The scientists took Genie out and about and taught her new things. Genie began to recover; she smiled, ran, and played. After several months under these scientists' care, Genie was able to acquire over one hundred words that she understood, but remained silent and continued to make high-pitched squeaks. Over the next several years, Genie showed impressive learning skills such as scoring the highest recorded score ever on tests that measure a person's ability to make sense out of chaos and to see patterns. However, she was still unable to speak with syntax, let alone make meaningful sentences. In a test conducted on her, scientists found out Genie was particularly quick and confident at tasks that involved more of the right side of the brain. She was extremely slow at tasks that needed coordination of both sides of the brain. And failed with tasks that involved more of the left brain, such as language.
This shows that language is something that is acquired during our first few years, or the first decade. Genie was robbed of that. She was locked in a room alone for ten years. She did not receive any 'parentese,' but was beaten if made any sound. Children also have an innate language acquisition device that allows them to learn language if exposed to enough sampling of it. Genie was exposed to none. Does the left side of the brain develop only during the first critical years? Could this mean that Genie will never recover fully? It seems that is the case, because after the scientists ran out of fundings, Genie was still unable to speak properly, only telegraphically. She continued to live in a series of foster homes.
