This study was designed to measure the effects of contingent and noncontingent EMG feedback on hand temperature, anxiety, and locus of control. Two groups of six subjects each were selected on the basis of high test-anxiety scores. The groups participated in a reverse design study in which Group 1 received five sessions of contingent EMG ffedback followed by five sessions of noncontingent feedback. Group 2 received noncontingent feedback followed by contingent feedback. Results indicate a significant order of treatment effect. Subjects who received contingent feedback first produced lower EMG readings, lower test-anxiety scores, and higher hand temperatures during noncontingent feedback sessions. Receiving noncontingent feedback first may actually have interfered with utilizing contingent feedback.
本研究旨在测量有条件和无条件肌电图反馈对手部温度、焦虑和控制点的影响。根据高考试焦虑得分，挑选出两组，每组六名受试者。两组参与了一项反向设计研究，其中第一组接受了五节有条件肌电图反馈训练，随后是五节无条件反馈训练。第二组先接受无条件反馈，然后是有条件反馈。结果表明存在显著的治疗效果顺序。首先接受有条件反馈的受试者在无条件反馈训练期间产生的肌电图读数更低、考试焦虑得分更低、手部温度更高。首先接受无条件反馈实际上可能会干扰对有条件反馈的利用。
