Dual task protocols are often used to assess the simultaneous performance of two tasks. However, the cognitive and perceptual load factors of empirically studied dual tasks often vary considerably. Thus, the current pilot study systematically investigated the effects of dual task constraints across varying levels of complexity, for three groups of neurologically healthy adults, by closely manipulating cognitive and perceptual load factors. Using a novel methodology, performance was measured… Expand

Aging and input processing in dual-task situations.
TLDR
These findings indicate that parallel processing at the input stages of dual-task performance requires cognitive control and an age-related decline in the control of input processes should be considered as one source of age effects in dual- task performance. Expand

TLDR
These conclusions challenge widely accepted ideas about attentional resources and probe reaction time methodologies and suggest new ways of thinking about continuous dual-task performance, effects of extraneous stimulation, and automaticity. Expand
The Effects of Aging and Dual Task Demands on Language Production
TLDR
The utility of using a digital pursuit rotor to study the effects of aging and dual task demands on language production is demonstrated and prior findings that young and older adults use different strategies to accommodate toDual task demands are confirmed. Expand
Training effects on dual-task performance: are there age-related differences in plasticity of attentional control?
TLDR
The results indicate that, even when the 2 tasks required similar motor responses, both older and younger adults could learn to perform the tasks faster and more accurately, and the improvement in performance generalized to new task combinations involving new stimuli. Expand
Transfer Effects in Task-Set Cost and Dual-Task Cost After Dual-Task Training in Older and Younger Adults: Further Evidence for Cognitive Plasticity in Attentional Control in Late Adulthood
TLDR
The results suggest that dual-task skills can be substantially improved in older adults and that cognitive plasticity in attentional control is still possible in old age. 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
The effects of age and task domain on dual task performance: A meta-analysis
Recent research has provided mixed findings as to whether older adults find dual tasking problematic. Here, we examined whether methodological variations across studies can account for theExpand
Virtually Perfect Time Sharing in Dual-Task Performance: Uncorking the Central Cognitive Bottleneck
TLDR
The three experiments reported here support the hypothesis that after relatively modest amounts of practice, at least some participants achieve virtually perfect time sharing in the dual-task performance of basic choice reaction tasks. Expand
Dual-task interference with equal task emphasis: Graded capacity sharing or central postponement?
TLDR
This work conducted two dual-task experiments with equal task emphasis to evaluate the possibility that central operations can proceed in parallel, albeit with capacity limitations, and found a pattern of results consistent with the existence of a structural central bottleneck. Expand

TLDR
The results indicate that independent measures of the LRP can be obtained for each of 2 concurrent tasks, and the 1st task may cease to interfere with the 2nd considerably before producing an overt response. Expand
