27 undergraduate students participated in an experiment on EMG biofeedback. Three groups were employed (visual feedback, audio biofeedback, and control) to determine which group learned to reduce frontalis muscle tension more quickly. All subjects were trained during a 30-min. period for five days. The time consisted of a 10-min. baseline and a 20-min. biofeedback session. Over a 5-day period relaxation in the forehead due to biofeedback improved significantly. More training time yielded an increased relaxation in this area, and most learning occurred during the first two days. The significant interaction of training and time illustrated that the two biofeedback groups produced a more pronounced relaxation in the forehead muscle than did the control group. No significant difference was found between the two biofeedback groups.
27名本科生参与了一项关于肌电图生物反馈的实验。实验采用了三组（视觉反馈、听觉生物反馈和对照组）来确定哪一组能更快地学会降低额肌紧张度。所有受试者在30分钟的时间段内接受了为期五天的训练。这段时间包括10分钟的基线期和20分钟的生物反馈期。在为期5天的时间里，由于生物反馈，前额的放松程度有了显著改善。更多的训练时间使该区域的放松程度增加，并且大多数学习发生在头两天。训练和时间的显著交互作用表明，两个生物反馈组在前额肌肉中产生的放松比对照组更明显。两个生物反馈组之间没有发现显著差异。
