Multiple Choice

Use the following to answer questions :
Scenario I
The scenario is based on and presents results consistent with the following studies:
Snedeker,J. ,Geren,J. ,& Shafto,C.L.(2007) .Starting over: International adoption as a natural experiment in language development.Psychological Science,18(1) ,79-87.doi:10.1111/j.1467-9280.2007.01852.x
Snedeker,J. ,Geren,J. ,& Shafto,C.L.(2012) .Disentangling the effects of cognitive development and linguistic expertise: A longitudinal study of the acquisition of English in internationally-adopted children.Cognitive Psychology,65(1) ,39-76.doi:10.1016/j.cogpsych.2012.01.004
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.
Figure 9.1
-(Scenario I) Snedeker and colleagues (2007) refer to their research program as a "natural experiment." However,for which reason is it NOT an example of a true experimental design?

• A)Participants were not sampled randomly from the population.
• B)The study is not empirical in nature and lacks measurement reliability.
• C)There is no random assignment to groups and no manipulation of an independent variable.
• D)It is difficult to ascertain if the results would generalize to other languages.
