This study aims to investigate the attrition rate of EFL concrete and abstract vocabulary among continuing and non-continuing Iranian female and male English language learners across different proficiency levels. They are students of a University and majored in different fields (between 20 and 25 years old). There was no treatment in this study where the researcher compared two groups on the same variables. Hence, the design of the current study is an ex-post facto design. A 40-item vocabulary test which varied across two proficiency levels are used to measure rate of vocabulary attrition as the instrument of this research. In the two stages, after an interval of three months, the students are taken the same tests. The results revealed that there was no significant difference between EFL attrition rate of abstract and concrete nouns among the continuing students across different proficiency levels. However, this hypothesis was rejected for the non-continuing learners at intermediate and advanced proficiency level.

The conception of loss in language skills occurred in a conference at the University of Pennsylvania (UPenn) in 1980. This conference was dedicated to the theoretical basis of research in the field of language attrition and other related conferences that probed the process of language loss as a natural disorder from many other perspectives. Kopke (2004) stated that "attrition refers to the natural (non-pathological) loss of a language in bilinguals; generally speaking, changes in the linguistic environment and termination of an instructional program may lead to attrition"(p.15).In terms of language learning, researchers have used the same definition to develop a framework which involved divergent methods of data collection, sampling and instrumentation on language attrition in papers and publications. This taxonomical framework was the one provided by Van Els (1986, as cited in Kopke and Schimd, 2004) which was as following categories:1. L1 loss in L1 environment: Dialect loss 2. L1 loss in L2 environment: Immigrant 3. L2 loss in L1 environment: Foreign language attrition 4. L2 loss in L2 environment: Language reversion in elderly peopleThe main phases reported in the field of language attrition are the above categories as the framework has divided the field of attrition into four simple and discrete categories. But, in order to gain a better and clearer picture of the concept of attrition, other methodological issues such as the distinction between attrition in adults and children, the effect of age at the amount of attrition, the effect of age at bilingualism, the effect of gender at the amount of L2 attrition and so forth also needs to be taken into consideration.
Stages in Language AttritionWeltens and Grendel (1993) suggested that in "the first stage of language attrition that it t...
