| Outline of Final Research Achievements |
Contamination fear is characterized by overdetection of contamination source in the environment. This study investigated visual detection mechanisms of moisture, as a texture evoking disgusting emotion, using psychophysical experiments. Results indicated that participants could accurately evaluated the moisture content of the visually presented stimuli, and the evaluation was accurately predicted by number of high luminance areas distributed on the surface of the stimuli. In addition, among the texture related to moistness, slimy feeling (“Numeri” in Japanese) especially affected estimation of contamination risk caused by physical contact with the stimuli. Furthermore, only in highly disgust-sensitive participants, disgust emotion evoked by the stimuli strongly associated with individual differences in germ aversion. These findings suggested that we need to pay attention to both visual moisture detection process and the cognitive evaluation process to understand contamination fear.
