Arman,

It worked fine. I attached the current version experiment so you can take a look at it.

I added another sound to signalize to the subject that they avoided the shock successfully and limited the number of avoidance "trials" (blocks 2 and 3). These are working great as well.

However, I tried to present blocks 2 and 3 not only after 6 seconds, which is working, but also if two successful shuttles are achieved, which is not. This later rule I tried to count the number of successful shuttles in a correspondent parameter and limit the presentations of this parameter in a rule included in the block. Why is it not working?

Another problem is that, sometimes, the first time the virtual subject touches one of the grid if being computed as a successful shuttle, sometimes it is not. I couldn't figure it out why...

Thanks again!

1. Your rule checks for exactly 2 successful shuttles. It should be checking for at least 2 shuttles. Change "Parameter Successful shuttles = 2" to "Parameter Successful shuttles > 1". Also, at some point, you should be resetting the successful shuttles parameter.

2. Your shuttle trial needs to start off with a tag for Last Side Touched. Manually select "None". Then, adjust your successful shuttle rules like so:



3. You also need to take care of the case that the circle spawns on columns A or E. To do so, open the Grid trial - where you set initial position - and use the "Set Last Side Touched" rules after the tag position rules.

In the future, if you are attaching an experiment with media files, please create a .zip file via SuperLab by clicking File > Create an Experiment Package....

Hi!

I followed your instructions, but sometimes the same problems are happening: the "AA trial" block is running just once and "safety sound" is sometimes presented sometimes not. Can't see a pattern. Don't know exactly if is just the stimuli that is not being presented or if the shock is not being delayed as well. Kind of lost at this point....


Best regards!

Compare your successful shuttle rules. The organization in your criteria is faulty for "Successful shuttle to the left". Fixing this should help with the safety sound.

As for your "AA trial" block sometimes running just once, try to figure out the case in which this occurs. Do you never want this to be the case?

It worked. Amazing how fast you guys find an error...
I will think about the AA trial repetition and now start working on recording subjects' inputs...
Thanks a lot!
