Preexposure disrupts learning of location-contingent perceptual biases for ambiguous stimuli.

abstract：:Lower order image statistics, which can be described by an image's Fourier energy content, enable segmentation when they are different on either side of a boundary. We have previously demonstrated that the spatial distribution of the energy in an image (described by its higher order statistics or structure) could infl...
