背景资料：经过大约30年的脑机接口（BCI）研究，人们对这种现象知之甚少，即一些人-健康人以及患有疾病的人-无法学习BCI控制。为了阐明这一“BCI低效率”的现象，目前的研究调查是否心理参数，如注意广度，个性或动机，可以预测性能在一个单一的会话与BCI控制的感觉运动节律（SMR）调制与motor imageration.Methods：共N=83健康BC！新手参加了会议。心理参数测量与电子测试电池，包括临床，个性和性能测试。预测因素进行了确定由二进制logistic回归analysis.Results：输出变量的双手协调测试（2 HAND）的“总体平均错误持续时间”，这是一个衡量精细运动技能的准确性占11%的方差BCI效率低下。对工作的态度（AHA）测试变量“性能水平”，可以被解释为程度的浓度和神经生理SMR预测器也被确定为显着的预测器SMR BCI performance.Conclusion：在这项研究中测量的心理参数发挥适度的作用，一个会话的性能在BCI控制调制的SMR。(C)2011爱思唯尔有限公司版权所有。
Background: After about 30 years of research on Brain-Computer Interfaces (BCIs) there is little knowledge about the phenomenon, that some people - healthy as well as individuals with disease - are not able to learn BCI-control. To elucidate this "BCI-inefficiency" phenomenon, the current study investigated whether psychological parameters, such as attention span, personality or motivation, could predict performance in a single session with a BCI controlled by modulation of sensorimotor rhythms (SMR) with motor imagery.Methods: A total of N=83 healthy BC! novices took part in the session. Psychological parameters were measured with an electronic test-battery including clinical, personality and performance tests. Predictors were determined by binary logistic regression analyses.Results: The output variable of the Two-Hand Coordination Test (2HAND) "overall mean error duration" which is a measure for the accuracy of fine motor skills accounted for 11% of the variance in BCI-inefficiency. The Attitudes Towards Work (AHA) test variable "performance level" which can be interpreted as a degree of concentration and a neurophysiological SMR predictor were also identified as significant predictors of SMR BCI performance.Conclusion: Psychological parameters as measured in this study play a moderate role for one-session performance in a BCI controlled by modulation of SMR.
