A Fundamental Study on Differences in Heart Rates During Creative Work and Non-creative Work

We sought to clarify how creative and non-creative work influence R-R intervals. Clearly different patterns of R-R intervals were found between creative and non-creative work, with heart rate quickening during creative work and recovering during subsequent rest periods. The differences between median R-R intervals during creative work were significantly and positively related to feelings of stress, with most coefficients of greater than 0.7 (reaching as high as 0.840; P < 0.001). In contrast, the differences between R-R intervals during non-creative work were not significantly correlated with feelings of stress, and the maximum coefficient did not exceed 0.3. Therefore, it appears that variability of median R-R intervals can be used to effectively predict feelings of stress when people engage in creative work but not when they engage in non-creative work.

Changes in Perception of Induced Motion Based on Voluntary Eye Movements in an Attentional Task

Sometimes a static object in video content is perceived to move. This motion illusion has been classified into two types: (1) induced motion and (2) motion capture. The purpose of this paper is to clarify how voluntary eye movements affect perceptions of induced motion and motion capture. By the results of a subjective assessment experiment, it is clarified that induced motion is inhibited by attention in both the horizontal and the vertical directions for reading textual information. It is also clarified that in contrast to induced motion, motion capture is not inhibited by attention. Specifically, motion capture is not inhibited by attention when viewers move their eyes in the same direction as the movement of the background.
