Google Captcha as Study Element

trig

Hi,

has anyone ever tried to implement a Google Captcha as one study element to prevent bots from taking part in your study? I guess the implementation would not be overly difficult (e.g., with external-html in jspsych), but I am struggling with the domain/host thing when trying to generate a Google Captcha. Would that be the URL of the JATOS server?

Thanks for any pointers.

Hi @trig ,

Although I'm not familiar with the exact procedure, installing a Captcha at least requires an API key for the site. In this case, the site would indeed be the JATOS server. This means that in order to install a Captcha you would need to host your own JATOS server. On MindProbe, for example, this wouldn't be possible.

You could also considering implementing a basic Captcha-like screen yourself. For example, if you show a sketchpad with a picture of a Capybara and then ask people to indicate the name of the animal in the picture, a bot won't be very likely to pass this.
