“…Newborn girls were more sensitive to being uncovered (Bell & Costello, 1964), and at 2-weeks they reacted more sensitively to skin-to-skin contact than boys (Wolff, 1969). Newborn girls were also more sensitive to sweet taste and consumed more milk if it was sweetened (Nisbett & Gurwitz, 1970). In conclusion, of the few studies published, behavioural differences between newborn girls and boys have been observed, albeit some of the results are inconsistent and most of the studies were not designed to explore sex-differences (Korner, 1974).…”

Socio-emotional behaviour is in part sex-related in humans, although the contribution of the biological and socio-cultural factors is not yet known. This study explores sex-related differences during the earliest communicative exchange, the neonatal imitation in 43 newborn infants (3-96 hours old) using an index finger extension imitative gesture. Results showed that although the experimenter presented comparable stimuli to both sexes, and the total number of movements was similar in boys and girls, girls showed more fine motor movements, a higher number of specific imitative gestures, responded faster during the imitation and showed a higher baseline heart rate during the experiment. Newborn girls, with their faster and more accurate imitative abilities, may create a more responsive and interactive social environment, which in turn may lead to differences in socio-emotional and cognitive development between girls and boys.

“…From the day they are born, infants demonstrably prefer sweet tastes and avoid bitter and sour tastes (Nisbett and Gurwitz, 1970;Desor et al, 1973;Desor et al, 1975;Steiner, 1977), and by four months of age a preference for salt reliably develops (Beauchamp et al, 1994). These "four basic tastes" have a well-known physiological basis, with receptor cells in the tongue responding to the presence of specific classes of chemicals (simple carbohydrates, many structurally unrelated compounds, acids, and sodium, respectively) by stimulating tastespecific neural pathways and brain regions (Carlson, 2002, pp.…”

“…One century after these keen observations were made, the scientific investigation of taste preferences during human ontogeny began. This body of research has focused primarily, but not exclusively, on sweet tastes and has repeatedly demonstrated, as Darwin noted, the strong acceptance of sweet-tasting sugars during infancy and childhood (Desor, Green, & Maller, 1975a;Enns & Itallie, 1979;Maller & Desor, 1973;Nisbett & Gurwitz, 1970;Peiper, 1961Peiper, /1963Steiner, 1977), with preference levels decreasing to resemble that of the adult during late adolescence (Desor & Beauchamp, 1987).…”

We investigated the effects of early experience on sweet and sour preferences in children. Eightythree children were divided into four groups based on the type of formula fed during infancy and age. By using a forced-choice, sip-and-swallow procedure, we determined the level of sweetness and sourness preferred in juice. Children who were fed protein hydrolysate formulas, which have a distinctive sour and bitter taste and unpleasant odor, preferred higher levels of citric acid in juice when compared to older children who were fed similar formulas. No such difference was observed between the groups for sweet preference. However, the level of sweetness preferred in juice was related to the sugar content of the child's favorite cereal and whether the mother routinely added sugar to their foods. These data illustrate the wide variety of experiential factors that can influence flavor preferences during childhood.
