I am doing a research in a field of psychology and I would like to do almost the same research (just with different groups) as one other published research. I can make similar research but actually I want to compare my results with already existing ones.
The thing is, that researchers made one simple application, more like a game. In their article they put a link for that game but if I want to use their game in my research I need to have theirs other application for recording each test session. I know for sure that I will ask them to use one part of application but if it's rational, I would like to ask them and use the whole game and the other application for the data collecting.
I know that this is more individual question, but I would like to know what is the common practice in computer science. Do people usually/ rarely ask someones applications/ programs for they own research? Unfortunately, I don't have a time to collaborate with someone in computer science to make other similar game. And even if I had a time I wouldn't be able to exactly compare the results with that published research which I would like to do. Anyway, I don't know the researchers but I thought to send them an e-mail to ask them.
