Only 1 repetition of each stimulus and no correct response
I've been struggling with some aspects of my experiment (I'm fairly new to OS). This is the thing, I need to play an audio file after which the participants need to answer 2 questions. The thing is that this is a sociophonetic perception test, so I need to know the participants' thoughts about certain features of the audio, which means there is no correct response.
The problem: I need to play each audio once and the participants need to answer with "yes" or "no" to the questions I asked. When defining the variables I do this (and I can see where the problem is in this part):
Now, I do this because I need each audio to be played only once before each question, but if I do this, the logged responses are "s,s" for audio a, "n,n" for audio b and no logged response for audio c. If I do a full factorial design, each audio is played multiple times (which is not the idea).
Another problem is that, as I mentioned before, there are no correct responses. I just need all of them to be logged. This may sound a bit silly in an experiment with only two possible responses per question, but this is only the first part of my study and I will have to create a new one in which a single question can have 6 possible answers (and, again, I need to log them all, as none of them is correct, but each element provides specific information). So, whatever orientation you can give me here will definitely help me when I create the next experiment.
Another important thing you should know is that this experiment (and the following ones) will be executed online (with OSWeb). So, please, share solutions, options and thoughts that are supported by OSWeb (I recently learned that some features can't be applied to online experiments).
Thanks in advance for your help.
