Hi Noe,
You can get the reading times by subtracting the timestamps of the two Key elements, named " " and " 2" in the results file. For example, you have a reading time of 350ms for item 24 and a reading time of 396ms for item 33.
If you know R, you can take a look at this R script from the tutorial to get a sense of how to automatize RT calculation.
One suggestion for your script: you could .disable your first Key element immediately after its .wait command, this way your results file wouldn’t report two keypress events on the wait of the second Key element (at that point, your first Key element is still active, which is why the single keypress gets detected twice).
