Abstract

ABSTRACT Perceived heaviness is a function of both the muscle activity used to wield an object and the resulting movement. Wielding reveals invariant properties of the effector-object system, such as rotational inertia. Recent research has proposed a psychophysiological mechanism for perceiving the heaviness of a handheld object through dynamic touch that captures how arm muscle activity and angular movement combined reveal this invariance (Waddell, Fine, Likens, Amazeen & Amazeen, 2016). The current study extends this hypothesis by investigating the dynamics of heaviness perception with the leg. Participants lifted objects of varying mass with knee extension lifts while reporting perceived heaviness. During each lift, the electromyogram (EMG) was recorded from the quadriceps, and peak angular acceleration was recorded about the knee. The resulting psychophysiological function revealed the hypothesized ratio of muscle activity to movement, similar to that found in Waddell et al. (2016). This suggests that the dynamics for heaviness perception in the leg is similar to that shown in the arm in previous work.

物体重量的腿部感知

感知到的重量是用来挥舞物体的肌肉活动和由此产生的运动的功能。挥舞揭示了效应器-物体系统的不变特性，例如转动惯量。最近的研究提出了一种通过动态触摸感知手持物体重量的心理生理机制，该机制捕捉了手臂肌肉活动和角度运动是如何结合起来揭示这种不变性的(Waddell, Fine, Likens, Amazeen & Amazeen, 2016)。目前的研究扩展了这一假设，通过调查与腿的重量感知的动态。参与者用伸展膝盖的方法举起不同质量的物体，同时报告他们感觉到的重量。在每次举重过程中，记录股四头肌肌电图(EMG)，并记录膝盖周围的峰值角加速度。由此产生的心理生理功能揭示了假设的肌肉活动与运动的比例，类似于Waddell等人(2016)的发现。这表明，在腿的重量感知动力学类似于在先前的工作中显示在手臂。

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.
