Abstract
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.
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.
