The present study aimed to investigate the effectiveness of the frontal-midline theta (fmθ) activity uptraining protocol on attention and working memory performance of older and younger participants.
Thirty-two participants were recruited. Participants within each age group were randomly assigned to either the neurofeedback training (fmθ uptraining) group or the sham-neurofeedback training group.
There was a significant improvement in orienting scores in the older neurofeedback training group. In addition, there was a significant improvement in conflict scores in both the older and young neurofeedback training groups. However, alerting scores failed to increase. In addition, the fmθ training was found to improve working memory function in the older participants. The results further showed that fmθ training can modulate resting EEG for both neurofeedback groups.
Our study demonstrated that fmθ uptraining improved attention and working memory performance and theta activity in the resting state for normal aging adults. In addition, younger participants also benefited from the present protocol in terms of improving their executive function.
The current findings contribute to a better understanding of the mechanisms underlying neurofeedback training in cognitive function, and suggest that the fmθ uptraining protocol is an effective intervention program for cognitive aging.
本研究旨在探究额中线θ(fmθ)活动增强训练方案对老年人和年轻人的注意力和工作记忆表现的有效性。
招募了 32 名参与者。每个年龄组内的参与者被随机分配到神经反馈训练(fmθ 增强训练)组或假神经反馈训练组。
老年神经反馈训练组的定向得分显著提高。此外,在老年和年轻的神经反馈训练组中,冲突得分均有显著提高。然而,警觉得分没有增加。此外,发现 fmθ 训练可改善老年人的工作记忆功能。结果进一步表明,fmθ 训练可以调节神经反馈组的静息 EEG。
本研究表明,fmθ 增强训练可改善正常老年人的注意力和工作记忆表现以及静息状态下的θ 活动。此外,年轻参与者也从本方案中受益,提高了他们的执行功能。
本研究结果有助于更好地理解神经反馈训练对认知功能的作用机制,并表明 fmθ 增强训练方案是认知老化的一种有效干预方案。
