The present masked priming study contributed to the debate by investigating how Chinese EFL learners processed regular English past tense forms. The results show that, for the past tense forms of relatively high frequency, at the early stage of processing, the highly proficient group can make use of morphological rule to decompose regular past tense forms. The lower proficiency level group, however, cannot decompose past tense forms. It is suggested that surface form frequency of past tense inflections and foreign language proficiency are the two factors that affect the way complex words are processed. Our data supports the dual-route model of Declarative-Procedural memory in the past tense debate.展开更多

From the cover, the author knows for what parametric values the system has solutions and at the same time presents the solutions in the form of proper chains. By the refined cover, the author gives a complete classification of the number of solutions for this system, that is, the author divides the parameter space into several disjoint components, and on every component the system has a fix number of solutions. Moreover, the author develops a method of quantifier elimination for first order formulas in finite fields.展开更多
