The effect of explanation to others on the speaker's comprehension: Using mother tongue and second language
Recent studies have shown that giving an explanation improves speaker' s comprehension when mother tongue is used. This effect is expected to appear in the use of second language as well. In the study, it was investigated what kind of explanation facilitated the acquisition of a better comprehension. The explanation was implemented under Chinese or Japanese language condition. Twenty-three advanced and pre-advanced Chinese learners of Japanese participated in the experiment that giving explanation after reading a text on statistical dispersion. They were randomly assigned with mother tongue condition or Japanese condition. Protocol analysis showed that meta-explanations and interpretive utterances were positively correlated with comprehension under Japanese explanation condition; while for mother tongue explanation, pre-existing knowledge has a big impact, thus, comprehension can not only be judged by the utterance of explanation.
