Ask Ray | Your recent book mentioned cuteness and made me wonder

Ray,

Your recent book on creating intelligence mentioned cuteness in passing, and it made me wonder: why are most baby animals so cute. Naked mole rat is a possible exception?

They can’t look cute so we become gaga, if not for we humans, then it has to be for the parents, and if cuteness is not an exclusively human concept, its origins must be way back in time — and possibly is common to all mammals?

Baby birds in a nest are not cute, even baby fish aren’t terribly cute, though they do have big eyes. So the neural circuits that pick up on cuteness must reside elsewhere than in the cortex?

Is this an old thought that I haven’t come across elsewhere?

Thanks,
Howard

Howard,

I have to agree with you that baby naked mole rats are an acquired taste, in terms of cuteness.

All mammals have a neocortex so they apparently have some ability to appreciate the visual appeal of their youthful offspring. It is probably the case, though, that baby rats are cuter to their parents than to humans.

Best,
Ray

NPR | “Agreed, baby pandas are cute but why?”

excerpt | “The big eyes in their black sockets, the round face, the pug nose, the way giant pandas tumble about like toddlers. There is considerable evidence that these things are what are known as innate releasers to our parenting instincts, says Dr. Coons, a New York University psychologist.

“In 2005, The Washington Post asked Stephan Hamann, a psychology professor at Emory University, to explain why humans think certain animals are cute. Hamann conducted studies using functional magnetic resonance imaging (fMRI) to measure tiny changes in brain activity.

“His studies found that cute pictures cause increased activity in the middle area of the orbital frontal cortex, located behind the bridge of the nose, and in the amygdala, the emotion-control center of the brain responsible for fear and arousal.

“According to Hamann, increased activity in the middle orbital cortex is usually associated with pleasure and positive emotion. Some evidence suggests the brain activity there is greater when the stimulus is neotenous, which is to say it has juvenile characteristics — a button nose, big eyes, a large wobbly head, chubby extremities or pudgy cheeks.

“Many researchers have concluded that cuteness, or baby schema, is an evolutionary adaptation that triggers nurturing responses from adults — allowing survival of the cutest, in Darwinian terms.”

Wikipedia | biophilia hypothesis

excerpt | The biophilia hypothesis includes human preferences toward things in nature, which, while refined through experience and culture, are hypothetically the product of biological evolution. For example, adult mammals (especially humans) are generally attracted to baby mammal faces and find them appealing across species.

The large eyes and small features of any young mammal face are far more appealing than those of the mature adults. The biophilia hypothesis suggests that the positive emotional response that adult mammals have toward baby mammals across species helps increase the survival rates of all mammals.

Wikipedia | cuteness

excerpt | Cuteness is a subjective term describing a type of attractiveness commonly associated with youth and appearance, as well as a scientific concept and analytical model in ethology, first introduced by Konrad Lorenz. Lorenz proposed the concept of baby schema (Kindchenschema), a set of facial and body features, that make a creature appear “cute” and activate (“release”) in others the motivation to care for it.

Cuteness may be ascribed to people as well as things that are regarded as attractive or charming. Konrad Lorenz suggests “caretaking behavior and affective orientation” towards infants as an innate mechanism, triggered by cute characteristics such as “chubby cheeks” and large eyes.
