In order to examine the relative influence of size-based expectancies and social cues on the perceived weight of objects, two studies were performed, using equally weighing dolls differing in sex-related and age-related vulnerability or physical strength cues. To increase variation in perceived size, stimulus objects were viewed through optical lenses of varying reducing power. Different groups of participants were required to provide magnitude estimates of perceived size, physical strength, or weight, or of expected weight. A size-weight illusion (SWI) was demonstrated, such that smaller objects felt heavier than larger ones, that was entirely accounted for by the mediating role of expected weight. Yet, perceived physical strength exerted an additional and more reactive influence on perceived weight independently of measured expectancies. Results are used to clarify the nature of "embodied", internal sensory-motor representations of physical and social properties.
为了研究基于大小的预期和社会线索对物体感知重量的相对影响，我们进行了两项研究，使用了在与性别和年龄相关的脆弱性或体力线索方面存在差异但重量相等的玩偶。为了增加感知大小的变化，通过不同缩小倍率的光学镜片观察刺激物体。要求不同组的参与者对感知大小、体力或重量，或预期重量进行大小估计。结果表明存在大小-重量错觉（SWI），即较小的物体感觉比大的物体更重，这完全是由预期重量的中介作用导致的。然而，感知到的体力对感知重量产生了额外的、且更具反应性的影响，这种影响独立于测量的预期。研究结果用于阐明身体化的、关于物理和社会属性的内部感觉运动表征的本质。
