This study investigated whether sympathetic activity during a stressful speaking task was an early marker for stuttering chronicity.
Participants were 9 children with persisting stuttering, 23 children who recovered, and 17 children who do not stutter. Participants performed a stress-inducing picture-naming task and skin conductance was measured across three time points.
Findings indicated that at the initial time point, children with persisting stuttering exhibited higher sympathetic arousal during the stressful speaking task than children whose stuttering recovered.
Findings are taken to suggest that sympathetic activity may be an early marker of heightened risk for chronic stuttering.
本研究调查了在有压力的言语任务中交感神经活动是否是口吃慢性化的早期指标。
参与者包括9名持续性口吃儿童、23名已康复的儿童和17名不口吃的儿童。参与者执行一项诱导压力的图片命名任务,并在三个时间点测量皮肤电导率。
研究结果表明,在初始时间点,持续性口吃儿童在有压力的言语任务中表现出比口吃已康复儿童更高的交感神经唤醒水平。
研究结果表明,交感神经活动可能是慢性口吃风险增加的早期指标。
