Personality traits (PTs) are predictors of the success of control of brain-computer interfaces (BCIs); however, it is unknown how the PTs that are optimal for BCI control changes during training. The paper for the first time analyzes the correlations between PTs and the accuracy of the classification (AC) of brain states in imagining the movements of the hands, feet, and locomotion during 10-day training of ten volunteers in BCI control. In the first 3 days of training, the AC is higher for more stressed and anxious volunteers; in the last days, for calmer ones. In the middle of the training period, AC is higher in low-demonstrativeness persons, it is more pronounced when imagining foot movements. Correlations of low demonstrativeness, as well as of foresight and self-control with AC when imagining foot movements are revealed significantly more often than when imagining hand movements and locomotions. During almost the entire period of training, AC with locomotion imagination is higher in individualists. The results make it possible to propose individually-oriented recommendations for the use of BCI based on the imagination of movements for the rehabilitation of patients with motor disorders.
人格特质（PTs）是脑机接口（BCIs）控制成功的预测指标；然而，尚不清楚在训练过程中，最适合 BCI 控制的 PTs 是如何变化的。本文首次分析了人格特质与分类准确性（AC）之间的相关性，即在 10 名志愿者进行为期 10 天的 BCI 控制训练期间，想象手部、脚部和运动时大脑状态的分类准确性（AC）。在训练的前 3 天，压力更大和焦虑程度更高的志愿者的 AC 更高；在最后几天，情况则相反。在训练中期，低表现欲的人的 AC 更高，在想象脚部运动时更为明显。当想象脚部运动时，低表现欲、前瞻性和自我控制与 AC 的相关性比想象手部运动和运动时更显著。在训练的几乎整个过程中，个体主义者的运动想象 AC 更高。这些结果使得可以根据运动想象为运动障碍患者的康复提出基于个体的 BCI 使用建议。
