Reply to "Does anyone know of an infographic or chart portrayal of physiological, psychological, emotional and developmental consequences of separation trauma by age?"

You might be able to create one, if you look at the work of Allan Schore.  He's a neuroscientist whose specialty is attachment, and the developmental stages a kid goes through, and what is happening neurologically if things go right vs. if it goes wrong.  

Also, there may be Kindertransport data you could mine?  Or Foster youth data?

In general, early separation is encoded in the right brain, as under age 2 or 3 the right brain is growing and developing much more actively and rapidly than the left.   R brain "certainties" of loss, pain, fear are persistent and very hard to rewire.
