Complex semantic processing old age: Does it stay or does it go?

Article Abstract:

The issue of the nature of age differences in retrieval from semantic memory was examined. Results indicate age effects in nonsemantic components although not in semantic retrieval per se.

Age differences in the selection of mental sets: the role of inhibition, stimulus ambiguity, and response-set overlap

Article Abstract:

Research describing task-switching with respect to age related changes is presented. Aging may be associated with executive control deficits and the study suggests that older adults rely on set updating processes.

Sequential and coordinative complexity in time-accuracy functions for mental arithmetic

Article Abstract:

Several theories about cognitive aging state that age-related changes in the cognitive system are brought about by a decline in some general mechanism. A research has been conducted to identify age differences in such general factors on certain aspects of cognition. Results indicate that age differences under conditions of high coordinative demands cannot be attributed solely to a decline in basic speed processing. Cognitive aging cannot be interpreted as a single construct. There are different processing modules that are relevant for cognitive aging.
