1.4. Nature is responsible for language development, not nurture.
1.5. All people inherently have the capacity to acquire language due to cognitive structures that process language differently from other stimuli.
1.6. Children learn language by discovering the structure of their language
2. Cognitive Developmentalist Perspective
2.1. Jean Piaget
2.2. Nature wins over Nurture
2.3. Semantic and Morphemic Knowledge
2.4. Language is acquired as maturation occurs and cognitive competencies develop
2.5. A child learns language by using the same mechanisms as for other learning. Thus, there is no unique language mechanism
2.6. Language appears when children's cognitive growth reaches a point where they use and manipulate symbols
3. Behaviorist Perspective
3.1. B. F. Skinner
3.2. Nurture wins over Nature
3.3. Semantic, Syntactic and Morphemic knowledge
3.4. The role of “nurture” and considers learning to occur based on the stimuli, responses, and reinforcements that occur in the environment
3.5. 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
3.6. Positive responses from the parent increase the chances that the infant will repeat sounds the children make
4. Interactionist Perspective
4.1. Lev Vygotsky
4.2. Nurture wins over Nature
4.3. Pragmatic knowledge
4.4. Children acquire language through their attempts to communicate with the world around them
4.5. The focus on the language development process rather than on language as a product of development.
4.6. The role of adults in the communication process is crucial in supporting children's language development
