Biological function
Konrad Lorenz argued in 1949 that infantile features triggered nurturing responses in adults and that this was an evolutionary adaptation which helped ensure that adults cared for their children, ultimately securing the survival of the species. Some later scientific studies have provided further evidence for Lorenz's theory. For example, it has been shown that human adults react positively to infants who are

Gender differences

and behavior of the infant.
In the Koyama et al. (2006) research, female infants are seen as cute for the physical attraction that female infants display more than male infants;
whereas research by Karraker (1990) demonstrates that a caregiver's attention and involvement in the male infant's protection could be solely based on the perception of happiness and attractiveness of the child.
The gender of an observer can determine their perception of the difference in cuteness. In a study by Sprengelmeyer et al. (2009) it was suggested that women were more sensitive to small differences in cuteness than the same aged men. This suggests that reproductive

s in women are important for determining cuteness.
This finding has also been demonstrated in a study conducted by T.R. Alley in which he had 25 undergraduate students (consisting of 7 men and 18 women) rate cuteness of infants depending on different characteristics such as age, behavioral traits, and physical characteristics such as head shape, and facial feature configuration.
Preference in young children
Borgi et al. stated that young children demonstrate a preference for faces with a more "infantile facial" arrangement i.e. a rounder face, a higher forehead, bigger eyes, a smaller nose and a smaller mouth. In a study that used three- to six-year-old children, Borgi et al. (2014) asserted that the children showed a viewing time preference toward the eyes of "high infantile" faces of dogs, cats and humans as opposed to "low infantile" faces of those three species.
Hormones and cuteness variation
There are suggestions that hormone levels can affect a person's perception of cuteness. Konrad Lorenz suggests that "caretaking behaviour and affective orientation" towards infants as an innate mechanism, and this is triggered by cute characteristics such as "chubby cheeks" and large eyes. The Sprengelmeyer et al. (2009) study expands on this claim by manipulating baby pictures to test groups on their ability to detect differences in cuteness. The studies show that

s that raise levels of reproductive hormones detect cuteness better than same aged women not taking the pill.
Sprengelmeyer gathered 24 young women, 24 young men, and 24 older women to participate in his study. He ran three studies in which images of white European babies were shown, and the participants were asked to rate them on a cuteness scale of one to seven. The study found differences among the groups in cuteness discrimination, which ruled out

and social influences on perceived cuteness. In the second study it was found that premenopausal women discriminated cuteness at a higher level than their postmenopausal female peers. This finding suggested a biological factor, which was then investigated further in the third study. Here, Sprengelmeyer compared cuteness sensitivity between premenopausal women who were, and were not taking oral contraceptives. The study concluded that post-perceptual processes were impacted by hormone levels (

Caregiving correlates
A study by Konrad Lorenz in the early 1940s found that the shape of an infant's head positively correlated with adult caregiving and an increased perception of "cute". However a study by Thomas Alley found no such correlation and pointed out faulty procedures in that study. Alley's study found that cephalic head shape of an infant did induce a positive response from adults, and these children were considered to be more "cute". In his study, Alley had 25 undergraduate students rate line drawings of an infant's face. The same drawing was used each time, however the cephalic head shape was changed using a cardioidal transformation (a transformation that models cephalic growth in relation to ageing process) to adjust the perceived age; other features of the face were not changed. The study concluded that a large head shape increased perceived cuteness, which then elicited a positive response in adult caretaking. The study also noted that perceived cuteness was also dependent on other physical and behavioural characteristics of the child, including age.
In a study by McCabe (1984) of children whose ages ranged from toddlers to teenagers, the children with more "adult-like" facial proportions were more likely to have experienced physical abuse than children of the same age who had less "adult-like" facial proportions.
A study by Karraker (1990) suggested that "an adult's beliefs about the
personality

and expected behavior of an infant can influence the adult's interaction with the infant", and gave evidence that in this way "basic cuteness effects may occasionally be obscured in particular infants".
Koyama (2006) said that an adult caregiver's perception of an infant's cuteness can motivate the amount of care and protection the caregiver provides, and the admiration demonstrated toward the infant, and concluded that "the adults' protective feeling for children appeared to be a more important criterion for the judgment of a boy's cuteness."
Melanie Glocker (2009) provided experimental evidence that infants' cuteness motivates caretaking in adults, even if they are not related to the infant.
Glocker asked individuals to rate the level of cuteness of pictured infants and noted the motivation that these participants had to care for the infants. The research suggested that individuals' rating of the perceived cuteness of an infant corresponded to the level of motivation an individual had to care for this infant.
Glocker and colleagues then used

and rated as more "likeable, friendly, healthy and competent" than infants who were less cute. There is an implication that baby schema response is crucial to human development because it lays the foundation for caregiving and the relationship between child and caretaker.
