|dc.description.abstract||The stop-signal paradigm is a useful tool for the investigation of response inhibition (for a review, see Verbruggen & Logan, 2008). In 2008, Gordon Logan, Michael Stevens and Frederick Verbruggen 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.
STOP-IT for Windows 2000/XP and can be download here. The main advantage of STOP-IT is that 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.
- We strongly advise users to read the instruction file, which can be found in the Startup folder, after installing the program.
- You need administrator rights to run STOP-IT; otherwise, the program cannot write the data to the output folder.
- In the 2008 STOP-IT paper, it is mentioned that “The stimulus remains on the screen until subjects respond, or until 1,250 msec (i.e., the maximal RT) have elapsed.” (p.481). However, in STOP-IT, the stimulus remains on the screen for 1,250 msec, regardless of the latency of the response.||en_GB
