaneous recordings of the voice and a photo~ electric glottogram were made during speech production in a modified reaction time situation. prel iminary resul ts of one subj ect revealed that some cases of dysfluency (word initial voiceless stop repetitions) were accompanied by one or two extra glottal opening gestures cot'responding to repeated release bursts. Similar "trialand-error" types of glottal movements were also detected during silent delayed response time in other productions that were perceptually judged as fluent. As for the production of words beginning with voiced sounds, unnecessary opening gestures prior to the vocalization for the initial voiced segment It/ere sometimes observed for both fluent and dysfluent utterances. These findings suggest that stuttering is linked to a temporal disruption of the control of the abductory and adductory gestures of the glottis relative to supraglottal articulation and respiratory function.

Physiological bases of acoustic LRT in nonstutterers, mild stutterers, and severe stutterers.
The simple reaction time paradigm, incorporating a variable foreperiod, was used to investigate relative contributions of the respiratory and laryngeal systems to mild and severe stutterers' prolonged acoustic laryngeal reaction time (LRT) values. Prephonatory kinematic data were analyzed in terms of frequency of initiation, timing, and organization of events executed to attain the functional p...

Converging evidence suggests that stuttering is associated with deficits in the planning and execution of speech. Evidence also suggests that the onset, development, and loci of stuttering are related to demands language places on speech motor planning and execution. We combined linguistic and vocal motor assessments to address two questions: 1) Can we identify a subgroup of adult stutterers wh...
متن کاملA muscle spindle abnormity in one laryngeal muscle would be sufficient to cause stuttering.
Muscle spindles are increasingly recognized as playing a pivotal role in the cause of dystonia. This development and own laryngeal observations that support the idea of causally "well-intentioned" stuttering motivated us to present the following hypothesis: stuttering events compensate for a sensory problem that arises when the abductor/adductor ratio of afferent impulse rates from the posterio...
متن کاملChildhood Laryngeal Dystonia Following Bilateral Globus Pallidus Abnormality: A Case Study and Review of Literature
Introduction:Dystonia is a disorder of movement caused by various etiologies. Laryngeal dystonia is caused by the spasm of laryngeal muscles. It is a disorder caused by vocal fold movement in which excessive adduction or abduction of the vocal folds occurs during speech. The pathophysiology of this type of dystonia is not fully known. Some researchers have suggested that basal ganglia structure...
متن کاملChildhood Neurogenic Stuttering Due to Bilateral Congenital Abnormality in Globus Pallidus: A Case Report and Review of the Literature
Objective The basal ganglia are a group of structures that act as a cohesive functional unit. They are situated at the base of the forebrain and are strongly connected with the cerebral cortex and thalamus. Some speech disorders such as stuttering can resulted from disturbances in the circuits between the basal ganglia and the language motor area of the cerebral cortex. Stuttering consists of b...
