There is no consensus regarding the origin of behavioral interference that occurs during concurrent multitasking. Some evidence points toward a multitasking locus in the brain, while other results imply that interference is the consequence of task interactions in several brain regions. To investigate this issue, we conducted a functional MRI (fMRI) study(More)
In this paper we propose a method to create data-driven mappings from components of cognitive models to brain regions. Cognitive models are notoriously hard to evaluate, especially based on behavioral measures alone. Neuroimaging data can provide additional constraints, but this requires a mapping from model components to brain regions. Although such(More)
While multitasking has received a great deal of attention from researchers, we still know little about how well people adapt their behavior to multitasking demands. In three experiments, participants were presented with a multicolumn subtraction task, which required working memory in half of the trials. This primary task had to be combined with a secondary(More)
Working memory can be a major source of interference in dual tasking. However, there is no consensus on whether this interference is the result of a single working memory bottleneck, or of interactions between different working memory components that together form a complete working-memory system. We report a behavioral and an fMRI dataset in which working(More)
Investigations into multitasking have shown that overlap in cognitive resource use between tasks leads to lower performance. Various computational models have been developed to explain this phenomenon. However, most concurrent multitasking models have been tested in dual-task situations only. In order to see if single-task models could explain dual-task(More)
With the ever-increasing stream of information we are expected to deal with on a moment-to-moment basis, human multitasking behavior has become an important part of modern society. Multitasking can occur on many different timescales. Our interest is in concurrent multitasking: attempting to fulfill multiple goals in parallel. There have been many(More)
