"It made a huge difference," said Sonia Duffy, the lead author of the report, which was published in The Archives of Pediatrics and Adolescent Medicine. "The kids expressed more confidence in the cartoons than in the warnings themselves."
Primal and widespread though the taste for cute may be, researchers say it varies in strength and significance across cultures and eras. They compare the cute response to the love of sugar: everybody has sweetness receptors on the tongue, but some people, and some countries, eat a lot more candy than others.
Japan's cute fixation
Experts point out that the cuteness craze is partic-ularly acute in Japan, where it goes by the name kawaii and has infiltrated the most masculine of redoubts. Truck drivers display Hello Kitty-style figurines on their dashboards. The police enliven safety billboards and wanted posters with two perky mouselike mascots, Pipo kun and Pipo chan.
Behind the kawaii phenomenon, according to Brian McVeigh, a scholar of East Asian studies at the University of Arizona, is the strongly hierarchical nature of Japanese culture. "Cuteness is used to soften up the vertical society," he said, "to soften power relations and present authority without being threatening."
In this country, the use of cute imagery is geared less toward blurring the line of command than toward celebrating America's favorite demo-graphic: the young. Dr. Orvell traces contem-porary cute chic to the 1960s, with its celebration of a perennial childhood, a refusal to dress in adult clothes, an inversion of adult values, a love of bright colors and bloopy, cartoony patterns, the Lava Lamp.
Young and gifted
Today, it's not enough for a company to use cute graphics in its advertisements. It must have a really cute name as well.
"Companies like Google and Yahoo leave no question in your mind about the youthfulness of their founders," said Dr. Orvell.
Madison Avenue may adapt its strategies for maximal tweaking of our inherent baby radar, but babies themselves, evolutionary scientists say, did not really evolve to be cute. Instead, most of their salient qualities stem from the demands of human anatomy and the human brain and became appealing to a potential caretaker's eye only because infants wouldn't survive otherwise.
Human babies have unusually large heads because humans have unusually large brains. Their heads are round because their brains continue to grow throughout the first months of life and the plates of the skull stay flexible and unfused to accommodate the development. Baby eyes and ears are situated comparatively far down the face and skull, and only later migrate upward in proportion to the development of bones in the cheek and jaw areas.
Baby eyes are also notably forward-facing, the binocular vision a likely legacy of our tree-dwelling ancestry, and all our favorite Disney characters also sport forward-facing eyes, including the ducks and mice, species that in reality have eyes on the sides of their heads.
The cartilage tissue in an infant's nose is comparatively soft and undeveloped, which is why most babies have button noses. Baby skin sits relatively loose on the body, rather than being taut, the better to stretch for growth spurts to come, said Paul Morris, an evolutionary scientist at the University of Portsmouth in England, that lax packaging accentuates the overall roundness of form.
