The role of agency in neurofeedback performance
Résumé
Neurofeedback (NF) aims to elicit voluntary modulation of neural activity by providing online feedback (FB). In Motor Imagery (MI) NF, participants reduce sensorimotor activity by imagining movements. Providing FB improves modulation relative to simple MI. Yet, a lot of NF participants fail to learn to modulate targeted activity. Most studies feature abstract FB obscuring the causal link between the MI task and the FB. This may reduce the sense of agency, which is rooted in the consistency between predicted and actual sensory outcomes. FB transparency could increase this consistency, yielding better sense of agency and in turn better NF performance. In this study, we tested this hypothesis in a MI-NF EEG-based protocol with different FB conditions.
