Peeing Is Socially Contagious In Chimps (404media.co) 55

After observing 20 chimpanzees for over 600 hours, researchers in Japan found that chimps are more likely to urinate after witnessing others do so. "[T]he team meticulously recorded the number and timing of 'urination events' along with the relative distances between 'the urinator and potential followers,'" writes 404 Media's Becky Ferreira. "The results revealed that urination is, in fact, socially contagious for chimps and that low-dominant individuals were especially likely to pee after watching others pee. Call it: pee-r pressure." The findings have been published in the journal Cell Biology. From the study: The decision to urinate involves a complex combination of both physiological and social considerations. However, the social dimensions of urination remain largely unexplored. More specifically, aligning urination in time (i.e. synchrony) and the triggering of urination by observing similar behavior in others (i.e. social contagion) are thought to occur in humans across different cultures (Figure S1A), and possibly also in non-human animals. However, neither has been scientifically quantified in any species.

Contagious urination, like other forms of behavioral and emotional state matching, may have important implications in establishing and maintaining social cohesion, in addition to potential roles in preparation for collective departure (i.e. voiding before long-distance travel) and territorial scent-marking (i.e. coordination of chemosensory signals). Here, we report socially contagious urination in chimpanzees, one of our closest relatives, as measured through all-occurrence recording of 20 captive chimpanzees across >600 hours. Our results suggest that socially contagious urination may be an overlooked, and potentially widespread, facet of social behavior.

In conclusion, we find that in captive chimpanzees the act of urination is socially contagious. Further, low-dominance individuals had higher rates of contagion. We found no evidence that this phenomenon is moderated by dyadic affiliation. It remains possible that latent individual factors associated with low dominance status (e.g. vigilance and attentional bias, stress levels, personality traits) might shape the contagion of urination, or alternatively that there are true dominance-driven effects. In any case, our results raise several new and important questions around contagious urination across species, from ethology to psychology to endocrinology. [...]

  • Here is a way to save a little money on this very important research: when a group of people walk past a toilet, some will need to go in and others may go in and actually use it as well, because it is a toilet on the way and since some are already using it, the time is already being spent, so why not?

    Next we need to investigate why people and chimps eat in groups, why they sleep at night, how come children are all required to study?

      We should just observe the fact that female logic has a distant cousin in nature.

      It’s gonna take a lot more than chimps pissing to crack that code.

        Probably one of human languages earliest oxymoron ;)

      As a person that gets curious about human behaviors and how much of them stem from some older, pre-modern necessities, I've often theorized that men were used to braving leaving the tribe alone for purposes of hunting, scouting, traveling between tribes for trade, and other purposes, so wouldn't think twice about heading out alone for bathroom necessities. Women were used to staying in the tribe, and since scavenger animals that may attack would stay gathered close to human settlements, if they headed to th

        My theory is, traditionally, donning tight-fitting clothes that women tend to wear, was a two person job. Plus, a mirror might not be available, requiring an ally to fix make-up and appearance. Now, males head to the toilet in groups. Sometimes it's middle-aged males, and it's a problem when a trio of 10 year-olds are loitering beside the cubicles. Which might be why the public pool raised the age of supervision to 12. That in turn, requires single-dads to take their daughter into the men's change-room

      Some of us are old enough to have actually talked to women. It turns out that once you get married they're quite willing to explain why they go to the bathroom in groups: "because we want to talk about the guys." That's straight from the source. You're welcome.

      Came here to say the same thing. Also, to wonder if this behaviour might be related to the "contagiousness" of yawning. And thence to wonder if psychopaths are immune to 'pee contagion', as they are to 'yawn contagion'.

        I was under the impression that yawns are contagious as an alertness mechanism, putting off sleep for the activity in progress, even guard duty or whatever.

        Laughter being somewhat opposite, a disarm flag, everyone expresses relief at an unresolved stimulus (rustling bushes reveal a rabbit not a tiger, or maybe even active tiger slain) being resolved and signals to trade adrenaline for relaxants. Humor being built atop the same resolution mechanism, an inconsistency (anomaly, threat) presents unexpectedly, i

      Hate to admit it, but I'm still LMAO as I write this.

  • I used to be confused why my dog kept trying to come into the bathroom when I had to pee, then I realized turnabout was fair play.
  • There's a pretty good chance they were "influenced."
  • Chimpanzees also fling poo.

  • That's a pisser.
