Memory performance has been reported to be associated with electroencephalogram (EEG) alpha activity. This study aimed to improve short term memory performance by individual alpha neurofeedback training (NFT). With appropriate protocol designed for NFT, the experimental results showed that the participants were able to learn to increase the relative amplitude in individual alpha band during NFT and short term memory performance was significantly enhanced by 20 sessions of NFT. More importantly, further analysis revealed that the improvement of short term memory was positively correlated with the increase of the relative amplitude in the individual upper alpha band during training. In addition, effective strategies for individual alpha training varied among individuals and the most successful mental strategies were related to positive thinking.
记忆表现与脑电图（EEG）α活动有关。本研究旨在通过个体α神经反馈训练（NFT）来提高短期记忆表现。通过为 NFT 设计的适当方案，实验结果表明参与者能够学会在 NFT 期间增加个体α频段的相对振幅，并且 NFT 的 20 个疗程可以显著提高短期记忆表现。更重要的是，进一步的分析表明，短期记忆的改善与训练过程中个体上α频段的相对振幅的增加呈正相关。此外，个体α训练的有效策略因人而异，最成功的心理策略与积极思考有关。
