What is dual-task condition?

In this paper, dual-task conditions are described as the use of two tasks performed simultaneously, but not necessarily following all the experimental guidelines of the dual-task paradigm.

What is dual-task practice?

Background: In everyday life, people engage in situations involving the concurrent processing of motor (balance) and cognitive tasks (i.e., “dual task situations”) that result in performance declines in at least one of the given tasks.

What is dual-task balance training?

Dual-task training is defined as the ability to perform two or more cognitive and motor activities simultaneously while maintaining postural control4). compared walking speed and balance of stroke patients between performance with and without a verbal cognitive task.

Does dual-task training improve spatiotemporal gait parameters in Parkinson’s disease?

No significant changes were found for gait variability under single and dual-task conditions. Conclusion: We found both integrated and consecutive dual-task training to be safe and effective in improving several spatiotemporal gait parameters under trained and untrained dual-task conditions.

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.

How does dual task paradigm become an evidence of working memory?

Evidence from dual-task studies suggests that working memory supports the retention and implementation of verbal instructions. In three dual-task experiments, young adults’ immediate memory for sequences of spoken instructions was assessed by both action-based and spoken recall.

What is a dual task procedure motor learning?

In the dual task condition, subjects performed one of the motor tasks (or the nonmotor associative recognition task) and the auditory task concurrently. During all dual task trials, subjects were instructed to prioritize the auditory task in order to focus attention away from the motor/nonmotor task.

What is task interference?

Cognitive-motor interference refers to dual-tasking (DT) interference (DTi) occurring when the simultaneous performance of a cognitive and a motor task leads to a percentage change in one or both tasks. Several theories exist to explain DTi in humans: the capacity-sharing, the bottleneck and the cross-talk theories.

What is interference research?

Interference is a memory phenomenon in which some memories interfere with the retrieval of other memories. Essentially, interference occurs when some information makes it difficult to recall similar material. Because of this, some long-term memories cannot be retrieved into short-term memory.

How do you calculate dual cost?

Dual-task costs to each out- come were then calculated with the following formula: [(dual-task performance−single task performance) / single task performance] × 100 (Zhou et al., 2014; Manor et al., 2010; Schwenk et al., 2010).

What is dual-task interference in psychology?

The dual-task interference paradigm is one of the hallmarks of Baddeley’s approach to working memory. It assumes that if a task selectively interferes with a particular type of processing but not with another type of processing, then those two types of processing must rely on different aspects of the cognitive system.
