AB - Examines 10 possible sources of individual and developmental differences in memory span (rehearsal, grouping, chunking, retrieval strategies, item identification, item ordering, capacity, susceptibility to interference, search rate, and the output buffer) by drawing on existing research. Considerable evidence suggests that the speed with which presented items can be identified is a major source of both individual and developmental differences in span. By contrast, there is no conclusive evidence that the other possibilities examined, including those traditionally associated with span differences (rehearsal, grouping, chunking, and overall information-processing capacity), contribute to variations in span. Speed of item identification differences is discussed in terms of processing efficiency or the capacity needed to activate appropriate perceptual/cognitive units and linguistic programs. (4 p ref)
