STEP (System for Teaching Experimental Psychology) was organized by Brian MacWhinney in the Department of Psychology at Carnegie Mellon University and was funded by the National Science Foundation. The goal of STEP was to facilitate the use of E-Prime in various learning contexts. Part of this goal was achieved by creating and hosting a large set of classic experiments implemented in E-Prime.
