  • Chocolate Craving

    Dedicated to the Sisters :D

    Chocolate craving feeds on imagery
    ----------------------------------------
    Good news for chocoholics. Psychologists at Flinders University in Australia have found a way to reduce chocolate craving that they hope might lead to an effective treatment.

    Forty-eight students were recruited, half of whom reported being a 'chocolate
    craver'. Chocolate cravers reported eating twice as much chocolate during the previous week as non-cravers.

    The students were shown photographs of different chocolate foods, including bars, cakes, ice cream and so on. Each photo was presented for five seconds in front of a computer screen. Sometimes the screen was blank, at other times it showed black and white fuzziness, known as 'dynamic visual noise'. Other times, the screen was blank but a recording was heard of a woman reading a Dutch newspaper article. After viewing each photo, the students had to stare at a blank screen and visualise the chocolate they'd just been shown. They then rated how vivid their chocolate image was and how intensely they were currently craving chocolate.

    For the chocolate-cravers only, more vivid chocolate images were correlated with moreintense chocolate craving. Crucially, across all the students, both chocolate imagery and craving were significantly reduced when the preceding chocolate photo was presented in front of a fuzzy computer screen, compared with a blank screen. This was true, but to a lesser extent, when the preceding photo was presented together with the Dutch recording.

    "According to working memory theory, dynamic visual noise reduces craving by interfering with food-related images held in the visual-spatial sketchpad" the authors said.

    You are not aware of the consequences that would result (if you were granted what you desire) because what you seek might be to your detriment. (O soul) be conscious that your Master is more aware about your well-being than you are.
