Memory changes with normal aging: Behavioral and electrophysiological measures

Memory changes with normal aging: behavioral and electrophysiological measures.

We examined performance in young and elderly on an implicit (lexical decision) and an explicit (recognition) memory test. The difference in lexical decision times between old and new words was equivalent in the two groups, although the elderly were slower. In both groups, recognition accuracy (lower in the elderly) was higher following semantic than nonsemantic encoding, whereas lexical decisio...

Implicit and explicit memory processes in panic patients as reflected in behavioral and electrophysiological measures.

Implicit and explicit memory processes for panic-relevant and neutral word stimuli were examined in 16 panic patients and 16 healthy participants matched for sex, age, and education, using behavioral and electrophysiological measures. In the study phase, panic-relevant and neutral words were presented and the level of processing was varied by requiring either shallow (orthographic) or deeper (s...

The neurobiology of memory changes in normal aging.

Cognitive alterations occur over the lifespan of every species studied and have been quantified carefully in humans, other primates and rodents. Correspondingly, changes in hippocampal function have been associated with a number of observed memory impairments across species. It appears that humans, alone, show Alzheimer's disease-like cognitive and neural pathology spontaneously. Thus, a compar...

Autobiographical memory and aging

Autobiographical memory, or memory for personal experiences, allows individuals to define themselves and construct a meaningful life story. Current research aims to review the definition and theories of autobiographies memory and how it usually changes or abnormally in older adults. Base on studies, as we grow older autobiographical memory drops off, also semantic memory changes a little or som...
