Second language development can be viewed as a complex and dynamic process in which learners follow non-linear trajectories and develop their language over a period of time (Larsen-Freeman, 2006). Intrinsic to the view of Complex Dynamic Systems Theory (CDST), a system is composed of hierarchical, interdependent subcomponents (learner, learner…

From a complex dynamic systems (CDST) perspective, language is understood as a dynamic system comprised of subsystems that change and develop over time in response to learner-internal and -external factors (Verspoor et al., 2008). Accordingly, language development is seen as a process responsive to the dynamic interaction between the learner and…

Research on pragmatic competence involving various approaches has received increasing attention since 1980 when interlanguage pragmatics began to flourish. The aim of this systematic review was to examine and categorize contemporary studies on pragmatic competence of EFL and ESL students and to reveal potential moderators, compare results of…

A cross-cultural investigation of lacunae contributes to successful intercultural communication, helping in achieving mutual understanding between cultures and solving communication problems between different nations. This study is aimed at identifying and classifying lexical lacunae in the kinship terminologies of the Russian and Kazakh…

This study examined the crosslinguistic sharing of morphological awareness (MA) in biliteracy development. The analysis included 34 correlational studies with 41 independent samples (N = 4,104). Correlational coefficients were meta-analyzed, yielding four main findings: (a) the correlation between first language (L1) and second language (L2) MA…

This study aimed to investigate the production of stress in English compound nouns and phrasal verbs by L1 Thai learners. Based on the Interlanguage Hypothesis (Corder, 1982; Selinker, 1972), it was hypothesized that (1) there is a positive relationship between English proficiency levels and accuracy in stress assignment in compound nouns and…

This cross-sectional study examined the effects of English language proficiency on Jordanian EFL students' production and comprehension of apology strategies. The participants were 270 Jordanian EFL learners and 90 native speakers of English. Data were collected using Written Discourse Completion Test (WDCT) and Multiplechoice Discourse Completion…

This article shows that first language (L1) transfer may not be effectively maintained in the interlanguage due to confounding factors in the second language (L2). When two factors, "A" and "B," are correlated in the L2, second language learners may only acquire "B," even if "A" is present in the L1.…

This paper investigated the "be"-insertion phenomenon in L2 English. L2 learners often insert "be"-forms before thematic verbs, creating nontargetlike forms (e.g. "She is love ice cream"). Based on L2 data from learners of topic-prominent L1s, a group of researchers have claimed that such "be"-forms are…

This study investigates the role of proficiency in the acquisition of conventional expressions as a pragmalinguistic resource in second-language (L2) Chinese. One hundred and four undergraduates, including 57 learners of Chinese as a foreign language at 3 levels of university instruction and 47 native speakers completed an aural-oral discourse…

Studies adopting a Complex Dynamic Systems Theory framework have often fallen into one of two camps: those investigating variable linguistic subsystems (namely, CAF studies) and those concerned with non-linguistic variables displaying the characteristics of dynamic systems, with little concern for their connection to linguistic development.…

This study investigated the relationship between language proficiency and negative pragmatic transfer from a first language (L1), focusing on the speech act of refusal as realised by American learners of Arabic as a Foreign Language (AFL) in Egyptian Arabic. Twenty American AFL learners (10 intermediate and 10 advanced) and 2 baseline groups (10…

Knowledge of the target specialized language should be of use to English for specific purposes teachers who teach pronunciation. Knowledge of the target learners' first language (L1) should also be useful when these teachers use contrastive analysis, error analysis or interlanguage theory. However, as far as teaching the pronunciation of the…

This interlanguage study examines the L2 mental lexicon of Thai EFL learners with different degrees of language exposure--i.e., the high exposure group and the low exposure group. The scores from the English Language Exposure (ELE) Questionnaire were used to select the two groups of participants. To explore the lexical processing and the…

Morphological complexity (MC) is a relatively new construct in second language acquisition (SLA). After critically discussing existing approaches to calculating MC in first- and second-language acquisition research, this article presents a new operationalization of the construct, the Morphological Complexity Index (MCI). The MCI is applied in two…
