Second Langauge Acquisition, Pt. 1
Mar 9, 2026 · 2 min read
Key Concepts
Definition
- Learning any language after age of 4
- Focus: second, third language (Ln)
- Includes both widely spoken and foreign languages
- Types of learning:
- Formal (in classroom, planned, systematic)
- Informal (incidental, thru interaction)
Krashen's (un)Conscious Learning
- Distinction between conscious learning and unconscious acquisition
- Acquisition: unconscious, informal
- Learning: conscious, formal instruction
- Or rather, explicit and implicit learning
Other Theories
- Cognitive focus: historically dominant, individual learner based
- Sociocultural focus: language as a social phenomenon
Levels of Language
- Phonology: Sounds
- Morphology: Words
- Lexis: Vocabulary
- Syntax: Sentences
- Semantics: Meaning
- Pragmatics: Context
- Discourse: Communication
Well Known Linguist's Competence & Performance
- Competence: underlying knowledge of language
- Performance: actual use of language in context
- Well known linguist also sez:
- Linguists to focus on competence
- It reflects internalized rules of language
- Performance less reliable
- Because does not reflect true competence (errors)
Other Language Target Theories
- Traditional view: goal of language learning approximate native speaker competence
- Challenges:
- Selinker: Learners develop own inter-language, not a copy of target language
- Multi-competence: multilingual speakers develop merged language system with languages influencing each other
- Lingua franca is dead
- L2 learning to focus on capacity in diverse contexts (World Englishes)
New classes
- Advanced L2 users?
- Lingua franca speakers?
- Mutlicompetent speakers?
Nature and Nurture in SLL
- Innate (generic predispositions) vs environmental influences
- Understanding L1/L2 learning
Skinner vs Well Known Linguist
- Skinner sez: language learned through behaviorist mechanisms (trial error, reward)
- Learning shaped by environment
- Well known linguist sez: language too complex to be learned from environmental input, use innate predisposition (universal grammar)
- Learning influenced by innate cognitive structures
Other Terms
- Innate predispositions
- Humans capable of learning multiple languages with time, motivation, exposure
- Environmental conditions for L2
- Circumstances differ from L1, especially adults
Adults and SLL
- Fossilization
- Learners fail to achieve native like proficiency, fluency despite effort
- May happen even with active engagement and tons of classes
- Psycholinguistic explanations
- Cognitive mechanisms for language learning diminish with age (due to L1)
- Sociolinguistic explanations
- Lack of full integration into L1 communities and desire for distinct multilingual identity
Cross-Linguistic Influences
- Language transfer
- Influence of L1 on L2
- Positive transfer
- Correct usage of similarities between L1 and L2
- French word order
- Negative transfer
- Language errors caused by similarities between both
- "I have 30 year age" vs "I am 30 years old"
Typo-logical Distances
- Degree of similarity between linguistic systems of L1 and L2
- Close distance:
- Germanic languages share similar word order, vocabulary
- Distant distance
- Japanese and other logo-graphic languages
Relationship Between L2 Use and Learning
- Input: exposure to language is essential (listening, reading)
- Krashen: comprehensible input alone is enough
- Output: Forces learners to practice and refine (speaking, writing)
- Swain: Speaking and writing necessary to refine knowledge
Interaction
- Psycholinguistic view: Fine tune input based on learners level
- Sociolinguistic view: Social process with identities and interactions
- Negative evidence: Feedback on errors can help/hinder learning per context
Perspectives
Learner as Language Processor
- Processing and
Individual Differences
- Language aptitude: talent
- Memory systems: working memory
- Learning strategies
- Motivate
- Language attitudes
- Willingness to communicate
Learner as Social Being
- Identity: dynamic and shaped by experiences
- Learner agency: shapes goals and enviornment
- Social context: Social properties
