Q

How do children learn words?

A

They have to:
segment the speech/sign stream into ‘units’ identified later as words.
analyse the world into objects and events.
map speech/sign units onto these objects and events (“reference”).

Q

Why are nouns most common first words?

A

Conceptually/perceptually distinct.

Linguistically predictable.

Limited morphological modifications.

Frequent in the input to children – labelling occurs often in Western culture.

English word order places nouns at the end of the utterance where they are most salient and they are usually stressed.

Babies/toddlers have lots of experience with objects represented by nouns.

17
Q

What are quasi words?

A

Phonological forms used consistently for a particular meaning, but with no phonological relationship to the adult word.

May also be referred to as “phonetically consistent forms”.

Quasi-words, babble and gestures continue to be used alongside early words.

Child may also use whole learned adult phrases as a single word e.g. “wassat?” (unanalysed wholes).

18
Q

What are the intentions of first words?

A

A single word may:

  • Label an object or action.
  • Request something.
  • Request for something to continue/ happen again.
  • Gain someone’s attention.
  • Serve other social functions e.g. greetings.
  • Answer a question.
  • Ask questions (+ intonation).
  • Indicate possession / location / attribute.
19
Q

List some Difficulties in Word Learning

A

Segmenting the speech stream is difficult

Hearing the same word despite variations in speaker voice.

Mapping words to meanings:
Over/under generalisation.
Part or whole?
Mapping of action words / abstract words.

20
Q

What’s undergeneralisaation?

A

Under-generalisation - restricting use of a word to just one particular referent e.g. only using the word “cat” to refer to own cat.

21
Q

Whats undergeneralisation?

A

Over-generalisation – e.g. using the word “cat” to refer to all furry four-legged animals including dogs.
Definitions are gradually modified by real-world experience and exposure to adult language.

22
Q

What’s Quine’s problem?

A

A linguist visits a foreign land and hears someone say the word ‘gavagi’ as a rabbit runs. There are a number of possible word-to-world mappings in this situation.

Issue with labelling; what word does the child understand by the meaning?
