OS (e.g. Win10): MacOS Big Sur 11.1
PsychoPy version (e.g. 1.84.x): 2020.2.1
Standard Standalone? (y/n) If not then what?: Yes
What are you trying to achieve?:
In my experiment, participants must type a word. I want to record the key press duration for each key they press (i.e. how long each key is held down for). I have found documentation using .duration (Keyboard — PsychoPy v2021.2) but I cannot figure out how to implement this into my experiment to get a list of durations for each key press.
What did you try to make it work?:
I have added the following into a code component in my experiment:
Begin routine
duration=[]
Each frame
#keys2 = keyboardCom2.getKeys()
#for key in keys2:
# duration.append(key.duration)
keys2 = keyboardCom2.getKeys()
for key in keys2:
duration = key.duration
As you can see I have tried a few variations of the code above.
End routine
trials_2.addData("holdTimes", duration)
What specifically went wrong when you tried that?:
In the .csv file I get the column called ‘holdTimes’ but in the first row ‘’ is displayed, and the rows below it only show one value. I want a list of durations for every key press, not just one duration overall.
I’m sure I’m doing something slightly wrong with the code but I am struggling to find out what, so any help would be hugely appreciated.
