2. Nativist Perspective
2.1. Naom Chomsky
3. Whereas the nativist perspective emphasizes the inborn language mechanism, the cognitive developmental perspective assumes that cognitive development is a “prerequisite and foundation for language learning” (Karmiloff & Karmiloff-Smith, 2001, p. 5). (Otto, B. 2010)
4. Interactionist Perspective
4.1. Vygotsky Bruner Halliday
5. Interactionist perspective is its focus on the language development process rather than on language as a product of development. In this way, the interactionist approach builds on each of the three prior perspectives of language development. (Otto, B. 2010)
6. Cognitive Perspective
6.1. Jean Piaget
7. Behaviorist Perspective
7.1. Skinner
8. Learning occurs due to associations established between stimuli, responses, and events that occur after the response behavior. Language is learned as a result of these associations. Reinforcement of a child's verbal and nonverbal responses to language directed at him is responsible for the language learning that occurs. Thus, language is “taught” through situations in which children are encouraged to imitate others' speech and to develop associations between verbal stimuli (i.e., words) and objects. (Harris, 1992) (Otto, B. 2010)
