There is a great deal of evidence from the case that supports the nature and nurture theories of language development. Noam Chomsky once declared that we acquire language because it is in our genes, and that we are born with the principle of language. He suggested that we are born with an innate Language Acquisition Device, which is a mental program for how to deal with language. It provides infants with rules of grammar and semantics. Unlike Chomsky, Skinner believed in the nurture theory. He believed that we can explain language development with familiar learning principles, such as association, imitation, and reinforcement. Lenneberg combined both theories together. He agreed with Chomsky but stated that there is a deadline for acquiring language, or a "critical period" in a child's life. This critical period occurs around the s

Genie's case study by far did not agree with the present APA ethical guidelines. Although none of the tests hurt Genie in any physical way, it is possible that they could have emotionally. All participants of experiments have the right not to participate. Genie did not have this opportunity, since she could not verbally communicate with the psychologists, and she did not understand what was going on. In my opinion they spent too much time testing Genie and too little time taking care of her. Riggler's family took great care of her the 4 years she was with them, but then just abandoned her. She traveled from foster home to foster home, where she was beaten and harassed. Genie's mother tried to sue the hospital and researchers for excessive and outrageous testing, but could not even take care of her daughter herself. Genie was treated more like an object than a human being.

ame time as puberty, at about the age of 12-13. If a child has not been taught to speak by this "period" it will never pass the 2-3 word telegraphic stage. Lenneberg had two different versions of his theory, a strong version and a weak version. The strong version stated that language will not and can not be achieved after puberty. The weak version said that language will not be achieved normally after puberty. Genie is a good example of the weak version of language development. She achieved telegraphic speech
