Scenario I
The scenario is based on and presents results consistent with the following studies:

Language development occurs in orderly stages,beginning with one-word utterances and progressing to two-word utterances,simple sentences containing function morphemes,and the emergence of grammatical rules.Psycholinguists have attempted to determine if language development is a consequence of cognitive development or if it reflects linguistic processes that occur independently of general cognitive development.Studies on the acquisition of a second language in internationally adopted children have provided insight into this research question.In a series of studies,Snedeker and colleagues (2007,2012)studied the acquisition of the English language in adopted preschoolers from China.These children had no exposure to the English language before being adopted by families in the United States.

Quizplus · Accepted Answer

Data set B shows that the percentage of verbs in the vocabulary of internationally adopted preschoolers from China increases at a slower rate than that of monolingual infants, even after 24 months of exposure to English, suggesting that cognitive factors may play a role in language development. Data sets A, C, and D show similar rates of increase, indicating a more language-specific process.
