Word Learning Flashcards
Why is word learning hard?
List 2 main reasons
1) Because things can’t just be “point and name”
2) The mapping problem
(+ Difficult to get the meaning right (under-extension and/or over-extension)
True or False?
Point and name is very common (and universal)
False
Point and name is not common (and not
universal)
When children usually point and name, what type of words to they mainly say?
Nouns
Define the mapping problem
When there is potentially an infinite number of possibilities for mapping between a word and potential referents
Simply = When a word can mean a range of different things
e.g. Gavagai can mean dog, fast, brown, paw, ear etc

What is the GAVAGAI problem?
A made up word by Quine (1960) used as an expression of a completely foreign language that is not easily translatable into a known language as it can mean a range of different things
e.g. Gavagai can mean dog, fast, brown, paw, ear etc

GAVAGAI problem
Word learning is hard because children struggle to get the meaning of the word right.
Sometimes they express an under-extension of a word
What does this mean?
When the meaning they have for a word is too narrow compared to the actual meaning of the word
e.g. “Dog” might mean family dog but not other dogs they see
It’s as if the word “dog” is almost taken as a name and not as a word
When the meaning they have for a word is too narrow compared to the actual meaning of the word
e.g. “Dog” might mean family dog but not other dogs they see
It’s as if the word “dog” is almost taken as a name and not as a word
This is known as…?
Under-extension
Word learning is hard because children struggle to get the meaning of the word right.
Sometimes they express an over-extension of a word
What does this mean?
When the meaning they have for a word is too broad compared to the actual meaning of the word
e.g. “Dog” might mean any four-legged animal they see including pig, horse, lion

Infants’ first words come from a range of categories
Name 4 main categories
1) Nouns (objects – dog, cat & proper names - Mummy)
2) Verbs (action words – jump, get)
3) Social routines (bye, hello, please)
4) Adjectives (descriptions – cold, dirty)
In early language, infants often vocalise single words
True or False?
True
e.g. “Apple” instead of “An apple”

The usage of articles (a, an, the)
Define early noun bias

Describe the natural partitions hypothesis
The reason for early noun bias is said to be because concrete objects and entities are easier to individuate from surroundings

This is known as…?
Natural partitions hypothesis
Why do infants not have a bias for verbs or adjectives?
Because actions, states and descriptions tend to apply TO entities labelled by nouns
Thus, they are less clearly defined in space and time

What does socially mediated word learning propose?
List 4 things
1) Not all early words are nouns (hello, bye)
2) Not all early nouns are discrete objects (breakfast)
3) Learning occurs in situations where easiest to read adult’s intentions, irrespective of word class.
4) Happens often with nouns

2) Not all early nouns are discrete objects (breakfast)
3) Learning occurs in situations where easiest to read adult’s intentions, irrespective of word class.
4) Happens often with nouns
What does this suggest about word learning?
Infants follow socially mediated word learning
Infants use words in a variety of situations
Name 3 situations and give 2 examples for each
1) Names for people and objects
e.g. Daddy, spoon
2) Names for actions
e.g. open to request that a door be opened, a jar be opened etc.
3) Names for properties
e.g. gone, more, dirty
1) Names for people and objects
e.g. using “Daddy” when he is not around, spoon
2) Names for actions
e.g. open to request that a door be opened, a jar be opened etc.
3) Names for properties
e.g. gone, more, dirty
What does this suggest about infant word learning?
Infants use words in a variety of situations
There is some flexibility for the words they use as they are able to apply words they’ve learnt in a particular context to a different context
Word used only in specific context or specific exemplar
This is known as…?
Under-extension
Words used in specific contexts where adults would use in a wide range of contexts
This is an example of…?
Under-extension
Give 3 examples of when infants would use words in specific contexts where
adults would use in a wide range of contexts
1) saying “bye” only when putting the telephone receiver down
2) using “there” only when putting an object in a location (but not to an object “over there”)
3) refering to the word “flower” only to mean a “rose” and NOT other flowers
1) saying “bye” only when putting the telephone receiver down
2) using “there” only when putting an object in a location (but not to an object “over there”)
3) refering to the word “flower” only to mean a “rose” and NOT other flowers
What does this suggest about early word knowledge?
Even though there is a slight flexibility in which the infant is able to use certain words in a variety of different contexts, in some cases, this is not the case
Word used beyond its true meaning
This is known as…?
Over-extension

When the infant mixes up the concept of one item with the category of another item
e.g. the concept of ball is incorrectly in the same category as apple

This is an example of…?
Category error
What are the 2 over-extension errors infants make in early word production?
1) Category error
2) Vocabulary limitations
Why do infants make category errors?
They have vocabulary limitations
e.g. lacking the vocab of “ball”
List the 4 innate constraints on early word learning
1) Object constraint
2) Whole-object constraint
3) Principle of contrast
4) Mutual exclusivity
Describe object constraint
List 2 points
1) When an adult points to an object and says a word, a child assumes this word labels the object
Simply = Words refer to objects
2) This explains noun bias
