Cognitive flexibility (switching) and control (inhibition) are among widely accepted cognitive advantages of bilingualism. Switch Cost (SC), i.e., the time difference to complete a switch versus non-switch task, is a construct for measuring the switching ability. The need to control the interference and switching between one's languages leads to…

Previous studies on spoken word production have shown that native English speakers used phoneme-sized units (e.g., a word-initial phoneme, C) to produce English words, and native Mandarin Chinese speakers employed syllable-sized units (e.g., a word-initial consonant and vowel, CV) as phonological encoding units in Chinese. With spoken word…

In Germanic and Slavic languages, the Verb is the most extensive grammatical item, which causes most of the troubles for second language learners. It has been noticed that Slavic L1 learners of English make mistakes in using verb forms due to the transfer of their L1 grammatical system (grammar concepts) onto the English language. The goal of the…

This research investigated avoidance behaviour, one of the strategies L2 learners may resort to because of L1-L2 differences, or the non-existence of L2 structures for L1 learners, i.e. the Avoidance Behaviour Hypothesis (Schachter 1974). However, based on the Factors of L2 Non-Avoidance Hypothesis (FNAH) (Thiamtawan & Pongpairoj, 2013, 2019),…

This study is primarily designed for investigating the tertiary students' perspectives on the writing difficulties of essays. This study was conducted in explanatory research in which quantitative and qualitative data were obtained from the web-based questionnaire and semi-structured interview, then analyzed separately. Twenty-one undergraduate…

This study aimed at the analysis of syntactic errors in translation done by both bilingual and monolingual EFL learners. Research on the subject of the study implied that there might be differences between monolinguals and bilingual learners of foreign languages. The gaps of studies on differences between monolinguals and bilingual's translations…

It has long been debated whether interpretation should be performed only from a foreign language to the mother tongue or whether it should be performed from the mother tongue to a foreign language. Those in favor of the foreign to native language direction posit that such directionality allows the interpreter to produce more natural target…

The learning process of English as a Foreign Language is a tricky challenge to face when it comes to deal with Spanish native speakers. Most of the time, people compare the structures and uses of both languages (the native and the target one), which causes an interference in the learning process and may result on failure or poorly achieved…

This article reports on an empirical study on the acquisition of Chinese imperfective markers ("zai," "-zhe[subscript P]" and "-zhe[subscript R]") by English-speaking learners at three proficiency levels. Compared to English, Chinese has a richer imperfective aspect in terms of markers (forms) and features (meanings).…

This study demonstrates how native and learner corpora can enhance modal verb treatment in English-as-a-foreign-language (EFL) textbooks used in mainland China. Data analysis compares modal verbs in the textbook and native corpus by referring to distributional features, semantic functions and co-occurring constructions; and the analysis of the…

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…

In phonetics research, language alternation--including code switching (speaker-initiated) and cued switching (researcher-prompted)--can be used as a tool to investigate various aspects of speech production and perception in bilingual or multilingual speakers (Bullock & Toribio, 2009a). Studies on the production of voice onset time (VOT) during…

This study investigated features of first language and cultural interference in Thai EFL learners' English paragraph writing on popular culture. Drawing from theoretical grounds of interlanguage, language interference, and rhetorical interference, the sample of 30 English paragraphs of Thai EFL undergraduate learners was examined quantitatively…

There has been a plethora of studies investigating the effect of semantic relatedness on second language (L2) word learning.However, most prior studies failed to control for the lexical properties of target words, which may be responsible for the mixed results yielded. This study, therefore, sets out to revisit this issue by controlling for L1…

Recent research conducted as part of the English Profile identified grammatical criterial features that are characteristic of each Common European Framework of Reference (CEFR) proficiency level. The extent to which these criterial features attest in English learners of various first language backgrounds call for an empirical examination. In this…
