虽然生物反馈通常被认为是通过增加对主观相关性的认识来增加对生理状态的自我控制，但相对较少的研究分析了控制（标准生物反馈）和意识（辨别范式）之间的关系。我们假设，这两种技能将推广和促进彼此为812 Hz的EEG振幅（α）。参与者接受了7次控制或辨别Pz α的训练，然后进行了3次其他范式的训练。另一组接受了7次训练，时间在两种类型的训练中平均分配。控制训练的第一组表现出显着的技能概括的歧视任务。然而，相反的情况并非如此，联合任务组在两项任务中的表现并不比其他两组好。这些结果提供了矛盾的支持意识在生物反馈中的作用，并提出可能的改进的歧视范式。(C)2016 Elsevier Inc.

While biofeedback is often said to increase self-control of physiological states by increasing awareness of their subjective correlates, relatively few studies have analyzed the relationship between control (standard biofeedback) and awareness (a discrimination paradigm). We hypothesized that the two skills would generalize and facilitate each other for 812 Hz EEG amplitude (alpha). Participants were given 7 sessions of training to either control or discriminate Pz alpha followed by 3 sessions of the other paradigm. Another group was given 7 sessions with time divided equally between the two types of training. The control-training first group showed significant generalization of skills to the discrimination task. However, the reverse was not true, and the combined task group did no better in either task than the other two groups. These results provide ambivalent support for the role of awareness in biofeedback, and suggest possible improvements in the discrimination paradigm. (C) 2016 Elsevier Inc. All rights reserved.
