We performed three experiments to investigate the extent to which people can selectively perceive different properties of a person-probe-surface system, and the extent to which such abilities are supported by sensitivities to different (components of) invariant mechanical parameters. Participants probed a surface with a wielded object and attempted to perceive an exteroceptive property of the probe (whole length), an exproprioceptive property of the probe (partial length), and an exteroceptive property of the surface (distance). After controlling for potential confounds, we found that participants were able to selectively perceive each of these properties, and that in each case, such abilities were supported by sensitivity to distinct components of mechanical invariants. The results suggest that people can selectively attend to properties both across and within components of a person-probe-surface system and are discussed in the context of the invariant mechanical parameters that support this ability.
我们进行了三项实验，以探究人们能够在多大程度上选择性地感知人 - 探针 - 表面系统的不同属性，以及这种能力在多大程度上受到对不同（组成部分的）不变机械参数的敏感度的支持。参与者用一个挥舞的物体探测一个表面，并试图感知探针的外感受属性（全长）、探针的本体感受属性（部分长度）以及表面的外感受属性（距离）。在控制了潜在的混杂因素后，我们发现参与者能够选择性地感知这些属性中的每一个，并且在每种情况下，这种能力都受到对机械不变量不同组成部分的敏感度的支持。结果表明，人们能够在人 - 探针 - 表面系统的组成部分之间以及内部选择性地关注属性，并在支持这种能力的不变机械参数的背景下进行了讨论。
