What are you trying to achieve?:
Reaction time in milliseconds (e.g., 300.34)
This is an letter-sequence protocol, with
Essentially I am trying to obtain the reaction time in milliseconds from:
Cue STARTED to Cue STOPPED
Probe STARTED to Probe STOPPED
My response element is labelled key_resp, allowing left (incorrect) and right (correct) arrows to be pressed.
What did you try to make it work?:
Based on a previous post (How can I measure reaction time in milliseconds?), I put a code component at the beginning of a routine, with the following line in the End Routine tab:
thisExp.addData('key_resp.RT in ms', key_resp.rt * 1000)
What specifically went wrong when you tried that?:
In the Excel data file reaction time comes up as: [1.063594] for each response. I am guessing that this is in the absolute seconds/time since initiation of the experiment.
I wondered if there was a way to provide feedback as a percentage of correct responses after a certain amount of loops (e.g., %correct 20 loops into the experiment). If anybody has any suggestions I would be incredibly grateful.
