Abstract
Thornton Horowitz (PP, in press) recently introduced a new task for exploring the temporal context of search. In this multi-item localization (MILO) task, observers search for an ordered sequence of targets, allowing us to assess both the influence of past actions and future plans on search behavior. Using static displays, we found that (1) responding to a target eliminated it from future search as effectively as removing it from the screen, demonstrating some form of memory for old targets; (2) observers consistently plan at least one target into the future. In the present work, we set the stimuli in motion. Our question was whether the memory and planning effects were location- or object-based. We found that observers can still plan ahead almost as effectively in this dynamic environment. However, memory for previous targets is essentially eliminated, suggesting that locations, not objects, were being tagged in our previous work.
