在3个实验中，我们研究了人加物体系统的孔径交叉的启示感知。知觉者挥舞着被遮挡的手持物体，并确定他们是否能够携带这些物体通过特定尺寸的孔径。结果表明：（a）当物体被挥动但不可见时以及当物体可见但未被挥动时，感知者对该示能表示敏感，（B）当携带物体时对孔径交叉的示能表示的感知受到约束手持挥动物体（I-ij）的范围感知的相同高阶惯性变量的约束，以及（c）当参与者的肩宽对人加物体系统的宽度有贡献时以及当参与者的肩宽对人加物体系统的宽度没有贡献时，感知者都对该示能表示敏感。一般来说，知觉者把挥动的物体看作是他们身体的延伸，对人加物体系统的启示很敏感。
In 3 experiments we investigated perception of affordances for aperture crossing for the person-plus-object system. Perceivers wielded occluded hand-held objects and determined whether they would be able to carry those objects through an aperture of a particular size. The results suggest (a) perceivers are sensitive to this affordance both when the object is wielded but not visible and when the object is visible but not wielded, (b) perception of affordances for aperture crossing while carrying an object is constrained by the same higher order inertial variable that constrains perception of extent of a hand-held wielded object (I-ij), and (c) perceivers are sensitive to this affordance both when the shoulder width of the participant contributes to the width of the person-plus-object system and when it does not. In general, perceivers treat wielded objects as an extension of their bodies and are sensitive to affordances for the person-plus-object system.
