Abstract
It is supposed that many people use electronical device during intermissions as a communication tool. The purpose of this study is to revel the effects of behaviors during intermissions on performance and psychophysiological state. As behaviors during intermissions, text conversations with a smartphone were compared to oral conversations.
Twenty six healthy college students participated in this study. Tasks and fifteen-minute conversation during intermissions were performed. Subjective scores, electroencephalogram, electrocardiogram, and task scores were measured and evaluated.
As a result during conversations, heart rates and heart rate variabilities during oral conversations were higher than that during text conversations. Subjective scores of refreshment, relaxation, fulfillment, motivation, and concentration after oral conversations were higher than that after text conversations. There were no significant difference on task scores between two conditions.
Oral conversations as behaviors during intermissions activated physiological states and brought higher refreshment, compared to text conversations. It is expected that improved tasks reveals the effects of behaviors during intermissions on performance.
