Extending effects of salience and payoffs on stimulus discrimination: an experimental simulation of prescription checking.

This study applied specific aspects of signal detection theory (target salience and decision payoffs) to examine the associations among measured attention and accuracy on a stimulus discrimination task patterned after prescription checking. 85 participants completed the d2 Test of Attention and were assigned to either a control condition with general task instructions or a payoff condition with points accumulated or lost based on ultimate performance. Participants checked simulated product order forms for clerical errors for 40 min.
