Reproducible science

Experiment Factory is an “an open source framework for the development and deployment of web-based experiments.” We developed this platform to run our large scale multiwave online experiments. It consists of a Python application and a repository of behavioral experiments and surveys coded in javascript using jsPsych (de Leeuw, 2015). As we hoped for it has been used by other researchers for their experiments as well.


Psychology is rich with related constructs on self-regulation (e.g. impulsivity, self-control, inhibition etc.) and even richer in behavioral tasks and surveys to measure these putative constructs. It does lack, however, a clear understanding of how these constructs and the measures relate to each other. As part of the Science of Behavior Change initiative we addressed this question by running a large battery (35 tasks, 23 surveys) on a large sample (n=552).
