Attentional Switches and Dual-Task Interference
In four experiments, we studied the time course of interference between detection of an oddball orientation target (OT) in an 8-item circular search display, and identification of a letter target (LT) in a central stream of distractor letters. Dual-task performance for different temporal lags between targets was compared to single-task performance. When the LT preceded the OT, dual-task perform...
متن کاملWORKING MEMORY AND DUAL - TASK INTERFERENCE 1 Working Memory Capacity and Dual - Task Interference in Picture
Researchers have found no agreement on whether dual-task interference in language performance, such as dual-task interference from tone discrimination on picture naming, reflects passive queuing or active scheduling of processes for each task. According to a passive-queuing account, while a central response-selection bottleneck is occupied by the tone discrimination task, picture naming is held...
متن کاملRunning head : DUAL - TASK INTERFERENCE WITH EQUAL TASK EMPHASIS Dual
Most studies using the Psychological Refractory Period (PRP) design suggest that dual-task performance is limited by a central bottleneck. Because subjects are usually told to emphasize Task 1, however, the bottleneck might reflect a strategic choice rather than a structural limitation. To address the possibility that central operations can proceed in parallel, albeit with capacity limitations,...
متن کاملAttentional Limitations in Dual-task Performance
People's ability (or inability) to do different activities or tasks at the same time is a topic of much interest not only to psychologists, but also to the proverbial "person in the street". It is natural to wonder about what we as human beings can and cannot do. An understanding of our limitations should also have practical value, because the intelligent design of human/machine systems depends...
متن کاملDual-task interference and the cerebral hemispheres.
It has been argued that dual-task interference is reduced when the two cerebral hemispheres can carry out the two tasks independently. Evidence for this idea has arisen from studies involving manipulations such as lateralized stimulation or response, or requiring mental operations believed to depend primarily on a particular hemisphere. However, these studies have typically involved a very limi...
