Bayesian Statistics
Over the past two decades, advances in computational power have facilitated the use of complex statistical modeling in academic research. As a result, sophisticated analytic strategies, such as multilevel modeling and structural equation modeling, are becoming commonplace, and computationally costly procedures, like Bayesian data analysis, have moved to the forefront. In particular, the use of Bayesian methods is gaining ground in the field of ap…
A tutorial on generalised additive mixed effects models for bilingualism research
While recent years have seen a shift towards random effects modelling, particularly in areas of linguistics in which nested structure is the norm (e.g., trial repetitions nested within participants), an over-reliance on standard linear modelling prevails, particularly in the cases of dynamic phenomena that may not constitute a linear relationship, e.g., vowel trajectories, pitch contours, acquisition processes, etc. Generalised Additive (Mixed) M…
Opening open science to all: Demystifying reproducibility and transparency practices in linguistic research
In recent years, numerous fields of research have seen a push for increased reproducibility and transparency. As a result, specific transparency practices have emerged, such as open access publishing, preregistration, sharing data, analyses, and code, performing study replications, and declaring positionality and conflicts of interest. While many agree that open science practices represent a positive step forward in improving scientific rigor, th…
Unraveling the Complexities of Second Language Lexical Stress Processing: The Impact of First Language Transfer, Second Language Proficiency, and Exposure
We investigated the role of cue weighting, second language (L2) proficiency, and L2 daily exposure in L2 learning of suprasegmentals different from the first language (L1), using eye-tracking. Spanish monolinguals, English-Spanish learners, and Mandarin-Spanish learners saw a paroxytone and an oxytone verb (e.g., FIRma-firMÓ "s/he signs-signed"), listened to a sentence containing one of the verbs, and chose the one that they heard. The three lang…
Interpreting experience and working memory effects on L1 and L2 morphological prediction
The human brain tries to process information as efficiently as possible through mechanisms like prediction. Native speakers predict linguistic information extensively, but L2 learners show variability. Interpreters use prediction while working and research shows that interpreting experience mediates L2 prediction. However, it is unclear whether advantages related to interpreting are due to higher working memory (WM) capacity, a typical characteri…
Conceptually Cued Perceptual Categorization in Adult L2 Learners
Previous studies attest that early bilinguals can modify their perceptual identification according to the fine-grained phonetic detail of the language they believe they are hearing. Following Gonzales et al. (2019), we replicate the double phonemic boundary effect in late learners (LBs) using conceptual-based cueing. We administered a forced choice identification task to 169 native English adult learners of Spanish in two sessions. In both sessio…
Interlingual Interactions Elicit Performance Mismatches Not "Compromise" Categories in Early Bilinguals: Evidence from Meta-Analysis and Coronal Stops
Previous studies attest that some early bilinguals produce the sounds of their languages in a manner that is characterized as "compromise" with regard to monolingual speakers. The present study uses meta-analytic techniques and coronal stop data from early bilinguals in order to assess this claim. The goal was to evaluate the cumulative evidence for "compromise" voice-onset time (VOT) in the speech of early bilinguals by providing a comprehensive…
Phonetic Category Formation is Perceptually Driven During the Early Stages of Adult L2 Development
Research on the acquisition of L2 phonology in sequential language learners has stressed the importance of language use and input as a means to accurate production and perception; however, the two constructs are difficult to evaluate and control. This study focuses on the role of language use during the initial stages of development of phonetic categories related to stop voicing and analyzes the relationship between production and perception. Nat…
The Longitudinal Development of Fine-Phonetic Detail: Stop Production in a Domestic Immersion Program
This study explored the initial stages of adult second language (L2) learning with a special focus on the acquisition of the target language sound system. The aim was to analyze the longitudinal development of Spanish stop voicing contrasts in an immersion learning context. Native English-speaking late learners of Spanish provided production data for Spanish stops on a weekly basis throughout a domestic immersion program. The data were analyzed u…
Perceptual categorization and bilingual language modes: Assessing the double phonemic boundary in early and late bilinguals
Language choice and accommodation: Casual encounters in San Ysidro and Nogales
The present study investigates language choice in two bilingual speech communities in the United States: Nogales, AZ and San Ysidro, CA. Ethnically distinct fieldworkers approached members of these two communities under the guise of being lost tourists in order to engage in casual speech encounters. It was found that language choice varied between the two communities, with participants of the San Ysidro community more likely to engage in codeswit…
Production and perception of the English /æ/–/ɑ/ contrast in switched-dominance speakers
This study investigates how fluent second-language (L2) learners of English produce and perceive the /æ/–/ɑ/ vowel contrast of Southwestern American English. Two learner groups are examined: (1) early, proficient English speakers who were raised by Spanish-speaking families but who became dominant in English during childhood and, as adults, lack communicative abilities in Spanish, and (2) Spanish-speaking late learners of English who continue to …
