Resource measurement using a closed-loop EEG control system

摘要

A technique of conscious control of one's EEG (electroencephalogram) resonance was tested for potential use as an indication of mental resource allocation. An experimental paradigm was developed which incorporated this technique and a number of tasks from the Criterion Task Set (CTS). The objective was to determine if the ability to consciously control EEG resonance varied in a systematic fashion based on the type of CTS task being performed (i.e. different mental resources being tapped). An experimental setup, including a lock-in amplifier system (LAS) and the CTS, was developed. Subjects were trained in loop-closure performance at chosen EEG frequencies. Trained subjects then attempted loop-closure while performing CTS tasks. Experimental methods and preliminary results are addressed.
