Performance Enhancement Training Effects on Attention: A Case Study

The purpose of this case study was to evaluate the effects of alpha-increase biofeedback training on human attention. A healthy twenty-three year old male college student had undergone twenty-three sessions of alpha- increase biofeedback (8–13 Hz) at PZ electrode site for a period of eleven weeks. Pre-and Post- visual TOVA CPT test was administered to assess the changes in reaction times and their variability. QEEG evaluation was conducted prior as well as upon the completion of the study. The results of the TOVA test clearly indicate an improvement in individual's reaction time and the reaction time variability. Statistical analysis showed that before and after QEEG evaluations were within normal limits
