Dual task research

Basic data for this project

Description

A different research focus is the investigation of executive processes that are required to coordinate the processing stages in dual tasks. It has often been assumed that executive processes control the temporal scheduling of potentially interfering processing stages. As a result of this scheduling, dual-task costs, e.g., an increase in processing time or errors during the simultaneous processing of two tasks compared to the processing of single tasks, can be observed. However, some recent results indicate that dual-task costs may disappear after prolonged dual-task practice. One main goal of this project is to specify the nature of the learning processes leading to the disappearance of dual-task costs in the PRP paradigm. What exactly is learned during repeated dual-task performance? That is, which kind of executive knowledge enables participants to perform the tasks without any dual-task costs?
