ABSTRACT The performance of subjects ( S s) receiving contingent feedback in an eyes‐closed alpha enhancement setting was contrasted with changes in alpha of S s receiving random feedback and no feedback. In addition, comparisons were made between: 1) binary and continuous feedback signals; 2) integrated and criterion alpha as dependent variables; and 3) eyes‐open and eyes‐closed alpha enhancement tasks. It was found that: 1) Increases in emitted occipital alpha under eyes‐closed conditions are related to contingent reinforcement. 2) Proportional feedback was most efficient in the rapid development of eyes‐closed training. 3) Larger changes in alpha were seen during eyes‐open than during eyes‐closed training. 4) Binary feedback appeared to be more efficient in increasing eyes‐open alpha response. 5) No relationships between the ability to perform the eyes‐open and eyes‐closed alpha enhancement tasks were found within S s.
