Motor Development
Semantic development is closely related to development in ________, ______, and ______ abilities
motor, social, cognitive
The better a child’s abilities in those areas, the more language he ______s and _______
receives, practices
18-24 months: expressive vocabulary goes from
50 to 200-300 words*
By 36 mos of age, children will have expressive vocabularies of ______words
900-1000 words
Many children have receptive vocabularies of up to 14,000 words
By 6 years of age
at __ years old, by Kindergarten, they should be using 2,100-2,200 words
5 years
Fast mapping —a hypothetical process where children associate a word and its referent after the first or initial exposure
• Extended mapping —new words are gradually expanded and modified as additional experiences become available
For example:**
• A child might learn the word “horse” when he goes on a merry-go-round with his dad
• Then, he extends his understanding as he sees horses in pastures and reads about them in books

What study?
Montgomery 2011
when these words…**
• Are composed of phonemes that the child can produce (“cow” vs. “synthesize”)
• Are object words as opposed to action words
• Are reduplicated syllables (mama)
Children learn more quickly when these words
- Simultaneously pairing a word with its referent
- Letting th
- e new word be the only new word in a certain context.
We can help children learn new words faster by

extended mapping behind for a 4 year old with LI
- These words are adjective pairs that indicate dimensions of objects
- E.g., big/little, wide/narrow
- Usually, big/little is the first pair to be mastered (3 yrs.)
Dimensional words
- These terms express relationships in domains such as color, location, size, family roles, and temporal sequences
- These terms can be hard because they are often relative
- For example, whose mom is the skinniest? Whose dad is the tallest?
Development of Relational Terms
- By 4-5 years old, most preschoolers can name blue, red, yellow
- More subtle color shades are acquired later
Color words
- Indicate location of a referent in relation to some item
- In, out, behind, under
- By 5 years, most preschoolers have mastered most spatial relations
- Important for math!
Spatial words
- The first ones to develop usually refer to immediate family—mother, father, sister, brother
- Then, children gradually learn other layers of relatives
Kinship terms
