Experiment Control 

EGI-ERP

EGI currently supports a two-machine solution for experiment control.

Net Station records multiple tracks of stimulus or other external events along with the high-density EEG data.

A second computer generates and presents the stimuli and sends simple triggering or complex stimulus identification information to Net Station.

This information can then be used for off-line segmentation and averaging.

EGI also makes its experiment control interface (ECI) available to users who wish to integrate with other experiment control systems.

New this Fall

EGI is pleased to announce the arrival of the Network Timing Protocol (NTP) solution.

Working with E-Prime's developer, Psychology Software Tools, EGI has developed a workstation that allows the researcher to take advantage of the flexibility and ease of use of E-Prime in the demanding environment of ERP experiments.

The workstation includes the E-Prime for Net Station software, PC, and dual monitor hardware configuration that has been tested for reliability and accuracy with the Net Station data acquisition software. EGI also offers a Portable solution for experimental control for use in conjunction with our portable GES 300. This lightweight dual laptop configuration allows researchers to take their recordings into a variety of settings including schools, day care centers, and participants' homes.

E-Prime for Net Station, like its cousin E-Prime, is a revolutionary software suite designed for creating and running psychological experiments.

E-Prime for Net Station allows the user to develop experiments using either its intuitive graphical user's environment or its scripting language and then to run those experiments in conjunction with Net Station to create millisecond-precision ERP experiments using visual or auditory stimuli.  

E-Prime® is a suite of applications to fulfill all of your computerized experiment needs. Used by more than 15,000 professionals in the research community, 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.
