title: Age-related differences in temporal and spatial dimensions of episodic memory performance before and after hundred days of practice.
abstract: Normal aging impairs the representation and integration (binding) of spatial and temporal context in episodic memory. We directly compare age differences in episodic memory in relation to processing spatial and temporal context. As part of the COGITO study, 101 younger and 103 older participants trained an object-location serial recall task for 100 sessions. Training exacerbated the recall deficit of older relative to younger adults. Younger adults improved in recall performance on both spatial and temporal dimensions. In contrast, older adults improved on the spatial dimension only. Individual differences in pretest performance and change were positively correlated across dimensions among younger adults but negatively related among older adults. We conclude that older adults are impaired at simultaneously processing spatial and temporal context and preferentially process spatial at the expense of temporal context.
