    HANOVER, N.H. - A new Dartmouth study reveals that interracial contact has
    a profound impact on a person's attention and performance. The researchers
    found new evidence using brain imaging that white individuals attempt to
    control racial bias when exposed to black individuals, and that this act
    of suppressing bias exhausts mental resources.

    Published in the online edition of Nature Neuroscience on Nov. 16, the
    study combines the use of functional magnetic resonance imaging (fMRI),
    which measures brain activity, with other behavioral tests common to
    research in social and cognitive psychology to determine how white
    individuals respond to black individuals.

    "We were surprised to find that brain activity in response to faces of
    black individuals predicted how research participants performed on
    cognitive tasks after actual interracial interactions," says Jennifer
    Richeson, Assistant Professor of Psychological and Brain Sciences, the
    lead author on the paper. "To my knowledge, this is the first study to use
    brain imaging data in tandem with more standard behavioral data to test a
    social psychological theory."

    Their findings suggest that harboring racial bias, however unintentional,
    makes negotiating interracial interactions more cognitively demanding.
    Similar to the depletion of a muscle after intensive exercise, the data
    suggest that the demands of the interracial interaction result in reduced
    capacity to engage in subsequent cognitive tasks, say the researchers.

    For the study, thirty white individuals were measured for racial bias,
    which involved a computer test to record the ease with which individuals
    associate white American and black American racial groups with positive
    and negative concepts. Racial bias is measured by a pattern in which
    individuals take longer to associate the white Americans with negative
    concepts and black Americans with positive concepts. The study
    participants then interacted with either a black or a white individual,
    and afterward they were asked to complete an unrelated cognitive task in
    which they had to inhibit instinctual responses. In a separate fMRI
    session, these individuals were presented with photographs of unfamiliar
    black male and white male faces, and the activity of brain regions thought
    to be critical to cognitive control was assessed.

    "We found that white people with higher scores on the racial bias measure
    experienced greater neural activity in response to the photographs of
    black males," says Richeson. "This heightened activity was in the right
    dorsolateral prefrontal cortex, an area in the front of the brain that has
    been linked to the control of thoughts and behaviors. Plus, these same
    individuals performed worse on the cognitive test after an actual
    interaction with a black male, suggesting that they may have been depleted
    of the necessary resources to complete the task."

    According to Richeson, most people find it unacceptable to behave in
    prejudiced ways during interracial interactions and make an effort to
    avoid doing so, regardless of their level of racial bias. A different
    research project by Richeson and her colleagues suggested that these
    efforts could leave individuals temporarily depleted of the resources
    needed to perform optimally on certain cognitive tasks. This new study by
    Richeson provides striking evidence that supports the idea that
    interracial contact temporarily impairs cognitive task performance.

    These results suggest, according to the researchers, that harboring racial
    bias in an increasingly diverse society may be bad for one's cognitive
    performance.

    Other authors on the paper include Abigail A. Baird, Assistant Professor
    of Psychological and Brain Sciences; Heather Gordon, Ph.D. student in
    Psychological and Brain Sciences; Todd F. Heatherton, the Champion
    International Professor of Psychological and Brain Sciences and Director
    of the Center for Social Brain Sciences at Dartmouth; Carrie Wyland, Ph.D.
    student in Psychological and Brain Sciences; Sophie Trawalter, Ph.D.
    student in Psychological and Brain Sciences; and J. Nicole Shelton,
    Assistant Professor of Psychology at Princeton University.

    Rockefeller Center at Dartmouth College.

    In other words, diversity makes whites dumb.

    Now that's news you can use.

    diversity is reversed division, nothing more than a tool of social control

    So the mere existence of black people makes white people stupid? I guess that means blacks are the master race.:eusa_whistle:

    In other words being RACIST makes PEOPLE DUMBER.

    I think most of us already knew that.

    Or maybe we just assumed that racists were dumber than most people to begin with.

    Sounds like a grand reason to stop thinking like a racist to me.

    come to think of it, i have noticed a tendency towards general idiocy among racist people that i've met. they often display stupidity on a number of issues unrelated to racism.

    i once was sitting with some people at a restaurant and horrifically discovered that one of them was racist. there was a black family sitting a few tables down, and the racist who was sitting with us went into an emotional tirade and couldn't finish his meal properly. his whole meal went to waste.
