This study investigated how input frequency (i.e., type frequency and token frequency) and proficiency levels enhanced the perception of English nominal suffixes by first language (L1) Thai learners. Based on the Usage-based Account (Tomasello, 2003), it was hypothesized that input frequency, i.e., token frequency (frequency of derived forms…

This study is a replication and extension of Morgan-Short et al.'s (2018) investigation into the role of attention in input processing by L1-Polish learners of L2-Spanish, with proficiency and language of assessment explored as two key methodological factors. Our aims were twofold: to investigate learners' comprehension in different conditions…

This research investigated the impact of processing instruction (PI) on the acquisition of the English third-person singular present tense by Chinese English-as-a-foreign-language (EFL) learners and whether this effect would extend to the acquisition of other language components. This study featured the pretest-immediate-posttest design and…

When linguistic input contains inconsistent use of grammatical forms, children produce these forms more consistently, a process called "regularization." Deaf children learning American Sign Language from parents who are non-native users of the language regularize their parents' inconsistent usages. In studies of artificial languages…

This study investigates the effects of motivation and structured input on the acquisition of English past tense regular forms. The role of motivation in the positive effects generated by processing instruction has been investigated in one previous study (Farhat & Benati, 2018). However, more research is needed to generalize the initial…

This article reports on two studies, testing how three different types of input (skewed first, skewed random and balanced) affect second language (L2) learning of English present counterfactual (IF-Is) and past counterfactual (IF-IIs) conditionals, two constructions differing in complexity. The experiment included a proficiency test, a pretest, a…

The present research sought to explore the combined contribution of input flooding, visual input enhancement, and consciousness-raising tasks on noticing and intake of the present perfect tense among Iranian EFL learners. Using a nonrandomized control group pretest-posttest design, the researchers attempted to see if instruction could enhance the…

In a masked morphological priming experiment, we compared the processing of derived and inflected morphologically complex Turkish words in heritage speakers of Turkish living in Berlin and in native speakers of Turkish raised and living in Turkey. The results show significant derivational and inflectional priming effects of a similar magnitude in…

This study investigated the effect that the salience of an L2 form has on learner noticing and production of the form. The study also explored the effects that task type (output vs. input) has on form noticing and production. The study targeted three Arabic forms: a low salient form (the future tense) and two salient ones (time telling and time…

The study investigates to what extent English as a second language (ESL) learners develop explicit and automatised explicit knowledge of two target-forms (third person singular 's' and future conditional if-clause) after input and output based instruction and whether learning effects differ depending on the target forms. The study follows a…

Previous research has demonstrated the effectiveness of captioning in second language (L2) comprehension and vocabulary learning. However, little attention has been paid to its potential in supporting grammar development, another challenging area in L2 acquisition. In this research, we used a randomised control design to investigate the role of…

In our globalised world, the desire for the acquisition of English has led to increased research into the appropriate pedagogical approaches for learning and teaching the language. This manuscript focuses on the use of learners' mother tongue in the learning and teaching of English in an effort to identify ways in which cross-linguistic…

This study compared the effectiveness of balanced and skewed input at facilitating the acquisition of the transitive construction in Esperanto, characterized by the accusative suffix "-n" and variable word order (SVO, OVS). Thai university students (N = 98) listened to 24 sentences under skewed (one noun with high token frequency) or…

Despite an increased emphasis on form-focused instruction (FFI), the use of the computer as a grammar tutor has remained largely unexamined for nearly two decades. With new technologies at hand, there is a need to take a fresh look at online grammar tutors and link designs more strongly to contemporary second language acquisition (SLA) principles…

This investigation examined two techniques that may help learners focus on second language (L2) constructions when recasts are provided during meaning-based communicative activities: altering the cognitive complexity of tasks and manipulating the input frequency distributions of target constructions. We first independently assessed the validity of…
