Which Of The Following Animals Shares A Distinct Conscientiousness Dimension With Humans?

A new study of convict chimpanzees concludes that the personality traits of chimpanzees are well-nigh identical to those of humans.

I asked psychologist Sam Gosling of the University of Texas at Austin what'south been learned from the study. Prof. Gosling didn't take part in this particular research, just, equally i of the first people to study personality in nonhuman animals, he has perhaps the best overview of personality in all kinds of animals, both human and nonhuman.

The authors of the new study, conducted at at the Yerkes National Primate Research Center, identified five basic personality factors that combine differently in each individual chimpanzee: Authorization, Conscientiousness, Extraversion, Agreeableness and Intellect. This echoes the well-known Big Five model of the human personality, also known as the Body of water model.

Michael Mount : What do you mean when y'all talk almost the various dimensions of personality?

Sam Gosling: When nosotros talk almost personality, we ask first how many personality dimensions there are. [Psychologist] Hans Eysenck once said there are three main dimensions to human being personality: the introversion-extraversion domain; the neuroticism domain; [and a psychoticism domain].

You may also have heard of the famous Myers-Briggs Type Indicator, which says that humans can vary forth each of 4 basic dimensions.

Virtually of the work in scientific psychology has settled on the idea that there are five dimensions – the Big Five or Body of water model: your level of Openness to feel; your level of Conscientiousness; of Extraversion; of Agreeableness; and of Neuroticism.

And then yous accept scores on all five dimensions, and you can be high, medium or low on each of these. And that'south what we mean by personality structure. Nosotros mean: How many dimensions are in that location? And how are they related to each other? The five primary dimensions are by and large unrelated to each other. And so if I know your level of openness, that doesn't mean I know anything at all about your level on whatever of the other four dimensions.

Grand.M. : So that makes for a very wide range of potential personality in any given person.

S.G.: Yes. And each of those dimensions is also very broad. When we talk well-nigh Extraversion, for example, this incorporates many other, narrower facets like your energy level, cheerfulness, gregariousness, talkativeness and authorisation – those sorts of things, they're all correlative, and so they all go to brand upwardly this broader domain of introversion-extraversion. And in general (simply non always) those things like talkativeness and gregariousness tend to become together.

The Big Five model measures your level of Openness to new experiences; your level of Conscientiousness; of Extraversion; of Agreeableness; and of Neuroticism.The Large Five model relates to wide patterns of thinking, feeling and behaving. Information technology doesn't include things like our values, our goals, our identity and and so on. If someone has a goal in life to achieve salvation or to get very wise, or they see themselves as wanting to save the world or whatsoever, that's not part of the Big Five. The Big Five is just looking at behavioral traits and cognitive and emotional patterns as indicators of your basic personality.

Personality in Other Animals

1000.M. : Some years agone, you started looking at other animals to see if you could begin to classify their personalities into particular dimensions, too?

Southward.Chiliad.: One of the early questions when we started was "Exercise other animals have personality?" And if so "What does that personality await like?"

So we began with the same questions: "How many dimensions do nonhuman animals accept, and what are those dimensions?"

Chiliad.M. : So when this new written report talks nearly chimpanzees having essentially the same personality traits as humans, does that mean they're looking at them on all of these same five dimensions?

South.G.: Yes, and more. Considering to say they have these five and any others, you have to search very broadly.

When I did my study of captive hyenas a long time ago, we plant they had 5 dimensions. There was some overlap in these with the homo Large V, but some points of discrepancy, besides. Virtually all species have something alike to the human extraversion and neuroticism dimensions.

And in another study that I wrote 15 years ago when I was just finishing graduate school, I tried to do a review of all the literature, proverb OK, where do we run across commonalities beyond species and where practise we not see commonalities? And if y'all look at almost all the piece of work that's looked at personality construction and you take them all together, what they show is that nigh all species have something akin to the human Extraversion dimension. Extraversion at a broader level can actually exist thought of equally individual differences in a trend to approach positive things.

Almost all species also have an analog of what would exist called in humans a Neuroticism dimension, and that would exist the tendency to be sensitive to threats and danger.

So in virtually all species, yous discover that they vary in their tendency to be sensitive to what can go right and be positive – things like food and mates, and foraging areas and territory and then on. And you detect tendencies to be sensitive to things that can go wrong – things that can consume you.

What you encounter is that unlike combinations of those are adaptive in unlike circumstances. So, for example, you'll notice that with fish who live in a stream where there are predators nowadays, it's adaptive for them to exist high on this dimension that's like Neuroticism because then yous will non go eaten, and you'll exist very sensitive to whether there are predators about. However in parts of the stream where there are non predators present, it's maladaptive to be loftier on this Neuroticism dimension considering you'll constantly be worrying about things that aren't there, so you won't be taking advantage of eating and mating possibilities because y'all're e'er on the lookout for these nonexistent dangers.

G.M. : Then, going dorsum then to the chimpanzee study.

S.G.: Well, when information technology comes to chimpanzees, there's actually been a lot of other work washed on this. Alex Weiss, for case, has been working on it for a long fourth dimension. He's been looking at apes and monkeys and he's been maxim that the bottom line is that chimpanzees seem to have all v of the human being dimensions.

The one place that chimpanzees and humans really differ from other species is that there hasn't been evidence of species other than humans and chimpanzees having the dimension of Conscientiousness. And that makes sense given what we know about the neural construction of conscientiousness, which is the avant-garde frontal lobe. Information technology'southward the ability to programme alee, to inhibit 1's impulses, and to put something off until afterward. That's really what the frontal lobe is most. And that very large frontal lobe is what'south different in humans from other animals. And chimpanzees take a pretty large frontal lobe compared to other animals, besides.

