E-Prime Key Features

  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. Click here to view interface.

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 BMP format.
Slide	allows presentation of  a combination of text, images and/or sound.
List	contains all independent variables, attributes, and stimuli as well as controls sampling.
SoundOut	allows presentation of sound files in WAV format.
FeedbackDisplay	allows automatic visual and/or audio feedback to be presented at the end of a procedure.
InLine	allows the flexibility to extend the E-Studio application by inserting user-written E-Basic script into the experiment.

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
E-DataAid  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. Click here to view interface.

 

  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 unexpectedly terminated and the data file is lost or becomes corrupted.
