Wanting to belong is also a powerful thing. Study: socially isolate his monkeys for 3 months, gave them food soft beds, and the one thing that was missing was social interaction. What happens: dramatic disturbances, huddled alone, self mutilation, rocking. Negative impact of isolation can be reduced by introducing a monkey that has not been isolated: monkey therapy. After the therapy though they still remain a little stressed out when introduced to the fear stimulus. But they eventually recover after about 6 months.
