INHIBITION ON NONTARGETS IN TRACKING MULTIPLE OBJECTS
Tracking multiple objects is a selective attention task. Previous studies mainly concerned the facilitative processing on targets, leaving the question of processing on nontargets unsolved. The present study applied the paradigm of inattentional blindness to study the inhibitory mechanism on nontargets. A dot-probe technique was used to measure the attention on targets, nontargets, and unexpected objects. Observers needed to detect the small dot while they were tracking four targets among eight objects. Seventeen participants took part in the experiment. The performance of probe detection was better when the probe was presented on the targets than on either nontargets or unexpected objects. The detection time did not vary with the probe position. The results imply that inhibition on nontargets and unexpected objects is a mechanism in tracking objects movement, but attention shifts to the inhibited one cost little resources. The findings will be helpful for constructing visual model in designing artificial agent and aware system.
