Age differences in working memory - The roles of storage and selective access


Oberauer, Klaus; Wendland, Mirko; Kliegl, Reinhold (2003). Age differences in working memory - The roles of storage and selective access. Memory & Cognition, 31(4):563-569.

Abstract

Twenty-four young (23 years) and 24 old (71 years) adults performed arithmetic tasks with working memory loads ranging from 1 to 4. Age groups were equivalent in mean accuracy and speed of arithmetic operations under minimal working memory load, but old adults were slower than young with memory demands > 1. Access to a new object in working memory as the basis of computation required additional time. This object-switching cost increased with increases in memory demand, but was unaffected by age, indicating that old adults have no deficit in selective access to working memory.
