영화클립을 이용한 눈깜빡임과 시각적 주의력과의 상관성 연구

Abstract

Generally, human eye blinks are closely associated with the cognitive state or visual attention such asattentional requirements on visual stimuli. These previous studies have reported that eye blinks are related to explicitvisual attention using blink rate, pattern and blink timing across subjects. However, these results have been obtainedin a well-controlled experimental settings. So, it would prove difficult to investigate human’s natural response in acontinuous and realistic situation. In our study, we measured the eye blink intervals while participants viewed a movieclip. And we analyzed the blink interval data for relationship between visual attention and eye blink intervals. 24 participantstook part in two experimental sessions, first session to measure the IEBI while viewing the movie clip andsecond session to conduct a memory performance test using a self-questionnaire, which were spaced 3 weeks apart. The results indicate significantly higher memory performance at long IEBI period than short IEBI period whilewatching a movie clip(t = 3.257, df = 17, p < 0.005, 2-tailed). In addition, memory performance score significantlycorrelated with the IEBI value(spearman’s rho = 0.40, N = 36, p < 0.01, 2-tailed). Our results suggest that IEBI isused to measure or assess visual attention while wiewing the movie that it is capable of simulating aspects of reallifeexperiences by visual attention. Thus, we expect IEBI to be used to measure or assess our visual attention, cognition,further emotion about not only movies, advertisements and other cultural contents but also cognitive science.
