Use of factor analysis in the study of alcohol-induced strategy changes in skilled performance on a soccer test

The present study was designed to examine how skilled behaviour changes under the effects of two doses of alcohol (0.5 gm/kg and 1 gm/kg). A battery of perceptual-motor reference tests, together with the criterion test of a soccer slalom were given a sample of 48 male volunteers to show how performance strategies changed across the different experimental conditions. Analysis indicated little change between effects of placebo and the lower dose but some change in the composition of performance between placebo and the 1 gm/kg dose. This finding supports further use of factor analysis in the study of skilled behaviour.
