ABSTRACT
Visual adaptation to certain body shapes alters visual perception of subsequently presented pictures of bodies. We investigated whether these effects can be explained by adaptation to low-level visual objects, ie narrow and wide rectangles. Participants (n = 29) adapted to manipulated photographs of their own bodies, depicting them either unrealistically thin or fat. The perceived shapes of their own bodies were subsequently assessed by an interleaved staircase paradigm. A second experiment (n = 29) used the same design to test for adaptation effects evoked by narrow and wide bars. After adapting to a thin picture of own body, participants also judged a thinner than actual body picture to be the most realistic and vice versa, resembling a typical aftereffect. Importantly, this effect could not be replicated by adaptation to narrow and wide bars, demonstrating that the body-shape aftereffect cannot be explained by adaptation to low-level properties. The results support the existence of a perceptual body-shape aftereffect, resulting from a specific adaptation to thin and fat body shapes.
