Abstract

A double reversal single-subject experimental design was used to study the effects of visual feedback on the hemispheric alpha asymmetries of a male subject during a linguistic task. Results indicated that the subject demonstrated flexibility in hemispheric alpha and corresponding processing strategies employed when an alpha biofeedback procedure was used. These results provide further support for the notion that right and left hemispheric activation is associated with different, yet compatible, cognitive strategies and that both can be manipulated under conditions of feedback.

摘要

采用双反转单受试者实验设计，研究视觉反馈对一名男性受试者在语言任务期间半球α不对称性的影响。结果表明，当使用α生物反馈程序时，该受试者在半球α及相应采用的加工策略方面表现出灵活性。这些结果为以下观点提供了进一步支持：左右半球激活与不同但兼容的认知策略相关，并且在反馈条件下两者均可被操控。
