Lexical Development Flashcards
What will a child begin with
A child will begin by producing proto-words that hold meaning for them and the
caregiver !
Katherine Nelson (1973) identified 4 categories for child lexical development:
- Objects/people (60%),
2. Actions/events, 3. Describing/modifying, 4. Personal/social (8%)
What supports Nelson
the four categories infants supposedly find easiest to
understand (Spelke)
Spelke- infants find words in these four categories easiest to understand
Cohesion: clearly defined in shape! Continuity: doesn’t disappear! Solidity: is solid!
Contact: doesn’t have a life of its own!
Who does Spelke support
Supports Piaget’s idea that children don’t learn words unless they understand the concept behind them
A child’s first words
A child’s first words will often be concrete, common nouns from semantic fields like food, body parts and animals!
Grammatical/function words are notably absent in the early lexicon
How do children acquire language
- It is clear that children acquire language exponentially !
- From 2-3 years, s/he may be learning on average 10 words a day!
- Carey (1978) called this rapid word-learning ‘fast mapping’!
Rough measure of how many words a child acquired at different ages 1-3
1-1.5age=50,
2age=200-300,
3= 900-1000
Rough measure of how many words a child acquired at different ages 4-16 then 12 years
4= 1500-1600
5= 2100-2200
6= 2600 (active), 20,000-24,000 (passive)
12= 50,000 (passive)
