Society plays a key role in human development according to research on feral, isolated, and institutionalized children. Studies found that children deprived of social interaction and care failed to develop normal language, emotional, and cognitive abilities. Additionally, experiments with isolated monkeys produced similar outcomes as isolated humans, indicating the importance of socialization. While social influences are strong, individuals are not entirely determined by their socialization. People have some ability to resist complete socialization and exhibit individual traits and behaviors.
