I’m reading a fascinating book called What’s Going on in There? : How the Brain and Mind Develop in the First Five Years of Life. It’s satisfying all of my obsessive need to know as much as possible about what’s happening, how we can make the baby healthier, happier, etc.
On page 82, I just ran across mention of a very strange study indeed:
One recent study, for instance, suggests that a child’s shyness is determined, in part, by maternal hormone fluctuations during gestation. Researchers who interviewed several thousand preschoolers in both the United States and New Zealand noted a significant relationship between the incidence of extreme shyness or inhibition (children who seem particularly fearful, anxious, or withdrawn in the presence of a stranger) and the amount of daylight their mothers were exposed to at midpregnancy. Thus, in the United States, only 12% of children born in October-November-December were rated as highly inhibited, compared to nearly 18% of those born in April-May-June. In New Zealand, where daylight hours are reversed, children showed the opposite pattern, with more shy children born in October-November-December than in April-May-June. Because the production of certain hormones, like melatonin, is known to fluctuate with the amount of daylight in each season, the researchers propose that such substances may subtly alter brain development during a critical period at midgestation, when massive numbers of neurons are migrating to form the basic architecture of the cerebral cortex. (It is also possible that other seasonal differences, like changes in women’s diets, physical activity, or exposure to colds and flu, mediate this relationship.)
Is this when science starts telling us that astrology is true? That would be pretty funny.
