We have tried running the file and there are still some things we did not get them to work properly. In the first place, we want to establish exactly 10 CS + and 10 CS-, under the conditions previously mentioned. In the file, we have tried to change the maximum from <10 (previously established) to <11, trying to fix it, but the problem persisted (sometimes appear 7 CS + and 6 CS-, others 8 CS- and 6 CS +, 7 CS+ and 9 CS-, etc.). Our intention, as we have indicated, is that 10 CS + and 10 CS- must appear, randomly and with the restrictions previously indicated. Second, we have noticed that the ITIs may sometimes appear consecutively (eg lasting 3 s., others times lasting 6s, 8s, 9s, etc.). This should not happen because the variable was defined between 1 and 3 s.

In addition, we must note that we have selected "Present trials in this block = 20 times" in the tab "Looping" in "Block editor", and we donīt know if it can be behind those problems.

Finally, we would also like to add a final message indicating the completion of the experiment.

Thank you again for your help.

You are correct. The stimuli do not reach 10 presentations because block looping was limited. I've changed it to infinite looping.

On that note, in order to stop the looping and present an end message, I've set criteria in the block's When to Present tab: only present when total CS+ or CS- count is < 10.

I've also made other changes that will prevent your experiment from getting stuck and presenting ITIs consecutively. I've done this by adding rules to the ITI trial and removing a criterion from CS+ and CS- trials.

The experiment is almost finished, it works perfectly whether it responds slower than the previous time (Feedback not shown) or responds faster than the previous time (Feedback message is displayed). However, we have tried to program it so that the time limit to which the participant can respond is 2 sec. after the start of the tone, and in case of no response during this interval, continue to ITI (something similar to the situation of "if it responds slower than the previous time"). The problem is that sometimes, when the participant donīt press the space bar, the Feedback message is displayed.

On the other hand, we also want that, when the participant gives a correct response (faster than the previous one and the Feedback is presented), the feedback message stays on the screen for 2 seconds and the participant doesnīt have to press the bar to continue.

If we could fix this problem, the experiment would be ready. To do this, we upload a copy of the experiment in superlab, and the CS and tone used, so you can test it under the same conditions.

Thank you again for your help.
