1、The long-neglected issue of vocabulary acquisition is currently receiving attention in second language pedagogy and research reflecting the importance always accorded it by learners. But it is still far from clear how le

2、arners acquire vocabulary or how it can best be taught. As direct vocabulary instruction clearly fails to account for the substantial vocabulary knowledge of intermediate and advanced learners, there has been a broad acc

3、eptance that learners could acquire a large proportion of vocabulary incidentally from written contexts. Incidental vocabulary learning has been regarded as common for adults' life-long learning of a foreign language, w

4、hich is therefore encouraged to L2 learners for enhancing vocabulary ability. Nonetheless, it is not clear if, or to what extent, different L2 learning tasks have different impact on incidental vocabulary learning. Th

5、is study aims to examine whether retention of vocabulary acquired incidentally is contingent upon the amount of task-induced involvement load, a construct proposed by Laufer and Hulstijn (2001) in the Involvement Load
