Language Development Flashcards
What are the 4 components of language?
Phonemes
Morphemes
Syntax
Pragmatics
What are phonemes?
What are 4 facts?
Smallest units of sound recognizable as speech rather than random noise
1) Helps us distinguish words from one another
2) Examples: consonants and vowels
3) Each of the world’s languages have a unique set of phonemes
4) Not all languages use all phonemes
What are morphemes?
What are 3 facts?
The smallest meaningful units of language
1) What is the smallest number of phonemes needed to make a morpheme?
2) How can you tell whether a group of sounds is a morpheme or not?
3) Examples: “me”, “giraffe”, “text””ing”, “un””fair””ly”, “doctor”
What is syntax?
What is one fact?
The rules governing how words are combined to form meaningful phrases and sentences
- Syntactical rules differ across languages
–English: I went to the beach yesterday
–Spanish: Ayer fui a la playa: Yesterday went to the beach
–French: Je suis allé à la plage hier: I am gone to the beach yesterday
What are pragmatics?
What are 4 elements that they can include?
Part of language that do not consist of spoken words, but can nonetheless change meaning
- Can include elements such as:
1) Context
2) Intonation (how a word is said, e.g. “Oh, that’s great news…”)
3) Facial configuration
4) Body language
Explain pragmatic development
Children develop an understanding of pragmatics from early infancy (e.g. response to pointing), and it continues throughout lifespan (important to learn awareness of culture and meanings aside from literal spoken word meaning)
What are 4 facts about phonological development?
1) Before birth to adolescence
2) Learn to differentiate (perceive) sounds of native language
3) Learn to produce sounds of native language
4) Much perceptual phonological development complete by 10 months
4 facts about semantic development?
1) Birth throughout lifespan
2) Very high rates of acquisition after 10 months through early school age
3) Requires ability to segment speech (identify phonemes)
4) Mostly nouns
3 facts about syntactic development
1) Telegraphic speech: often two word utterances (“more milk,” “eat cookie”)
2) Pronouns start being used in the third year (24-36 months)
3) Development slows by 5-6 years of age, at this point child knows the syntax of their native language (order of which words are said)
What are 2 pieces of evidence that support the notion that there is a critical period for language acquisition?
- Comparing adult second language learners to child second language learners: often the child learner does a better job which suggests that learning language in childhood is easier for us
- Evidence from ASL learnings:
Comparing those who learned ASL in adulthood vs. childhood: found that those who learned ASL in childhood made less mistakes and were more fluent
ASL instruction is most beneficial as soon as child identified as being deaf
What is the Quinean Reference Problem?
All labelling is inherently ambiguous so how do kids figure out meaning of words? If you point to an object and label it, how does the child so quickly know whether you are referring to the whole object, a part of the object, the colour of the object, or some other property of the object?
5 explanations to the Quinean Reference Problem?
1) Whole-object bias: if you hold an object and say this is “water bottle,” they will see that it is a water bottle and not that you are referring to the cap or design.
2) Mutual exclusivity: each label applies to one and only one object; each object has one and only one label
3) Basic level bias: when we hear a word, we tend to think of it as being that basic level; e.g. someone points at a rabbit and says “rabbit” you interpret that at the basic level (‘rabbit’) and not the superordinate (‘mammal’) or subordinate (‘arctic hare’)
4) Linguistic context:
Grammatical/syntactic cues, child will take these cues to interpret what you are referring to:
- “He is gavagaying!” Talking about a verb, what is the person doing at that moment?
5) Pragmatic clues: parent points at objects, and says “this is a waterbottle.”
What are the 4 hypotheses for language development?
Behaviourist account, nativist account, connectionist account, statistical learning account
What are three facts about behaviourist account?
- Caregivers support language learning through reinforcement
- Parents correct children when they make mistakes
- Parents reward children when they are correct
A) Who pioneered nativist account?
B) What are 6 Facts?
A) Chomsky
B)
1) Brain has a language acquisition device, specialized part of brain for learning language
2) A dedicated language module has involved in humans (modularity hypothesis)
3) Specific brain areas are used for language
4) Universal grammar (all languages follow a basic structure, and once your brain figures out the innate structure of the language, it turns on and one can acquire language)
5) All (typically developing) children acquire language
6) Evidence from Nicaraguan Sign Language (created a language out of nothing, shows the brain’s innate predisposition towards this basic language structure)
4 facts about connectionist account?
1) Opposite of nativism
2) Children learn language the same way that they learn everything (general-purpose associative learning mechanisms)
3) Computer simulations show that some features of language can be learned with repetitive input
4) Parallel processing allows for a lot of information to be processed at once (e.g. processing word form, meaning and grammar)
What are 4 facts about the statistical learning account?
1) Learn from environment, nothing special about language
2) Children sensitive to the statistical probabilities of the input (hard sound like ‘k’ is likely to be followed by soft sound like ‘a’), what phonemes are likely to follow other phonemes
3) Not language specific (i.e. not evolved specifically for language learning) but used in service of learning language ((conditional probabilities)
4) Can learn rules as well as sound (phoneme) patterns
What are two concepts of word learning?
1) Fast mapping (ability to acquire word quickly on minimal information: quickly pair word with object, do not need lots of repetition
2) Syntactic bootstrapping (use syntax to bootstrap/figure out meaning of word)
What are 2 concepts on conversations?
1) Children talk to themselves as a regulatory function (to help organize their thoughts)
2) Collective monologues: taking turns in conversation that have no correlation with each other
What are gender differences at age 1?
- Toy preferences as early as 1 year
Not only preference for gender typical toys but neutral toys if believed gender appropriate (e.g. more likely to play with an object if they saw someone of the same presenting gender playing with it first)
