Adaptation aftereffects for features such as identity and gender have been shown to transfer between faces and bodies, and faces and body parts, i.e. hands. However, no studies have investigated transfer of adaptation aftereffects between whole bodies and body parts. The present study investigated whether visual adaptation aftereffects transfer between hands and whole bodies in the context of adiposity judgements (i.e. how thin or fat a body is). On each trial, participants had to decide whether the body they saw was thinner or fatter than average. Participants performed the task before and after exposure to a thin/fat hand. Consistent with body adaptation studies, after exposure to a slim hand participants judged subsequently presented bodies to be fatter than after adaptation to a fat hand. These results suggest that there may be links between visual representations of body adiposity for whole bodies and body parts.
对于特征（如身份和性别）的适应后效已被证明可以在面部和身体之间，以及面部和身体部位（如手）之间转移。然而，尚无研究调查适应后效在整个身体和身体部位之间的转移。本研究调查了在肥胖判断（即身体是瘦还是胖）的背景下，手和整个身体之间的视觉适应后效是否会转移。在每次试验中，参与者必须判断他们看到的身体比平均体型更瘦还是更胖。参与者在接触瘦/胖手之前和之后执行任务。与身体适应研究一致，在手变瘦/变胖后，参与者判断随后呈现的身体比适应变胖的手后更胖。这些结果表明，整个身体和身体部位的身体肥胖的视觉表示之间可能存在联系。
