Current controversies concerning outcomes of EEG alpha feedback training are at least in part due to methodological differences among different studies. The aim of this paper is to provide future and present researchers in this field with an analysis of methods used in most of the studies published from 1968 to 1976, and to comment on those methodological issues we think most important. These include alpha assessment, training schedules, and uni- versus bidirectional training. This analysis is accomplished in part by a series of tables listing 45 studies and the detailed methodologies used. It is believed that the probabilities of successful feedback enhancement of alpha can be substantially improved by incorporating the following suggestions: (a) employing at least four training sessions, (b) the use of continuous rather than dichotomous feedback, supplemented by periodic quantitative scores of progress, and (c) using training trials of at least 10 minutes' duration.
目前关于脑电图α波反馈训练结果的争议至少部分源于不同研究之间的方法学差异。本文旨在为该领域的现有和未来研究人员分析1968年至1976年期间发表的大多数研究中所使用的方法，并对我们认为最重要的那些方法学问题进行评论。这些问题包括α波评估、训练计划以及单向与双向训练。该分析部分通过一系列列出45项研究及其所使用详细方法的表格来完成。据信，通过纳入以下建议，α波反馈增强成功的概率可得到显著提高：(a) 至少进行四次训练课程；(b) 使用连续而非二分法反馈，并辅以定期的进展定量评分；(c) 使用持续时间至少为10分钟的训练试验。
