Twenty-four volunteer college students who were regular drug users were randomly allocated to three training groups of equal size: alpha feedback, EMG feedback and a joked control group. The subjects were unaware of which feedback condition they received and were asked to practise at home during a six-month follow-up period in order to achieve a relaxed state similar to that experienced during training. No group was successful in retaining gains made in their alpha levels during each session, but the EMG group significantly reduced their muscular activity during training and retained the improvement during follow-up. The alpha and joked groups did not greatly improve their EMG during training but at follow-up achieved the same levels as the EMG group. There was evidence to suggest that a reduction in drug use among light and medium users was maintained during follow-up. Significant and lasting improvements were made by each group in the duration and quality of their sleep and anxiety levels were reduced.
24名经常使用毒品的大学生志愿者被随机分成三个规模相等的训练组:α波反馈组、肌电图反馈组和一个玩笑对照组。受试者不知道自己接受的是哪种反馈条件,并被要求在为期六个月的随访期间在家中练习,以达到与训练期间相似的放松状态。没有一个组能够在每次训练中保持其α波水平的提高,但肌电图组在训练期间显著降低了肌肉活动,并在随访期间保持了改善。α波组和玩笑组在训练期间肌电图没有很大改善,但在随访时达到了与肌电图组相同的水平。有证据表明,轻度和中度使用者的吸毒量在随访期间保持下降。每个组在睡眠时长和质量方面都有显著且持久的改善,焦虑水平也有所降低。
