It works with dads too, but they did the experiment for 3 minutes.
I can't see why it would be especially different if the father has a close relationship with the baby normally and the baby is used to a lot more responsiveness from him. My wife and I have changed working patterns a few times since my daughter was born, but I've found that when I was the one who spent a lot of time at home with her, I was often the one she would run to if she was upset or hurt and her mother was also in the room. One of the things I'm very grateful for is that my wife has never been defensive about her role and has always treated me as an equal partner in raising the kids. It probably sounds like a non-issue to be worried about, but it meant a lot to me.
