This study performs Electroencephalogram (EEG), one of the emerging brain science research
methods, on young children to explore the difference in their emotional stability and stress in
response to different visual stimuli. Research was carried out on the subject of 33 young children at
5 year old age, by first, measuring resting EEG using measurement equipment (QEEG-4 System),
then exposing two types of visual stimuli (Calming Video Clip, Active Video Clip), and finally
measuring EEG responsible for emotional stability and stress of each children. The results of the
study are as follows: (1) Stability index was more active in resting EEG, compared to EEG after
exposure to Calming Video Clip, and EEG after exposure to Active Video Clip in that order, and
there are significant differences between three classes of stimuli. (2) Stress Indexes are more active in
EEG after exposure to Active Video Clip, compared to EEG after exposure to Calming Video Clip,
and resting EEG in that order and there are significant differences between three classes of stimuli.
By examining potential influence of various audiovisual stimuli prevalent in young children’s everyday
life, this research attempts to caution against overuse of visual media, and, at the same time, hopes
to promote access and utilization of more scientific research methods on the field of young children
education research.
