The acquisition of communicative competence in second and foreign languages requires the incorporation of verbal and non-verbal elements. Notwithstanding, few studies have performed empirical research into the acquisition of non-verbal signs. This research studies the learning of emblematic gestures for students of Spanish in the USA using an…

Recent studies in the second language acquisition of negation have focused on polarity items and their licensing contexts. Although several studies show a correlation between higher degrees of second language (L2) proficiency and the acquisition of the target L2 structures, less attention has been given to the relation between the acquisition of…

This study investigates the use of metacognitive strategies by young emergent multilingual students in a translanguaging pedagogy scenario. From a multilingual perspective, we understand metacognition as a broader concept that refers to the learning or thinking processes that encapsulate metalinguistic and crosslinguistic awareness. We focus on…

The delayed acquisition of Spanish "ser" and "estar" is generally understood as rooted in the cognitive demands imposed by the integration of semantic-pragmatic and world-knowledge factors associated with their lexical meanings. Here we ask (1) what is the nature of this language world-knowledge integration? and (2) what is the…

The purpose of this study was to investigate sub-lexical segmentation in Spanish-speaking children based on the perception of regular syllables (pseudomorphemes), as well as their association with a visual referent. Both of these skills are the precursors to learning morphology for language acquisition. Twenty-three 12-month-old children…

Purpose: Though the frequency of gesture use by infants has been related to the development of different language abilities in the initial stages of language acquisition, less is known about whether this frequency (or "gesture rate") continues to correlate with language measures in later stages of language acquisition, or whether the…

Verbal morphology has been identified as a particularly vulnerable domain for adult heritage speakers (HSs) of Spanish, especially when it involves the selection of subjunctive mood. A minimal amount is known, however, about the potential effects of the variability associated with these forms on the acquisition of related epiphenomena, such as the…

This dissertation centers on the study of Kaqchikel word associations and the social variation that exists within them. Theoretical and methodological considerations for this project stem from the fields of psycholinguistics, variationist sociolinguistics, and cognitive linguistics. Together, these form an approach that fits within a blossoming…

Many second language (L2) learners participate in study abroad (SA) experiences believing their choice will be synonymous with increased interaction in the L2, from which enhanced linguistic gains will ensue. Nonetheless, one open question is whether SA participants actually engage in sustained L2 interaction while they are abroad. This paper…

Experience with a visual-spatial language may influence certain cognitive processes (Keehner and Gathercole 2007). Spatial ability is an important cognitive skill (Linn and Petersen 1985). Some research has found that deaf signers outperform hearing nonsigners on certain spatial tasks (e.g., Emmorey, Kosslyn, and Bellugi 1993) and that hearing…

Despite the extensive research on bilingual development, our understanding of how lexical competition unfolds in the bilingual mind remains limited. Previous studies have predominantly focused on crosslinguistic competition, neglecting the examination of the competition process within each language and the influence of diverse bilingual…

Language can alter our mental conceptions of space, time, and categories. While there is compelling evidence that thought can be shaped by syntactic, morphological, and lexical features of a language, less is known about the impact of phonology on thought. This dissertation uses novel objects (alien cartoon figures) and pseudoword names in three…

Previous literature has shown that voicing contrast is a difficult feature for Chinese-English emergent bilingual learners of L3 Spanish (Bravo Diaz, 2020; Chen, 2007; Zhang, 2022). The production of voicing contrast in stops has been broadly investigated in second and third language studies (e.g., Zampini, 1998; Llama, 2010; Wrembel, 2014), but…

This dissertation analyzes the production and perception of lexical stress in trilinguals' first, second, and third languages (L1, L2, and L3) to evaluate how the cue-weighting transfer hypothesis applies to L3 acquisition. According to this hypothesis, acoustic cues to stress have different weights across languages, and results from both…

Recent research on advanced theory of mind (ToM) has questioned the extent to which existing ToM measures capture a single construct, particularly for groups understudied in developmental research. The present study examined the factor structure of one of the most commonly used advanced ToM measures, the Strange Stories task, in samples of low-…
