ITHACA, N.Y. -- Trying to cope with red flashing lights on green moving objects, the human visual system is tricked into revealing where yellow -- and all other colors -- apparently are composed: in the visual cortex of the brain. The red, green and blue cone receptors in the retina merely pass along signals for the brain to make sense of, Cornell University psychologist Romi Nijhawan concludes from an experiment that may confirm, once and for all, the "central synthesis" theory of human color vision.
ITHACA, N.Y. -- Although high school women are more concerned about their weight than men are about theirs, the women are more willing than men to date an overweight person. Once married, obese husbands are less happy with their marriages than other men, but men who have lost weight report fewer marital problems than obese or average-weight men or men who have gained weight during marriage. Obese wives, on the other hand, are happier with their marriages than average-weight wives. While newly-married women gain more weight than other wives do, or men do proportionately, few gain a lot during their first year of marriage. These are some of the recent findings of Jeffery Sobal, a Cornell nutritional sociologist who studies the sociology of obesity and the relationship between obesity and dating, marriage and marital satisfaction.
Researchers have long suspected that the chemistry of the brain largely influences personality and emotions. Now, a Cornell clinical psychologist has shown for the first time how the neurotransmitter dopamine affects one type of happiness, a personality trait and short-term, working memory.
William Julius Wilson was the opening speaker Oct. 19 at a symposium titled "American Society: Diversity and Consensus," honoring another heavyweight sociologist, Cornell's Robin M. Williams Jr., the Henry Scarborough Professor of Social Sciences Emeritus.
Researchers found that even a small increase in the number of women who have passed through that door to a managerial position dramatically increases other women's chances of being hired or promoted into that position. The result: a Catch-22 situation with important implications for the movement of women into management, as well as for the national affirmative action debate.
