Understanding the talks in Conferences and Workshops
This may seem strange at first, but one way I've found to understand an area better is to write in it.

Every area of any discipline has its own mini-language. It consists most obviously of specialized terminology---but there is also a certain structure and order to how people in that area prefer to give and receive information. There are also particular ways of understanding certain difficult concepts, especially abstract or nonobvious concepts.

Reading is obviously key, and it will help you understand the terminology. But to really climb into the heads of those who present in your area, you have to write. You'll then be forced to learn good ways to structure information and ways to understand difficult concepts---and discover how and why the other researchers in your area think and talk the way they do.
