Dataset of 'Visual adaptation to extreme-sized bodies induces persistent distortion of body size perception'

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.
