The reliability and consistency of individual differences in motor control. II

Abstract

An analysis of data based on 80 subjects suggests that steadiness is a dynamic function. Practice effects appear with repeated sittings. Measures of steadiness occupying a short time in few sittings give only a fair index of individual ability. "The most important implication of this thesis is the increased emphasis which should be placed upon repeated examinations of individuals at different times rather than the completion of testing procedures within a given examination period." A coefficient of trait variability is proposed based on the test-retest r and odd-even r . (PsycInfo Database Record (c) 2025 APA, all rights reserved)
