Abstract

Although experimental psychologists measure the quality of performance in terms of either terminal accuracy or latency, no clear theoretical link has been recently made between these measurements. This paper reports two experiments which show that a fundamental limitation to performance, either in terms of speed or accuracy, is the delay since a previous movement was made. Under circumstances where eye-movements are controlled, the ensemble size appears not to affect response latency directly, but response-to-stimulus interval (RSI) has a highly significant effect. Furthermore, the accuracy of responses is independent of either ensemble size or entropy, but is again directly related to RSI. These results are discussed in terms of the instability and lability of the spatial information upon which the operator must act, and it is hypothesized that a major contributing factor to performance in serial tasks is the state of the subject's knowledge about the spaces he or she operates in.
