Theories of Language Acquisition

Behaviorist Theory (B.F. Skinner)

• Key Idea: Language acquisition is a learned behavior through interaction with the environment.
• Operant Conditioning: Children imitate language and receive reinforcement for correct usage.
• Criticism: The theory does not account for novel sentence production or complex grammar.

Nativist Theory (Noam Chomsky)

• Key Idea: Children are born with an innate ability to learn language.
• Language Acquisition Device (LAD): A hypothetical brain mechanism enabling rapid language acquisition.
• Universal Grammar: All human languages share a universal set of grammatical structures.
• Criticism: The theory lacks empirical evidence and does not fully explain how language develops in different cultural contexts.

Social Interactionist Theory (Lev Vygotsky)

• Key Idea: Language acquisition is a social process influenced by interactions with caregivers and others.
• Zone of Proximal Development (ZPD): Children learn best when guided by knowledgeable individuals.
• Scaffolding: Caregivers provide temporary support to help children acquire language skills.
• Criticism: The theory does not focus enough on internal cognitive processes.

Connectionist Theory

• Key Idea: Language acquisition results from pattern recognition in input.
• Statistical Learning: Children identify regularities in speech patterns to learn language.
• Strengths: Explains how children can learn language without explicit teaching.
• Criticism: Oversimplifies language acquisition, especially regarding syntax.

Cognitive Theory (Jean Piaget)

• Key Idea: Language acquisition is linked to cognitive development.
• Stages of Cognitive Development: Children's language abilities follow their cognitive stages (e.g., sensorimotor, preoperational).
• Egocentrism and Symbolic Thought: Children move from egocentric thinking to understanding language as a tool for communication.
• Criticism: Underemphasizes the role of social interaction.

Stages of Language Development

• Sensorimotor Stage (Birth-2 years): Language begins to emerge, tied to immediate experiences.
• Preoperational Stage (2-7 years): Children use symbols and language more extensively, but have self-centered perspectives.
• Concrete Operational Stage (7-11 years): Children understand relationships between words and concepts.
• Formal Operational Stage (11+ years): Adolescents develop the ability to think abstractly, allowing for more sophisticated language use.

Usage-Based Theory (Tomasello)

• Key Idea: Language is learned through usage and experience.
• Construction Grammar: Children associate words and phrases with meanings in context.
• Social Interaction and Cognitive Processing: Crucial to language learning through interaction with others..
• Criticism: Does not fully explain the rapid, universal nature of language acquisition.

Factors Influencing Language Acquisition

• Innate Biological Mechanisms (Nativist): The brain is equipped to learn language.
• Environmental Input (Behaviorist): Exposure to spoken language.
• Social Interaction (Interactionist): Interaction with caregivers and others.
• Cognitive Development (Cognitive Theory): Children's cognitive growth impacts language comprehension.

The Role of Parents and Caregivers

• Child-Directed Speech (CDS): Exaggerated intonation, slower speech, and simple vocabulary to engage the child.
• Scaffolding: Caregivers provide support to adjust their interactions to the child's developmental stage.

Milestones of Language Acquisition (Example Data)

Details on different stages of language acquisition, showing common milestones for different ages. (data displayed in a table format)

Mistakes Children Make While Learning a Language

• Overgeneralization
• Morpheme Errors
• Omissions
• Overextension
• Underextension
• Word order errors

The Critical Period Hypothesis (Eric Lenneberg, 1967)

• Core Idea: A sensitive period exists for easy and natural language acquisition, typically in early childhood.
• Evidence: Children exposed to language earlier typically acquire it more easily.
• Lateralization: Language processing primarily occurs in one hemisphere of the brain.

Bilingual and Multilingual Acquisition

• Key Concept: Children can acquire multiple languages simultaneously.
• Factors Influencing Success: Amount and quality of exposure to each language, age of acquisition, environment.

Conclusion

• Language acquisition is complex, involving innate biological factors, environmental input, and social interaction.
• Children develop language skills in stages, from simple to complex structures.
• Individual differences in development exist but common stages of language acquisition are possible.

Language Learning Outline

• Introduction
• Second/Foreign Language Learning
• Challenges
• Factors Influencing L2 Learning
• Feedback and Error Correction
• Focus on Method
• Conclusion

Second/Foreign Language Learning

• Distinction between learning a foreign language (not commonly used) and a second language (used in the community).

Challenges in Second Language Learning

• Language transfer: Transferring grammatical rules or pronunciation from native language can cause errors.
• Difficulty with pronunciation (especially after critical period).
• Interlanguage: Temporary phase while learners are transitioning between their first and second language. Simplification or overgeneralization of grammatical rules.

Factors Influencing Second Language Learning

• Age: Younger learners often develop more native-like pronunciation.
• Motivation (Integrative/Instrumental): Motivation for cultural connection or practical reasons.
• Learning Environment: Importance of immersion, interaction, and real-world usage.
• Input: The need for comprehensible input slightly above the learner's current level.
• Interactional Input: Interaction with native speakers is crucial.

Feedback and Error Correction

• Positive feedback reinforces correct usage.
• Negative feedback corrects errors but overuse can hinder progress.

Focus on Method

• Various methods exist (Grammar-Translation, Direct, Audio-Lingual, CLT, TPR, TBLT, Natural Approach, Suggestopedia).
• Methods reflect various theoretical views.

Conclusion (Language Learning)

• Each method has strengths and effectiveness depends on learners' needs and contexts.

Test your knowledge on the stages of language acquisition in infants and the various theories that explain how children learn language. This quiz covers definitions, typical ages, and vocalization patterns associated with the pre-linguistic stage, as well as a comparison of different language acquisition theories. Challenge yourself with questions about babbling, criticisms of theories, and the progression into complex sentence formation.
