Critical Periods Critical period  concept suggests that the brain is  set to acquire a function during a limited period of  time. 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
