title: Aging and prose memory: tests of the resource-deficit hypothesis.
abstract: Two experiments tested predictions that age differences in processing resources underlie age differences in prose recall. Topic familiarity, text length, and speed of text presentation were manipulated and reduced the amount recalled in a manner consistent with the hypothesis that these variables would tax processing resources. The amount of information recalled was systematically lower in older adults, but age differences were not increased by the experimental manipulations as expected. However, measures of the putative processing resources did account for some of the age-related variance in prose recall, and relative memorability functions suggested that the experimental manipulations interfered with the quality of recall in older adults more than in younger adults. The outcome did not support the resource-deficit hypothesis as originally proposed and may best be understood in terms of factors other than age-related deficits in the measured amounts of processing resources.
