Theories of embodied cognition describe language acquisition and representation as dependent on sensorimotor experiences that are collected during learning. Whereas native language words are typically acquired through sensorimotor experiences, foreign language (L2) words are often learned by reading, listening or repeating bilingual word lists.…

The relationship between language switching and task switching has been well studied in bilingualism literature. This study employs novel experiments involving magnitude-parity switching and transparency-orientation switching and compares the costs associated with these two types of task switching with language switching. Switching costs and the…

Few studies have considered bilingualism's impact on cognitive development within the sociolinguistic and cultural context of the immigrant communities where bilingualism is commonly practiced. In the United States, many Mexican-origin bilingual youth practice their bilingual skills by "brokering" (i.e. translating/interpreting between…

The present study compared bilingualism with bidialectalism in their respective impact on executive control, using a short-term language switching training paradigm for participants who were both bidialectals (Shanghainese-Mandarin Chinese) and bilinguals (Chinese-English). Twenty participants were assigned to a control group where no language…

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…

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…

An aim of research on bilingualism is to understand how the brain adapts to the use of more than one language. Although several important discoveries and insights about the consequences of bilingualism have been generated over the last several decades, concerns about replicability have narrowed the scope of inquiry and discussion to the…

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…

This dissertation uses the Conceptual Blending Hypothesis from the socio-cognitive method presented and refined by Kecskes (2002, 2004, 2007, 2010, 2020) to explain how the lexical choice of bilinguals differs across sociocultural situations. Quantitative (lexical density, lexical diversity, and lexical sophistication) and qualitative (lexical…

Language switch costs have been explored less in receptive tasks than in productive tasks, and previous studies have produced mixed findings with regard to switch cost symmetry and the relationship of switch costs to executive function. To address these unresolved gaps, one hundred Chinese-English bilingual adults completed a bilingual lexical…

This dissertation research examines the acquisition of second language vowels. For second language learners, learning a new languages' sound inventory, particularly its vowels, presents a challenge perceptually and in terms of production. Incorrectly perceiving and producing sounds in a second language results in a foreign accent in many adult…

The current research examined how Arabic diglossia affects verbal learning memory. Thirty native Arab college students were tested using auditory verbal memory test that was adapted according to the Rey Auditory Verbal Learning Test and developed in three versions: Pure spoken language version (SL), pure standard language version (SA), and…

This study investigated whether the effect of exposure to code-switching on bilingual children's language performance varied depending on verbal working memory (WM). A large sample of school-aged Spanish-English bilingual children (N = 174, Mage = 7.78) was recruited, and children were administered language measures in English and Spanish. The…

Bilingualism is associated with lifelong cognitive benefits that correlate with facilitated achievements in subsequent language learning. Second language (L2) instruction as well can promote the development of cognitive abilities involved in language learning, and among these, L2 input processing. Crucial to L2 acquisition, input processing is the…

This special issue on language diversity and bilingual processing is based on papers presented at the "Exploratory Workshop on Speaking, Thinking and Gesturing in Two Languages," at the University of Reading, UK, in September 2012, sponsored by the European Science Foundation (IM/SCH/EW11-145). The workshop brought together a…
