The present paper reports on an analysis of EEG signals to study the effect of audio-visual tasks and to see their effect on individual subjects using EEG Neurofeedback. Neurofeedback helps to alter the cognitive behavior. It could help in enhancement of the cognitive behavior of an individual in ways. This method of correlating the neurofeedback to that of the scores helps us draw parallel and prove that cognitive exercises can help increase the attention level of the individual. The dataset involved processing of two band wavelengths: Alpha (8-12 Hz) and Beta (12-22 Hz) to derive appropriate results and to analyze theoretical and practical level and to keep a track of appropriate changes that occur in the waveform. To ensure repeatability of results so as to enhance the performance of the subjects to increase attention level and practice the task, experiment protocol was finalized. Our experimentation and analysis show that the results of the experiment and numerical investigation have a good correlation to the analysis of EEG Data. This paper concludes with the remarks on the Alpha and Beta waves of the selected electrodes and the comparison between each subject to show that these tasks did have an overall positive effect. © 2006-2019 Asian Research Publishing Network (ARPN).
