E-Prime® 3.0 Overview
E-Prime® is the most comprehensive software available for behavioral research. Build your own experiments using E-Prime’s easy-to-use graphical interface. Design, collect, and analyze data – all within a few hours! With more than 100,000 users in research institutions and laboratories in over 60 countries, E-Prime is the world-leading behavioral experiment software. E-Prime provides a truly easy-to-use environment for computerized experiment design, data collection, and analysis. E-Prime provides millisecond precision timing to ensure the accuracy of your data. E-Prime’s flexibility to create simple to complex experiments is ideal for both novice and advanced users.
The E-Prime suite of applications includes:
- E-Studio – Drag and drop graphical interface for experiment design.
- E-Basic – Underlying scripting language of E-Prime (nearly identical to Visual Basic for Applications™).
- E-Run – Once experiment design is complete, a single mouse click generates it into an E-Basic script. E-Run then affords you the millisecond precision of stimulus presentation, synchronizations, and data collection.
- E-Merge – Quickly and easily combines your single session data files for group analysis.
- E-DataAid – Data management utility that allows you to filter, edit, analyze, and export your data.
- E-Recovery – Recovers data files in the event of early terminated experiments, or lost or corrupted files.

E-Prime® 3.0 Components
The E-Prime® suite of applications includes:
E-Studio
The graphical interface makes creating experiments as easy as dragging and dropping objects onto procedural time lines! An experiment is comprised of a series of E-Objects. Each E-Object has a set of specific properties. The properties determine the behavior of each object.
Available E-Objects include:
| Procedure | Acts as a timeline for events within the experiment. |
| TextDisplay | Allows presentation of a full screen of text. |
| ImageDisplay | Allows presentation of images in multiple formats (*.bmp, *.jpg, *.jpeg, *gif, *.png, *.tif, *.tiff, *.emf, *.wmf). |
| MovieDisplay | Allows presentation of movies in multiple formats (*.mpeg, *.avi, *.wmv). |
| Slide | Allows presentation of a combination of text, buttons, choices, sliders, images, movies and/or sound, as well as the recording of audio (SoundIn). |
| List | Contains all independent variables, attributes, and stimuli as well as controls sampling. |
| SoundOut | Allows presentation of sound files in multiple formats (including *.mp3 and *.wma). |
| SoundIn | Allows the recording of audio. |
| FeedbackDisplay | Allows automatic visual and/or audio feedback to be presented at the end of a procedure. |
| InLine | Allows advanced experiment control through inserting user-written E-Basic. |
E-Basic
Nearly identical to Visual Basic for Applications™, E-Basic is the underlying scripting language of E-Prime. The graphical representations of experiments prepared in E-Studio are automatically compiled into a complete E-Basic script with a single mouse click. Furthermore, E-Studio offers access to E-Basic. This is particularly useful if your experiment requires a non-standard operation which is not specifically addressed in the graphical interface. Just as E-Objects are graphical representations of the most common experiment operations, an InLine object allows you to insert a piece of your own custom script within the graphical representation of the experiment.
E-Run
Once your experiment is specified within E-Studio, a single mouse click compiles the experiment into an E-Basic script. This is all the code necessary to run your experiment. Once your experiment is compiled, E-Run affords you the millisecond precision of stimulus presentation, synchronizations and data collection.
E-Merge
This application allows you to quickly and easily combine your single session data files into multi-session data files. E-Merge also keeps a history on each data file. This is particularly useful in order to determine which files have been merged along with the date and location of each data file.
E-DataAid
This application is a data management utility specific to E-Prime. It features data security options as well as the ability to filter, edit, and export data to external statistical packages.
E-Recovery
This application allows you to select an incomplete E-Run text file and convert it into an E-Prime data file. This is useful in cases where the experiment is unexpectedly terminated.
Isolated Digital Interface
The Isolated Digital Interface (STP100C) safely isolates digital inputs (in the range of 0-3.3 V or 0-5.0 V) and outputs to and from an MP160, MP150 or MP100 System and includes a 3-meter DB25 M/F ribbon cable (CBL110C) to interface with E-Prime via the printer port.
