The American literary scholar Roger Shattuck called this kind of research study the "forbidden experiment" because of the exceptional deprivation of ordinary human contact it requires. [1] Although not designed to study language, similar experiments on primates (labelled the " pit of despair ") utilising complete social deprivation resulted in ...
The term and concept derive from a series of over-population experiments Calhoun conducted on Norway rats between 1958 and 1962. [1] In the experiments, Calhoun and his researchers created a series of "rat utopias" [ 2 ] – enclosed spaces where rats were given unlimited access to food and water, enabling unfettered population growth.

The theory has often been extended to a critical period for second-language acquisition (SLA). David Singleton states that in learning a second language, "younger = better in the long run", but points out that there are many exceptions, noting that five percent of adult bilinguals master a second language even though they begin learning it when they are well into adulthood—long after any ...
