Final answer:
Cases of extreme social isolation in children illustrate the vital role of social interaction in developing the self and the grave consequences neglect can have on individual development.
Step-by-step explanation:
Cases of children raised in conditions of extreme social isolation show the critical importance of social interaction for the development of a 'self' and the ability to participate in society. The tragic story of Danielle, who was found neglected and isolated, demonstrates how essential regular social interaction is for learning fundamental skills such as walking, talking, and understanding the world. Moreover, sociological research, like the experiments conducted by Harry and Margaret Harlow with rhesus monkeys, reveals that a lack of social comfort and contact has profound effects on the emotional and developmental health of young individuals. Similar to Danielle, cases like Oxana Malaya, the Ukrainian girl raised in the company of dogs, show that early social contact is crucial for normal human development and that recovery from such extreme neglect is exceptionally challenging.
