STEP E-Prime Scripts: Alphabetical List

These are sample scripts, replicating classic, unique, or interesting studies in experimental psychology. They are intended both to demonstrate the results of the studies and to show what E-Prime can do as an experiment generation framework. They are free to download, though we ask that you credit this project if you use them in a public context. Scans of articles are only to be viewed on the browser in the context of fair use and not distributed. Thanks to Yanping Dong and her students at Guangzhou Foreign Studies University for reentering and rechecking the text of 20 of the classic studies.

We also have some scripts that were submitted to us but not credited to particular authors. These are listed on two separate pages:

1. Common experimental paradigms such as n-back, Iowa Gambling, etc.

2. Student submissions, from students in Research Methods at CMU.

Click on experiment names to find out more information and to download the scripts. If you would like to see a list of scripts with no explanations or supporting materials, look at the Script List, or if you would like to download the entire experiment set without supporting materials, download the whole STEP experiment set (54 MB).
