The functional roles of lexical devices in second language learners' encoding of temporality: A study of Mandarin Chinese-speaking ESL learners.

The present study investigates the functional roles of two lexical devices, past-time temporal adverbials and frequency adverbs, in Mandarin Chinese-speaking ESL learners' encoding of temporality in their English interlanguage. The results of the present study indicate that past-time temporal adverbials are facilitative in Mandarin Chinese-speaking ESL learners' encoding of past time. Meanwhile, the existence/absence of the matrix agreement, which is a linguistic device that has not been discussed in previous studies, may also lead to learners' different reactions. The results of the present study also show that the introduction of frequency adverbs is associated with a higher usage rate of the present tense and causes more difficulty in a past tense context. This association is found to exist not only in learners' data, but also in English native speakers' data. The present study contributes to our understanding of the development of second language learners' expression of temporal locations and relations. [ABSTRACT FROM AUTHOR]
