Abstract

The goal of this research was to examine a method for predicting retention and retraining performance of a manual skill after controlled training. In an experiment, 40 men were trained to criterion performance on low- or high-workload tracking tasks, then retested and retrained after no-practice intervals of 1 to 6 wk. Retention and retraining performance times were modeled as a function (1) average tracking completion time during initial training and (2) a power-model point-estimate of training completion times. The power model predicted retention and retraining times lightly better than the average times, but both models were significant (.64 > square-R < .78). Performance times were not related to duration of retention and were marginally related to training workload. Over-all, later performance was well predicted by earlier task performance, but retention was independent of the elapsed no-practice time period. Verf.-Referat
