The importance of social intimacy for individual growth.

In my last post I wrote something to the effect that our lives are like dances between self-aggrandizement and self-effacement, between self-expressive individuality and the need to pay homage to our collectivities, those groups and associations upon which we completely depend for life and prosperity.
All of us are caught in a tango of cognitive dissonance. On the one hand we need to express ourselves as individuals while not turning our noses up at our collectivities (societies, nations, families, workplaces, etc.). We ignore our collectivities at our own peril. It's built into our genes. There is research that demonstrates clearly the importance social connection is to us. In 1945 Rene Spitz conducted research comparing children raised in orphanages and those raised with their mothers in prison. After four years, a quarter of the orphanage children were dead, the others seriously socially impaired. By contrast, those children raised by their mothers in prison were fine. The difference between the two groups of children was the amount of daily physical and emotional contact they experienced. Children in prison had lots of physical and emotional contact, those in orphanages very little sporadic attention. The sparse research done on feral children supports the idea that without human intimate contact we do not fully develop as humans. Our very intelligence (IQ) is dependent on social contact. A longitudinal study conducted by Skeels and Dye (in Roberta Berns, 2009; Shackne: http://www.schackne.com/Nurture.htm) starting in the 1930s and concluding in 1966 found that two children removed from an orphanage as hopelessly retarded and were moved to an adult facility that cared for retarded adults substantially improved within a few months and displayed increased sociability and intelligence. They subsequently moved 13 children to the adult facility and all of them improved dramatically. In a follow up study done 25 years later, "they found that all of these "hopelessly retarded" children had grown up to live normal and productive lives. Some even made it to college and became professionals." (Shackne) In contrast, the control group of children left in the orphanage for 'retarded' children experienced no such improvement. More recently a study found the same kind of results with Romanian children confined to orphanages and moved to foster homes.(http://www.guardian.co.uk/science/2006/feb/18/medicineandhealth.lifeandhealth/print)
So we are by definition social animals, so much so that in the absence of social contact we die or are severely cognitively and physically impaired, sometimes permanently. We are beholden to our societies for all that we are. As Ernest Becker points out repeatedly in his books The Denial of Death and Escape from Evil, our societies are the source of all power. It behooves us to keep a watchful eye out to make sure we don't get irretrievably cut off from this source of power by exhibiting too much individuality. The glue that holds us together in societies is tested every day in every aspect of our lives. Shame, guilt, embarrassment and opprobrium are institutions that maintain strong social ties as much as love does. And we dance. We try a little self-expression and see how that goes. We try a little more and see how that goes. We test the limits of individual possibility. We retreat. We get up on the dance floor but soon sit down if we notice people noticing us too much. Our language is replete with mechanisms for enforcing and re-enforcing social ties and for allowing the expression of individuality without compromising our social connections. But more on that later.
