In the research, there are two experiments, one using the translation
paradigm while another is using the elicited production paradigm. Participants
are required to translate an English sentence to Cantonese and the elicited
production paradigm requires the participants to repeat the content of
the sentence by answering probe questions. Both experiments have similar
result that the complexity of sentence affects the sentence construction
in production. People will construct the sentence in a more efficient way.
This is consistent with our hypothesis in double-verb structure, to minimize
the domain for better speech production. However, since the translation
paradigm is a fresh idea, further research should be done in verifying
the reliability of this paradigm.
