Ena Onishi, a researcher from Kyoto University, observed captive chimpanzees displaying a tendency to urinate simultaneously, paralleling human social behaviors of going to the bathroom together. After extensive observation, Onishi's study indicated that chimp urination can be slightly contagious, influenced by proximity and social rank. While proximity increased the likelihood of one chimp urinating after observing another, this behavior was observed in only about 10% of instances. The study contributes to understanding social behaviors in chimpanzees, though the mechanisms behind this contagion remain unclear.
"This is a very interesting paper. I think that they demonstrate that urination is socially influenced in the chimpanzees that they studied." - Andrew Gallup
"Chimps who observed other chimps urinating were slightly more likely to go themselves, with proximity playing a key role." - Ena Onishi
"Urination makes a sound, and sometimes it was easier to hear the chimps going than to see them." - Ena Onishi
"Only about 10% of urination events appeared to be caught from other chimps within arms reach, indicating limited contagious behavior." - Ena Onishi
