本研究探讨了三种反馈模式（视觉-言语，言语-定量，言语-定性）的能力30名正常老年人匹配三种不同的说话速度（慢，平均，快）的影响。10名受试者被随机分配到每个反馈条件。每个受试者都被要求以三种说话速率中的每一种产生刺激短语，给鲍比买个甜甜圈。受试者在视觉-言语模式下通过PM训练器接收话语持续时间的视觉反馈，并从实验者那里获得言语反馈，表明受试者在匹配指定的说话速率时的准确性。在言语-定量条件下的反馈包括言语信息，表明受试者在匹配每个说话速率时的准确性。口头定性条件包括口头反馈相对于受试者的能力，以配合说话的速度，虽然反馈是不太精确比其他条件。结果表明，视觉言语和言语定量反馈导致显着更好的性能比言语定性反馈在匹配的语速，特别是当任务变得更加困难。这些结果对言语障碍人群中类似任务的训练具有影响。
The present study investigated the effects of three feedback modes (visual-verbal, verbal-quantitative, and verbal-qualitative) on the ability of 30 normal geriatric individuals to match three different speaking rates (slow, average, and fast). Ten subjects were randomly assigned to each feedback condition. Each subject was instructed to produce the stimulus phrase,Buy Bobby a doughnut, at each of the three speaking rates. Subjects in the visual-verbal mode received both visual feedback of the utterance duration via a PM Trainer and verbal feedback from the experimenter indicating the subject's accuracy in matching the specified speaking rate. Feedback during the verbal-quantitative condition consisted of verbal information indicating the subject's accuracy in matching each speaking rate. The verbal-qualitative condition consisted of verbal feedback relative to the subject's ability to match speaking rate, although the feedback was less precise than in the other conditions. Results suggest that visual-verbal and verbal-quantitative feedback lead to significantly better performance than verbal-qualitative feedback in matching speaking rate, particularly when the task becomes more difficult. These results have implications for the training of a similar task in speech-disordered populations.
