Dalvit, Silvia; Eimer, Martin – Journal of Experimental Psychology: Human Perception and Performance, 2011
Previous research has shown that the detection of a visual target can be guided not only by the temporal integration of two percepts, but also by integrating a percept and an image held in working memory. Behavioral and event-related brain potential (ERP) measures were obtained in a target detection task that required temporal integration of 2…

Eimer, Martin; Kiss, Monika; Press, Clare; Sauter, Disa – Journal of Experimental Psychology: Human Perception and Performance, 2009
We investigated the roles of top-down task set and bottom-up stimulus salience for feature-specific attentional capture. Spatially nonpredictive cues preceded search arrays that included a color-defined target. For target-color singleton cues, behavioral spatial cueing effects were accompanied by cue-induced N2pc components, indicative of…

Tollner, Thomas; Gramann, Klaus; Muller, Hermann J.; Kiss, Monika; Eimer, Martin – Journal of Experimental Psychology: Human Perception and Performance, 2008
In cross-dimensional visual search tasks, target discrimination is faster when the previous trial contained a target defined in the same visual dimension as the current trial. The dimension-weighting account (DWA; A. Found & H. J. Muller, 1996) explains this intertrial facilitation by assuming that visual dimensions are weighted at an early…
