Résumé
The differential effects of training and their implications. – As a general rule, repeated pratice provides an improvement in performance. However, this improvement may vary in size over subjects.
Part 1 of this review shows the pattern of individual differences exhibited at the first execution of any task progressively modify through training, at least during an initial stage. Correlations computed between successive sessions are dependent both from this sytematic "derivation" of the pattern of individual differences, and from the reliability of measures. With further practice, individual differences become stable, and then correlations between sessions only index the reliability of measures.
Part 2 is aimed at elucidating the nature of the changes elicited during the initial stage, through the study of the evolution with practice of the correlations between the training task and other tasks perform before or after training. Depending of the nature of the extraneous tasks, correlations increase or decrease according to systematic and often substantial trends. On the whole, the task specific variance does not seem to increase over successives repetitions, although problems related to variables sampling do not allow this point to be firmly established. Implications of these findings are discussed. Granted adequate postulates, the whole correlational data support a modular conception of training, which could be developed further.
