디지털 매체의 인지적 특성 연구: 뇌파검사(EEG)를 중심으로 = A Study on the Cognitive Characteristics of Digital Media on Brain-Activity Responses of Electroencephalogram(EEG)

다국어 초록 (Multilingual Abstract)

The purpose of this study is to examine and discover the cognitive characeristics of digital media on brain responses of EEG. Brain-Activity responses were measured on 8 electrodes(Fp1, Fp2, F3, F4, T3, T4, P3, P4) according to the international 10-20 electrodes system to 30 sampled university students using QEEG while the subjects were viewing the indentical content on analogue TV vs digital PC, and reading an identical article on Newspaper vs PC. The level of Brain activities were standardized with band to band power. The data were analysed by SPSSWin 12.0 with comparison t-test, independent group t-test and pearson correlation analysis. The results show that there were much differences in brain activity patterns while the subjects were viewing an identical content on TV vs PC and reading an article on newspaper vs PC. In general, digital media produces less brain activities and attentions compare to analogue media for the subjects. These may be that because of subject`s experience and biology he/her is better and more comfortable in viewing or reading digital media. Media behaviors of the subjects (heavy user/light user) could also affect their information processing for other media.
