Pavlovia Surveys: Page-level timers and one-time random assignment without blocks/triggers?

[wakecarter]

1. You currently have one survey that shows both feedback elements. Personally I would show the feedback itself in PsychoPy, unless the rest of the survey is different). If you want to show one of two different surveys then put both in the flow and a loop around each with a variable nReps (e.g. highFeedback for one and 1 - highFeedback for the other)

2. Progress bar. You are currently setting it to 0 every frame.
   

   

I haven’t tried progress bars myself but what happens if you set it to t / 10 (so it reaches 1 at 10 seconds)?

Some notes on randomisation.

Wakefield's Daily Tips

Random vs Counterbalanced There are three main levels of randomisation that typically exist within an experiment. Random order of trials Random order of conditions Random assignment to groups Order of trials is set either by setting the loop to sequential, random or fullRandom. When the loop is sequential, then the trials themselves could be an a specific order (e.g. of increasing difficulty), a pre-randomised order or a shuffled order of selected rows. Having a random order has the advantage…

Counterbalancing online Random allocation to groups is easy, but by it’s very nature can easily result in unbalanced group sizes. For counterbalancing, the allocation needs to take into account the allocation of other participants. I have written three external tools which offer solutions to this problem. Participant IDs for Pavlovia This tool adds a consecutive value for participant to the study URL which can be used to systematically allocate participants to different groups using the modu…
