PsychoPy version (2021.1.4):
**Standard Standalone? (y)
What are you trying to achieve?:
I am using Builder and the included Cedrus component. The “store correct” option is enabled.
The experiment consists of a few tasks. Within each task, there are repeats of the same trial, ie they are built as looped routines.
The experiment works well, except when there is no response given (ie, no Cedrus key is pressed) in the first instance of the trial.
When there is no response in the first trial, PsychoPy would exit with the error
“…pyxid_impl.py”, line 371, in getattr
return getattr(self._impl, attrname)
AttributeError: ‘NoneType’ object has no attribute ‘corr’
However, if there is a response in the first trial, the experiment would continue even when there are no responses in subsequent trials.
What did you try to make it work?:
I tried unchecking the “store correct” box. It did not prevent the error.
What can I do to bypass this problem? If this is not fixed, I run the risk that participants will have to repeat previous tasks because they fail to press a button in the first trial of the last task.
