Overall, the message of the story is that people learn languages according to different cognitive styles in different situations. The book is very dense and somewhat hard to read since lots of information is just thrown at you. If you really want to read this, then I suggest you keep a pen and paper or a highlight nearby to take notes.The authors use lots of scientific and linguistic jargon, which makes this book a bit inaccessible to everyday readers. It's not a "pop psych" book. They definitely know what they're talking about since they mention most of the major studies done on second language acquisition. Long story short, the book contains a lot of useful information, but it may be hard for an average, non-scientific and/or non-linguistic, person to read.For example, beforehand, I read some of the research studies that they quote, so I knew what they were talking about most of the time, but I have no linguistic background. When they delve deeper into the nitty-gritty linguistic terms, it takes a lot of processing to keep things straight.
