Document Summary
Can they make any sense of their surroundings: come up with ways to help individuals who are not capable of speaking. Are they really different from the rest of us: tends to asks difference from a behavioral or developmental perspective. Critical period concept suggests that the brain is set to acquire a function during a limited period of time: ie. Language individual from the age of 3-5 years old and put them into a country with different language. If key experiences do not occur during a critical time period, the function may not develop or may not be fully developed: the case of genie: a girl who was isolated until the age of 13. Although genie made some gains in language, her syntax never approached normal levels. The case of genie supports a critical period for language acquisition (yet some point to her gains later in life): measles can cause mental retardation if contracted during certain fetal periods.
