We are working on an experiment including the Approach Avoid Task (AAT) into a larger experiment. We were able to put the AAT into the experiment and we haven't seemed to be having any problems until recently. We are not sure if it is a computer issue or a coding issue and we can't seem to find any errors in the code for either the edited sequence generator, which we shortened because we only include 40 pictures, or the full code.
The main issue that happens is occasionally, about every 3 experiments, the experiment will get stuck and only displays a blank screen right before the AAT. We can use "Cntrl+B" to skip to the AAT but it doesn't always show all of the pictures. I believe this means that the edited Sequence generator may be at fault but his only seems to happen on one of the two conditions from what we have tested. If at all possible could someone give a quick look over our sequence generator code and see if there or any issues or let us know if they have experienced similar problems and how they fixed it.
Thank you for the assistance.
