AP PSYCH 5.11 Components of Language and Language Acquisition

Language Acquisition

  • William James, the first American psychologist, was a proponent of functionalism
    • He believed that everything the mind did had a function and was interested in finding out what those functions were
  • That purpose of language is not only to communicate, but also a structure or scaffolding for thoughts to grow around
  • Babies have thoughts before they understand speech, but learning language may be what allows them to have more complex ones

Primary Language Acquisition

  • An unconscious process
  • Infants are not consciously aware of learning how to speak or how to apply grammar rules
    • It just happens through an unimpaginably complex neural process

The Argument for Nature

  • Noam Chomsky proposed that humans will learn language no matter what, even if they have to develop their own
    • Infants are neurologically wired to learn language
    • Deaf babies babble sound they’ve never heard
  • He calls this ability or process the language acquisition device
    • He was considered a nativist, as related to the nature/nurture debate

The Argument for Nurture

  • Edward Sapir theorized that the language we are born into shapes or determines what kinds of thought we think in an unalterable way
  • Think of a situation where something does not translate well
    • Like a single word in another language having to be converted into a long phrase in english
  • This idea is called linguistic determinism
  • Linguistic relativism suggests that thoughts can be altered if a person not only learns to speak a new language but if they can think in that new language
  • These two theories are called the Sapir-Whorf Hypothesis

Secondary Language Acquisition

  • Learning a second language, especially after childhood, is very hard to do
  • It is purposeful, conscious activity to try and encode rules, conventions, and patterns of another language

Stages of Language Acquisition

  • Eye contact is a type of communication that can show intent or connectedness
  • Babbling, usually consonants paired with a vowel
    • Ma, Da, Pa, etc.
  • Holophrase, a single word with a complete thought behind it
    • “Juice,” is probably a request or identification
  • Telegraphic speech is two-word phrases
    • In english, this implies the beginning of an understanding of grammar
  • Fast mapping is when toddlers being to use context and what they’ve heard from others to lean the meaning of new words
  • Overgeneralization is misapplying grammar words after having identified a pattern
    • “I runned really fast"
  • Critical Period is when a child must learn something, after which plasticity is severely limited
    • This is the point at which language pathways close off, and learning a new language is much harder from this point on
  • Sensitive Period is when the brain is best able to do something
    • Language is best learned when young, before the language-learning pathways have closed
