Why visual and vocal interview cues can affect interviewers' judgments and predict job performance.
研究通过视频面试发现，声音线索（如音高、语速）和视觉线索（如微笑、眼神）能预测工作绩效，且面试官对候选人的好感、信任等个人反应是解释这些关系的关键。
Using videotaped interviews with 60 managers in utility companies, the authors found that a composite of vocal interview cues (pitch, pitch variability, speech rate, pauses, and amplitude variability) correlated with supervisory ratings of job performance (r = .18,p < .05).Using videotaped interviews with 110 managers in a news-publishing company, the authors found that the same composite of vocal cues correlated with performance ratings (r = .20,p < .05)and with interviewers' judgments (r -.20, p < .05)and that a composite of visual cues (physical attractiveness, smiling, gaze, hand movement, and body orientation) correlated with performance ratings (r = .14,p < .07)and with interviewers' judgments (r = .21,p < .05).Results of tests of mediation effects indicate that personal reactions such as liking, trust, and attributed credibility toward interviewees explain relationships (a) between job performance and vocal cues and (b) between interviewers' judgments and both visual and vocal cues.Empirical research has firmly established that nonverbal visual cues displayed by interviewees affect interviewers' judgments about their suitability for employment (e.g.,
