I've read the Australian version first then read the American edition.
Major points were virtually identical except the fillers in between, Australian edition was more centred around multi-culturism, encouraging self awareness, sparking an interest in self development and communication. Where as the American edition was heavily focused on disparaging against new age or pseudo scientific medical practises as they cant or are difficult to be proven in a falsifiable scientific testing. The whole, "there are only black swans" falsifiability statement.
Though i thoroughly enjoyed reading them both, I found the way the American edition was written and portrayed kept my attention alot easier. however the study guides that accompany each book are completely different as in references to specific socio cultural relevance to the daily life's of the student. After completing both editions I found myself going back to the Australian edition due to one being in Australia and secondly it was more specific to the core material of what I am studying instead of convincing me that there are pseudo con artists.
My personal point is that no matter what, a hug is a placebo that can have major consequences on the treatment of patients due to oxytocin alone and the creation of new neural synaptic receptors, one needs the desire for specific neuropeptides to initially change desire to positive limbic (Paleomammalian Brain) development. If what a patient does or the charges responsible for there development can produce a positive disposition, then the very act of attention alone of focusing on there self awareness, also the catalyst reason, instead of overwhelming them with what there condition is, will have exponential qualities rather than informing purely cognitively.
Smile, Hug say a nice word then oxytocin and meditate me up Scotty.
