Abstract/Description
-
A category effect of alphanumeric characters in a visual search paradigm was examined to see whether the effect could be accounted for by the number of memory comparisons or by an early stage of perceptual processing. In Experiments 1 and 2, subjects searched for targets in either a within-category or between-category condition. The two experiments differed by the point in the trials where "catch trials" were presented. Experiment 3 used new configurations based on Gestalt principles which...
Show moreA category effect of alphanumeric characters in a visual search paradigm was examined to see whether the effect could be accounted for by the number of memory comparisons or by an early stage of perceptual processing. In Experiments 1 and 2, subjects searched for targets in either a within-category or between-category condition. The two experiments differed by the point in the trials where "catch trials" were presented. Experiment 3 used new configurations based on Gestalt principles which had been shown to influence target detection times at an early level of perceptual processing. The results of Experiments 1 and 2 favored a perceptual explanation mediating the effect. In Experiment 3, the critical interaction of category and Gestalt factors which would have demonstrated a competition in perceptually parsing the display fell short of significance.
