This experiment used the integration of a multi-element design with a second baseline to isolate the effect of biofeedback on the control of a target response, heart rate. The results of the experiment indicate that contingent visual heart rate feedback was instrumental in specifically facilitating the control of heart rate and that control was not mediated by the effects of changes in overall arousal level as measured by skin conductance. These results encourage the experimental analysis of biofeedback using single case designs. Further, the design presented herein offers a clinically and experimentally useful methodology for biofeedback research.
本实验采用多因素设计与第二条基线相结合的方法，以分离生物反馈对目标反应（心率）控制的影响。实验结果表明，视情况而定的视觉心率反馈有助于特别促进心率控制，且这种控制并非由皮肤电导率所测量的整体唤醒水平变化的影响所介导。这些结果鼓励使用单病例设计对生物反馈进行实验分析。此外，本文提出的设计为生物反馈研究提供了一种临床和实验上有用的方法。
