Updating a Classic: A New Generation of Vignette Experiments Involving Iterative Decision Making

Although the vignette method is widely used in psychology, it is often implemented without the key feature of iterative decision making that can affect the eventual outcome of the vignettes. This Tutorial provides an explanation of how to use Twine, an interactive narrative platform, to create vignettes with iterative decision making. Twine is an especially useful tool for experiments involving branching narratives, spatial navigation, and resource allocation. We provide code for creating exemplar experiments in social and cognitive psychology, as well as behavioral economics, and explain how to integrate Twine projects with survey-management platforms, such as Qualtrics. After following this Tutorial, researchers will be able to use Twine in their experiments to update the classic vignette method by incorporating iterative decision-making tasks
