Abstract

Abstract: It has been theorized that differential cognitive resources may be involved in the processing of information pertaining to natural and man-made categories, commonly referred to as category specificity. The present study used four experiments to assess whether a natural priming advantage exists and, if so, whether color, texture, color diagnosticity, object complexity, and familiarity could account for the categorical difference. To do so, a repetition priming paradigm was used in which masked primes were briefly presented, and targets were categorized as natural or man-made. Across four experiments, a greater degree of priming was observed for natural as opposed to man-made stimuli. Examination of stimulus characteristics that could account for the differences revealed that the natural priming advantage was in part driven by color diagnosticity and familiarity. Results of this study support the notion that different cognitive resources represent and/or are involved in the processing of natural and man-made categories.
