The Psychophysics Toolbox interfaces between Matlab or Octave and the computer hardware. The Psychtoolbox’s core routines provide access to the display frame buffer and color lookup table, allow synchronization with the vertical retrace, support millisecond timing, allow access to OpenGL commands, and facilitate the collection of observer responses. Ancillary routines support common needs like color space transformations and the QUEST threshold seeking algorithm.
