Usually, when I think about working on things outside of sessions, researching is not what comes to mind. I consider working on things to be employing the skills you learn in therapy, and processing and reflecting on things you talked about in therapy. It's also becoming more aware of yourself and your reactions in between sessions. Just learning about the mode of therapy you're doing really doesn't do much in the way of helping you process what is going on with you specifically. Maybe, if you need specific tasks to work on in between sessions, you could ask your T for some suggestions.
