Description of the problem: I am transferring my experiment to online experiment. The Psychopy builder mode also does not support the “keypress duration” function, only the “keypress frequency” and “keypress reaction time” functions. While I have been able to add the “keypress duration” function …

Hi Carine, I was trying to do the exact same thing but I could not yet find how to store keypress duration too. Could you share your code with me? I would really appreciate it! :slight_smile:

Hello everyone, Just wondering if there is a trivial way to record each key press duration from the keyboard component on PsychoJs (In PsychoPy: tDown: the time the key went down in absolute time)? Not sure if @Carine and @pinar have found a way around this? Cheers Josh

Hi @Josh_Khoo I ended up using two key presses to indicate an interval time: one to start and one to end the estimated duration. Then I just substracted t_press for key1 from key2. Therefore I don’t have a code for storing keypress duration, unfortunately.

Hi @pinar , Thanks for the reply. Unfortunately that is not what I’m looking for. Would @apitiot be able to help? Cheers, Josh

Thanks for pointing to the link! @milsandhills

Not sure if you already figured this out, but this link should help: Measuring key lift time relative to stimulus onset
