2023-08-05 Dataset of 'Visual adaptation to extreme-sized bodies induces persistent distortion of body size perception' doi:10.57760/sciencedb.psych.00141 en Body size misperception is a key symptom of eating disorders (ED). Recent studies have supported an emerging theory that the distorted body perception might be associated with adaptation in repeated visual exposures to extreme-sized bodies. However, it remains questionable whether the influence of body size adaptation is sustained enough to affect daily-life body size perception. Here we investigated the timescale of short-term and long-term body size adaptation on perceived body size and studied the underlying neural mechanisms using event-related potentials (ERPs). In two experiments, we demonstrated that adaptation to extremely thin or fat body stimuli would led to a sustained bias of shifting the perceived normal body size towards the adapting body shape. Moreover, repeated adaptation to extremely thin bodies enhanced the anti-fat bias in body processing. These findings provide new evidence for the idea that body size adaptation may be implicated in the development of ED. body image; body size adaptation ; timescale ; ERP ; anti-fat bias Xiaohui Sang Xue Dong Min Bao PUBLIC https://creativecommons.org/licenses/by-nc/4.0/ dataset Science Data Bank
