Comparison of EEG Oscillations During Visual Memory Encoding and Recognition under Exposure to Mozart’s Sonata Music K448

Classical Mozart’s music may provide a benefit or drawback effect on memory performance. Hence, an experimental study was conducted to discover its influence on memorizing ability. The evaluation indicator based behavioral data is common and cannot describe the effect of stimulation on body responses. The recent work investigates the influence of Mozart’s Sonata K448 music on visual working memory. The indicators of behavioral data and brain activities were used to assess memory performance. The brain signal was recorded from 60 participants via an electroencephalography (EEG) machine of 10–20 electrode system placement during visual assessment encoding and recognition stages. The duration of the assessment was 120 seconds for each stage. The acquired EEG signal was pre-processed using a wavelet filter to remove contaminated undesired components. Then, it was decomposed into theta, alpha, beta, and gamma oscillations. The mean, maximum amplitude and relative power were obtained from each oscillation. The EEG features pattern elucidated that brain activity was higher in recognition than encoding stages. Listening to Mozart’s music during visual assessment increased certain features compared to the control condition. In remark, Mozart’s music positively influenced visual memory.
