In my PhD project, I investigate roles of L1 features, positive evidence and interface on L2 acquisition, using data from an empirical study regarding L2 acquisition of Chinese and Thai nominal phrases.
In previous presentations, I have presented linguistic background and methodology of my study, as well as some results. In this presentation, I will continue with results of the study, both an acceptability judgment task and a self-paced reading task.
In general, results from these tasks indicate that:
1) It is more likely that learners will successfully acquire a target language feature when learners’ L1 and target language features are the same, compared to when the two features are different.
2) However, the L1 positive transfer effect is not absolute. The fact that L1 and target language features are the same does not always guarantee that learners can behave native-like under all criteria.
3) It is more likely that learners will successfully acquire a target language feature when positive evidence in a target language is available, compared to when the input is not available.
4) Linguistic phenomena that have interface properties may be acquired later than those which have narrow-syntax properties.
