Freezing the experiment by pressing the 'enter' key

If this template helps then use it. If not then just delete and start from scratch.

What are you trying to achieve?: I would like for the entire length of the experiment, in case the subject presses the ‘enter’ key, the experiment will stop and a slide will appear in the style of ‘the experiment is paused, thank you’. Is there such a possibility?

I’m not interested in completely exiting the experiment screen like with the ‘escape’ key

Hello,

yes that is possible. Add “return” as a possible response key, add “feedback”-routine, insert a code-component at the Begin routine tab of your “feedback”-routine, check if “return” has been pressed, present your break-screen, otherwise skip your “feedback”-routine.

But the experiment is stuck when it comes to this routine

Hello,

you need to check whether there was a response in your trial otherwise your experiment crashes with:

if 'return' in key_resp.keys:

TypeError: argument of type ‘NoneType’ is not iterable

So change your code to

if key_resp.keys:
    if 'return' in key_resp.keys:
        msg = "break"
else:
    continueRoutine = False

Initialize msg in the Begin Experiment tab with

msg = " oops"

I always initialize variables, especially feedback variables to check the if-else construction. Set $msg in the text-parameter of the feedback text-component to set every repeat
