A more up-to-date and complete treatment of these exact topics can be found in the recently-published book, _Make it Stick: The Science of Successful Learning_ (http://www.amazon.com/dp/0674729013/). For those that have already immersed themselves in spaced repetition techniques via Anki, SuperMemo, Mnemosyne, etc., some of the material in the book will be review. But there is a wealth of useful information for both students and lifelong learners. In addition to that, the intertwined, real-life case studies and anecdotes drive home the points. And lest my comments come off like a back-cover endorsement, I will say that I was a bit disappointed that the authors seemed to have little awareness of SRS' momentum on the Internet with the aforementioned programs. For example, even though the book spends quite a bit of time discussing spaced repetition and flashcards, it never once mentions Anki, SuperMemo, or other popular SRS software. Aside from that, it's still an excellent book.
