Working memory costs of task switching.
Although many accounts of task switching emphasize the importance of working memory as a substantial source of the switch cost, there is a lack of evidence demonstrating that task switching actually places additional demands on working memory. The present study addressed this issue by implementing task switching in continuous complex span tasks with strictly controlled time parameters. A series...
متن کاملSearching working memory for the source of dual-task costs.
Dual-task costs depend on the specific pairings of stimulus and response modalities. Such findings are analogous to domain-specific effects in the working memory (WM) literature, in which items compete for limited capacity when they involve related types of information. The present study explicitly examines the relationship between modality-pairing effects on dual-task costs and domain-specific...
متن کاملWorking memory, task switching, and executive control in the task span procedure.
Four experiments explored the task span procedure: Subjects received lists of 1-10 task names to remember and then lists of 1-10 stimuli on which to perform the tasks. Task span is the number of tasks performed in order perfectly. Experiment 1 compared the task span with the traditional memory span in 6 practiced subjects and found little difference. Experiment 2 compared the task span and the ...
متن کاملDecomposing Externally Cued Task Switching Costs
The double-cued task switching procedure has recently been introduced as a new way to measure externally cued switch costs. In the present individual differences study, two hundred fifty young adults completed measures of task switching, inhibition, and long-term memory. A latent variable approach was taken to examine the relationships among these cognitive measures. Decomposing the externally ...
متن کاملNeurophysiological measures of task-set switching: effects of working memory and aging.
We investigated age-related differences in task-switching performance by using behavioral measures and event-related brain potentials. We tested younger and older adults, and we separated older adults into groups with high and low working memory (WM); that is, we separated them into old-high-WM and old-low-WM groups. On average, all participants responded more slowly in mixed-task than in singl...
