Abstract

Over a large body of literature focused on perceptual-motor coordination for action-based affordance tasks, little regard has been given for measurement reliability. The purpose of this paper was to outline this issue and provide an example reliability study for a measure of an individual’s ability to perceive action opportunities for leaping. Ten participants completed three testing sessions, each consisting of 24 trials of the task. Reaction times and accuracy of perceptual responses were calculated. Analysis of variance was used to test for systematic mean changes. Intraclass correlation coefficients (ICCs) and coefficients of variation (CV) were used to quantify intersession agreement and within-subject variability. With the removal of six trials for familiarization, acceptable agreement (ICC= 0.930) and within-subject variability (CV= 9.5%) were established, using six further testing trials. Overall, this paper provides the rationale and simple methods for addressing measurement reliability in perceptual-motor coordination research.

摘要

在大量关注基于动作的可供性任务的感知运动协调的文献中，很少考虑测量可靠性。本文的目的是概述这个问题，并提供一个示例可靠性研究，用于衡量个人感知跳跃动作机会的能力。10 名参与者完成了三个测试阶段，每个阶段包含 24 次任务试验。计算反应时间和知觉反应的准确性。方差分析用于检验系统平均变化。组内相关系数 (ICC) 和变异系数 (CV) 用于量化会话间协议和受试者内变异性。去除六项熟悉试验后，可接受的一致性（ICC = 0.930）和受试者内变异性（CV = 9. 5%) 建立，使用六次进一步的测试试验。总体而言，本文提供了解决感知运动协调研究中测量可靠性的基本原理和简单方法。
