| Summary: | 碩士 === 東海大學 === 工業工程與經營資訊學系 === 96 === Brain is the control center of human body ,so that a trivial action such as blinking will lead to certain reactions to electroencephalography (EEG) in the brain. For instance, memory, concept and mental arithmetic are the results of how brain works. Moreover, reactions of brain differ from the level of difficulty. Due to this characteristic, we analyze the EEG data of participants during the experiment.
Our research is to investigate the reaction of EEG among memory, concept and the mental arithmetic complexity. The result shows that participants’ average EEG frequency under negative vision are greater than that under positive vision, which indicates that it is more difficult for participants to operate under negative vision. Also, under three different experiments of memory, concept and mental arithmetic complexity, the average frequency and amplitude of participants’ EEG toward vision, memory and thinking bigger than other electrodes .Moreover, we obtain the following conclusions:
1. The more complex the functions of frontal pole are, the greater the average frequency of brain (theta wave) will be, and vise versa.
2.The more frequent the participants’ hands moving, the greater the average average
frequency of Parietal will be, and vise versa.
3.The greater the vision stimulation is to participant, the greater the average frequency of Occipital will be.
4.The more visual complex of the experiment, the greater the average frequency of right brain theta wave will be.
