I am creating an experiment in which I want the participants to repeat the trial if they made an incorrect response until they get it right (correction trial).
I can handle it through the rule “if incorrect response, then restart the trial”, which is fine. At the same time, though, I would like to count first presentations only to determine whether a behavioral criterion has been reached. For example, if a participants responded correctly on 8 consecutive trials (first presentations only), then the program moves on to the next block. In addition, I need to record in the data file whether it is the first presentation or not. I think this can be accomplished through the parameters but so far I was not able to figure out how to do that.
