Word association and the mental
lexicon
Cognitive processes -- how words and meanings
are organized mentally (unobservable)

How words are stored in the mental lexicon







L1 / L2 equivalence (cognates in related languages e.g.
cream in English and crème in French)
Orthographically (words that have similar spelling)
Phonologically (rhyme, alliteration, stress pattern, etc.)
Semantically (synonyms, antonyms, hyponyms e.g. color red)
Collocationally (e.g. make – a wish, catch – a bus)
Morphologically (e.g. defensive-offensive; televisiontelescope)
Encyclopedic associations (based on our knowledge /
experience of the real world)
6
Meanings of words

Meanings of words are often understood in
relation to other words (like a web)
e.g. you understand the meaning of ‘cold’ through
your understanding of ‘hot’
 e.g. you understand the meaning of ‘roses’ through
your understanding of ‘garden’, ‘flowers’ or ‘lilies’

7
Word Associations and Language Proficiency


How words are organised / stored in the brain is
an indicator of language proficiency level
Or how “native-like” you are
8
Paradigmatic associations
Always belong to the same word class
 Substitutable in syntactic strings
 More semantics-oriented (synonyms, antonyms, superordinates, or hyponyms)
 E.g. I want to get a doggie for my daughter.
pet
Terrier
cat
wombat

Syntagmatic associations
Usually belong to a different word class, but sometimes can belong to the same word class
Collocate well with prompt words in a grammatical string
 More grammar-oriented (in a grammatical string)
 E.g. Dogs bark.
E.g. Walk the dog.
E.g. Dog collar

Phonological associations / Clangs
E.g. dog - fog
E.g. hockey - hockey

L1 mental lexicon

Phonological
Syntagmatic Paradigmatic
( developmental process)
( younger children
older children )

Commonness / Homogeneity in the their mental
lexicons (native speakers tend to give the same
word associates – more stable / consistent
associations)

e.g. blanket: bed, warm, sheet, electric, cover, warmth,

wool, soft, bath, snow

11
L2 mental lexicon similar to
L1 mental lexicon
Earlier studies found NS had more paradigmatic
associations than NNS. But later studies (e.g.
Zareva, 2007) found the same shift in L2
learners, as they get more proficient in the
language, and as they grow older
Phonological
Syntagmatic
Paradigmatic
12
Looking at your word associates
1.
What kinds of associations do you have most
(phonological, syntagmatic, paradigmatic) in
your WA tests?
13
Pedagogical Implications
Developmental/ cognitive aspect:
 Younger learners tend to favor syntagmatic
associations: dog-bark

Older learners tend to favor/ are capable of
handling paradigmatic associations /
semantically-related groups e.g. synonyms,
antonyms, hyponyms: dog-cat or dog-pet
14
Superordinates and Hyponyms
???
Lion
Tiger
Horse
Sports
???

15
Superordinates and Hyponyms
Flat
Living room
Bedroom
Fridge
Kitchen
Bathroom
Utensils
Saucepan
Frying pan
16
Word retention




teach 8-12 vocabulary items in a 60-minute
lesson (Gairns & Redman, 1986)
The chances of learning and retaining a word
from one exposure is only 5-14% (Nagy, 1997)
5 – 16 times for a word to be learned (Zahar,
Cobb & Spada, 2001)
An important role for recycling (revisiting) of
the vocabulary learnt
Importance of Revision
Spaced / Distributed Repetition
Recycling of vocabulary






Horst & Meara (1999) – far more vocab is learnt if the same text
is read several times (the first reading focuses on understanding
meaning, while the later readings focus on the forms)
Following a piece of news for several days (word repetitions and
synonyms); encountering the same words in different contexts
Vocabulary quizzes
Different parts of speech (e.g. “shoulder” as a noun, and as a
verb)
Other meanings (polysemy) of a word (e.g. “head as a body part,
the school head, the department head, head of a queue)
Replacing general words by specific words (e.g. nice – attractive,
elegant, terrific)
