The replication study has been programmed in Inquisit v. 3. You can download a trial version (no data recording) from [www.millisecond.com.][1]
Under the Files tab you'll find all necessary files to execute the script.
After you installed Inquisit, save all files in the same directory in your hard drive and execute AMP.replic.exe. The study session will start. Skip blocks with ctrl+b and quit the procedure with ctrl+q.
Have fun :-)
