Contributions of representational distinctiveness and stability to memory performance and age differences

VR Sommer, MC Sander - Aging, Neuropsychology, and Cognition, 2022 - Taylor & Francis
Long-standing theories of cognitive aging suggest that memory decline is associated with
age-related differences in the way information is neurally represented. Multivariate pattern …

Age-related differences in brain activity in the subsequent memory paradigm: a meta-analysis

D Maillet, MN Rajah - Neuroscience & Biobehavioral Reviews, 2014 - Elsevier
Healthy aging is associated with declines in episodic memory. This reduction is thought to
