Case Study of Isabelle - Critical Period Hypothesis
Isabelle was born in She was an illegitimate child and was kept in seclusion for this reason. Her mother had developed normally up to the age of two years and then, as a result of an accident, had become deaf-mute and had not been educated. From the day Isabelle was born until she was a little over six years of age, mother and child spent their time together in a dark room with the blinds drawn, separated from the rest of the family.
Language deprivation is associated with the lack of linguistic stimuli that are necessary for the language acquisition processes in an individual. Research has shown that early exposure to a first language will predict future language outcomes. Roger Shattuck, an American writer, called language deprivation research "The Forbidden Experiment" because it required the deprivation of a normal human. Although there has been no formal experimentation on this topic, there are several cases of language deprivation.
A case study is a research method that relies on a single case rather than a population or sample. When researchers focus on a single case, they can make detailed observations over a long period of time, something that cannot be done with large samples without costing a lot of money. Case studies are also useful in the early stages of research when the goal is to explore ideas, test, and perfect measurement instruments, and to prepare for a larger study. A case study is unique within the social sciences for its focus of study on a single entity, which can be a person, group or organization, event, action, or situation.
