About FLXLab

FLXLab is a program for conducting computer-based experiments in psychology and related fields. It can present stimuli in the form of graphics, text, or sound, and can record responses to those stimuli, either manual (i.e., pressing a key) or verbal.

FLXLab is currently available for the Windows, OS X, and Linux operating systems.

I no longer have time to actively maintain or support FLXLab. As of this date, FLXLab should still work for current versions of Windows, but the Linux and Mac versions may not work properly.
April 5 2011
Version 2.5alpha released! This version fixes problems with FLXLab running under Windows 7, as well as some minor issues with playing sound files. For the time being, this version is only supported for Windows, as it fixes Windows-specific problems. If you are a Mac or Linux user, you can continue to use version 2.4.
February 12 2010
Version 2.4 released! This version fully integrates Mac support, fixes a few bugs, adds a few small features, and provides better documentation for using fonts.
September 11 2009
Initial Mac port of FLXLab released! Finally, you can run FLXLab on a Mac, too. This port doesn't provide support for playing or recording sounds (hopefully that will be added in future releases), but otherwise it is a full-featured version of the program. The port required a number of minor changes to the source code and makefiles, so for now a separate source distribution is available for the Mac version.

Version 2.3 released! This version provides several new features, fixes some bugs in the previous version, and includes a new demo illustrating how you can do IAT (implicit association test) experiments. It also includes documentation for writing your own modules, which is useful if you want to be able to use FLXLab with a particular piece of specialized hardware. Finally, some major portions of the base program have been redesigned to make them simpler and provide a better foundation for improving the program.
October 10 2008
Version 2.2 released! This version fixes a few bugs in version 2.1, adds a couple new features, and adds a couple new demos.
August 14 2008
Version 2.1 released! This version introduces relatively few changes from the perspective of the user, other than a reorganization of the documentation. On the inside, however, it's a whole new program - major changes in the way fonts are supported, and the Windows version is now built using MinGW, which means that the gcc compiler is used for both Windows and Linux versions.
July 11 2008
A new installer package for version 2.0 is now available for use with Windows Vista.
November 11 2007
Version 2.0 released! Major new features include the ability to create custom dialog boxes, new commands for constructing and randomizing stimulus lists, and support for displaying JPG images.
July 21 2006
Version 1.9 released! The most significant change is the ability to use almost any font installed on a system, rather than just the fonts distributed with FLXLab.
April 22 2005
Version 1.7 released! The most significant change is support for joysticks and game controllers in the Windows version (this feature doesn't work in Linux yet).
April 5 2005
Version 1.6 released! Major changes include the ability to create and edit scripts from the start screen, the introduction of counters, and an "If" construct for conditional execution of commands.
August 11 2004
Version 1.0 released!
