Al-Aidroos, Naseem; Emrich, Stephen M.; Ferber, Susanne; Pratt, Jay – Journal of Experimental Psychology: Human Perception and Performance, 2012
In four experiments we assessed whether visual working memory (VWM) maintains a record of previously processed visual information, allowing old information to be inhibited, and new information to be prioritized. Specifically, we evaluated whether VWM contributes to the inhibition (i.e., visual marking) of previewed distractors in a preview search.…

Watson, Derrick G.; Kunar, Melina A. – Journal of Experimental Psychology: Human Perception and Performance, 2012
In visual search, a set of distractor items can be suppressed from future selection if they are presented (previewed) before a second set of search items arrive. This "visual marking" mechanism provides a top-down way of prioritizing the selection of new stimuli, at the expense of old stimuli already in the field (Watson & Humphreys,…

Eimer, Martin; Kiss, Monika; Nicholas, Susan – Journal of Experimental Psychology: Human Perception and Performance, 2011
When target-defining features are specified in advance, attentional target selection in visual search is controlled by preparatory top-down task sets. We used ERP measures to study voluntary target selection in the absence of such feature-specific task sets, and to compare it to selection that is guided by advance knowledge about target features.…

Hollingworth, Andrew; Rasmussen, Ian P. – Journal of Experimental Psychology: Human Perception and Performance, 2010
The relationship between object files and visual working memory (VWM) was investigated in a new paradigm combining features of traditional VWM experiments (color change detection) and object-file experiments (memory for the properties of moving objects). Object-file theory was found to account for a key component of object-position binding in VWM:…

Makovski, Tal; Jiang, Yuhong V. – Journal of Experimental Psychology: Human Perception and Performance, 2009
When tracking moving objects in space humans usually attend to the objects' spatial locations and update this information over time. To what extent do surface features assist attentive tracking? In this study we asked participants to track identical or uniquely colored objects. Tracking was enhanced when objects were unique in color. The benefit…

Kerzel, Dirk; Ziegler, Nathalie E. – Journal of Experimental Psychology: Human Perception and Performance, 2005
Visual short-term memory (VSTM) was probed while observers performed smooth pursuit eye movements. Smooth pursuit keeps a moving object stabilized in the fovea. VSTM capacity for position was reduced during smooth pursuit compared with a condition with eye fixation. There was no difference between a condition in which the items were approximately…
