Spotlight descriptions claim that attention moves with a constant velocity (Tsal, 1983) and processes information in its path (Shulman, Remington, & McLean, 1979) while the zoom lens description (Eriksen & St. James, 1986) claims an inverse relation between the size of the attentional focus and processing efficiency. Two experiments utilizing target location precueing and a response competition paradigm varied the distance of attention movement, the presence of information in the path of the movement, and the distance of the information to the target. Results were consistent with the zoom lens description. Reaction time varied inversely with the distance of the information to the target and was unaffected by the distance of the attention movement and the path location of the information. Attention appears to move in a discrete manner and precueing effects reflect the time needed to locate the appropriate target.","abstract_html":"This research compares two descriptions of visual selective attention.
