Stimulus Response System


SKU: SRS-100 Category:



  • Record biopotentials such as ECG, EMG, EEG, EOG, etc..
  • Record EDA ( GSR, SCL, SCR) activity
  • Record Temperature, Pressure, etc.
  • Mark onset of Visual Stimuli
  • Record responses with the RPD-400 and EM-220
  • Present Audio-Visual stimuli with Experiment Builder
  • Use Digital outputs to send events to external devices.
  • Accept exetrnal TTL Digital Inputs from other devices.
  • Prebuilt experiments for common psychological tests, such as Stroop effect, Gaze-CueParadigm, Eriksen Flanker Test,…
  • Use multiple monitors
  • Does not need multiple computers
  • Use the Stimulus Response Module to automate data analysis
  • Site License included

Experiment Builder:

  • Present Media, such as images, movies, sounds.
  • Use spreadsheets to automate tasks.
  • Graphical User Interface.
  • Cross-platform application, running on Windows or Mac OS X


  • Use iWire-AM to monitor the onset and the peak amplitude of the audio, including participant vocal response via microphone.
  • Sync with Gazepoint Eyetrackers.
  • Use iWorx-Serial-Interface to sync with serial output devices
