摘要：Various factors are believed to cause blinking. One of these factors is attention. However, the relationship between blinking and attention has not yet been elucidated. In this study, we focus on electrodermal activity (EDA) to demonstrate this relationship. EDA is an electrical phenomenon involving the glandular releasing of sweat that is caused by mental excitement or strain. We employ EDA to quantify attention as a means to elucidate the blinking–attention relationship. We conduct an experiment based on EDA and present the results to verify this relationship.

One study estimated attentiveness using an index from physiopsychology to ; prevent such accidents [1]. The study indicated that blinking activity changes according to ; psychological factors; moreover; the relationship between blinking and attention has been ; suggested [2; 3]. One advantage of measuring blinking is that it can be easily performed without ; physical contact by using tools such as video cameras [4; 5; 6 ]. ; In previous research; an experimenter presented the subject with a problem; blinking was ; measured when the subject focused on the problem and the relationship between attention and ; blinking was supposedly verified [7]. The verification was based on the premise that a subject ; focuses his/her attention by working on a problem. However; this method cannot remove ; influencing factors; such as subject motivation and will. In other words; a subject may not ; actually exert much attention; instead; the subject might work on a problem merely by inertia. In ; this case; the premise mentioned above is not substantiated. Therefore; to verify the relationship ; between attention and blinking; a method of objectively measuring attention is needed. ; We therefore focus on electrodermal activity (EDA); which is an electrical phenomenon of the ; glandular releasing of sweat that is caused by mental excitement or strain. In psychology; EDA is ; used as an index to measure affective degrees; such as stress; strain; and excitement [8; 9]. EDA ; has been shown to have a meaningful relationship with attention [10]. In this study; we use EDA ; as a means of objectively measuring attention to elucidate the relationship between attention and ; blinking. We herein describe the experiment we conducted based on EDA and the results that ; verify this relationship.
