To respond to recent calls for examining oral fluency from a broader social and communicative perspective, the current study aimed at investigating the effects of task communicative function on second language (L2) and first language (L1) speakers' fluency. Designing tasks that represent three different communicative functions (congratulations,…

This study examines a 30-item Spanish elicited imitation task (EIT) as a measure of global language proficiency for heritage language (HL) learners of Spanish. Results from Rasch modeling suggest that, while EIT scores demonstrated excellent reliability, the ability of much of the HL sample far exceeded the difficulty of the items. Differential…

This study examines the impact of instructor-led (IL) versus self-access (SA) web-based pragmatic instruction on novice second language learners' (n = 28) awareness and oral production of Spanish apologies. Two sections of a second-semester Spanish course were assigned to either the IL or the SA group. The web-based resource "Dancing with…

In this single-case study with a quasi-experimental design, we set out to examine the role of two input-based features of the language learning app Duolingo on learners' development of implicit and explicit second language (L2) knowledge. We investigated the effect of Duolingo's Stories feature and Podcast feature on two Spanish-L2 learners'…

The system of second person singular forms of address (2PS) in Medellín, Colombia is tripartite consisting of "tú, vos," and "usted," while also including the existence of a dual "usted." The current study compares usage of the intimate "usted" versus the distant "usted" with data from an oral…

Over past decades, there has been a paradigm shift in WL instruction, moving away from traditional, grammar-based programs and toward instruction that promotes student proficiency in the target language. Despite this growing attention to proficiency-based instruction, few studies have investigated the relationship between proficiency-based…

Studying the oral language growth of Spanish-speaking preschoolers in the United States is increasingly important given the critical role early language development plays in reading outcomes. In this article, we report on the Spanish and English growth trajectories observed in 124 bilingual preschoolers collected over 2 years in 36 classrooms…

This sociophonetic study examines affricate variation through a continuous lens using diachronic data from Caracas Spanish. We investigate the relationship between frication and occlusion period duration in affricate segments across two steps. First, we present a phonetic characterization of the dependent variable and its variants. Second, we…

Research has indicated that lexical richness is an important indicator of second language (L2) proficiency. However, most research has examined written, cross-sectional English L2 corpora and does not necessarily indicate how spoken lexical use develops over time or whether observed trends are stable across L2s. This study adds to previous…

The ACTFL Oral Proficiency Interview--computer (OPIc) employs a self-assessment instrument to determine the nature of the speaking prompts to which the test taker will respond and, thus the difficulty of the test. Grounded in research demonstrating varying levels of accuracy in self-assessment among language learners, this study examines the…

This systematic review aims to explore how task complexity and task sequencing affect the complexity, accuracy, and fluency (CAF) of second language performance. Through an analysis of studies conducted between 2012 and 2021, this review investigates the characteristics of the studies, operationalisation of task complexity, measurements of CAF,…

Laboratory observations are a mainstay of language development research, but transcription is costly. We test whether speech recognition technology originally designed for day-long contexts can be usefully applied to this use-case. We compared automated adult word and child vocalization counts from Language Environment Analysis (LENA[TM]) to those…

Purpose: The purpose of this study was to identify and describe latent dual language profiles in a large sample of school-age Spanish-English bilingual children designated as English learners (ELs) by their school district. Method: Data for this study include 847 Spanish-speaking ELs from kindergarten to third grade. Spanish and English narrative…

This aptitude-treatment interaction study investigated the extent to which explicit and implicit cognitive abilities are differentially related to learning outcomes under two corrective feedback conditions. One hundred and thirteen intermediate English learners of Spanish were randomly assigned to an implicit feedback (recast), explicit feedback…

We examined the relations of language skills (vocabulary, listening comprehension, and oral retell), transcription skills (spelling and handwriting fluency), and domain-general cognitions/executive functions (working memory and attentional control) to writing quality for English-Spanish emergent bilingual children in Grade 1. Data were from a…
