Introducing the Task Switching Game: a paradigm for neuroimaging and online studies

Abstract

While writing this abstract I received an email, which I promptly answered. When I returned my attention to the abstract, I struggled to regain my flow of writing. In order to understand this deficit in performance associated with switching from one task to another, or "switch cost", cognitive neuroscientists use task switching paradigms to recreate similar experiences. However, many researchers may be familiar with the difficulties that accompany modifying an established paradigm to suit their experimental design, or even the challenge of creating a new, unvalidated paradigm to perturb a particular aspect of cognitive function. This software tool article introduces a novel task switching paradigm for use and adaptation in online and neuroimaging task switching studies. The paradigm was constructed with a flexible, easily-adapted framework that can accommodate a variety of designs. This paradigm utilizes three psychometrically opposed but visually similar tasks- the Digit Span, the Spatial Span, and the Spatial Rotation. In two Use Cases we demonstrate the reliable nature of overall task performance and the dependence of switch costs on certain task parameters. This task framework can be adapted for use across different experimental designs and environment, and we encourage researchers to modify the task switching game for their experiments.
