• Run in a floating window with real-time debugging
• Review the consultant report to identify design issues for the experiment
• Start an experience from any list for faster debugging

Timing

• Accurate stimulus presentation and response times in milliseconds
• Use event or cumulative timing mode
• Avoid input device response latencies using Chronos
• Extensive time data reports available online

Integration of External Devices

• Connect to Chronos for intuitive digital or analog communication
• Send unscripted stimuli and bookmarks using task events
• Send/receive stimuli and markers via serial or parallel port of the
• Create, drag, and drop package calls with the PackageFile Editor
• Communicate with joysticks using x/w coordinates and buttons

Data Analysis

• Data available in E-DataAid format, as well as TXT
• Save the preferred data layout for each experiment
• Merge participant data files and sessions into a file
• Be aware of the data that has been edited
• Organize descriptive analyses and automatically manage Excel charts and tables
• Export data for inferential statistics in SPSS, R, and Excel

Applications

• E-Studio: The graphical interface makes creating experiments as easy as dragging and dropping objects in procedural timelines!
• E-DataAid: This application is a data management utility specific to E-Prime. It has the ability to filter, edit, analyze and export data to external statistical packages.
• E-Run: Once your experiment is compiled, E-Run provides millisecond accuracy over stimulus presentations, synchronization, and data collection.
• E-Recovery: This application allows you to select an incomplete E-Run text file and convert it into an E-Prime data file.
• E-Merge: This application allows you to quickly and easily combine your data files on a single subject in data files from various themes.
• E-Basic: Almost identical to Visual Basic for Applications, E-Basic is the underlying scripting language of E-prime.
