“…In fullterm and in preterm neonates * Morlet et al [1995a] found SOAE prevalence to be higher in female than in male subjects. Similar results were observed when testing preterm neonates only [* Morlet et al, 1995b], with a SOAE prevalence of 93% in female and 75% in male subjects. In newborns *Collet et al [1993] and in infants Strickland et al [1985] and Burns et al [1992] could confirm the gender difference, whereas *Kok et al [1993] found no definite correlation between SOAE prevalence and gender in newborns.…”

“…This observation corresponded to a significant interaction term between gender and ear side. * Morlet et al [1995b] found in preterm neonates a SOAE prevalence of 79% for the right ear and 72% for the left ear, whereas the investigation of * Khalfa et al [1997] showed a significantly higher prevalence in right ears. The study by revealed no dependence of SOAE prevalence on ear side in newborns.…”

“…In children up to 1 year, no significant age effect could be revealed. * Morlet et al [1995b] detected a mean number per ear of 6.1 in preterm neonates, and of 5.8 in preterm and fullterm neonates [Morlet et al, 1995a]. In healthy newborns * Kok et al [1993] found on average 5.5 SOAE per ear.…”

We investigated 267 infants and children aged 9 days to 16.8 years to study the spontaneous otoacoustic emission (SOAE) data prevalence, number per ear, level and frequency as a function of growth. Dependence on age, gender and ear side was statistically analyzed using the method of generalized estimation equations. Except in the 1st year of life, SOAE prevalence per ear and SOAE number per ear decreased significantly with increasing age. Both SOAE parameters were significantly higher in female than in male subjects, with gender difference of SOAE prevalence per ear being more distinct in the 1st year of life. Although a clear ear side effect on SOAE prevalence per ear could already be seen in ears of female children in this age group, only SOAE number per ear was significantly higher in right ears than in left ears from the 1st year of life on. Except in the first 12 months, SOAE level and SOAE frequency decreased significantly with increasing age. Neither a significant gender difference nor a significant ear side difference could be determined. Our results found in infancy and childhood are discussed within the framework of the current literature.

“…In preterm neonates, SOAEs can be recorded at 30 weeks of gestation [212], and they are comparable to full-term neonates in prevalence, peak number and acoustic frequencies. But, OAEs in preterm neonates do not show typical effects of laterality (more SOAEs in right than left ears) or sex (more SOAEs in females than males), suggesting that a substantial part of the maturation of the peripheral auditory system occurs around birth [212,213]. Overall, then, the current evidence makes it difficult to use OAEs as a measure of prenatal androgen exposure, although its promise should be explored, especially because it is unlikely that OAEs are influenced by aspects of the sex-typed social environment.…”

There is now good evidence that human sex-typed behavior is influenced by sex hormones that are present during prenatal development, confirming studies in other mammalian species. Most of the evidence comes from clinical populations, in which prenatal hormone exposure is atypical for a person's sex, but there is increasing evidence from the normal population for the importance of prenatal hormones. In this paper, we briefly review the evidence, focusing attention on the methods used to study behavioral effects of prenatal hormones. We discuss the promises and pitfalls of various types of studies, including those using clinical populations (concentrating on those most commonly studied, congenital adrenal hyperplasia, androgen insensitivity syndrome, ablatio penis, and cloacal exstrophy), direct measures of hormones in the general population (assayed through umbilical cord blood, amniotic fluid, and maternal serum during pregnancy), and indirect measures of hormones in the general population (inferred from intrauterine position and biomarkers such as otoacoustic emissions, finger length ratios, and dermatoglyphic asymmetries). We conclude with suggestions for interpreting and conducting studies of the behavioral effects of prenatal hormones. q

“…Watson (1969) found that female babies 12-14 weeks of age were more aroused by an auditory stimulus than were male babies of the same age exposed to the same stimulus. Morlet et al (1995) showed that the peripheral auditory system in the human female infant is significantly more advanced in development than in the male infant.…”

Reclaiming kindergarten: Making kindergarten less harmful to boys.

The kindergarten curriculum has undergone fundamental change over the past 50 years. The shift in curriculum in favor of reading preparedness has had the effect of emphasizing boys' weaknesses and girls' strengths. Two changes are proposed. First, alternative kindergartens emphasizing group activities and nonverbal skills must be established. Second, boys must be encouraged to enter such a kindergarten when they turn 5 years old. After 1 year of alternative kindergarten, the boy would enter contemporary kindergarten at age 6. Girls would continue to enter kindergarten at age 5. Most boys would therefore enter first grade at age 7, most girls at age 6. Substantial evidence suggests that such a change would have many benefits, particularly for boys. Adults think it wise to focus children's education on what adults need to know, without considering what children are in a position to learn. . . . You should begin, rather, by studying your pupils more carefully.
