- A C library for programming cognitive experiments on Windows
The stop-signal paradigm is a useful tool for the investigation of response inhibition. Recently, Frederick Verbruggen, Gordon Logan, and I developed a free program, called STOP-IT, for running the stop-signal task.
STOP-IT can be installed on computers running Windows 2000/XP, is available under the GNU General Public License and can be download here.
The main advantage of STOP-IT is that it is a precompiled executable and for basic use there is no need for additional programming. In addition, we also offer an analyzing program, called ANALYZE-IT. ANALYZE-IT can also be used out of the box and is automatically installed during the installation of STOP-IT. This second program allows users to estimate SSRT for every subject and it will calculate the means for all dependent variables of interest.
