A hair whorl is a patch of hair growing in a circular direction around a visible center point. Hair whorls occur in most hairy animals, on the body as well as on the head. Hair whorls, also known as crowns, swirls, or trichoglyphs, can be either clockwise or counterclockwise in direction of growth. Hair whorls on the head parietal whorls have been studied by some behaviorists. Most people have clockwise scalp hair-whorls.
Among these are: finger-length ratios the ratio of index finger length to ring finger length , handedness whether a person is right or non-right-handed , hair whorl patterns whether a man has a clockwise or counterclockwise hair whorl , interests the degree to which a person is interested in masculine vs. The following sections briefly summarize recent scientific research on these topics and list selected references to published studies. The six participants in the Tyra Banks Show were selected by the show's staff, and the "sample size" was very small. Actual scientific studies would have assessed larger and more diverse groups of people and they would have tested them under more controlled circumstances.
Spatial Judgment Research suggests early exposure to hormones, such as testosterone, in the womb contributes to this ability. Higher levels of testosterone are associated with a shorter index finger relative to the ring finger. Why would birth order be a factor? While there have been no studies to conclusively say what determines sexual orientation, it is widely accepted in the scientific community that genetic and developmental factors both play a role. When did they decide to be gay?
Ortiz simply cannot hit those sizzling left-handed fast balls for which Johnson, a five-time Cy Young Award winner, is famous. Baseball lore has it that left-handed batters have more trouble hitting off left-handed pitchers than right-handed batters do against right-handed pitchers. Adding greatly to the interest are reports that three times as many left-handed people have schizophrenia, bipolar disease manic-depressive illness , or autism as would be expected from the prevalence of left-handedness in the population at large.
