Code for eyetracking the TriCOPA videos
This experiment uses a modified version of the TriangleCOPA stimulus set, which is hosted on OSF.
We make use of PsychToolbox to handle I/O, which further requires GStreamer to support video playback. Please make sure both of those are installed and configured before running this experiment.
As of 10/25/2023, Psychtoolbox does NOT work on Apple Silicon - you will need to run this experiment on an Intel-based computer.
The experiment is intended to be run with an SR Research Eyelink II eye tracker, which outputs data in .EDF format. (Though theoretically, any SR Research eye tracker would work). We use Alexander Pastukhov's edfImport to pull this data into MATLAB for analysis. edfImport further requires you to install SR Research's EDF API.
Some analyses make use of functions from Matlab's Image Processing Toolbox
