What does a dual-task paradigm measure?
The dual-task paradigm is an established methodology to measure performance capability under these conditions where attention must be divided between two concurrently performed tasks.
What are dual-task studies?
Dual task paradigms are widely used in experimental psychology to study the degree to which different mental faculties are independent of one another (if the two tasks do not interfere), or load upon shared resources (if they do interfere).
What is the dual-task procedure and what is its purpose?
Background: The dual-task paradigm is a procedure in which subjects are asked to perform two behavioral tasks concurrently, each of which involves a distinct goal with a unique stimulus-response association.
What is a dual-task test?
Dual-task tests that include both gait and verbal tasks may entail outcomes that vary depending on cognitive capacity [20, 21]. Such tests commonly involve straight-line walking [18, 22] or the mobility test Timed Up-and-Go (TUG) [19, 23], combined with an attention-demanding verbal task [24].
What is dual-task processing?
Definition. Dual-task performance requires an individual to perform two tasks (i.e., Task A and Task B) simultaneously. Typically this type of performance is contrasted with single-task performance in which the individual only has to perform one task at a time (Task A or B).
Why is dual-task important?
Physiologically, dual tasking encourages, compels, and at times all out forces the brain to process motor tasks in one of four procedural memory centers: basal ganglia, cerebellum, supplementary motor area, and the premotor cortex.
What is dual-task interference?
Simultaneous performance of two tasks often leads to performance deficits in the component tasks. This effect, known as dual-task interference, is thought to be a proof of capacity limitation in cognition, and the lateral prefrontal cortex (LPFC) has been highlighted as its putative neural substrate.
What is the dual-task technique?
Method: Conducted an experiment in which participants were asked to perform two tasks at the same time (dual task technique) – a digit span task which required them to repeat a list of numbers, and a verbal reasoning task which required them to answer true or false to various questions (e.g., B is followed by A?).
Why do we see a dual-task cost?
Consequently, due to a competition of the same pool of cognitive resources (Navon and Gopher, 1979), a worsening of the performance occurs, known as dual-task cost (e.g., there is a reduction of performance in dual-task performance, compared to single-task performance).
