表面の状態と色が視覚と触覚による感情喚起に及ぼす影響

抄録

Effects of the conditions and colors of surfaces on pleasure-displeasure and arousal were examined. Stimuli were four plates with the combinations of two types of surfaces (smooth/slightly uneven) and two types of colors (white/black), which were presented under three conditions (visual/visual and tactile/tactile). Participants (N＝37) responded to the following six items using a seven-point scale: roughness, likes and dislikes, two items assessing pleasure-displeasure (tactile sensations, pleasantness), and two items assessing arousal (feelings of tension, clarity). The results indicated that evaluations of a surface differed based on the condition and color of the surface in roughness and pleasure-displeasure. Participants tended to judge white as smoother and more pleasant than black. Moreover, uneven surfaces tended to be affected by color. Furthermore, arousal was affected by stimulus presentation conditions and surface color. Also, smooth surfaces and black surfaces had high arousal levels. The results suggested that when roughness evoked by the color and the roughness of the surface was inconsistent (i.e., black smooth surfaces, white uneven surfaces), the arousal level might differ between under only tactile presenting condition and other two conditions.
