Dual-task paradigm
Encyclopedia
A dual-task paradigm is a procedure in experimental (neuro)
psychology
that requires an individual to perform two tasks simultaneously, in order to compare performance with single-task conditions.
When performance scores on one and/or both tasks are lower when they are done simultaneously compared to separately, these two tasks interfere with each other, and it is assumed that both tasks compete for the same class of information processing resources in the brain.
For instance, reciting poetry while riding a bike are two tasks that can be performed just as well separately as simultaneously. However, reciting poetry while writing an essay should deteriorate performance on at least one of these two tasks, because they interfere with each other.
The interpretation of dual-task paradigms follows the view that human processing resources are limited and shareable and that they can be subdivided into several classes.
Recent research shows that practicing the dual n-back task may improve working memory
and fluid intelligence.

Working memory
Working memory has been defined as the system which actively holds information in the mind to do verbal and nonverbal tasks such as reasoning and comprehension, and to make it available for further information processing...
