Summary
This study investigates the efficacy of neurofeedback training in improving reaction time among elderly, physically inactive males. The research was motivated by the well-documented decline in cognitive and motor functions associated with aging, specifically the increase in reaction time due to reduced ability to predict stimuli and slower neural processing. Neurofeedback, a non-invasive technique that allows individuals to self-regulate brain wave activity, was selected as a potential intervention to mitigate these age-related cognitive deficits. The study employed a quasi-experimental design with a pretest, midtest, and posttest structure. Eighteen elderly male participants, with a mean age of 65.38 years, were randomly assigned to either an experimental group or a control group. Reaction time was measured using a YB-1000 reaction timer. The experimental group underwent 12 sessions of neurofeedback training, conducted three times per week for 30 minutes each. The protocol focused on increasing beta wave power and decreasing theta wave power, recorded via electrodes placed at the O2-O1 sites in the occipital region. To control for placebo effects and empathy, the control group attended an equal number of sessions but only observed recorded brain waves from the experimental group rather than receiving active feedback based on their own neural activity. Statistical analysis using Multivariate Analysis of Covariance (MANCOVA) revealed significant improvements in the reaction time of the experimental group compared to the control group. Specifically, significant differences were observed after six sessions (midtest, P=0.004) and after the completion of all 12 sessions (posttest, P=0.001). The experimental group demonstrated a marked reduction in reaction time, whereas the control group showed no significant improvement. Post-hoc tests confirmed that the experimental group outperformed the control group in both midtest and posttest measurements. The findings conclude that neurofeedback training is an effective method for enhancing cognitive processes, particularly reaction time, in elderly males. By reinforcing beta waves and inhibiting theta waves, the training facilitates better self-regulation of brain activity and improves memory utilization. The study suggests that neurofeedback can serve as a valuable non-pharmacological intervention to counteract age-related declines in cognitive speed and executive control, potentially improving the quality of life and functional independence of the elderly population.
