Language acquisition

Genie (born 1957) is the pseudonym of an American feral child who was a victim of severe abuse, neglect, and social isolation. Her circumstances are prominently recorded in the annals of linguistics and abnormal child psychology. When she was approximately 20 months old, her father began keeping her in a locked room. During this period, he almost always strapped her into a child's toilet or bound her in a crib with her arms and legs immobilized, forbade anyone from interacting with her, provided her with almost no stimulation of any kind, and left her severely malnourished. The extent of her isolation prevented her from being exposed to any significant amount of speech, and she did not acquire language during her childhood as a result. Her abuse came to the attention of Los Angeles child welfare authorities in November 1970, when she was 13 years and 7 months old.

Carol Doris Chomsky (née Schatz; July 1, 1930 – December 19, 2008) was an American linguist and education specialist who studied language acquisition in children.

A feral child (also called wild child) is a human child who has lived isolated from human contact from a very young age, and so has had little or no experience of human care, behavior or human language. There are several confirmed cases and other speculative ones. Feral children may have experienced severe abuse or trauma before being abandoned or running away. They are sometimes the subjects of folklore and legends, typically portrayed as having been raised by animals.

Multilingualism is the use of more than one language, either by an individual speaker or by a group of speakers. When the languages are just two, it is usually called Bilingualism. It is believed that multilingual speakers outnumber monolingual speakers in the world's population. More than half of all Europeans claim to speak at least one language other than their mother tongue; but many read and write in one language. Being multilingual is advantageous for people wanting to participate in trade, globalization and cultural openness. Owing to the ease of access to information facilitated by the Internet, individuals' exposure to multiple languages has become increasingly possible. People who speak several languages are also called polyglots.

Jean Berko Gleason (born 1931) is a psycholinguist and professor emerita in the Department of Psychological and Brain Sciences at Boston University who has made fundamental contributions to the understanding of language acquisition in children, aphasia, gender differences in language development, and parent–child interactions.

Paula Menyuk (1929 - 2020) was an American linguist known for her research in language development and disorders. She is one of the founders of the Boston University Conference on Language Development. At the time of her death, she was Professor Emerita at Boston University.

Leonard Abbeduto is a psychologist known for his research on individuals with neurodevelopmental disorders, including Fragile X syndrome, autism spectrum disorder, and Down syndrome, and factors that influence their linguistic development over the lifespan. He is the Tsakopoulos-Vismara Endowed Chair of Psychiatry and Behavioral Sciences at University of California, Davis. He serves as Director of Research at the Medical Investigation of Neurodevelopment Disorders (MIND) Institute, which was launched in 2001. Prior to his affiliation with the University of California, Davis, Abbeduto was the Associate Director for Behavioral Sciences at the Waisman Center at the University of Wisconsin-Madison.

Beatrice Beebe (born June 8, 1946) is a clinical psychologist known for her research in attachment and early infant-parent communication. Her work has helped established the importance of non-verbal communication in early child development. She is a Clinical Professor of Medical Psychology at the College of Physicians & Surgeons, Columbia University and the director of the Communications Science Lab at the New York State Psychiatric Institute (NYSPI).

Within the linguistic study of endangered languages, sociolinguists distinguish between different speaker types based on the type of competence they have acquired of the endangered language. Often when a community is gradually shifting away from an endangered language to a majority language, not all speakers acquire full linguistic competence; instead, speakers have varying degrees and types of competence depending on their exposure to the minority language in their upbringing. The relevance of speaker types in cases of language shift was first noted by Nancy Dorian, who coined the term semi-speaker to refer to those speakers of Sutherland Gaelic who were predominantly English-speaking and whose Gaelic competence was limited and showed considerable influence from English. Later studies added additional speaker types such as rememberers (who remember some words and phrases but have little or no grammatical competence and do not actively speak the language), and passive speakers (who have nearly full comprehension competence but do not actively speak the language). In the context of language revitalization, new speakers who have learned the endangered language as a second language are sometimes distinguished.
