本研究的目的是评估工作记忆与 BCI 表现之间的关系。参与者参加了两个单独的会议。第一节由三项计算机化任务组成。 LSWM 用于测量工作记忆，TPVT 用于测量一般智力，DCCS 用于测量执行功能，特别是认知灵活性。第二部分包括基于 P300 的 BCI 抄写任务。结果表明，工作记忆和一般智力都是 BCI 表现的重要预测因素。这表明工作记忆训练可用于提高 BCI 任务的表现。工作记忆训练可能有助于减少 BCI 性能中存在的部分个体差异，从而允许更广泛的用户成功操作 BCI 系统，并提高当前用户的 BCI 性能。
The purpose of the present study is to evaluate the relationship between working memory and BCI performance. Participants took part in two separate sessions. The first session consisted of three computerized tasks. The LSWM was used to measure working memory, the TPVT was used to measure general intelligence, and the DCCS was used to measure executive function, specifically cognitive flexibility. The second session consisted of a P300-based BCI copy-spelling task. The results indicate that both working memory and general intelligence are significant predictors of BCI performance. This suggests that working memory training could be used to improve performance on a BCI task. Working memory training may help to reduce a portion of the individual differences that exist in BCI performance allowing for a wider range of users to successfully operate the BCI system as well as increase the BCI performance of current users.
