Welcome to DPTE, an environment for tracing dynamic processes.

DPTE supports the Dynamic Process Tracing Methodology, allowing researchers to conduct experiments in the social sciences and other areas, examining human judgement and decision-making in complex processes over time.

NOTICE: Most browsers will end support for Flash on December 31, 2020, and it may not be possible to access DPTE after that date. Users should be sure to have completed all studies and downloaded their data before December 31. For more information, read this post at the DPTE blog.
