Understanding Words and Sentences Flashcards
What does the brain have?
An underlying system that it uses to categorise and organise words hierachally
What is a free morpheme?
A single word - can’t be broken down any smaller to have a meaning
only one basic unit of meaning - non-decomposable
e.g. dog
What are bound morphemes?
Complex words - can’t stand on its own
e.g. dogs
When do children learn morphology?
As the acquire language
the wugg test
even without seeing words before, can still combine them with what you know to produce the correct word
What is the mental lexicon?
2 ways that words are stored: storage vs computation
full listing - words must be looked up in the lexicon as whole words
full parsing - words must be decomposed into elements, words are broken down and stored into the smallest word with rules next to them
Are words stored as wholes or broken down?
Some are stored as wholes and some are broken down depending if the word is regular or irregular
idiosyncratic words must be stored e.g. find - found, there is no rule so just have to store found
fully transparent words - walk - walked, don’t need to store it as recreate it by adding an ending
What is a dual route model?
Both direct lookup and computation used
What affects whether storage or computation is used?
Frequency of the word
Why does frequency of a word affect the mental lexicon?
If a complex word is common enough, it can eventually become lexicalised
e.g. home+work = homework (compound) - this eventually becomes its own word
What does lexicalisation mean?
Stored on its own as a word
How go test whether frequency aids lexicalisation?
Whole compound - homework
Constituents - home and work
if response time changes depending on whole compound - shows it has been lexicalised
if response time changes depending on constituent frequency - shows the constants are accessed during processing
Evidence to support frequency aiding lexicalisation
Eye tracking with compound word - gaze was influenced by all 3 frequencies, shows dual route
no escape from morphemes - all words are stored in pieces no matter how complex they are
interaction between whole compound and constituent frequencies - readers integrate multiple strategies, use both ways and which one gets there first, is the interpretation that you use
Why is evidence conflicting?
Different techniques:
Eye tracking
MEG
Reaction times
Different types of constructions:
Afflixing
Inflection
Compounding
Different influences:
Frequency
Family size
Meaning
What is language designed for?
Communicating
What is a maximally expressive language?
Having a different word for each unique event, thing, person, action etc
advantage - minimal room for misunderstanding
disadvantage - overload with unnecessary detail - communication becomes impossible
