Project Title: 

Conscious Mental Monitoring Achieved By Neurofeedback and Its Relationship to EEG Alpha

Project Description: 

Advancements in science and technology increasingly demands attention control and more cognitive functioning, yet very little is known the mechanisms and mental states to meet these demands. We propose that conscious mental monitoring achieved by neurofeedback is the way to enhance attention control and to provide insights into the conscious experience of the self-regulating mind. Neurofeedback paradigms, research methods in which subjects learn to self-regulate their own neural activity, may be the framework to integrate neurophysiological data and first-person accounts, which would to further examine the underlying mechanisms of volition over conscious experience. In this experiment, we investigate the state of mind in which individuals monitor and adjust their task-independent, introspective experience in order to enhance their electroencephalogram alpha activities (EEG alpha). Participants are instructed to monitor and regulate their conscious experience according to their own neurofeedback. Following each trial, participants report their mental states and regulation strategies during the trial, corresponding to when they heard the tone feedback, in writing. Research suggests that alpha brain waves play an active role in cognitive processing and top-down self-regulations, and that higher alpha are markers for higher cognitive functioning. Thus, we propose that task-independent conscious activities have direct effects on EEG alpha enhancement, in turn positively affect cognitive functioning, and hope to provide insights on various successful strategies. Results indicate possible correspondences between EEG alpha patterns and self-reported mental state, suggesting the method may have potential as an introspective therapy.
