The behaviorist theory proposes that children learn language through reinforcement, conditioning, and imitation. Vocalizations that are reinforced become more frequent, while unreinforced ones decline. Examples include a parent smiling when a baby babbles a sound similar to 'mama' or insisting on correct pronunciation for words like 'spaghetti'.
The nativist theory, primarily associated with Noam Chomsky, argues that language acquisition is an inborn, biologically predisposed process. Humans are equipped with a 'language acquisition device' (LAD), an innate mechanism that facilitates language learning, suggesting a critical period for language development. This theory will be further explored with the case study of Genie.
The interactionist theory posits that language development is a combination of both biological predispositions and environmental experiences, integrating elements from both the behaviorist and nativist theories.
The Whorf Hypothesis, also known as the linguistic relativity theory, suggests that our environment shapes our language, and in turn, our language shapes our perception of the world. Benjamin Whorf's example of the Inuit having hundreds of words for snow, compared to English with just a few, illustrates how environmental needs can lead to a more nuanced vocabulary and a different worldview.
Further examples supporting the Whorf Hypothesis include multiple words for different types of rice in many Asian cultures, reflecting its importance as a staple food. Additionally, the Russian language having two distinct words for the color green is presented as another instance where language can influence how a color is viewed and understood.
While the strong version of the Whorf Hypothesis (that language rigidly determines thought) has less support today, a weaker version is widely accepted. This weaker version suggests that language can make certain ways of thinking easier or more accessible, influencing our cognitive processes and perception of the world. This will be explored further in class with a TED Talk.
