Lorenz described the baby schema ( Kindchenschema ) as a set of infantile physical features such as the large head, round face, high and protruding forehead, big eyes, chubby cheeks, small nose and mouth. Previous work on this fundamental concept was restricted to positive perception to infant face, and did not show consistent results about the development individuals perceptions, regarding the physical attributes that worked as markers of cuteness. Here, we experimentally tested the effects of baby schema on the perception of cuteness of infant faces by children and adults. We used 60 none graphically manipulated photos of different stimulus children faces from 4 to 9 years old. In the first task for the adults experimental subjects, ten stimulus photos were shown, whereas for children experimental subjects, four stimulus photos were shown at a time, with a total of six rounds. The second task involved only adults, who indicated the motivation of affective behaviors and care directed to children through a Likert scale. Our results suggest that both participants judged similarly the cuteness of children's faces, and the physical features markers of this perception were observed only for younger stimulus children. Adults have attributed more motivations of positive behaviors to cuter stimulus children. The recognition of the baby schema by individuals of different ages and genders confers the universality and power of children's physical attributes. From the evolutionary perspective the responsiveness to baby schema is significant to ensure aloparental and parental investment, and the consequent children survival / As informa??es da face infantil evocam aten??o, comportamentos de cuidado parental e modulam as intera??es entre adultos e crian?as. Lorenz descreveu o esquema infantil ( Kindchenschema ) como um conjunto de caracter?sticas f?sicas da face, tais como: grande cabe?a, face arredondada, testa proeminente e alta, olhos grandes, bochechas arredondadas e salientes, e nariz e boca pequenos. Trabalhos pr?vios tiveram uma concep??o fundamental restrita as percep??es positivas ?s faces infantis, e n?o apresentaram resultados consistentes sobre o desenvolvimento da percep??o dos indiv?duos quanto aos atributos f?sicos que funcionavam como marcadores de fofura. N?s testamos experimentalmente o efeito do esquema infantil sobre a percep??o de fofura das faces infantis por adultos e crian?as. Para isso, utilizamos 60 fotos das faces n?o manipuladas graficamente de diferentes crian?as-est?mulo de 4 a 9 anos de idade. Para isso, utilizamos 60 fotos das faces n?o manipuladas graficamente de diferentes crian?as-est?mulo de 4 a 9 anos de idade. Na primeira tarefa para os sujeitos experimentais adultos eram mostrados dez fotos-est?mulo e para os sujeitos experimentais crian?as quatro fotos-est?mulo por vez, num total de seis rodadas. Na segunda tarefa participaram apenas os adultos, que por meio de uma escala likert indicavam a motiva??o de comportamentos afetivos e de cuidado direcionado para as crian?as. Nossos resultados apontam que ambos os participantes julgaram de forma similar a fofura das faces infantis, e as caracter?sticas f?sicas marcadoras dessa percep??o foi verificada apenas para as crian?as-est?mulo mais novas. Os adultos atribu?ram maiores motiva??es de comportamentos positivos as crian?as-est?mulo mais fofas. O reconhecimento do esquema infantil por indiv?duos de diferentes idades e g?neros confere a universalidade e pot?ncia dos atributos f?sicos infantis. Sob a perspectiva evolutiva a responsividade ao esquema infantil ? significante por assegurar investimento parental e aloparental, e a consequente sobreviv?ncia das crian?as
