Keyboard reaction time start point

Hi People,
I built an experiment in the builder (no coding) and I would like to know the standard start point of the reaction time interval.
Is it counted since the beginning of the routine or since the time point where the keyboard element is inserted?

Thank you.

Hi @andresimi, this is taken from the Keyboard documentation:

time will be taken from the start of keyboard checking (e.g. if the keyboard was initiated 2 seconds into the trial and a key was pressed 3.2s into the trials the response time will be recorded as 1.2s).

So the RT you get will start from the onset of the keyboard component in your routine.

Thank you very much!
