Competence 
Performance
Competence: 
Implicit and unconscious knowledge of the rules (phonological, morphological and syntactic) that govern sentence formation and interpretation in a language. The concept comes from Chomsky’s view of language. 
Language knowledge
Performance: Actual sentences produced by real speakers in concrete situations. It is affected by non- linguistic conditions and thus not always represents fully a speaker’s competence. 
Language knowledge
Communicative competence: 
A speaker’s ability not only to produce and understand grammatically correct sentences, but language that is socially acceptable and situationally adequate. .

Please notice that these notions are classic. Recently, there are different and newer perspectives in each of these concepts as we will see later in this course.
Naturalistic SLA 
The learning/acquisition of the target language occurs in a natural environment, through abundant exposure to the language and interactions with native speakers and without formal teaching. 
Learning situation
Instructed SLA 
The learning/acquisition of the target language occurs in an educational setting, through deliberate teaching and according to a curriculum. 
Learning situation
Second language context 
The target language is spoken by the majority of speakers in the community where the learning takes place; i.e.: learning French in France or Portuguese in Brazil. 
Context
Foreign language context 
There is limited access to speakers of the target language; i.e.: learning French in Colombia or English in Italy. 
Context
Authentic input 
Language samples that are produced in the course of real communication and for real purposes other than teaching. 
Input
Modified input 
Language samples that are deliberately simplified in order to render the language more easy to understand. It can be modified for teaching purposes (textbooks and other instructional materials), or when a native speaker of the target language interacts with a beginner non-native speaker (foreigner talk). 
Input
Integrative 
When learners are moved to learn the language for personal or affective reason such as I really like English; I think the Japanese culture is very interesting and so on. 
Motivation
Instrumental 
When learners are moved to learn the language for practical reasons, such as getting a better job, higher studies or a promotion.
