Converging evidence that visuospatial cognition is more age-sensitive than verbal cognition

Article Abstract:

Age-related differential deficits in verbal and visuospatial performance were examined. Differential deficits observed strongly indicate that visuospatial cognition is more affected by aging than verbal cognition.

Age differences in item manipulation span: The case of letter-number sequencing

Article Abstract:

The effect of age differences in performance of memory tasks requiring complex item manipulation, like letter-number sequencing, is examined. It is found that age differences are largest when participants are remembering familiar sequences, suggesting that older adults are unlikely to forget familiar sequences soon and remember new sequences instead.

Cross-sectional and longitudinal relationships among age, cognition, and processing speed

Article Abstract:

Change in intellectual function is significant in cognitive aging research, although most studies do not concentrate on age-associated change over time. The processing speed hypothesis is one theory of cognitive aging, and this has been tested by comparing how well speed may account for age differences in cognitive function, versus within-person change over time. Statistical control of processing speed reduced cross-sectional age affects, although did not attenuate longitudinal age effects.
