This mixed methods study draws upon theoretical perspectives from usage-based linguistics (UBL) and variationist sociolinguistics to explore four learners' use of second language (L2) Spanish present tense indicative verbal inflectional morphology (i.e., simple present conjugations). The study compares the frequency and distribution of students'…

Multilingualism presents both a challenge and an opportunity for Natural Language Processing, with code-switching representing a particularly interesting problem for computational models trained on monolingual datasets. In this paper, we explore how code-switched data affects the task of Machine Translation, a task which only recently has started…

An elicited production study investigated subject--aux inversion in 5-year-old children with specific language impairment (SLI) and 2 control groups, typically-developing 5-year-old children and 3-year-old children matched by mean length of utterance. The experimental findings showed that children with specific language impairment produced…

This study examined the effect of blended learning through meaning-focused input and output activities on learning collocations. The participants were 124 EFL learners selected from an initial pool of 162 participants, based on their performance on an Oxford Placement Test. The 124 learners were divided into four groups consisting of a…

The present study explores the effects of distributed practice by extending this area of research to L2 learning from audiovisual input. A total of 96 L1 Russian elementary to advanced learners of English watched five episodes of captioned TV series under three viewing distribution conditions: longer spacing of viewing once per week; shorter…

This longitudinal study investigates the effect of mode of reading on the incidental learning of collocations and factors that affect learning. One hundred Vietnamese pre-intermediate learners of English as a foreign language (EFL) were assigned to either an experimental group or a control group (no treatment). In 9 weeks, the experimental group…

This study examines the effect of enhanced input of lexical chunks on the performance of Arabic-speaking English learners' writings. Lexical chunks, containing their forms, meanings, and functions, stored and recovered as a single component in brains, may alleviate language processing problems and increase language proficiency. The research…

The pedagogical value of collocations has gained much attention in recent years. Collocations provide learners with a powerful organizing principle for language. The present study aimed to examine the efficiency of enhancing the input data provided via reading including frequent collocations in writing restatements of EFL students. Therefore, the…

The 'root infinitive' phenomenon in child speech is known from major languages such as Dutch. In this case study, a child acquiring the Papuan language Nungon in a remote village setting in Papua New Guinea uses two different non-finite verb forms as predicates of main clauses ('root' contexts) between ages 2;3 and 3;3. The first root non-finite…

This study examines the effect of textual enhancement on learners' attention to and learning of multiword units from captioned audiovisual input. We adopted a within-participants design in which 28 learners of English as a foreign language (EFL) watched a captioned video containing enhanced (underlined) and unenhanced multiword units. Using…

The present study employed a mixed methods quasi-experimental design to investigate the effectiveness of applying motivational strategies and mental imagery (i.e. visionary techniques) to facilitate second language (L2) vocabulary learning. Four treatment sessions were integrated into a six-week language course offered to 150 intermediate students…

Second language (L2) writing has been determined to be influenced by what is read, with language learners tending to borrow words and short phrases from input texts while writing (e.g., Wang & Wang, 2015). This phenomenon is referred to as lexical alignment. Only one empirical study has investigated the influence that the linguistic complexity…

This study investigates the effects of early second-language (L2) acquisition on introduction of characters in narrative discourse by comparing 5- and 7-year-old monolingual (first-language [L1] = Turkish) and bilingual (L1 = Turkish, L2 = English) children. Turkish does not have a grammaticalized article system like English which enables to…

This study is conducted to examine the effect of input enhancement as an implicit and consciousness-raising as an explicit method of instruction on improving grammatical and lexical collocation knowledge of Iranian EFL learners. To reach this aim, a sample of sixty participants at pre-intermediate level of English proficiency in Gorgan, Golestan,…

The purpose of the present study was to compare the effects of input flooding and input elaboration on the learning of non-congruent collocations by Iranian English as a foreign language (EFL) learners. The participants of the study included 60 EFL learners at the intermediate level of language proficiency who were divided into two equal groups.…
