STUDIES OF COMPONENT-TOTAL TASK RELATIONS: ORDER OF COMPONENT-TOTAL TASK PRACTICE AND TOTAL TASK PREDICTABILITY.
Abstract
The purpose of this study was to examine the relationships between performance on a complex (total) task and the performance on various components of that task when the latter are practiced in different orders. The total task (The Complex Coordinator) was represented as a composite of single-level and/or double-level task components. When the order in which the various tasks was ignored, 31.6% of the total task variance could be accounted for by the component task scores, but when order of practice was taken into account total task variance accounted for varied from 32.5% up to 70.6% depending on which particular double-level and single-level tasks were combined to predict total task scores. Thus order of practice on part tasks (component tasks) with respect to the total task makes a difference in predicting total task proficiency. More specifically, observed and predicted total task scores agree better when double-level components are practiced before the total task than when they are practiced after the total task. Also, total task proficiency is significantly improved by prior practice on double-level tasks. Prior practice on single-level tasks did not lead to significant total task improvement. (Author)
