چکیده

Can visual search tasks be combined without cost? To answer this question we had subjects search for one target character in a series of 12 rapidly presented frames. The type of processing, controlled or automatic, was manipulated by requiring search for variably mapped (VM) or consistently mapped (CM) target and distractor sets. Conditions included VM-only search (controlled processing), CM-only search (automatic processing), and simultaneous CM/VM search. Joint automatic and controlled search with emphasis on the controlled search task produced no loss of detection sensitivity in either task but did produce a large criterion shift in the automatic search task. Without instructional emphasis on the controlled search task, controlled search deteriorated. Subjects also showed a tendency to waste controlled processing resources when performing an automatic process. Automatic processing became less resource demanding with practice. However, controlled processing was always sensitive to resource reductions. The results show that subjects can sometimes perform dual search tasks without noticeable deficit when one of the tasks is automatic. The implications of these results are discussed.
