Analysis of Electroencephalography Signals on the Contents of Cognitive Function Game: Attention and Memory

摘要

In the current study, contents of cognitive function game were developed, and variations in Electroencephalography signals were measured and compared before performing the game tasks and during performing the game. The study sought to assess how much the game contents activated brain to see if they were suitable for cognitive functional training. For Electroencephalography signal analysis, power spectral analysis was implemented to classify signals according to frequency. To test signal variation according to the degree of brain activation before and after performing the game, variation comparison and paired f-test were conducted. Results showed that there was reduction in a wave signaling which implied that the subjects concentrate on the content, and increase in beta wave signifying that they were engaged in cognitive activities such as remembering and assessing. Consequentially, the produced contents in this study are expected to be useful for cognitive functional training.
