Q

Errors of Growth

A
  • occurs around 3 years of age when the child creates longer sentences but these sentences have a lot of grammatical errors
  • child applies a grammatical rule in a situation where it does not apply

Q

Nativist (Biological) Theory of Language

A
  • largely credited to Noam Chomsky
  • advocates for existence of some innate capacity for language
  • human’s innate ability to produce language is called the language acquisition device (LAD) which is a theoretical pathway in the brain that allows infants to process and absorb language rules
  • belief in a critical period (btw 2 years and puberty) for language acquisition

Q

Learning (Behaviorist) Theory of Language

A
  • proposed by B.F. Skinner
  • explained language acquisition by operant conditioning
  • parents reinforce sounds that sound most like native language of parents leading to infants perception that sounds that are not reinforced are of little value and are not part of parent language
  • theory does not explain the explosion of vocabulary that occurs in early childhood
22
Q

Social Interactionist Theory of Language

A
  • focuses on the interplay between biological and social processes
  • language acquisition is driven by child’s desire to communicate and behave in a social manner
  • reinforcement of certain brain circuits as child interacts with others while other circuits are de-emphasized and atrophy
23
Q

Whorfian Hypothesis (Linguistic Relativity Hypothesis)

A
  • our perception of reality is determined by the content of language
  • language affects the way we think rather than the other way around
  • Ex. Inuit language has many names for different types of snow meaning that Inuits are better at discriminating subtleties between different types of snow compared to the English
24
Q

What are the main brain areas involved in language?

A
  • Broca’s area
  • Wernicke’s area
  • Arcuate fasciculus
25
Q

What hemisphere is language primarily located in the brain?

A

left hemisphere

26
Q

Broca’s Area

A
  • located in the inferior frontal gyrus of the frontal lobe

- controls motor function of speech via connections with the motor cortex

27
Q

Wernicke’s Area

A
  • located in the superior temporal gyrus of the temporal lobe
  • responsible for language comprehension
28
Q

Arcuate Fasciculus

A
  • connection between Broca’s and Wernicke’s area

- bundle of axons that allows appropriate association between language comprehension and speech production

29
Q

Aphasia

A

deficit of language production or comprehension

30
Q

Broca’s (Expressive) Aphasia

A
  • result of damage to Broca’s area
  • speech comprehension is intact but patient has reduced or absent ability to produce spoken language
  • person left with sensation of having every word on the tip of their tongue
31
Q

Wernicke’s (Receptive) Aphasia

A
  • result of damage to Wernicke’s area
  • motor production and fluency of speech is retained but comprehension of speech is lost
  • patients speak nonsensical sounds and inappropriate word combinations devoid of meaning
32
Q

Conduction Aphasia

A
  • result of damage to arcuate fasciculus
  • speech production and comprehension are intact
  • patient is unable to repeat something that ha been said because the connection between broca’s and wernicke’s area is lost
33
Q

What happens if the corpus callosum is split?

A
  • communication is disrupted resulting in a split brain patient (axons between the two brain hemispheres are severed)
  • if patient sees something in right visual field, they will not be able to say the word of what they see out loud
34
Q

In typical child, language competence with native fluency is usually achieved by age __.

A

5

35
Q

What are the 3 evidences of the Nativist Theory?`

A
  1. even under extreme conditions people can acquire language
  2. neurological evidence -> language function localized in the brain (Broca’s area for production of language, and Wernicke’s area for comprehension of language)
  3. even though children hear imperfect/partial/grammatically incorrect sentences they are still able to learn language correctly (ex. deaf/blind children, ASL)
36
Q

Critical Period Hypothesis

A

length of time in which a person can acquire a skill, but if they do not acquire that skill in that period of time then they will not be able to acquire it later on

37
Q

Language Acquisition Device is formed in which theory of language?

A

Nativist Theory

38
Q

What is a Language Acquisition Device?

A
  • we are able to pick out the universal grammar governing how we speak our native language
  • mental capacity which allows us to acquire language
39
Q

Universal Grammar

A

-all languages share some kind of structure and because of those common grammar rules and patterns we can learn how to speak without ever being formally taught

40
Q

Nativist Theory criticism

A

Genie had a very traumatic upbringing and hard to isolate these effects to a critical period; too many confounding variables

41
Q

What hemisphere is language primarily in?

A

Left

42
Q

Social Interactions Theory says that language is acquired and perfected by interactions between ___.

A

people

43
Q

Social Cognition Model

A
  • observational learning

- our cognition is shaped by our interactions (Bandura)

44
Q

Vygotsky: Sociocultural Model

[Proponent of Social Cognition Model]

A
  1. child observes
  2. develops ability to do what he observes (speak/communicate)
  3. most learning comes from problem solving
45
Q

Bruner: Discovery Learning Theory

[Proponent of Social Cognition Model]

A
  • learn best when discovering things yourself

- even before you see fruits of interaction, child is building up a foundation for communication later

46
Q

Vygotsky believed children learned language best by ____.

A

observation

47
Q

Bruner believed children learned language best by ____.

A

discovery

48
Q

Latent Learning

A

when you are learning something earlier you don’t know that you are learning it until you use it later

49
Q

Language can influence ___ ____.

A

spatial reasoning

50
Q

Where in the brain is Broca’s area found?

A

left frontal lobe

51
Q

Where in the brain is Wernicke’s Area found?

A

left temporal lobe
