Unable to run experiment due to 'KeyError'

Builder
1

Hello,

I am working on an experiment with two sections. In the first, participants see a string and then copy it. In the second, participants see a string and press ‘G’ or ‘N’ before moving on to the next string. The experiment was working at first when I ran it, but it stopped working after I made some changes to the entries for participant information that shows up at the start of the experiment. I got an error message that I pasted below, but I am not sure what the ‘KeyError’ means. I understand the alerts about the editable textbox component and the keyboard component conflicting, but the experiment was working fine even with those alerts before, so I’m mostly trying to figure out what the KeyError is. Any help would be appreciated, thank you!

KeyError: ‘participant’
Alert 4405:Editable textbox component AResponse and keyboard component A_resp in the same routine may compete for keypresses

Alert 4405:Editable textbox component C_Response and keyboard component C_String_Proceed in the same routine may compete for keypresses

Hello,

the error message tells you that psychopy detects two components which take keypresses as input. Separte the two components in two routines.

Best wishes Jens

Have you deleted participant from your expInfo dialogue box?

An editable textbox and a keyboard component in the same routine can work well so long as you are aware of the potential for conflict. For example you can use a keyboard component looking for return to end the routine.

I edited the dialogue box to add two other entries for participants to fill out, but I still have ‘participant’ there, it currently looks like this:

You’ve given participant a capital P.

7

Oh, do the other entries also need to be lowercase or is that only necessary for participant?

Only participant and (to a lesser extent) session since they are the defaults.

I see, thank you! I changed it and it works now.
