TTR = ?
Type Token Ratio
What is Type Token Ratio a measure of?
Measure of semantics diversity
Define TTR (Type Token Ratio).
A ratio of the Number of Different Words (NDW) to the Total Number of Words (TNW) in a sample.
NDW = ?
Number of Different Words
Define NDW (Number of Different Words)
A language sample of fixed length which is a good measure of semantic diversity. Strongly correlated with age.
TNW = ?
Total Number of Words
Define TNW (Total Number of Words)
A general measure of verb output which significantly increases with age.
Describe how TNW significantly increases with age.
- At 3 yr TNW = 205 words in a 50 word utterance
2. At 8 yrs TNW = 379 words in a 50 word utterance
What is the score range that children should exhibit with TTR?
2-8 years = from 0.42 - 0.50
Interpret the meaning of a TTR score > 0.50.
A TTR score > 50 means that there is greater variability and flexibility in the child’s language.
Interpret the meaning of a TTR score > 0.42.
A TTR score < 0.42 means that the child tends to use the same words over and over again.
What do very low TTR scores mean?
Very low TTR scores indicate
- Preservative or stereotypic behavior
- Word retrieval problems
- Restricted vocabulary
