论文摘要
大脑计算机界面（BCI）将电生理信号从大脑解码为由计算机或机器人设备执行的动作。汽车图像BCI（MI BCI）依赖于身体运动的想象力，但是并非所有用户都可以生成控制MI BCI所需的大脑活动。新手用户MI BCI表现的这种差异可能是由于他们的认知能力。在这项研究中，研究了空间能力和视觉空间记忆对MI BCI性能的影响。五十四名新手用户参加了MI BCI任务和两项认知测试。测量了三个反馈会话中空间能力和视觉空间记忆对BCI任务错误率的影响。我们的结果表明，通过心理旋转测试评估的空间能力与MI BCI的性能无关，但是通过设计组织测试评估的视觉空间记忆在高能力用户中较高。我们的发现可以通过参与者筛查和认知技能培训来优化MI BCI培训范例。
Brain computer interfaces (BCI) decode the electrophysiological signals from the brain into an action that is carried out by a computer or robotic device. Motor imagery BCIs (MI BCI) rely on the user s imagination of bodily movements, however not all users can generate the brain activity needed to control MI BCI. This difference in MI BCI performance among novice users could be due to their cognitive abilities. In this study, the impact of spatial abilities and visuospatial memory on MI BCI performance is investigated. Fifty four novice users participated in a MI BCI task and two cognitive tests. The impact of spatial abilities and visuospatial memory on BCI task error rate in three feedback sessions was measured. Our results showed that spatial abilities, as assessed by the Mental Rotation Test, were not related to MI BCI performance, however visuospatial memory, assessed by the design organization test, was higher in high aptitude users. Our findings can contribute to optimization of MI BCI training paradigms through participant screening and cognitive skill training.
