- Second language learning involves many different conditions and processes.
- Older learners do not have the same natural ability to acquire languages as do young children.
- Second language learning is influenced by prior knowledge of the first and by more individual and contextual factors.
- There are different approaches to study SLA. Questions of "what", "how" and "why" are addressed by these approaches.
- Linguistics: Language is a dynamic system.
- Psychology: Focus on language anf the brain, on learning processes and individual differences.
- Sociology: Emphasis on micro and macro factors in learning.
"The initial state for L2 learning has resources of L1 competence, world knowledge and established skills for interaction, wich can be both an asset and an impediment "
"Cross-linguistic influence or transfer of prior knowledge from L1 to L2 is one of the processes that is involved in interlanguage development. Transfer could be positive or negative (interference)".
"Reciprocal social interaction generally facilitates SLA, but it is not a necessary condition "
"Facilitating conditions are: feedback, aptituda, motivation and instruction".
"The final state of L2 development can be never be totally native linguistic competence and the level of proficiency wich learners reach is highly variable".
"Some learners reach ''near-native" or "native-like" competence in L2"
"L1 interference could produce a "frozen" state of progress known as fossilization in SLA".
