Language is my second language
I have no background in psychology. The highest level of scientific study I've done was Grade 12 Chemistry, Biology and Maths B, and that was almost ten years ago.
Nevertheless I found this incredibly easy to understand. It was extremely interesting, and the narrator was very engaging.
I have some issues with production, often they would repeat 30 seconds or a minute of narration.
I understand the complaint someone made about this being superficial, but is only meant to be an introductory guide, and I think it sets out to do that very well. It has in fact whet my appetite for more, and I intend to do some more detailed study into some areas raised by the book.
