A Matlab & Psychtoolbox version of STOP-IT.
You will have to install Matlab and psychtoolbox (psychtoolbox.org) to run the code.
This version of the program allows you to run a stop-signal task, a go/no-go task, a stop-change task, or a double-response task. Note that there are some differences (e.g. go and stop stimuli) with the original version of STOP-IT.
R code to analyze the data is also included. The integration method is used to estimate SSRT (see Verbruggen, Chambers, & Logan, 2013).
