The Psychtoolbox is popular. As of October 2006, Psychtoolbox-2 has been downloaded thirty thousand times: 24,324 Windows and 8,743 Mac OS 9. Psychtoolbox-3 for Mac OSX was downloaded 1,832 times before 22 September 2006. The current count, since 22 September 2006, of registered unique installations of Psychtoolbox-3 appears below. The Psychtoolbox [[PsychtoolboxForum forum]] has over 1500 members and about 4 messages a day. Principal investigators and their collaborators have identified at least 127 [[http://psychtoolbox.org/PTB-3/grants.html grant]]-supported projects that use it.

The attraction of using computer displays for visual psychophysics is that they allow software specification of the stimulus. Programs to run experiments are often written in a low-level language (e.g. C or Pascal) to achieve full control of the hardware for precise stimulus display. Although these low-level languages provide power and flexibility, they are not conducive to rapid program development. Interpreted languages (e.g. BASIC, LISP, Mathematica, and Matlab) are abstracted from hardware details and provide friendlier development environments, but don't provide the hardware control needed for precise stimulus display. The Psychophysics Toolbox is a software package that adds this capability to the Matlab and Octave application on Macintosh, Linux and Windows computers (we will only mention Matlab for the remainder of this text, but statements mostly apply to Octave as well).

Additions:
The Matlab & Psychtoolbox environment is flexible yet relatively easy to learn. Canned experimental programs fail because they usually can't do a really new experiment. For that you need the expressive scope of a full-fledged computer language, such as ""C"" or Matlab. Matlab is a particularly good language for running laboratory experiments. Even for experienced programmers, three features of Matlab greatly speed the development cycle over other languages. Matlab has a rich library of high-level functions available to do math and plotting. It operates on arrays and images as named variables. And it is interactive, so that one can type 1+1 and immediately see the answer 2, which is invaluable when developing laboratory software to run experiments.
Brand-new users who've never programmed before will find that they're learning three things when they start using the toolbox: Matlab, how to create stimuli and measure responses, and how to organize an experiment. There's almost no overlap between those three topics. The included demos illustrate how many common tasks may be accomplished (type ""help PsychDemos""). For learning the language, many people say they liked the Matlab manual. Others skipped the manual and learned by trial and error. Everyone uses Matlab's help feature frequently. It's one of Matlab's best features and we have tried to follow their conventions with the toolbox routines.

These numbers are automatically updated, based on our online counting and cover most downloads and updates since the counting started at 22 September 2006. They are a lower bound on the real number of installations, because our still-slightly-buggy counting scripts occasionally miss a few.
