The Inquisit 5 SR Research Plugin enables integration of your Inquisit tests with Eye Link eytrackers from SR Research. Using the plugin, Inquisit can programmatically access real-time data from the eye tracker such gaze point and pupil size for use in gaze-contingent task procedures. Inquisit also automatically sends task metadata to the eye tracker such as stimulus onsets, images presented, areas of interest, trial variables, and participant responses, thereby enabling rich analysis of the gazepoint stream in the SR Research Data Viewer tool.

Easily incorporate eye tracking data into Inquisit's extensive library of psychological tests

Millisecond offers an unparalleled library of tests covering almost all areas of psychology. With the Inquisit SR Reseach Plugin, these tests can be easily supplemented with gaze point analysis in order to gain additional insights into test performance. Leverage any of the paradigms in our test library, or program your own. Runs on both Windows and Mac OS X.

Rich integration with the SR Research Data Viewer tool

With the Inquisit 5 SR Research Plugin, rich meta data about visually presented stimuli are automatically sent to the eye tracking system and recoreded to the EDF file. Inquisit automatically notifies the eye tracker of stimulus onsets and areas of interest, and any presented images are sent to the eyetracker. As a result, Data Viewer can overlay fixations on any presented images, and it can replay gaze points over the stimulus presentation sequence over time.

Inquisit automatically sends trial variables and participant responses to the eye tracker, enabling the aggregation of gaze point data by condition within Data Viewer. For maxium flexiblity, custom markers can be sent to the eye tracker in order to define additional events or variables of interest for subsequent analyses.
