Seventy-seven undergraduates, primed for autonomous or controlled motivation, were videotaped and physiologically monitored during a stressful interview and subsequent speech. Interview videotapes were coded for behavioral measures of threat response; speech videotapes were coded for performance. It was hypothesized that relative to controlled motivation, autonomous motivation would decrease interview threat response and enhance speech performance, and that threat response would mediate the effect of motivation on performance. Results support the prediction across measures of verbal, paralinguistic, smiling, vocal fundamental frequency, and cardiovascular response. Autonomously primed participants continued to show less cardiovascular threat throughout the later speech and gave better speeches. Finally, speech performance was mediated by interview threat response. Results demonstrate that relative to controlled motivation, autonomous motivation lowers threat response, which enhances performance.
77 名大学生在接受压力面试和随后的演讲时，根据自主或控制动机进行了录像和生理监测。面试录像带被编码为威胁反应的行为措施；演讲录像带被编码为表现。假设与控制动机相比，自主动机将减少面试威胁反应并提高演讲表现，并且威胁反应将调节动机对表现的影响。结果支持跨言语、副语言、微笑、声音基本频率和心血管反应的测量结果。自主激发的参与者在随后的演讲中仍然表现出较低的心血管威胁，并给出了更好的演讲。最后，演讲表现受到面试威胁反应的调节。结果表明，与控制动机相比，自主动机降低了威胁反应，从而提高了表现。