M.M. : So, we might detect the same thing in a few other animals, as well, when we study their brains? Like you might come across information technology in, say, elephants and some of the cetaceans if they have large frontal lobes? Only that from what nosotros know, yous're not going to find the Conscientiousness dimension in your cat at home?

S.1000.: Probably. It turns out, though – and this is a complication –, that at that place's something a bit dissimilar in cats and dogs. And that might be considering we humans take put such loftier selection pressure level on them that if we're going to have creatures who live with us, there's unusually large selection force per unit area for ones that are not going to do things that nosotros don't await. So I think dogs and cats are probably a fleck dissimilar other kinds of animals because of that specific selection pressure level. And that selection force per unit area is much stronger – it's bogus, merely as we might select cows to have a loftier meat yield and be very docile.

1000.One thousand. : O.K., so dorsum once more to the chimpanzees.

S.G.: Yes, and one thing that Alex Weiss has shown for a long time is that they take this Potency dimension, too, which is somewhat singled-out. You don't find that one in humans, where physical dominance isn't so crucial anymore. With humans, it'southward more other forms of dominance that might determine who gets ahead and who doesn't. But the chimps have a very strong dominance dimension in addition to the Big 5.

Incidentally, hyenas take that Dominance dimension, too. They take a very strong social construction.

Yard.One thousand. : Any other things in chimpanzees that are different from humans?

S.Chiliad.: Mostly y'all'll encounter an analog of Extraversion and an analog of Neuroticism. Oftentimes yous'll meet a version of what in humans we call Agreeableness, simply in animals it's normally defined by the other pole: aggressiveness. And in other kinds of animals, Openness tends to be expressed in terms of curiosity and exploration and those sorts of things. But every bit you can imagine, that's also linked to things similar Extraversion because it's to practise with seeking new kinds of positive things.

K.Yard. : One of the things we're interested in when it comes to seeking recognition for chimpanzees and some other animals equally having certain fundamental legal rights, is being able to show that they're cognitively complex, self-aware and democratic.

S.Yard.: I don't know how [this particular kind of report] relates to the self-awareness upshot. I don't think it speaks to that directly. But [the Conscientiousness dimension] does speak indirectly to self-sensation. Similar, for case, in terms of the impulse to want to reach for the banana but to inhibit that impulse because I know at that place's another chimpanzee nearby and if I reach for the banana, so that chimp volition come across that I have a stack of bananas over here and will come and have them class me. And the idea of being able to programme and recollect ahead. Just I don't know what the relation to self-awareness is in that domain.

One thousand.M. : You've done quite a lot of piece of work with dogs, also. Dogs have the distinct dimensions of extraversion, conjuration and neuroticism.

Due south.M.: Nosotros've found that dogs have the distinct dimensions of Extraversion, Agreeableness and Neuroticism. But in dogs the dimensions of Openness and Conscientiousness seem to be fused together in a way. I call back that with dogs, because they're required to live in proximity to humans and also because we train them, in that location'southward this fusing of Conscientiousness and Openness to a dimension that we called Trainability. It may not be a very good proper noun for it, simply that's what we chosen it.

Do Any Animals Non Have a Personality?

1000.M. : Have you come up across any kinds of animals who don't prove personality?

Due south.G.: You know, it's like all of those other things we [humans] put out in that location to distinguish ourselves from other animals. Animals don't have them just as long as information technology takes until people get and accept a look and encounter if they have them. It's true of personality; it was true of emotions; it was truthful of thought; it was truthful of a moral sense. All of these things only last as long equally people don't look.

There's recently a study that came out about spiders. There's been work on fruit flies – they show individual differences, for example, in their tendency to get into fights or altercations with other fruit flies. You can test that by seeing if a fruit wing is more probable to become what we would telephone call aggressive with another fruit wing and to run into if they'll exercise that across time, like today and tomorrow and the side by side 24-hour interval, and beyond context, like if they'll do it in a mating context, a foraging context, so on. Virtually every species that'southward been looked at shows individual consistent differences in behavior. I would telephone call that personality traits.

So it's i of these things where about every species that's been looked at shows individual consistent differences in beliefs. Now, some people will say they don't desire to call that personality, only I would call it personality traits.

This has all really taken off in the terminal ten years since this work started to become pop in the field of fauna beliefs. So psychologists like me accept been working on it; primatologists have been working on it; and lots of people in applied ethology, working with farmed animals of diverse sorts.

K.M. : I guess they all take different reasons for these studies – and they're not always in the all-time interests of the animals!

S.One thousand.: Once the animal behavior people got into it, or the behavioral ecologists, they are interested in evolutionary processes. And the applied ethologists want to find cows and sheep and other animals who have the correct behavioral qualities for farming. And there's a subset of people now who are using this in the context of wild animals direction. They want to know, if we're going to reintroduce wolves to a new place, how tin nosotros apply personality to select which wolves get put into this park? And quite a lot of the people working in zoos are interested [in personality] in terms of which animals should be moved to a different zoo and which animals are going to make adept exhibits. If yous're running a zoo, you don't want
to prove an animal who'south likely to exist hiding backside a rock all the time.

M.Thousand. : That'due south not what it was all about when you first got into the field.

S.1000.: In fact, I'1000 get-go to get out of the whole field of animal personality at present. When I started doing it, there was really nothing there. But now, it's become such a big area that I tin can't even keep up with the literature. There's a publisher who's actually starting a whole journal on animal personality.

M.M. : Thanks for explaining information technology all, Sam.
