Modeling age and retest processes in longitudinal studies of cognitive abilities

Article Abstract:

Mixed effects models were used to examine the effects of age and retest on changes in various cognitive abilities and individuals (N > 800) ranging in age from 40 to 70 years were assessed for measures of memory, spatial abilities and speed on 4 occasions. In conclusion, it is suggested that both age and retest should be modeled simultaneously when analyzing longitudinal data for better research results.

Assessing the age-related effects of proactive inference on working memory tasks using the Rasch model

Article Abstract:

Inhibition-reduction theory hypothesizes that the age-related decline in working memory (WM) span is a result of a decrease in the ability to inhibit irrelevant information in WM. The results suggest that differential susceptibility to proactive interference may account for a substantial portion of the age-related decline in WM span.

What needs to be explained to account for age-related effects on multiple congnitive variables?

Article Abstract:

The age-related influences across a number of cognitive variables in 204 adults ranging from 18 to 91 years of age was investigated using structural equation methodology. It is found that at least 3 statistically distinct types of age-related problems are operating on a wide variety of cognitive variable.
