This study tests the theoretical predictions regarding effects of increasing task complexity (Robinson, 2001a, 2001b, 2007, 2010; Robinson & Gilabert, 2007) for second language (L2) pronunciation. Specifically, we examine whether more complex tasks (a) lead to greater incidence of pronunciation-focused language-related episodes (LREs) and (b)…

In this study, verb placement with respect to negation is investigated in elicited production and elicited sentence imitation data collected with child second language (L2) learners of German. These data are compared to published data from adult L2 learners, which were collected with the same elicitation materials and were re-analysed for the…

Correct counting respects the stable order principle whereby the count terms are recited in a fixed order every time. The 4 experiments reported here tested whether precounting infants recognize and prefer correct stable-ordered counting. The authors introduced a novel preference paradigm in which infants could freely press two buttons to activate…

Research on second language (L2) grammar in task-based language learning has yielded inconsistent results regarding the effects of task-complexity, prompting calls for more nuanced analyses of L2 development and task performance. The present cross-sectional study contributes to this discussion by comparing the performance of 245 learners of German…

This study investigated the effect of formulaic language on L2 learners' ability to decode words in listening texts. One possibility was that formulas would facilitate listening by reducing the need to process every word of the sequences. However, a contrasting possibility was that the commonly reduced nature of formulaic words would hinder…

The present study sets out to examine whether and how task structure affects the number and type of vague expressions used by a group of higher intermediate EFL learners. The participants were 50 Iranian EFL learners from 6 intact classes, all native speakers of Persian with limited opportunity to communicate with native speakers of English, and…

The present study explores the independent and interactive effects of task complexity and task modality on linguistic dimensions of second language (L2) performance and investigates how these effects are modulated by individual differences in working memory capacity. Thirty-two intermediate learners of L2 Spanish completed less and more complex…

This study examined relationships between language learning motivation and the longitudinal development of second language (L2) pronunciation. Twenty-six English-speaking learners of Spanish recorded a simplified picture description task 5 times over a year-long period spanning their 2nd, 3rd, and 4th semesters of Spanish language instruction.…

This study tests the hypothesis that late first-language English / second-language Spanish learners (L1 English / L2 Spanish learners) acquire spirantization in stages according to the prosodic hierarchy (Zampini, 1997, 1998). In Spanish, voiced stops [b d g] surface after a pause or nasal stop, and continuants [ß? ð? ??] surface postvocalically,…

This study investigated the mode of directness of requests and refusals and the background variables that explain this production in two trilingual populations in Israel (i.e. native speakers of Arabic for whom English is an L3, and Hebrew, an L2, and native speakers of Hebrew for whom English is an L2 and another language is their L3). Data were…

A significant body of theoretically motivated research has addressed the role of Universal Grammar (UG) in the nonnative acquisition of morphosyntax and properties of the syntax-semantics interface, but very little research has addressed the role of phonological principles of UG in nonnative language acquisition. Turkish has a regular and…

Is there an ideal time window for language acquisition after which nativelike representation and processing are unattainable? Although this question has been heavily debated, no consensus has been reached. Here, we present evidence for a sensitive period in language development and show that it is specific to grammar. We conducted a masked priming…

Accurate metacognitive monitoring of one's own knowledge or performance is a precondition for self-regulated learning; monitoring informs metacognitive control, which in turn affects task outcomes. Studies of monitoring accuracy and its connection to knowledge and performance are common in psychology and educational research but rare in instructed…

This study aimed at examining the possible effects of teacher motivational practices and student demotivation on the way Iranian English as a Foreign Language (EFL) learners produce request and refusal speech acts. Subsequently, four instruments were selected and administered to the participants under scrutiny. They were: (a) a Quick Placement…

This study examined the effectiveness of explicit instruction and feedback, focusing on degrees of prior knowledge of the personal "a" in intermediate level second language (L2) Spanish. On the pretest, participants (n = 58) completed grammaticality judgment and picture description tasks, which found that learners had different degrees…
