Although object-based attention enhances perceptual processing of information appearing within the boundaries of a selected object, little is known about the consequences for information in the object's surround. The authors show that distance from an attended object's center of mass determines reaction time (RT) to targets in the surround. Of 2…

This paper discusses three studies which examined the interaction of dimensional dominance with the attentional components of alertness and encoding. In Study I, twenty 6- and 7-year-olds observed thirty 3-second exposures of a color, then participated in a 40-trial choice reaction time task in which the familiarized color and a novel color served…

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,…
