Serial and Parallel Attentive Visual Searches: Evidence from Cumulative Distribution Functions of Response Times
Sung, Kyongje
Journal of Experimental Psychology: Human Perception and Performance, v34 n6 p1372-1388 Dec 2008
Participants searched a visual display for a target among distractors. Each of 3 experiments tested a condition proposed to require attention and for which certain models propose a serial search. Serial versus parallel processing was tested by examining effects on response time means and cumulative distribution functions. In 2 conditions, the results suggested parallel rather than serial processing, even though the tasks produced significant set-size effects. Serial processing was produced only in a condition with a difficult discrimination and a very large set-size effect. The results support C. Bundesen's (1990) claim that an extreme set-size effect leads to serial processing. Implications for parallel models of visual selection are discussed.
