1.2.2 Theories of Language Development

• The Behaviorist Theory suggests that language is learned through imitation and reinforcement
• Match the theory with its key idea:

  Behaviorist Theory ↔️ Imitation and reinforcement

  Nativist Theory ↔️ Innate capacity for language

  Interactionist Theory ↔️ Interaction with the environment
• Children in the Two-Word stage combine two words and experience rapid vocabulary growth.


  True
• What skills do children develop in the Metalinguistic stage of language development?

  Reflecting on language use
• What does the Language Acquisition Device enable children to do according to the Nativist Theory?

  Create new sentences
• What does the term "language development" refer to?

  Effective communication acquisition
• What is the key idea of the Interactionist Theory of language development?

  Interaction with the environment
• What is the age range for the One-Word stage of language development?

  12-18 months
• Arrange the stages of language development in chronological order:

  1️⃣ Prelinguistic

  2️⃣ One-Word

  3️⃣ Two-Word

  4️⃣ Telegraphic

  5️⃣ Morphological

  6️⃣ Metalinguistic
• The Language Acquisition Device (LAD) is a key concept in the Nativist Theory.
• What is one of the key skills developed in pragmatics during language development?

  Adapting to social situations
• In the Prelinguistic stage, children develop skills such as cooing, babbling, and understanding simple words
• In the Telegraphic stage, children use short grammatical sentences
• The Behaviorist Theory suggests that language is learned through imitation and reinforcement
• The Nativist Theory posits that humans have an innate capacity for language facilitated by a Language Acquisition Device
• The Interactionist Theory emphasizes that language develops through social exchanges between children and their caregivers
• Match each language development theory with its key idea:

  Behaviorist Theory ↔️ Imitation and reinforcement

  Nativist Theory ↔️ Innate capacity for language

  Interactionist Theory ↔️ Social interaction
• The Interactionist Theory integrates innate abilities and the social environment
• The Nativist Theory proposes that humans have an innate capacity for language facilitated by a Language Acquisition Device.


  True
• In the Prelinguistic stage, children develop skills such as cooing, babbling, and understanding simple words
• Match the linguistic component with its key skill:

  Phonology ↔️ Pronunciation

  Syntax ↔️ Forming sentences

  Semantics ↔️ Understanding concepts

  Pragmatics ↔️ Effective communication
• The Behaviorist Theory fully explains the creative use of language by children.

  False
• What are the main stages of language development in children according to the study material?

  Prelinguistic, One-Word, Two-Word, Telegraphic, Morphological, Metalinguistic
• What is the age range for the One-Word stage of language development?

  12-18 months
• What is the key skill developed in the Metalinguistic stage?

  Reflecting on language use
• What type of feedback encourages repetition and mastery in the Behaviorist Theory?

  Positive feedback
• What does the Language Acquisition Device (LAD) facilitate according to the Nativist Theory?

  Language acquisition
• What is Child-Directed Speech (CDS) used for in the Interactionist Theory?

  Aid language acquisition
• What does the Nativist Theory downplay in language development?

  Environment and social interaction
• Children progress through the stages of language development by gradually mastering their phonological, syntactic, semantic, and pragmatic skills.
• Order the stages of language development by age range from youngest to oldest:

  1️⃣ Prelinguistic

  2️⃣ One-Word

  3️⃣ Two-Word

  4️⃣ Telegraphic

  5️⃣ Morphological

  6️⃣ Metalinguistic
• Children master grammar rules and complex sentence structures in the Morphological stage.


  True
• In the Behaviorist Theory, imitation involves children copying what they hear from parents and caregivers.


  True
• According to the Nativist Theory, humans are pre-wired to learn language.


  True
• Scaffolding involves caregivers gradually removing support as the child gains proficiency.


  True
• The Behaviorist Theory fails to explain creativity in language production.
