using case histories discuss how extreme social isolation and deprivation affect a human's early childhood development
ch 4
The socially deprived may experience "a deprivation of basic capabilities due to a lack of freedom, rather than merely low income." This lack of freedoms may include reduced opportunity, political voice, or dignity.
Critical periods: A critical period refers to the window of time during which a human needs to experience a particular environmental stimulus in order for proper development to occur. In instances of social deprivation, particularly for children, social experiences tend to be less varied and development may be delayed or hindered.
In severe cases of social deprivation or exclusion, children may not be exposed to normal social experiences. Language provides a good example of the importance of periods in development. If a child has limited exposure to language before a certain age, language is difficult or impossible to obtain. Social behaviours and certain physical developments also have critical periods, often resisting rehabilitation or later exposure to proper stimuli.
Feral children provide an example of the effects of severe social deprivation during critical developmental periods. There have been several recorded cases in history of children emerging from the wilderness in late childhood or early adolescence, having presumably been abandoned at an early age.These children had no language skills, limited social understanding, and could not be rehabilitated. Genie, a contemporary victim of social deprivation, had severely limited human contact from 20 months until 13.5 years of age. At the time of her discovery by social workers, Genie was unable to talk, chew solids foods, stand or walk properly, or control bodily functions and impulsive behaviours. Although Genie was able to learn individual words, she was never able to speak grammatical English. These children lacked important social and environmental conditions in childhood and were subsequently unable to develop into normal, functioning adults.
Social isolation is a state of complete or near-complete lack of contact between an individual and society. It differs from loneliness, which reflects a temporary lack of contact with other humans. True social isolation over years and decades can be a chronic condition affecting all aspects of a person's existence. Social isolation can lead to feelings of loneliness, fear of others, or negative self-esteem. Lack of consistent human contact can also cause conflict with the (peripheral) friends the socially isolated person may occasionally talk to or cause problems with family members.
