当金钱奖励被用来操纵外在动机时，动机对健康受试者脑机接口（BCI）的表现有中度影响。然而，严重瘫痪患者的动机可能主要是内在的，因此，内在动机可能更强大。此外，参与脑机接口研究的健康受试者可能有内在动机，因为他们可能希望为研究做出贡献，因此，金钱奖励的外在动机不如研究内容重要。在这方面，动机可以被定义为“帮助的动机”。本研究的目的是探讨具有高帮助动机和高度共情的被试是否在事件相关电位（P300-BCI）控制的脑机接口（BCI）中表现更好。我们将N = 20名健康的年轻参与者naïve纳入BCI，并根据他们参与BCI研究的动机将他们分为低动机组和高动机组。通过关于脑机接口的有趣或无聊的演讲以及帮助患者的可能性，进一步操纵动机。帮助动机既不影响脑机接口的表现，也不影响P300振幅。事后，受试者根据他们的透视能力被重新分组。我们发现，与同理心较高的参与者相比，持不同观点能力较低的参与者的顶叶电极P300振幅明显较高，因此同理心较低。缺乏动机对脑机接口性能的影响与先前的发现相矛盾，因此需要进一步的研究。我们推测，对于潜在需要脑机接口的患者来说，具有较高同理心的受试者是良好的观点接受者，他们可能更情绪化，因此，更不能够将注意力分配到手头的脑机接口任务上。
Motivation moderately influences brain–computer interface (BCI) performance in healthy subjects when monetary reward is used to manipulate extrinsic motivation. However, the motivation of severely paralyzed patients, who are potentially in need for BCI, could mainly be internal and thus, an intrinsic motivator may be more powerful. Also healthy subjects who participate in BCI studies could be internally motivated as they may wish to contribute to research and thus extrinsic motivation by monetary reward would be less important than the content of the study. In this respect, motivation could be defined as “motivation-to-help.” The aim of this study was to investigate, whether subjects with high motivation for helping and who are highly empathic would perform better with a BCI controlled by event-related potentials (P300-BCI). We included N = 20 healthy young participants naïve to BCI and grouped them according to their motivation for participating in a BCI study in a low and highly motivated group. Motivation was further manipulated with interesting or boring presentations about BCI and the possibility to help patients. Motivation for helping did neither influence BCI performance nor the P300 amplitude. Post hoc, subjects were re-grouped according to their ability for perspective taking. We found significantly higher P300 amplitudes on parietal electrodes in participants with a low ability for perspective taking and therefore, lower empathy, as compared to participants with higher empathy. The lack of an effect of motivation on BCI performance contradicts previous findings and thus, requires further investigation. We speculate that subjects with higher empathy who are good perspective takers with regards to patients in potential need of BCI, may be more emotionally involved and therefore, less able to allocate attention on the BCI task at hand.
