Unlike with the typically developing population, non-typically developing individuals, especially those with intellectual disabilities, have usually been recommended to learn and use only one language, despite perhaps coming from bilingual families or living in multilingual environments. This common practice, however, is not backed by empirical…

When teaching Mandarin Chinese classifiers, teachers usually ask students to memorize 'classifier + noun', phrases as collocations. Given that Mandarin Chinese has a vast and complicated system of classifiers, the rote memorization of 'classifier + noun' collocations is challenging and monotonous. Therefore, the present study aims to improve that…

The linguistic interdependence hypothesis posits the existence of language features common to different languages. This set of characteristics, known as Common Underlying Proficiency (CUP), is a powerful facilitating agent in second language acquisition. Fluid intelligence (Gf), on the other hand, is the construct that encompasses those cognitive…

This study examined whether the linguistic distance between the first (L1) and second (L2) language is a significant determinant of L2 writing skills of 292 adult immigrants from 39 different source countries, who were beginner learners of Spanish L2. Gender, age, length of residence in Spain, education level as a proxy for literacy skills in L1,…

This meta-synthesis study aims to reveal the types of bilingualism in Turkey by interpreting the quantitative data and findings obtained from studies on bilingualism types. In the light of the findings, 28 types of bilingualism and 5 classification criteria have been identified in the theses written on bilingualism in the "Turkish Higher…

Research on language and cognitive processes in bilinguals over the past few decades has underscored the activation of words in the first language (L1) during comprehension and production of the second language (L2) (e.g., Dijkstra, Van Jaarsveld, & Ten Brinke, 1998; Van Heuven, Dijkstra, & Grainger, 1998; Hermans, Bongaerts, De Bot, &…

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…

Over the past few years, many studies have examined the cognitive processes of students when translating texts from one language to another. However, little is known about the cognitive processes of Arab translators when translating texts from their heritage language into English. This study aims to track the cognitive processes of students as…

The current study examined the extent to which first language (L1) utterance fluency measures can predict second language (L2) fluency and how L2 proficiency moderates the relationship between L1 and L2 fluency. A total of 104 Japanese-speaking learners of English completed different argumentative speech tasks in their L1 and L2. Their speaking…

The linguistic relativity hypothesis has focused on the influence of grammar in language on speakers' cognition. Previous studies show that speakers of languages with grammatical number (e.g., English) are more aware of the number of objects. Additionally, recent studies reveal that bilinguals who speak languages with different grammatical…

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…

The present study tested whether the switch costs of production-based language switching tasks by trilinguals are due to competition from outside language schemas or from within language systems. We recruited 90 Tibetan-Chinese-English trilinguals in 10th grade in a Tibetan middle school in China to name digits and number words using different…

Research on first language (L1) attrition typically focuses on immigrant populations in their second language (L2) environment, yet we know comparably little about L1 attrition in the L1 setting. This study used two lexical tasks to test L1 attrition, a time-sensitive word decision task and a video retelling. Chinese teachers of English vs.…

When reading Chinese, skilled native readers regularly gain a preview benefit (PB) when the parafoveal word is orthographically or semantically related to the target word. Evidence shows that non-native, beginning Chinese readers can obtain an orthographic PB during Chinese reading, which indicates the parafoveal processing of low-level visual…

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…
