OS : Windows 10 PsychoPy version : v2021.2.3 What are you trying to achieve?: This is my first time using python/psychopy builder so apologies if I’m missing some basic knowledge that would help me get started with this. I want to set up an experiment in which random sequences of 5 digits are pre…

Off the top of my head, I think you need event.clearEvents() in Begin Routine to clear the keyboard buffer.

Hi Search for online demos to find my digit span demo which generates sequences which start with 1-9 and then follows with random digits 0-9 with no doubles.

Hi There, There are many possible approaches but here are some handy functions and I believe wakes demo will show a nice implementation. To outline some of the basic functions to get started. You could have a spreadsheet with the column header “digits” and each row value corresponding to the digit…

Thank you! I tried setting it up as you described, but got this error message: TypeError: 'str' object does not support item assignment ##### Experiment ended. ##### I’m guessing it is because of this line? : thisExp.addData('new_digits', Digits) # store the shuffled digits to data file

Is this a local error or online? Please could you show the current code you are using? I don’t think that’s the line with the error.

I’m running it locally, I put this code into the ‘begin routine’ tab: Digits.split(",") # make a list of numbers shuffle(Digits) # shuffle the digits nDigits = len(Digits) # check how many digits thisExp.addData('new_digits', Digits) # store the shuffled digits to data file

Try digitList = Digits.split(",") # make a list of numbers shuffle(digitList) # shuffle the digits nDigits = len(digitList) # check how many digits thisExp.addData('new_digits', digitList) # store the shuffled digits to data file

Thank you, that prevented the error. I have managed to adapt your digit-span demo for my purposes now - thanks!! - One thing, I noticed that keyboard input was being recorded prior to the response collection screen (during select_digit). Once the response collection screen appears (trial), any keyb…
