Abstract

Abstract Throwing performance, throwability perception and subjectively felt heaviness all depend on object size and weight. Here we investigate how size and weight must be detected to perceive throwability. In previous studies, the size-weight relation was detected by hefting an object in the hand and looking at it. Thus, it could be that detecting the size-weight relation and perceiving throwability entail a visual-kinesthetic multisensory process. On the other hand, it may be that a task-specific, action-relevant perceptual organization is required, meaning that we must perform a hand-arm action that is analogous to throwing to detect the perceptual information for throwability. In this case, haptic detection of size and weight via hefting would be sufficient. We tested these alternative hypotheses by manipulating the hefting method and found that when participants visually detected size and kinesthetically detected weight, they perceived throwability less accurately and less precisely than when detecting size and weight just haptically. Only in the latter case was felt heaviness consistent with perceived throwability. Hefting with eyes open or closed led to equivalent affordance perception and thus, perceiving throwability did not require multisensory processing. These results supported the task-specific device theory.

感知可扔性是否需要任务专用设备?

投掷性能、投掷感受和主观感觉的沉重程度都取决于物体的大小和重量。在这里，我们研究了如何检测尺寸和重量才能感知可丢弃性。在以前的研究中，大小-重量关系是通过举起手中的物体并看着它来检测的。因此，检测大小-重量的关系和感知可丢弃性可能需要一个视觉-动觉的多感官过程。另一方面，可能需要一个特定任务的、与动作相关的感知组织，这意味着我们必须执行类似于投掷的手臂动作，以检测可投掷性的感知信息。在这种情况下，通过称重对尺寸和重量进行触觉检测就足够了。我们通过操纵称重方法测试了这些替代假设，发现当参与者通过视觉检测到尺寸和动觉检测到重量时，他们感知到的可丢弃性不如仅通过触觉检测尺寸和重量时准确。只有在后一种情况下，才感觉到沉重与可丢弃性一致。睁开眼睛或闭上眼睛进行吸气会产生同等的可供性感知，因此，感知可丢弃性不需要多感官处理。这些结果支持了任务专用设备理论。

期刊介绍： This unique journal publishes original articles that contribute to the understanding of psychological and behavioral processes as they occur within the ecological constraints of animal-environment systems. It focuses on problems of perception, action, cognition, communication, learning, development, and evolution in all species, to the extent that those problems derive from a consideration of whole animal-environment systems, rather than animals or their environments in isolation from each other. Significant contributions may come from such diverse fields as human experimental psychology, developmental/social psychology, animal behavior, human factors, fine arts, communication, computer science, philosophy, physical education and therapy, speech and hearing, and vision research.
