In two experiments, we used dual-task methodology to assess the effect of aging on executive control of working memory. We hypothesized that (1) age-related dual-task costs would be observed even when individual tasks represent different perceptual modalities; (2) age would modulate the effect of increased temporal overlap on dual-task performance; and (3) the vulnerability of specific memory mechanisms to interference would be age related. We found that aging was associated with… Expand
Adult age differences in the effects of processing on storage in working memory: A meta-analysis.
TLDR
Meta-analysis of effect sizes revealed a small but disproportionate effect of processing on older adults' memory performance and moderator analysis indicated that equating single task storage performance across age groups (titration) and the nature of the stimulus material were important determinants of memory accuracy. Expand
Predicting age-related dual-task effects with individual differences on neuropsychological tests.
TLDR
It is concluded that compromised central executive may underlie age-related decline in dual-task performance and the Memory and Motor Speed factors were the strongest predictors of single- Task performance, but the Attention/Executive factor was the most important predictor of dual- task performance.

Age effects on load-dependent brain activations in working memory for novel material
TLDR
Three competing models of cognitive aging (neural compensation, capacity limitations, neural inefficiency) were examined in relation to working memory for novel non-verbal material and it was found that cognitive aging theories can be specific to the neural networks/regions underlying the different phases of working memory.

Storage and processing in working memory: Assessing dual-task performance and task prioritization across the adult lifespan.
TLDR
The study revealed a large general cost to serial letter recall performance associated with concurrent performance of an arithmetic verification processing task, a concurrence cost that increased with age and a prioritization effect in dual-task performance for both tasks, irrespective of age, in which performance levels depended on the relative emphasis assigned to memory versus processing.

Age and Individual Differences in Working Memory: The Size Judgment Span Task
TLDR
The authors pooled data from 5 published articles where the SJS task and other measures of cognitive performance were administered to create an archival data set with 496 participants, finding strong evidence of age and individual ability differences in SJS performance. Expand

TLDR
Results from each experiment separately show age-related changes to attention and memory in temporal processing using different measures and manipulations in the same task. Expand
A common neural network for cognitive reserve in verbal and object working memory in young but not old.
TLDR
There was a latent brain pattern noted in the stimulus presentation phase that manifested similar relationships between load-related encoding activation and CR variables across the letter and shape tasks in the young but not the elder age group, which could represent a general neural instantiation of CR that is affected by the aging process.

Age Differences in the Subcomponents of Executive Functioning.
TLDR
Overall differences in EF with age are found, such that variability in age effects emerged at the task level, and updating was not as affected by age as other subdomains. Expand
Task difficulty modulates young–old differences in network expression
TLDR
A spatial pattern of fMRI activation during the probe phase whose expression increased as the response deadline shortened and the task became more difficult was identified, suggesting reduced efficiency and capacity of this network in older subjects. Expand

Age-related differences in concurrent-task performance of normal adults: evidence for a decline in processing resources.
TLDR
A concurrent-task paradigm was used to investigate age-related differences in the attentional capacity of 92 right-handed adults and suggests a reduction in a general-purpose processing resource with increasing age. Expand
Aging, executive control, and attention: a review of meta-analyses
TLDR
Age-related differences in selective attention and divided attention and dual-task and global task-switching costs were found to be additive in both young and old subjects, unmodulated by task difficulty. Expand
Task coordination and aging: explorations of executive control processes in the task switching paradigm.
TLDR
This series of three studies examined age-related differences in executive control processes and more specifically in theExecutive control processes which underlie performance in the task switching paradigm to find out whether age equivalence was observed in task switching performance. Expand
Age-related differences and similarities in dual-task interference.
TLDR
There was no evidence for a specific impairment in the ability of older adults to manage simultaneous tasks, but there was evidence for both input and output interference, which may be greater in older adults. Expand
Age differences in dual-task interference are localized to response-generation processes.
TLDR
Age differences in dual-task interference appear quite localized to response-generation processes, but it was equivalent for older and younger adults. Expand
Aging and the psychological refractory period: task-coordination strategies in young and old adults.
TLDR
The results show that participants' ability to coordinate the processing of two tasks did not decline with age, but dual-task time costs were greater in the older adults, and three sources for this increase were found: generalized slowing, process-specific slowing, and the use of more cautious task-coordination strategies by the Older adults.

Aging and dual-task performance: a meta-analysis.
TLDR
The relations between dual-task effects and aging were examined through a meta-analysis of 33 studies using latency as the dependent measure and 30 studies focusing on accuracy, and a model to explicate different types of complexity (additive and multiplicative) was developed. Expand
Divided attention abilities in young and old adults.
TLDR
No significant age difference in divided attention ability independent of single-task performance level was found in either experiment, and the existing literature must be reexamined in light of these issues. Expand
