I am working on a project that has 7 levels with 10 trials per level and 4 events per trial. The subject is required to respond by touching the screen after the audio prompt. One of the levels (5) is not responding to a single touch, instead it requires that the subject touch the screen twice before the next event appears. I have already redone the whole program several times with no success. What is going on? Hisham had already told me that it was probably related to input. I have tried reworking this and have been unsuccessful. I have attached my experiment to see if anyone can help. At this point, I am on a time crunch since I am getting ready to work on my dissertation and need to get this resolved.
