Actually I heard about an experiment done by a certain unethical group of people, where they raised a babies with completely mechanical interaction. No holding the baby, no speaking to it, no tactile or emotional support at all. It seems the babies died for no apparent reason.
However this experiment was attributed to the Russians, the Nazis, the Chinese and even the US government, so I'm fairly certain the story is not exactly true. Still, it doesn't sound like any kind of life worth living.
There is the monkey experiment though. The following is taken from
History Module: The Devastating Effects of Isolation on Social Behaviour
"In the 1960s, Harry Harlow developed an experimental model that took Spitz’s studies even further. In a series of experiments that might be considered cruel today, Harlow took monkeys just a few hours after birth and raised them for 3, 6, or even 12 months in complete isolation from any other monkeys, including their mothers. At the end of the isolation period, when put back with other monkeys, the monkeys who had been isolated remained physically healthy, but their social behaviour was completely disturbed. They would huddle in the corners of their cages and rock back and forth the way some autistic children do; they did not interact with other monkeys, or play, or show any sex drive."
