The Impact of Self-Disclosure and Strategies for Communication Competence on Professors' Perceptions and Evaluations of Students Who Do and Do Not Stutter

Purpose: The purpose of this study was to examine the impact of self-disclosure and strategies for communication competence on perceptual ratings and performance evaluations of undergraduate students who do and do not stutter by professors who require oral presentations. Method: Two hundred thirty-eight college instructors who require oral presentations in their classes participated in this study. Each participant viewed one video of six possible randomized conditions varying according to the presence and disclosure of stuttering (i.e., fluent, stuttering, stuttering + disclosure) and level of communication competence (i.e., high vs. low). Participants evaluated public speaking performance against a standardized rubric and rated the student along 16 personality traits. Results: Results of separate 2 × 3 analyses of variance revealed that professors perceived a student who disclosed stuttering, compared to the identical video without disclosure, more positively overall. Significant interactions between fluency (i.e., presence vs. absence of stuttering vs. disclosure of stuttering) and communication competence (i.e., high vs. low) were found for overall performance evaluation scores. The video during which the student disclosed stuttering and presented with low communication competence was given a higher score than the identical video without disclosure. Conclusions: Professors respond positively to both strategies for high communication competence and self-disclosure. High communication competence behaviors mitigate positive feedback bias. Disclosure results in improved positive perceptions across levels of communication competence. For students presenting with low communication competence, disclosure may improve evaluation of performance in oral presentations. The greatest perceptual and evaluative benefits were achieved with the combination of the two strategies.
