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.|
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.
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.
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.
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.
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.
