Numerous studies showed decreased performance in situations that require multiple tasks
or actions relative to appropriate control conditions. Because humans often engage in such …

In the context of performance optimizations in multitasking, a central debate has unfolded in
multitasking research around whether cognitive processes related to different tasks proceed …

Although there are well-known limitations of the human cognitive system in performing two
tasks simultaneously (dual-tasking) or alternatingly (task-switching), the question for a …

As humans acquire skills there are dramatic changes in brain activity that complement the
profound changes in processing speed and effort seen in behavioral data. These changes …

Human behavior is remarkably complex—even during the performance of relatively simple
tasks—yet it is often assumed that learned associations between stimuli and responses …

Background Driver distraction is a significant cause of traffic accidents. The aim of this study
is to investigate Electroencephalography (EEG) dynamics in relation to distraction during …

Top-down controlled selective or divided attention to sounds and visual objects, as well as
bottom-up triggered attention to auditory and visual distractors, has been widely …

Background A major question in understanding the functional organization of the brain is to
delineate the functional divisions of the prefrontal cortex. Of particular importance to the …

The neural processes underlying the ability to divide attention between multiple sensory
modalities remain poorly understood. To investigate the role of the dorsolateral prefrontal …

Using functional magnetic resonance imaging (fMRI), we measured brain activity of human
participants while they performed a sentence congruence judgment task in either the visual …
