In this final article in this guest-edited issue on synergies in second language acquisition and teaching (SLA/T), we attempt to bring together the main content of this issue in an overall, combined synergy statement, concluding this project as a whole. Let us remind readers of the project: A shared effort by 17 scholars taking 11 different…

Studies into the role of audiovisual input and captions (i.e., subtitles in the same language as the audio) for L2 learning have shown that such input can positively influence L2 learners' acquisition of lexical items. Few studies have explored the effects of captioning on learners' capacity to segment the speech stream. This study investigates…

The current research examined whether children's expectations about labeling conventions can be influenced by limited exposure to a foreign language. Three- to four-year-old Korean children were presented with two speakers who each assigned a novel label either in Korean or Spanish to a novel object. Children were asked whether both labels were…

Second language (L2) viewing with captions (i.e., L2 on-screen text) is now a proliferating as well as promising area of L2 acquisition research. The goal of the present meta-analysis was to examine (a) the relationship between captioned viewing and incidental vocabulary learning and (b) what variables related to learners, treatment, methodology,…

Shadowing is the act of vocalizing the speech one is listening to as simultaneously as possible. The primary function of shadowing is learners' listening skill and pronunciation skill development. Despite the importance of second language (L2) listening skills, this pedagogical technique has not received focal attention in the field. In this…

While extensive research has explored Second Language Vocabulary Acquisition (SLVA) acquisition, there has been a lack of comprehensive bibliometric analysis on this topic. This study addresses this gap by investigating research trends and collaboration networks in SLVA over the past 24 years. Publications on SLVA were retrieved and analysed using…

In this study, we assessed metacognition in nonnative language speech perception and production. Spanish novice learners of French identified and produced the French vowel contrast /ø/--/oe/ and, on each trial, rated their confidence in their responses. Participants' confidence in perception predicted their identification accuracy, suggesting that…

This mixed-methods case study investigates learner engagement during pair work, focusing on four key aspects--behavioral, cognitive, emotional, and social engagement--and how these relate to task performance. The study included 60 university students (34 females, 26 males) learning English as a second language, who collaborated in pairs on a…

The present study investigates the impact of bidialectalism on L2 production, focusing on the role of dialect modes. Shanghai-Mandarin Chinese bidialectal speakers were recruited to produce second language (L2) English vowels under the influence of either Shanghai or Mandarin Chinese mode. Results showed that in the Shanghai mode, participants'…

This project studies how Spanish-Catalan early bilinguals use language learning strategies (LLS) differently depending on their order of language acquisition when they are learning French as an L4. Considering that the use of LLS has been pointed out as a sign of successful language learning, the study inquires whether being a simultaneous…

The perception of the teacher as the authority in the classroom is deep-rooted in education yet this notion seems to contradict the fundamental values of democratic education. Schools grant teachers an abundance of authority and decision-making power. The pedagogical implications of how teachers use this power in the classroom are not…

The present study complemented the extant second language (L2) Age of Acquisition (AoA) normative database by providing over 3500 English L2 words on objective AoA and over 2600 English L2 words on subjective AoA. The correlation between the objective and subjective L2 AoA confirmed the validity of the present database. The objective L2 AoA was…

While studies of contextualized game-based language learning (CGBLL) have to date gained a growing scholarly interest, there is still a lack of systematic review synthesizing its research trends regarding theoretical foundations, learning contexts, research foci and findings. To address the gap, this study collected data from the Web of Science…

Researchers, parents, and policymakers from previous generations have recently expressed concern about the inevitable exposure of youngsters to digital media and its potentially detrimental effects on their development. Private speech is the overt audible self-talk people produce when engaged with challenging problem-solving tasks and is believed…

This study investigates feature acquisition and feature reassembly associated with Clitic Left Dislocation (CLLD). The article compares the acquisition of CLLD in second language (L2) Italian to L2 Romanian to examine effects of first language (L1) transfer, construction frequency and the type of interface involved (external vs. internal…
