Thanks for your response! We don't currently have any software and are trying to work out which software would be best for what we are trying to do. So unfortunately we don't have any files to send to you at the moment - we are just trying to figure out what would be possible with this software to see whether or not it would suit our needs. I am new to using experiments, but I hope I manage to clarify things a bit more below.

Participants will be given some information to read and then will be asked to make a judgment about what they have read (on a likert scale - so this will just be a number). Following this, the judgment that each participant has made will need to be made visible to the other participants in the room. Ideally, this would happen by each participant seeing a screen (following making their own response) showing the responses that every participant in the room has made (including their own). So, this screen would appear the same for every participant in the room. I imagine this being in the format of each computer being assigned a letter, and this screen showing the letter of each computer paired with the judgment that has been made by the participant sat at that computer.

We will be using computers in a computer lab at University so they are connected through the University's central server but I'm not sure other than that. Not sure about numbers yet but it should be around 8 participants in the room at a time. In each session, all participants in that session will be exposed to the same treatments. All the computers would be using the same MediaLab file.
