3-2.Which verb can converge into adults use more
easily?

• Method Information Entropy
• Information entropy is adopted as an index of
  verb coverage.

The broader a range of events a verb refers to,
the higher value of entropy the verb
receives. (Max log213)
24
3-2.Which verb can converge into adults use more
easily?
Information entropy of 8 high frequent verbs

• For all verbs, the entropy value decreases from
  children to adults.
• The greatest contrast -gtding and na

25
3-3.What factor can predict the ease of learning
verb well?

• Method Multiple Regression
• Independent variables
• production frequency -gt How frequently children
  produced the verb
• correlation with adults -gt How well childrens
  use of the verb converge to adults use

26
3-3.What factor can predict the ease of learning
verb well?

• Method Multiple Regression
• Dependent variables
• Verb coverage
• Event ambiguity
• Corpus frequency(Beijing Language Institute,1986
  )

Event ambiguity
Verb coverage
27
3-3.What factor can predict the ease of learning
verb well?

• Model independent variable production frequency

3years 5years 7years
Event ambiguity -.27 -.39 -.48
Corpus frequency .64 .60 .59
Verb coverage .42 .40 .49

• Corpus frequency is significant for all the
  models Higher corpus frequency-gtHigher
  production frequency
• Event ambiguity decreases from 3years to
  7years(only that of 7years is significant).

28
3-3.What factor can predict the ease of learning
verb well?

• Model independent variable degree of
  convergence with adults.

3years 5years 7years
Event ambiguity -.73 -.81 -86
Corpus frequency .39 -.00 -.17
Verb coverage .09 .18 .19

• Event ambiguity is significant for all the
  models Higher ambiguity-gtLess convergence
• Corpus frequency decreases from 3years to
  7years(not significant).
