Expanding dual-task research by a triple-task

Abstract Multitasking research in the laboratory is dominated by extremely simplistic dual-task paradigms. Although dual-tasks allow for some variations, they do not compare well to more complex everyday task settings. This study expands a classical paradigm adding third task. The and triple-task always consisted of same three single tasks. aim was investigate effects combinations single-tasks which manner response times costs increased. Stimulus-response pairings were varied either once within participants (E1) or between (E2). Our results showed that increase time from triple-tasks only 43% suggesting non-linear cost Moreover, each subtask higher situations compared single-task situations. contrast dual-tasks, typically one two responses delayed. Cognitively, triple-tasks, unlike coordination seems play larger role classically suggested relationships stimulus terms their modality- ideomotor-compatibility we will discuss. Overall, demonstrates current multitasking limited its generalizability focusing on would benefit with
