How to install the Psychtoolbox for Matlab on a university computer

Psychophysics Toolbox Version 3 (PTB-3) is a free set of Matlab functions for vision and neuroscience research. It makes it easy to synthesize and show accurately controlled visual and auditory stimuli and interact with the observer.

To use:

  • GStreamer and MATLAB are required to run PsychToolbox.
  • All three items (Psychtoolbox, Gstreamer, Matlab) should have a status of 'Ready' in Cloudpaging Player.
  • If MATLAB is already 'running', save any work and re-launch.
  • Success is indicated by 'PsychStartup: Adding path...' message in Command Window.
