Okada, Takashi; Sato, Wataru; Toichi, Motomi – Brain and Cognition, 2006
Recent findings suggest a right hemispheric dominance in gaze-triggered shifts of attention. The aim of this study was to clarify the dominant hemisphere in the gaze processing that mediates attentional shift. A target localization task, with preceding non-predicative gaze cues presented to each visual field, was undertaken by 44 healthy subjects,…

Vogel, Edward K.; Woodman, Geoffrey F.; Luck, Steven J. – Journal of Experimental Psychology: Human Perception and Performance, 2006
How long does it take to form a durable representation in visual working memory? Several theorists have proposed that this consolidation process is very slow. Here, we measured the time course of consolidation. Observers performed a change-detection task for colored squares, and shortly after the presentation of the first array, pattern masks were…

Olivers, Christian N. L.; Watson, Derrick G. – Journal of Experimental Psychology: Human Perception and Performance, 2006
The attentional blink refers to the finding that the 2nd of 2 targets embedded in a stream of rapidly presented distractors is often missed. Whereas most theories of the attentional blink focus on limited-capacity processes that occur after target selection, the present work investigates the selection process itself. Identifying a target letter…
