Abstract: | Reviews previous studies of immediate memory for digits in which exposure time per digit was 1 sec. .3 sec., and results could be derived as percentages correct at each numerosity level. The survey indicates that the channel capacity (>90% correct) of unpracticed adolescents and adults of average and above average intelligence is 6, 1. There is some evidence that, at exposure times of 1 sec/stimulus array, the span of apprehension falls within this same range. (PsycINFO Database Record (c) 2010 APA, all rights reserved) |
