Evaluation of the effects of food intake on task engagement based on psychophysiological states

Abstract

The objective of this study was to evaluate the effects of food intake on performance and task engagement based on psychophysiological states. The experiment was conducted under two conditions: taking a break with his eyes opened between the repeated tracking tasks (Control), and taking a break with food intake (Intake). We found the rate of deterioration of the distance between target pointer and the mouse cursor, a performance index, showed significant differences between the two conditions. Significant differences were also found between the two conditions in all assessment items of subjective feelings. Considering the hemodynamic parameters and nasal skin temperature responses, it was found that the approach to the second task was different in the two conditions. Therefore, due to food intake between repeated tasks, psychological responses such as “Awareness” and “Refreshment” were maintained. Hence, it was confirmed that food intake stimulated positive task engagement in the task and maintained performance.

A Model for Predicting the Physiological and Psychological State of Eating Based on Sensory Evaluation

“…Five subjective feelings, hemodynamic parameters, and EEGs were measured to assess physiological and psychological states. These biometric experiments were performed using the same systems, procedures, and conditions as those used in a previous study [11]. This study was approved by the Life Science Committee of the Department of Science and Engineering at Aoyama Gakuin University (approval number: M13-17).…”

“…In addition, when the MBP decreased, it was classified as no stress coping. In a previous study [11], stress-coping styles were used to assess differences in task engagement with and without food. The results showed that there was a difference in task engagement between those who ate and those who did not.…”
