While decades of research have investigated and technically improved brain–computer interface (BCI)‐controlled applications, relatively little is known about the psychological aspects of brain–computer interfacing. In 35 healthy students, we investigated whether extrinsic motivation manipulated via monetary reward and emotional state manipulated via video and music would influence behavioral and psychophysiological measures of performance with a sensorimotor rhythm (SMR)‐based BCI. We found increased task‐related brain activity in extrinsically motivated (rewarded) as compared with nonmotivated participants but no clear effect of emotional state manipulation. Our experiment investigated the short‐term effect of motivation and emotion manipulation in a group of young healthy subjects, and thus, the significance for patients in the locked‐in state, who may be in need of a BCI, remains to be investigated.
