Welcome to the PsyScope Home Page. PsyScope is an interactive graphic system for experimental design and control on the Macintosh. PsyScope development has ceased and the program is not updated for new versions of the operating system. However, it appears to be largely compatible with all Mac systems from OS7 to OS9 and virtually all versions of Macintosh hardware. There is no user support, but users can exchange insights over the info-psyscope@psyscope.psy.cmu.edu mailing list.

Despite these problems, until E-Prime for the Macintosh becomes available, PsyScope remains as possibly the best way to build experiments on the Macintosh.
