This paper presents a set of guidelines for reporting on five types of quantitative data issues: (1) Descriptive statistics, (2) Effect sizes and confidence intervals, (3) Instrument reliability, (4) Visual displays of data, and (5) Raw data. Our recommendations are derived mainly from various professional sources related to L2 research but…

This study investigated the effects of task complexity on child learners' second language (L2) gains, the relationship between aptitude and L2 development, and the extent to which task complexity influences this relationship when recasts are provided. Sixty child EFL learners were assigned to two experimental groups. During the treatment, one…

The effect of age of acquisition on ultimate attainment in second language learning has been a controversial topic for years. After providing a very brief overview of the ideas that are at the core of the controversy, I discuss the two main reasons why these issues are so controversial: conceptual misunderstandings and methodological difficulties.…

This study investigates acquisition of second language (L2) vocabulary from reading a connected authentic text. Advanced and upper-intermediate L2 (English) participants read a long expository text for general understanding, with embedded critical vocabulary items (pseudowords). Explicit knowledge of the critical items was examined using a meaning…

When native speakers judge the acceptability of novel sentences, they appear to implicitly take competing formulations into account, judging novel sentences with a readily available alternative formulation to be less acceptable than novel sentences with no competing alternative. Moreover, novel sentences with a competing alternative are more…

This study compared the lexical-semantic organization skills of bilingually developing deaf children in American Sign Language (ASL) and English with those of a monolingual hearing group. A repeated meaning-association paradigm was used to assess retrieval of semantic relations in deaf 6-10-year-olds exposed to ASL from birth by their deaf…

I will propose a tentative framework of how words in two languages could be organized in the cerebral cortex based on neural assembly theory, according to which neurons that fire synchronously are bound into large-scale distributed functional units (assemblies), which represent a mental event as a whole ("gestalt"). For language this…

The tendency of intermediate and advanced second language speakers to underuse pronouns and zero anaphora has been characterized as a developmental stage of overexplicitness, yet little consideration has been given to whether learners create sufficient contexts for their use. This study analyzed references across eight degrees of accessibility,…

The loss of a childhood language, especially in adoptees, has attracted scholars' attention in the past, but a search for any memory traces has yielded conflicting results. In a psycholinguistic tradition known as the savings paradigm, a learn-and-relearn technique is employed to examine whether the relearning of lexical items once known, often in…

Research synthesis and meta-analysis provide a pathway to bring together findings in a given domain with greater systematicity, objectivity, and transparency than traditional reviews. The same techniques and corresponding benefits can be and have been applied to examine methodological practices in second language (L2) research (e.g., Plonsky,…

This study aimed to advance research on first and second language future-time expression in Spanish and to demonstrate the strengths of combining functionalist, concept-oriented approaches (e.g., Andersen, 1984; Bardovi-Harlig, 2000; Shirai, 1995; von Stutterheim & Klein, 1987) with variationist approaches. The study targeted 140 participants…

Language aptitude has been hypothesized as a factor that can compensate for postcritical period effects in language learning capacity. However, previous research has primarily focused on instructed contexts and rarely on acquisition-rich learning environments where there is a potential for massive amounts of input. In addition, the studies…

The present research explores working memory (WM) development in monolingual as well as emergent bilingual children immersed in an L2 at school. Evidence from recent years suggests that bilingualism may boost domain-general executive control, but impair nonexecutive linguistic processing. Both are relevant for verbal WM, but different paradigms…

The effects of production and listening training on the subsequent comprehension of foreign-accented speech were investigated in a training-test paradigm. During training, German nonnative (L2) and English native (L1) participants listened to a story spoken by a German speaker who replaced all English /?/s with /t/ (e.g., *"teft" for…

This study reports on the conceptualization of a new construct targeting the cross-disciplinary academic language skills most relevant to school reading comprehension, targeting the validation of the Core Academic Language Skills (CALS) Instrument, a novel assessment tool which measures this construct. Participants included Grade 4-8 monolingual…
