| Outline of Research at the Start |
The sight, smell, feel or sound of disgusting things can affect our ability to think clearly, but they may also provoke changes in our body, such as activating certain muscles of our face or decreasing our nasal temperatures. In this project, we will test whether this is also true for other great apes like chimpanzees. We previously observed behavioral responses by chimpanzees to disgusting things that resemble reactions of humans. We would like to go one step further now by investigating innate physiological responses, which could further highlight the origins of disgust in humans.

| Outline of Annual Research Achievements |
Overall, in collaboration with Professor Nobuyuki Kawai (Nagoya University), Ikuma Adachi, and Andre Goncalves (KUPRI), the JSPS fellow and I (the project PI) completed four experiments focusing on how (#1) visual and (#2) olfactory cues implying potential pathogen presence may impact cognitive performance, (#3) whether disgust-related images and fear-related images differ in terms of cognitive mechanisms, outcomes and (#4) number/duration of gazes received. FY2021 focused on completing lab work with chimpanzees at Kyoto University's Primate Research Institute and integrating the major results of each of the studies conducted. Preliminary results support the hypothesis that visual and olfactory cues indicative of pathogen presence decrease performance by distracting individuals, while the opposite effect is suggested for fear-related visual cues. The fellow presented this work at international conferences (Animal Behavior Society, CogSci2021), and is currently working toward production of manuscripts from this work to submit to international journals. The fellow and I (the PI) also published an invited paper in Frontiers in Ecology & Evolution on the correlation between contaminated food avoidance and protozoan infection in bonobos.
