Marching through the claims like Sherman through Georgia

Neuroscientist Lise Eliot finds that claims of sex differences fall apart. In one study, scientists dressed newborns in gender-neutral clothes and misled adults about their sex. The adults described the "boys" (actually girls) as angry or distressed more often than did adults who thought they were observing girls, and described the "girls" (actually boys) as happy and socially engaged more than adults who knew the babies were boys. Dozens of such disguised-gender experiments have shown that adults perceive baby boys and girls differently, seeing identical behavior through a gender-tinted lens. "Eliot immersed herself in hundreds of scientific papers (her bibliography runs 46 pages). Marching through the claims like Sherman through Georgia, she explains that assertions of innate sex differences in the brain are either "blatantly false," "cherry-picked from single studies," or "extrapolated from rodent research" without being confirmed in people. For instance, the idea that the band of fibers connecting the right and left brain is larger in women, supposedly supporting their more "holistic" thinking, is based on a single 1982 study of only 14 brains. Fifty other studies, taken together, found no such sex difference—not in adults, not in newborns. Other baseless claims: that women are hard-wired to read faces and tone of voice, to defuse conflict, and to form deep friendships; and that "girls' brains are wired for communication and boys' for aggression." Eliot's inescapable conclusion: there is "little solid evidence of sex differences in children's brains.""

test your your brain

Test My Brain was set up by Harvard's Vision Lab and Social Neuroscience and Psychopathology Lab. There are five tests online at the time of this post; take one and maybe you'll learn something about yourself that you may not have known (other than your special ability to slack off on MetaFilter when you should be working). At the same time, you'll be helping researchers collect data from a wide range of subjects. One of the collaborators, Professor Ken Nakayama, is also responsible for creating these online tests for faceblindness. [previously] [Disclaimer: I work at Harvard, but not in the same department; I know none of the collaborators.]

A team of researchers at the ATR Computational Neuroscience Laboratories in Kyoto have managed to reconstruct black-and-white visual images from an fMRI scan of a test subject's brain. Some more examples of the recovered data. The organization responsible claims that the technology to record thoughts and dreams is just around the corner. The paper, "Visual Image Reconstruction from Human Brain Activity using a Combination of Multiscale Local Image Decoders", is the cover article of the December 10 issue of the journal Neuron. [via]

Recent neuroscience research suggests that Democrats and Republicans are not nearly as far apart as they seem (NYT). Will an awareness that we are conning ourselves to feel alienated from each other help to close the political gap? Or, are we conned by science and the media?
