Eucidation of audio-visual dominance for the memory of the idiom-string

Abstract

The concept of audio-visual dominance is whether vision or auditory is superior in the specific situation. Generally, the dominance in memory task were examined whether visual memory or audio one is more accurate in memory formation. The conventional studies examined accuracy of memory with stimuli to only the visual sense or to the auditory sense. In this study, we examined the predominance of audio- visual dominance in memory task in case that both of them are stimulated simultaneously in memory- formation-task, and EEG was measured during the experiments to examine the relationship between accuracy of the memory and objective brain activity. We found visual dominance in the experiments with only visualor with only auditory stimulation . However, results of experimentssimultaneous with both of visual and auditory stimulation showed auditory dominance. Focusing on EEG characterisics, θ waves considered to be expressed with concentraed situation tended to be observed in the visual-related and auditory-related areas than in normal stateThis tendency was more remarkable in the memory task in English than in Japanese for Japanese-native experimental particiants.
