Chapter 9: Language Development Flashcards
What are the four components of language?
- Phonology
- Semantics
- Grammar
- Pragmatics
What does phonology refer to?
The rules governing the structure and sequence of speech sounds.
Which component of language involves vocabulary (the way underlying concepts are expressed in words and word combinations)
Semantics
What are the two sub-components of grammar, and what do they refer to?
- Syntax: The rules by which words are arranged into sentences.
- Morphology: The use of grammatical markers indicating number, tense, case, person, gender, active, passive, and other meanings.
What does pragmatics refer to?
The rules for engaging in appropriate and effective communication. Because society dictates how language should be spoken, pragmatics involves sociolinguistic knowledge (interaction rituals such as verbal greetings and leave-takings).
True/False:
The four components of language are independent from each other.
False. The four components are interdependent and acquisition of each facilitates mastery of the others.
According to the behaviourist approach, proposed by Skinner, language is acquired through _______ ____________.
operant conditioning (i.e. parents reinforce children’s sounds that most closely resemble words).
Why is the behaviourist approach to language development not widely supported today?
Imitation and reinforcement do not adequately explain how children acquire language.
Who proposed the nativist theory of language development?
Noam Chomsky
What does language acquisition device (LAD) refer to?
An innate system that permits children, once they have acquired sufficient vocabulary, to combine words into grammatically consistent, novel utterances and to understand the meaning of sentences they hear.
What does Broca’s area support?
Grammatical processing and language production
What does Wernicke’s area support?
It plays a role in comprehending word meaning
Where is Wernicke’s area located?
left temporal lobe
Where is Broca’s area located?
left frontal lobe
True/False:
Broca’s and Wernicke’s areas are solely responsible for their specific language functions.
False. Patients with Broca’s aphasia (impaired pronunciation and grammar) and patients with Wernicke’s aphasia (meaningless streams of speech) have injury that spreads to nearby cortical areas, and have widespread abnormal activity in the left cerebral hemisphere.
True/False:
The brain is not fully lateralised at birth.
True. Brain lateralisation is complete by around puberty.
What are the four limitations of Chomsky’s nativist perspective of language development?
- Researchers have great difficulty specifying Chomsky’s universal grammar.
- Chomsky’s assumption that grammatical knowledge is innately determined does not fit with certain observations of language development.
- Chomsky’s theory lacks comprehensiveness. It cannot explain how children weave statements together into connected discourse and sustained conversations. Chomsky did not dwell on the pragmatic side of language, so his theory grants little attention to the quality of language input or to social experience in supporting language progress.
- The nativist perspective does not regard children’s cognitive capacities as important.
What does the statistical learning theory propose?
Children have the ability to analyse sound streams to identify which sounds often occur together and which do not, which helps children to discriminate words in fluent speech.
Social interactionist theories propose that children acquire language due to which three influences?
- Native capacity
- A strong desire to understand others and be understood
- A rich language environment
Newborns are especially sensitive to the _____ _____ of human voice
pitch range
Define phonemes
the smallest sound units that signal a change in meaning, such as differences between the consonant sounds in pa and ba
What is the tendency to perceive as identical a range of sounds that belong to the same phonemic class called?
categorical speech perception
What is infant-directed speech (IDS)?
A form of communication made up of short sentences with high-pitched, exaggerated expression, clear pronunciation, distinct pauses between speech segments, clear gestures to support verbal meaning, and repetition of new words in a variety of contexts.
Around 2 months, babies begin to make vowel-like noises. What is this called?
cooing
