Abstract

This study investigates the effects of active attention on the detection of a change between two visual scenes. In the integration of information across scene over time, failure of the integration means that the item changed whereas success of the integration results that the item is the same as before. In the change detection task using the one-shot method, there are the target present trials that require the detection of one item changes and other items are the same as before, and the target absent trials that require the detection of all items are the same as before. In the target present trials subject's performances in the detection of the change target dropped as set-size increased when they attended to change item. Otherwise, in the target absent trials subject's performances in the detection of the all items are the same as before (there is no change target) was not affected by set size when they attended to change item. These suggest that serial search property is shown only in the detection of the change item. However when subjects attend the no-change item voluntary, subject's performances in the detection of the no-change target was dropped as set-size increased in the target present trials. Otherwise, in the target absent trials subject's performances in the detection of the all items changed was not affected by set size. These results show that serial search property of the change detection depends on subject's active attention state. This work was supported by MEXT. Japan ORC (2005–2009).
