Hi Katy,
In the end, I had to remove all interactive parts from the experiment, mainly a slider that I had added to every trial. A colleague of mine suggested having a screenshot of a slider and asking participants to respond using the 1-5 keys on the keyboard. It’s a rough fix, but it works…
Sorry I couldnt be of more help… I don’t think Pavlovia is very compatible with interactive experiments, it seems to work best with short “slideshow” type designs.
