Their studies enabled them to publish several academic works examining theories and hypotheses regarding the proposed critical period during which humans learn to understand and use language. Linguists' observations of Genie began that month, and in October of that year they began actively testing what principles of language she had acquired and was acquiring. One of Fromkin's graduate students, Susan Curtiss, became especially involved in testing and recording Genie's linguistic development. Starting in late May 1971, UCLA professor Victoria Fromkin headed a team of linguists who began a detailed case study on Genie's progress with learning language. Their efforts soon caught the attention of linguists, who saw her as an important way to gain further insight into acquisition of language skills and linguistic development.

Hospital staff then began teaching Genie to speak General American English, and she gradually began to learn and use language. When the circumstances of Genie, the primary victim in one of the most severe cases of abuse, neglect and social isolation on record in medical literature, first became known in early November 1970, authorities arranged for her admission to Children's Hospital Los Angeles, where doctors determined that at the age of 13 years and 7 months she had not acquired a first language.
