Hi bissera,
Thanks for providing more info. Based on your description, I think there are two ways of achieving (most of) what you want:
1. Specify the audio, fixation cross, text options, and a keypress response within the same trial. Use the custom option for specifying the location of stimuli and set auto_advance to true. When you create your keypress response, make sure to set multiple to false. For the audio stimulus, set barrier to true. If you'd like the fixation cross to disappear once the audio is finished playing, you can set its duration to the length of the audio clip. See below for an example of how you can set up this trial template.
We discovered a bug in the process of testing this solution, so note that for now, defining the 'whitelist' property for keypress responses will result in the study getting stuck. But this issue will be fixed in the next week or so, now that we are aware of it.
Randomizing the location of your text options will be an issue with this solution, however, as you've discovered.
2. Specify the audio, fixation cross, text options, and a choice response within the same trial. Again, make sure that barrier is set to true for the audio stimulus. For the choice response, make sure that key_only is true and key_mapping is defined. As I mentioned before, setting instruction to "" will suppress the instructions. You can randomize the location of the text options with the "locations": "random" property of the choice response.
I think this almost gets you exactly what you want, aside from the 'Press (defined key)' labels underneath the choice options. There shouldn't be any clickable buttons using this approach.
Please report back if either of these solutions work for you. If not, we can try to troubleshoot any continued issues you are having.
Best,
Rachel
