Tested 5 groups of 30 undergraduates each for recall of triads of spelled-out numbers (SON) or arabic numbers (AN) for 4 trials in order to examine the effects of a shift in either symbolic presentation or physical size. Recall was facilitated by size and symbolic changes, overall recall of AN was superior to that of SON, and idiosyncratic item effects were observed. The relationship between these results and isolation effects is discussed.
