Abstract : Various user trainings were proposed to assist the user in accomplishing Motor Imagery (MI) BCI task, e.g. the use of positive (biased) feedback which is an optimistic representation of one's labeled brain activity has shown to increase performance or learning. On the contrary, in some cases positive feedback decreased while negative increased user learning within one session. In order to better understand the benefits of biased feedback on performance and learning during the BCI training, we consider user states such as workload and the flow state, a state of optimal cognitive control, immersion, and pleasure, which has shown to correlate to performance.
