本研究考察了流利的听者对口吃的心理生理反应。具体地说，皮肤电导和心率的变化是从观看口吃者大声朗读的一分钟视频语音样本时不口吃的成年人身上测量的。15名成年参与者观察了三个口吃和三个流利的语音样本，这些样本按随机顺序呈现，每隔两分钟进行一次相互刺激。结果显示，与观看流利的语音样本相比，观察口吃引起皮肤电导显著增加，心率显著减慢。这些发现表明，听者从生理上被口吃唤醒，并且似乎对口吃保持着不愉快的感觉。此外，口吃样本期间心率的减速也表明，与流利的语音样本相比，听者可能更关注口吃的语音样本。我们推测，异常和异常的口吃行为可能模拟了镜像神经元机制，从而引发了与之相关的情绪唤醒。这种生理唤醒可能为听者对口吃者的负面刻板印象提供了情感根源。(C)2005 Elsevier B.V.保留所有权利。
The present study examined the psychophysiological responses of fluent listeners to stuttered speech. Specifically, skin conductance and heart rate changes were measured from adults who do not stutter while watching one-minute video speech samples of persons stutter read aloud. Fifteen adult participants observed three stuttered and three fluent speech samples, presented in random order with a two-minute interstimulus intervals. Results revealed that observing stuttered speech evoked a significant increase in skin conductance and a significant deceleration in heart rate relative to watching fluent speech samples. These findings suggest that listeners are physiologically aroused by stuttering and appear to maintain feelings of unpleasantness to stuttered speech. Further, deceleration in heart rate during stuttered samples also suggest that listeners may be paying more attention to the stuttered speech samples as compared to the fluent speech samples. We speculate that aberrant and anomalous stuttering behaviors probably simulate the mirror neuronal mechanism eliciting the emotional arousal associated within them. Such physiological arousal may provide the emotional genesis to the listener's negative stereotypical perceptions towards people who stutter. (c) 2005 Elsevier B.V. All rights reserved.
