The result shows: 1 Further pairwise comparisons suggest that for five-year-olds, children"s overall performances (i.e., scores of I+A+O) of the four verb types (i.e., Specified, Open, Control, Filler) are all significantly different from each verb types, with Control scores the highest, Filler the second, Open the third, and Specified the last (i.e., C > F > O > S).
for seven-yearolds, children"s overall performances of Specified and Open verbs are significantly different from the other three verb types, but Control and Filler verbs are not significantly different from each other.
