INVESTIGATING AGE-RELATED INHIBITORY DEFICITS IN SPATIAL WORKING MEMORY

Age-related inhibitory effects were investigated during spatial memory performance. In Experiment 1, 15 young (M = 20 years) and 16 old adults (M = 70 years) completed two spatial tasks (i.e., Block Suppression Test, Corsi Block Tapping Test) that differed in need for inhibitory processing. Accuracy differences within each task revealed age-related differences in spatial working memory and between task differences revealed that older adults had difficulty ignoring irrelevant items. Experiment 2 (10 young, 10 old adults) examined whether the distractibility of irrelevant items in the inhibition task (i.e. BST) accounted for the age-related inhibitory effects. Findings were largely consistent with the initial experiment indicating that inhibitory function was affected by adult aging.
