Hello,

I wanted to ask if anyone knows how to add a “I am not a robot” tick box to the start of a pavlovia survey. I am not planning on inserting qualtrics/google form links before it (consent form will be within the pavlovia survey).

Is this even possible? After the survey the participants will be directed to a cognitive task, should I add a captcha type test in PsychoPy builder before the main task commences instead? Any advice is appreciated.

Many thanks,  
Paulina

Hi,

This is on our to-do list, and should be fairly easy (for an expert developer). I found this link.

However, I don’t think it is likely to be added soon. I could try adding it to the VESPR Study Portal if I can find the relevant PHP code

Hello,

Have there been any updates on this since 2023? If not, does anyone have any suggestions on how to prevent scam/bots from entering the survey?

Cheers.

Adding a catch trial/prompt is the best way. Then just check responses and don’t assign credit to bad actors. Covers for bots or lazy/no-effort participants.
