Psychology

I am reading the book written by 張春興. It is hard to believe that this book has been published for thirteen years. I had never taken psychology course, but the content of the book looked so familiar to me. I am wondering all my readings related to psychology are indeed extracting and refering from this book. However, as I check the edition of the book, it is so scary that there is no other edition. This book is still in its first edition. I hope the auther can proceed his extraordinary work and add some materials to it.
