Dual task paradigm

The dual-task paradigm describes a type of experiment in neuropsychology in which a test person is supposed to do two tasks at the same time. The performance of the simultaneous processing of the tasks is then compared with the performance of each individual processing. If the performance is lower in the former form than if the tasks are done individually, then it is assumed that both tasks compete for memory space for information processing in the brain.

For example, you can easily quote a poem while riding a bicycle. Both tasks are solved equally well together or individually. On the other hand, it is difficult to quote a poem while writing an essay because both activities are controlled by the same centers in the brain.

In connection with the dual-task paradigm, it is assumed that the capacities for information processing processes in humans are limited and can be divided into different classes.
