Abstract
Two strategies “creeping” and “bracketing” were postulated as alternative methods of approximating a target score, and it is suggested that the use of these strategies is influenced by the conditions under which performance took place. This was tested using large and small movements of a cursor along a trackway against large and small resistances. Each S’s scores were auto-correlated, lagged once and lagged twice while learning and while continuing to respond in the absence of KR. Analysis of the variance of the transformed auto-correlations showed them to be significantly more positive for the large movement when lagged once. It was concluded that intertriai strategy was influenced by the learning conditions, and that the Ss used only the preceding trial in formulating their strategy for the next.
