Progress conditional on correct response

In my experiment, I’ll like to present 4 practice trials to participants, and obtain 100% correct responses before they move on to the actual trials. If accuracy <100%, a further 2 trials should be presented. If both trials are answered correctly, then participants will move on. If not, another 2 trials should be presented.

How can this be done? Thanks for your time.

This can be done. It is already (mostly) explained in the draft manual of SuperLab 4.0, which is nearly complete.

I will post (or email you) a PDF of the manual next Wednesday. Sorry for not being able to post it sooner due to the 4th of July holiday and me being out of town on Monday.
