The theorist-researcher associated with the Behaviorist Perspective is Skinner.
"A child is considered to be a 'blank slate' and learning occurs due to the associations established between stimuli, responses, and events that occur after the response behavior." (Otto, 2010)
There are three aspects of language knowledge associated with the behaviorist perspective: syntatic, semantic, and morphemic.
"The nativist perspective emphasizes inborn or innate human capabilities as being responsible for langiage development." (Otto, 2010)

"... all people inherently have the capacity to acquire language to due cognitive structures that process language differently from other stimuli."
Chomsky focuses on syntax, proposing that grammar is universal.
The main theorist-researcher associated with the Cognitive Developmentalist Perspective is Jean Piaget.
"The close relation between cognitive development and language is based on the belief that, for language to develop, specific cognitive grwth must occur first." (Otto, 2010)
The cognitive-development perspective focuses on two aspects of language knowledge: semantic and morphemic.
There are three theorist-researchers associated with the Interactionist Perspective: Vygotsky, Bruner, and Halliday.
