A dual-task paradigm is a procedure in experimental neuropsychology that requires an individual to perform two tasks simultaneously, ...
The dual-task n-back task is a variation that was proposed by Susanne Jaeggi et al. in 2003. [5] In the dual-task paradigm, two independent sequences are presented simultaneously, typically using different modalities of stimuli, such as one auditory and one visual. Several smart phone apps and online implementations of the dual n-back task ...
When studying the costs of multitasking there are typically two designs for or types of multitasking that are examined, task switching and dual tasking. Task switching involves shifting one’s attention from one thing to another. Dual tasking, on the other hand, is when attention is divided among multiple things at once.
Performance on these tasks is disrupted when a switch from one task to another is required. This disruption is characterized by a slower performance and decrease in accuracy on a given task A on a trial that follows the performance of a different task B ("alternating" or "switch" trial) as opposed to performance on task A when it follows another trial of task A ("repetition" trial).
Using the dual-task paradigm, Baddeley and Erses have found, for instance, that patients with Alzheimer's dementia are impaired when performing multiple tasks simultaneously, even when the difficulty of the individual tasks is adapted to their abilities. [6] Two tasks include a memory tasks and a tracking task.
Get a task card: The programmer gets the task card for one of the tasks to which he or she has committed. Find a Partner: The programmer will implement this task along with another programmer. This is further discussed in the practice Pair Programming. Design the task: If needed, the programmers will design the functionality of the task.
Interference theory says that the learning of new information decreases the retrieval of older information, and this is true for dual-task interference. The dominant task of the two inhibits the other task from completion. It is presumed that the dominant task would be a new task as a previously accomplished task would already be stored in memory.
Some types of exercise (gait, balance, co-ordination and functional tasks; strengthening exercise; 3D exercise and multiple exercise types) improve clinical balance outcomes in older people, and are seemingly safe. [15]
