摘要

Background: People who stutter are often acutely aware that their speech disruptions, halted communication, and aberrant struggle behaviours evoke reactions in communication partners. Considering that eye gaze behaviours have emotional, cognitive, and pragmatic overtones for communicative interactions and that previous studies have indicated increased physiological arousal in listeners in response to stuttering, it was hypothesized that stuttered speech incurs increased gaze aversion relative to fluent speech. The possible importance in uncovering these visible reactions to stuttering is that tliey may contribute to the social penalty associated .with stuttering.Aims: To compare the eye gaze responses of college students while observing and listening to fluent and severely stuttered speech samples produced by the same adult male who stutters.Methods & Procedures: Twelve normally fluent adult college students watched and listened to three 20-second audio-video clips of the face of an adult male stuttering and three 20-second clips of the same male producing fluent speech. Their pupillary movements were recorded with an eye-tracking device and mapped to specific regions of interest (that is, the eyes, the nose and the mouth of the speaker).Outcomes & Results: Participants spent 39% more time fixating on the speaker's eyes while witnessing fluent speech compared with stuttered speech. In contrast, participants averted their direct eye gaze more often and spent 45% more time fixating on the speaker's nose when witnessing stuttered speech compared with fluent speech. These relative time differences occurred as a function of die number of fixations in each area of interest. Thus, participants averted their gaze from the eyes of the speaker more frequently during the stuttered stimuli than the fluent stimuli.Conclusions & Implications: This laboratory study provides pilot data suggesting that gaze aversion is a salient response to the breakdown in communication tliat occur
