Like i feel like languages diverge but like I feel like the worried/angry/happy facial expressions are universal. Are they? Am I right? why?
I know some gestures definitely aren’t. Nodding “yes” and shaking your head for “no” are not universal, nor is the “come here” motion or motions for eating or drinking.
One thing that IS universal is throwing your hands up in celebration of a victory. The thing boxers do at the end of a match. Even blind people who have never seen that gesture do it instinctively.
do you know why? that’s crazy
Isn’t laughing and smiling universal too?
Somewhat. In different cultures they can still mean different things but smiling and laughing from happiness and humour are universal afaik.
Paul Ekman had this “theory of basic emotions” that were supposedly universal for humans and had their set of “innate” gestures for each one.
For his original works, he travelled to some secluded communities and registered that the expressions for “happiness / fear / anger / disgust / sadness / surprise” were supposedly shared among human kind.
Why do I say supposedly? Because a lot of Ekman’s theory was disproved (for example, he claimed each emotion had an area of the brain dedicated to it, or at least some unique structure, which fMRI studies are not finding to be true, even if there is a lot we still don’t know on human emotion). There’s also claims that he contamined his data when he went to these secluded communities, and influenced (probably unknowingly) his results to make everyone’s expressions match the ones he expected for each emotion.So… are there universal expresions of emotion? Not an easy answer. The physical responses more linked to survival probably are (say fight/ flight in response to fear, startle in response to surprise). The more social ones? don’t know, some may be heavily influenced by culture. You would have to make a study on very young, blind babies from different cultures or something of the sort which would not be easy. Also there’s the thing that babies cannot tell you what emotion they are experimenting, even if you can asume some (loud noise and baby is crying probably equals fear, BUT the baby can’t confirm it, which is a methodological problem for some Scientists).
If this interests you, Ledoux has some great approachable work on the “survival circuits” of the brain that explain emotion in a way comparable to animals and linked to their evolutional value.
Sorry for the long ass answer. I happened to study this for a while.
Never apologize for sharing your knowledge.
Bro don’t apologize! The great thing about Reddit was that you would sometimes get experts on weird or niche subjects showing up to explain things in detail.
I remember reading that, during the Vietnam war, there were many issues when American soldiers would confront Vietnamese soldiers or citizens who would be smiling during the confrontation. The American soldiers took it as a sign that the Vietnamese were screwing with them somehow. It turned out that, for the Vietnamese, a nervous smile was very common.
Paul Ekman demonstrated back in the 1960s that, when showing photos of expressions to previously-uncontacted tribes in Papua New Guinea, these people who had no access to other media recognised and could name the feelings described. Also, blind children who have not been told what “a smile” is, will display the facial expression automatically. This research finding was one of the nails in the coffin of the Behaviourist school of psychology (with rats pulling levers) that said everything was learned by rewards/punishments.
Ekman identified 6 “basic” emotions: happy, sad, disgusted, angry, scared, and surprised (which, except for the last one, were the characters in Pixar’s “Inside Out”). Later researchers have proposed a seventh emotion of “pride”, which has the posture of puffed-out chest and smug half-smile, which again is displayed by blind athletes on winning competitions.
A little unrelated, but I remember hearing that going up at the end of a sentence when talking to a baby (doing a baby voice) is almost universal, but there’s one or two places on earth where that’s who you talk to people who are extremely senior or important. I think the one example cited was an island nation without much contact with the wider world.
Here’s a source (I think without the counter example): https://www.npr.org/2022/07/23/1113206642/baby-talk-parenting-language-research
Among humans, many seem to be somewhat universal. Across species, no - non-human primates (apes and monkeys), for example, may consider a smile a sign of aggression.
The most universal mammal behavior I know of is not visual, it’s the “hi I’m here” bark or grunt. It’s something that was pointed out in a wildlife tour video where they visited mountain gorillas: if you don’t make any noise and their first indication is visual, you may have predatory intentions, but if you add a little “mm” noise, you’re just passing through and they can relax.
It works for many kinds of creatures, humans included.
some of them are present in the mammal world, so I’d guess they are universal among humans, at least to a certain degree
One of the most mind opening things I ever read from Temple Grandin: to understand the difference between dogs and cats, you just have to notice that dogs have eyebrows and cats don’t.
I think it’s from her book Animals Make Us Human. She’s basically saying that dogs and cats have different needs when it comes to communicating with humans (and with each other), and dogs do a lot of it with facial expressions.
the hypothesis that dogs learned some expressions to communicate better with humans makes sense, but some expressions like showing the teeth to express disapproval is present in various mammal populations
