Hello! I’m trying to make a feedback loop saying “Too Slow!” only when they take longer than 1.5 seconds to respond, but it keeps crashing and I’m new to this so would appreciate some help :slight_smile: This is the code I’ve put in the begin routine tab: (my text response component is called respo…

Hello Hannah the following code should work, at least it worked for me: msg = " " if (response.rt > 1.5): msg = "too slow" continueRoutine = True else: continueRoutine = False put this in the Begin Routine tab. Place the code-element above your text-element, displaying the feedback me…

I suspect that you are storing all responses in your keyboard component. That would make response1.rt a list. For the most recent rt you need response1[-1].rt Alternatively, change the routine to only store one response. However, you also don’t need continueRoutine=True, just have if response1[-1…

Hello wakecarter’s solution is more elegant and parsimonious. And he found the error that I missed. Best Jens

[image] JensBoelte: msg = " " Hi I encountered the error of ‘TypeError: ‘Keyboard’ object does not support indexing’ when implementing similar codes if respKey[-1].rt <= 1.5: msg="too slow" in the Begin Routine. Any suggestion? Thanks!

Sorry – does respKey.rt[-1] work when storing all keyboard responses? Also, I think you want >= 1.5 for slow RTs.

Using respKey.rt[-1] gave me another error message of “IndexError: list index out of range”, any idea? thanks ps. thanks for noticing it, I used <=1.5 to debug to show the ‘too slow’ faster :slight_smile:

My attempts have been revised here (sorry not yet successful but found some consistent errors): I tried moving this section of code from Begin Routine to Each Frame, but I still get the error ‘TypeError: ‘Keyboard’ object does not support indexing’ when I use respKey[-1].rt (also try [0], same error…

What is your keyboard component called? It is in the previous routine, isn’t it? Is it saving one key or all keys? How does the previous routine end?

the keyboard component is ‘respKey’. Perhaps the issue is that the code (tooSlow, see image below) is located in the current response (resp) routine? I store the last key in the respKey properties and allow three letters that correspond to the $correctAns. The text component used to display the ‘Re…

Hello, the feedback has to follow the response. Put your feedback in routine following your response routine. Best wishes Jens

This post might help with getting RTs from keyboard lists.
