Pavlovia Surveys feedback

Online experiments Pavlovia Surveys

Dear Pavlovia time,

Last week I ran a workshop at our faculty to introduce Pavlovia Surveys to starting PhD students. In the process, the following issues appeared and I wanted to share them, maybe you have some feedback on some of these:

  1. When setting up an HTML component, I used a Word to HTML converter to make sure our informed consent was nicely formatted on the page. However, I ran into issues with the survey breaking when I copy-pasted the output in html markup field. Could this have to do with size limitations on the input field here, as it does work as long as the markup is small enough (the converter produces extremely large HTML code)

  2. When using input validation on a radio button group for the informed consent (yes or no option), the validation worked in preview mode, but not in pilot or run mode. It should produce an error only when the user selects no, but it produces the same error for both the yes and no alternative. Only when I selected a lower survey version did the validation work.

  3. When using the single input - slider response, we noticed there was no option to put labels underneath the slider. We thought it would be helpful if the endpoints and middle value are marked (e.g., 0, 50 and 100 for a slider ranging 0 to 100).

Would be grateful for any feedback on these issues :slight_smile:

Hi.

  1. Did you click on “Clean” in wordhtml to simplify the html code? I standardly use this site for my PI sheets and haven’t come across this issue.

  2. I think that the key here is to include the block name in the expressions.

Hi wakecarter.

  1. Tried that as well and then it did work, leading me to suspect it might have to do with the allowed size of the HTML markup. Do you think this is something which could be indicated in the interface, like a message that says the maximum number of characters have been exceeded?
  2. Including the block indeed worked, but the phenomenon reversed :D. Not working in preview and old version of the survey, but it does work in the newest version

Another issue I just noticed: when I have a few sequential blocks, and I delete all except the first one, after saving and refreshing the blocks still show up in the flow view but they are empty and I don’t see how I can delete them. So I cannot complete the experiment because when I run it, it sees an empty block.

Thanks for your response!

Have you tested your size theory by splitting the html across two html questions? (To get the tags correct I would recommend pasting the two halves into wordhtml separately) It might be that there is something in the html causing the survey to fall over rather than a length issue.

I’ve come across the block deletion issue before and I’ll note this thread in the error report.
