What is divided attention?
Divided attention is the ability to allocate attention across two or more tasks or sources of information.
What does dual-task performance describe?
Dual-task performance refers to tasks that overlap in time and are performed together.
How can multitasking differ from simultaneous task performance?
Multitasking can involve overlapping tasks or rapidly switching between them; switching is not the same as doing tasks simultaneously.
What is a dual-task cost?
A dual-task cost is the change in speed, accuracy, or another performance measure between single-task and dual-task conditions.
Why measure both tasks in a dual-task study?
Measure both tasks alone and during dual-task performance; one task may worsen while the other is protected.
How can prioritizing one task affect the other?
People may preserve a high-priority task by allowing performance on the other task to suffer.
What happens in the psychological refractory period paradigm?
Two signals arrive close together and each requires a speeded response; the second response is usually more delayed when the signals are closer in time.
How does timing affect dual-task interference?
When tasks demand the same processing operation at nearly the same time, they tend to interfere more.
At what processing stages can dual-task interference arise?
Interference can arise during perceptual processing, central decisions, or response execution.
How can task difficulty affect interference?
A demanding task leaves less capacity available for another task, so interference may increase as either task becomes harder.
Do different sensory modalities eliminate dual-task interference?
Different sensory modalities do not guarantee freedom from interference; tasks may still compete for central processing.
How can people coordinate competing tasks?
People can manage competing tasks by prioritizing one, scheduling parts in sequence, or adjusting how attention is shared.
