The exe-version of STOP-IT (Verbruggen, Logan, & Stevens, 2008) was developed for computers running Windows 2000/XP, but users have reported that I can be installed on Windows 7 & 10 as well.
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 (although it should be noted that this version uses the mean method to estimate SSRT; see Verbruggen, Chambers, & Logan, 2013, in which we discuss some problems with this method).
**Additional notes:**
- 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.
