A comparative study of aptitude patterns in unskilled and skilled psychomotor performances

Abstract

"A cross-sectional and longitudinal comparison was made of abilities involved at early and late stages of proficiency on a variety of complex psychomotor tasks… [by]… giving extended practice on seven different tasks to the same Ss who also received a battery of reference tests [from factor analyses]… . Factors were defined by the reference tests, and the resulting loadings of these in different stages of practice in the psychomotor tasks were examined. The results confirm and extend previous findings… which indicate considerable, but systematic, changes in the patterns of abilities contributing to proficiency on complex tasks as training continues and proficiency increases." 18 references.
