  • Story:

    Stereograms appear to be composed entirely of
    random dots. However, they contain separate images that a
    viewer can “fuse” into a three-dimensional (3D) image by staring
    at the dots while defocusing the eyes. An experiment was
    performed to determine whether knowledge of the embedded
    image affected the time required for subjects to fuse the images.
    One group of subjects (group NV) received no information or
    just verbal information about the shape of the embedded object.
    A second group (group VV) received both verbal information
    and visual information (specifically, a drawing of the object).
    The experimenters measured how many seconds it took for the
    subject to report that he or she saw the 3D image.
