The development of using function word "zài" to learn novel verbs in young Mandarin speakers.

The present research examined whether Mandarin-speaking children could use function words to learn novel verbs and recognize verbs in a new sentential context. In Experiment 1, 3- to 6-year-old children were taught two novel verbs supported by the verb marker "zài." The 5- and 6-year-old children successfully used the function word "zài" to learn novel verbs, but the 3- and 4-year-olds failed to interpret the novel words as verbs.
