This software may be freely distributed only with all original files included in this release. It may not be sold and no fee of any kind may be charged in association with its distribution.

This is the initial release of a collection of paradigms and libraries for running psychology experiments on the Macintosh family of microcomputers. Currently, three paradigms, RSVP, PAIR, and MEMO are included. For each paradigm there is a compiled version, a sample input file (*.ecl), a header file (*.hdr) listing all parameters that may be altered by the experimenter, associated stimulus files where used, and a User's Guide. In addition there is an ECL User's Guide and a piece of propaganda (all manuals are in text only format and can be read with your favorite word processor or within any of the paradigms). Each paradigm also includes the THINK C 4.0 project, the resource file, and C sources. Four C libraries common to all of the paradigms are also included: XT1.lib, XT2.lib, ECL.lib, and macExp.lib; and two C header files: symbol.h and macExp.h. These files should be placed in appropriate folders in your THINK C folder. Eventually source code for ECL.lib and macExp.lib will also be made publicly available. The two XT libraries were created using Programmer's Extender by Invention Software, version 3.5 Copyright 1990 -- therefore these libraries may only be used in conjunction with an ECL paradigm.

At the current time several caveats are in order:

- Timing off of the keyboard or mouse is accurate only to 1/60.15 of a second. In order to achieve this accuracy AppleTalk and MultiFinder should be turned off and the program should be run from a hard disk drive.

- Picts and pict resources are drawn into offscreen pixmaps and then are transferred to the display. Therefore trials with many pictures (particularly 8 bit and full screen) make require a large amount of RAM to work.

- The built-in text editor can not handles files larger than 32K.

- When recompiling the projects it is likely that THINK C will not be able to find the libraries. To fix this, simply Remove each library in turn and then Add... them from the appropriate locations.

- This software has NEVER been tested with Macintosh System 7.0.
