Ok, I picked this book up from the Saylor Academy's Introduction to Psychology course, as I was fascinated by the subject, and decided to self study. This means that I am not a psychologist, so I would rather not comment on (my perception of) the content itself, but I will comment on what features from the book I liked, and what I got from it.
Now, first things first, the Goodreads database is wrong. This book is not 480 pages, it's about 800 pages (the version you can find from MIT OCW if you google the name of the book and the author's name is about 860 pages, and the saylor version is 780). Granted, some pages are images, but still, the book was much bigger than I originally thought. I am saying it as a warning to people who, like me, are looking for a quick introductory book on psychology. It doesn't feel quick, and at times, it's so much packed with information, that, unless you use notetaking software (I use onenote) or anything else to take notes, and regularly revise them, it's going to feel overwhelmingly dense.
Well, having said the above, there were several things that I liked about this book. First of all, I found several chapters particularly interesting, including the one on the brain and the nervous system, the one on consciousness and the one on sensation and perception. I also liked the mini sections called "Research Focus" and "Psychology in Real Life" that described what people are working on, or situations in real life that psychological findings where particularly useful.
Another chapter of the book that deserves mention is the one on learning. I didn't learn too much from that particular chapter, since I had already learnt much of the information within from the Coursera "Learn how to learn" course, but it served as interesting revision material, and a good reference, proving that much of what you learn is solid documented scientific evidence.
I can't say much more about the book, since I haven't read many more on the subject, but it was a good read for me overall.
