Abstract
Background Terminology working memory often used to describe the whole process of structure in memory, including executive function, which all information retains and uses in temporary period. Electroencephalography (EEG) is one of the tools in neuroscience research to investigate neuronal process in different condition, as well as working memory process. Results in this study hopefully provide baseline data for another neurofeedback research in cognitive process. Material & Methods Using the Muse, a portable low cost and wireless four-channel EEG headband, we record 27 students at 4th grade elementary school in Jatinangor. The brain waves δ and β bands are record while they get memory span task. The student will record in base 1, read 1, interphase1, recall 1, base 2, read 2 , interphase2, recall 2. Results and Discussion In this study, we report sex related changes δ and β trends bands in EEG power as peak frequency for both frontal and temporoparietal sites, in several condition task in working memory process. In female students increasing trends for δ and β in recalling process higher than male students. We discuss our finding probability sex related chages their attentional and emotional in working memory process.
