Using Pavlovia Survey Responses in Experiments

[JuleSchilling]

Dear all,

I watched the YouTube tutorial “Using Pavlovia Survey Responses in Experiments”. My ultimate goal is to show certain stimuli depending on the gender of participants (i.e., if you selected “female” show “female.png”).

However, as I am rather new to Pavlovia, I tried to start with the procedure as shown in the video. Thus, to display the age of participants. I got the following error code when I tried to run the experiment online " * TypeError: Cannot read properties of undefined (reading ‘_overallSurveyResults’)".

Thus, apparently the “$info_survey._overallSurveyResults[‘block1/age’]” function does not store the results of the survey, or at least not of my age variable.

I am beyond grateful for any advice! Thanks a lot in advance!

Where did you get the code ._overallSurveyResults from?

Try surveyResponse = info_survey.getResponse() and then surveyResponse['block_1/age']

PsychoPy Survey Component demo (embedding surveys in experiments)

As of PsychoPy 2023.1.1, surveys can be embedded in online PsychoPy experiments, which gives a step change in the level of functionality available. I’ve just made my survey test public so you can try it and fork it. Survey Test code | try it Surveys can be selected using the Survey ID (so they always run the latest version) of Survey Model File (so they protected from changes to the online version). The results of each survey are saved to the PsychoPy data file. However, if you want to acces…

Thanks a lot for your fast reply and help! I got the code from the PsychoPy YouTube tutorial.

I created a new experiment to keep things as simple as possible. Again, I just tried to display what was typed into a simple single line input question.
You can see my example study here: Jule Schilling / test_psychopy · GitLab

I tried to run surveyResponse = survey.getResponse() as a custom code and $surveyResponse['block_1/question2'] for the textbox to display the answer but I got the following error code: * TypeError: Cannot read properties of undefined (reading ‘block_1/question2’).

It seems to me that the answers of the survey are not saved, although the total java script for the study looks fine to me.

Is your textbox set to update every repeat or is it constant? The former is correct.

[JuleSchilling]

When I change it to every repeat I get this error code: * TypeError: undefined is not an object (evaluating ‘survey.getResponse’)

@JuleSchilling

TypeError: undefined is not an object (evaluating ‘survey.getResponse’)

What is the name of your survey component?

[JuleSchilling]

survey

[wakecarter]

What tab is surveyResponse = survey.getResponse() in? It needs to run after the survey.

[JuleSchilling]

It is in the next tab after the survey.

[wakecarter]

In the Begin Routine tab?

[JuleSchilling]

yes

I’ve just had a look at your Builder file.

Wakefield's Daily Tips

Code components go at the top When you add components to a routine they will, by default, appear in the order you create them. This is also, however, the order in which they get processed. I recommend that when you create a code component you move it to the top of the routine unless you have a specific reason why it should be lower down. The main reason for this is that it means the code in the Begin Routine tab is processed before any “set every repeat” parameters are set in other components. …
