At birth, the newborn shows no attachment but simple dependence. It is easy to prove: the child indiscriminately reacts to human signals, scans for patterns and motions, enjoys soft, high pitched voices and cooing, soothing sounds. Attachment starts physiologically in the fourth week. The child turns clearly towards his mother’s voice, ignoring others. He begins to develop a social smile, which is easily distinguishable from his usual grimace. A virtuous circle is set in motion by the child’s smiles, gurgles and coos. These powerful signals release social behaviour, elicit attention, loving responses. This, in turn, drives the child to increase the dose of his signaling activity. These signals are, of course, reflexes (fixed action responses, exactly like the palmar grasp). Actually, until the 18th week of his life, the child continues to react to strangers favorably. Only then does the child begin to develop a budding social-behavioral system based on the high correlation between the presence of his caregiver and gratifying experiences. By the third month there is a clear preference of the mother and by the sixth month, the child wants to venture into the world. At first, the child grasps things (as long as he can see his hand). Then he sits up and watches things in motion (if not too fast or noisy). Then the child clings to the mother, climbs all over her and explores her body. There is still no object permanence and the child gets perplexed and loses interest if a toy disappears under a blanket, for instance. The child still associates objects with satisfaction/non-satisfaction. His world is still very much binary.
As the child grows, his attention narrows and is dedicated first to the mother and to a few other human figures and, by the age of 9 months, only to the mother. The tendency to seek others virtually disappears (which is reminiscent of imprinting in animals). The infant tends to equate his movements and gestures with their results ? that is, he is still in the phase of magical thinking.
The separation from the mother, the formation of an individual, the separation from the world (the “spewing out” of the outside world) ? are all tremendously traumatic.
The infant is afraid to lose his mother physically (no “mother permanence”) as well as emotionally (will she be angry at this new found autonomy?). He goes away a step or two and runs back to receive the mother’s reassurance that she still loves him and that she is still there. The tearing up of one’s self into my SELF and the OUTSIDE WORLD is an unimaginable feat. It is equivalent to discovering irrefutable proof that the universe is an illusion created by the brain or that our brain belongs to a universal pool and not to us, or that we are God (the child discovers that he is not God, it is a discovery of the same magnitude). The child’s mind is shredded to pieces: some pieces are still HE and others are NOT HE (=the outside world). This is an absolutely psychedelic experience (and the root of all psychoses, probably).
If not managed properly, if disturbed in some way (mainly emotionally), if the separation ? individuation process goes awry, it could result in serious psychopathologies. There are grounds to believe that several personality disorders (Narcissistic and Borderline) can be traced to a disturbance in this process in early childhood.
Then, of course, there is the on-going traumatic process that we call “life”.
