Conceptual grouping effects in visual search: categories matter (and named categories matter more)

Find... Typical search slopes are about twice as steep for the unfamiliar symbols compared to familiar numbers (e.g., Wang, Cavanagh, Green, 1994)-an effect that has been attributed to differences in perceptual familiarity. BUT confounded with perceptual familiarity is meaningfulness. If perceptual processing depends on meaningfulness, then placing an otherwise unfamiliar item into a meaningful category, should lead to more efficient visual processing.
