在二语习得的过程中，仅仅通过加强学习者对其语言特征的注意是不够的。想要

In the process of second language acquisition, it is not enough just to strengthen learners' attention to their language characteristics. If you want to successfully complete the memory and retention of the noticed language features, you need to process these language features in depth. For a long time, many research results in the field of second language vocabulary acquisition have emphasized the positive effect of deep processing on learners' acquisition of new knowledge. The results of such research have confirmed and supported the concept of "Depth of Processing" (Graik & Lockhart, 1972; Craik & Tulving, 1975; Craik, 2002). For this reason, in order to discuss the incidental acquisition effect of vocabulary in depth, it is necessary to explain the hypothesis of information deep processing in detail.

In the process of second language learning, it is not enough simply to strengthen the learner's attention to its linguistic characteristics. Successfully completing the memory and retention of noticed linguistic features requires in-depth processing of those linguistic features. For a long time, many research results in the field of second-language vocabulary acquisition have emphasized the positive effect of deep processing on learners' access to new knowledge. The results of such studies confirm and support the concept of "deep processing" (Graik and Lockhart, 1972; Craik and Tulving, 1975; Craik, 2002). Therefore, in order to further explore the side-by-side learning effect of vocabulary, it is necessary to explain the information deep processing hypothesis in detail.

In the process of second language acquisition, it is not enough to strengthen learners' attention to their language features. In order to successfully complete the memory and retention of the noticed language features, it is necessary to carry out deep-seated processing on these linguistic features. For a long time, many research results in the field of second language vocabulary acquisition have emphasized the positive role of deep processing in acquiring new knowledge. The results of such studies confirm and support the concept of "depth of processing" (graik & Lockhart, 1972; Craik & Tulving, 1975; Craik, 2002).
