Effects Of Density On Identification And Discrimination In Visual Symbol Perception

24 Ss viewed 200 slides at a 1-sec. exposure. "The slides varied in number of different letters (categories) contained and density of categories. Half of the Ss identified the categories; half reported the number of categories displayed." It was concluded that a "distinction must be made between information processed as identified categories and as discriminated categories or between perceptual capacity and short term memory capacity. The results indicate that perceptual capacity is the greater of the two." From Psyc Abstracts 36:02:2CP94T. (PsycINFO Database Record (c) 2006 APA, all rights reserved)
