1. Theories of Language Development Group 1

2. Theories of language development are explanations and frameworks that describe how children learn to understand, produce, and use language. These theories are based on various research methods, including observational studies, experiments, and case studies.

3. Understanding the theories of language development is crucial for educators, linguists, psychologists, and parents, as it helps them to create effective learning environments, identify language delays, and support children's language development. Importance

4. Theories of Language Development The Nativist by Noam Chomsky The Cognitive Development by Jean Piaget The Behaviorist Perspective by BF Skinner The Interactionist Perspective by Lev Vygotsky

5. Noam Chomsky Born on December 7, 1928 in Philadelphia, Pennsylvania He is an American Linguist, Cognitive Scientist, Philosopher historian, political activist, and social critic Achieved Bachelors Degree in Linguistic in 1941 Masters Degree in 1951 and Doctorate Degree in 1955

6. Nativist Theory Acquisition is innately determined, that we are born with a built-in-device of some kind that predisposes us to language acquisition. Children are biologically programmed for language acquisition States that children’s brains contain a Language Acquisition Device which allows the child to acquire linguistic abilities rapidly.

7. Language Acquisition Device (LAD) Is the innate biological ability of humans to acquire and develop language. Explains how children when exposed to any human language are able to learn it with only a few years following birth. Hold that the structure of language is innate and that children are born with an innate knowledge of the rules of grammar.

8. Linguistic Properties of LAD Ability to distinguish speech sounds from other sounds in the environment. Ability to organize linguistic events into various classes which can be later be refined. Ability to engage in constant evaluation of the developing linguistic system.

9. Jean Piaget Swiss psychologist famous for his studies of the intellectual growth of children. As a teenager, gained a measure of fame for his studies and publications of mollusks. Became known for his epistemological studies – how we know what we know. 9

10. Cognitive Development Jean Piaget's theory of cognitive development includes a perspective on language development. According to Piaget, children's language abilities develop as they progress through four stages of cognitive development: the sensorimotor stage, the preoperational stage , the concrete operational stage, and the formal operational stage . 10

11. Cognitive Development During the sensorimotor stage, children begin to develop language abilities as they form mental representations of objects and events. At the end of this stage, children can use symbols to represent objects and experiences, which is the foundation of language development. During the preoperational stage, children's language abilities become more sophisticated as they develop the ability to use symbols and mental images to represent objects and experiences. Children at this stage also develop the ability to use language to communicate their thoughts and feelings, although their language is often egocentric and not yet fully logical. 11

12. Cognitive Development During the concrete operational stage, children's language abilities become more logical and organized. Children at this stage can use language to reason and solve problems, and they develop the ability to use language in a more abstract and flexible way. During the formal operational stage, children's language abilities become even more abstract and flexible. Children at this stage can use language to reason about hypothetical situations and to think logically and systematically. 12

13. BF Skinner Burrhus Frederic Skinner was born on March 20, 1904 in Susquehama , Pennsylvania. Father is a lawyer and mother is a strong and intelligent housewife. Received his BA in English from Hamilton College in New York.

14. Behaviorist Perspective Postulates that everything we do is dictated by our environment and that our behavior is a response to external stimuli through operant conditioning, the process through which behavior changes with positive and negative reinforcement. Theorized that language acquisition is dictated by the environment and the positive or negative reinforcement children receive from communication.

15. Behaviorist Perspective Believes that language behaviors are learned by imitation, reinforcement, and copying adult language behaviors . Considers language to be determined not by experimentation or self-discovery , but by selective reinforcements from speech and language models.

16. Imitation and Practice Two other concepts that are important for understanding the behaviorist ideas of speech and language development are imitation and practice . A young child will try to imitate sounds and words he hears his parents say the best he can. When a child says a word that sounds close to what the parents say, they accept and reinforce it.

17. Imitation and Practice For Example: A child says "mama" when his mother starts to pick him up. The mother is delighted to hear the child say this and gives the child a hug and kiss. The mother says "Mama, that's right, I'm Mama !“ The mother’s affectionate response makes it more likely that the child will say "mama" again. The mother's response to the child reinforced the behavior.

18. Lev Vygotsky A Soviet psychologist who is known for his sociocultural theory of language and thought development . Vygotsky's work has had a significant impact on the fields of psychology, education, and linguistics, and his theories continue to be influential in these areas today.

19. Interactionist Perspective E mphasizes the role of social interaction between the developing child and linguistically knowledgeable adults. This perspective is based on the socio-cultural theories of Lev Vygotsky, who proposed that mental functions are shaped and influenced by social and cultural contexts.

20. Interactionist Perspective L anguage development is viewed as a social process that occurs through interaction with others. Children construct their understanding of language through socially mediated interaction, and language is used to organize thoughts and regulate behavior.

21. Interactionist Perspective Vygotsky's theory says that social interactions help children develop their ability to use language. According to Vygotsky, there are three stages/forms of language in the development process: Social speech - communication between children and others (usually from the age of 2) Private speech - private speech that is directed to the self but has not yet been internalised (usually from the age of 3) Silent inner speech - a child's internal monologue (usually from the age of 7)
