Isn't there a developmental window that basically closes (due to brain development) after which it's not even possible for the child to ever really have the biological abilityto form normal emotional relationships and attachments? Like by teenage years, it's way, way too late and any adoptive parent who expects even gratitude as they understand it, let alone a grateful child clinging to them as a father or mother figure, is going to be very,very disappointed. I know how many of those Russian adoptions have gone south and it seems to be a lot with religious families who have a high expectation that 'all you need is love' which is entirely untrue, you dumb hippy shits, when you're dealing with people who lacked the correct stimuli at the appropriate junctures and whose cognitive abilities are simply differently fucked as result.
I recall that abused child
Genie who was the subject of a lot of study way back in the 1970s and they basically thought then that the fact she was never spoken to and left in the dark alone until the age of 13 totally nullified any chance of her ever properly learning language despite being shown to be actually quite intelligent. after rescue. She could learn words mbut never master a semblence of grammatical structure. Something to do with the plasticity of the brain, or rather lack of it after a point. Language and various other stuff needs to be developed within a timeframe or the kid is developmentally fucked for life.
I believe this is why in the UK, there is now a focus on getting babies out from neglectful junkie/alkie/waster parents who neglect them before the age of six months or so, because if they leave it any longer, the lack of stimulus in those early months is known now to affect their cognitive and social abilities in a way that will likely affect their entire life.
Anyone have any info to correct any of the above, please chime in.
