简介
We tested the hypothesis that the right cerebral hemisphere contributes to the enhanced body image distortions seen in women when compared to men. Using classical psychophysics, 60 right-handed healthy participants (30 women) were briefly presented with size-distorted pictures of themselves, another person (an experimenter), and a non-corporal, familiar object (a coke bottle) to the central, right, and left visual field. Participants had to decide whether the presented stimulus was fatter or thinner than the real body/object, and thus compare the presented picture with the stored representation of the stimulus from memory. From these data we extracted the amount of image distortion at which participants judged the various stimuli to be veridical. We found that right visual field presentations (initial left hemisphere processing) revealed a general “fatter” bias, which was more evident for bodies than for objects …
