In Krashen's theory of second-language acquisition he claims that there is distinction between language acquisition and language learning, a distinction which other second-language acquisition researchers have called "perhaps the most important conceptualization" in the field and which has made possible the most productive models of SLA.…

This paper supports the view that language instruction should be evidence and principle-based. Key facts about second language acquisition will be presented highlighting the main implications for language instruction. A principled and evidence-based approach to language instruction is one which takes into consideration the following: (i) a clear…

In contexts of first language (L1) acquisition, prediction and adaptation are often viewed as fundamental to the learning process (Rabagliati et al., 2016). One mechanism that has been proposed to specifically account for such adaptive behavior is error-based implicit learning (e.g., Chang et al., 2006). According to this account, speakers…

The acquisition of voice in Greek remains understudied, especially in heritage populations. Voice in Greek poses a challenging acquisition task for children due to its syncretism, marking various verb classes as well as passives. The present study explores the acquisition of anticausatives, reflexives, and passives in 6-to-8-year-old monolingual…

In this paper, the researcher aims at investigating and revisiting the impact of Krashen's input hypothesis on L2 output. Based on Krashen's theories, the researcher proposes the homogeneity hypothesis as an extension to the input hypothesis. Homogeneity hypothesis states that the linguistic input given to L2 learners should be not only…

Second language acquisition has been observed to be variable in its outcome such that, unlike native speakers, all second language learners do not achieve total success. Second language acquisition is made of macro and micro processes. External and internal (e.g., age, individual differences) factors are assumed to affect language processing in…

This dissertation investigates how English-speaking second language (L2) learners of Mandarin perceive, process and learn Mandarin lexical tones. While most languages use modulations in pitch (intonation) to convey meanings at the phrasal and sentential levels, a number of languages, including Mandarin, also use suprasegmental features such as…

Despite a growing body of research on English-medium instruction (EMI), little is known about how actual EMI lecturers' language practices support L2 learning, specifically key psycholinguistic processes such as learner comprehension and output. This paper presents a classroom-centred study of the L2 learning opportunities found in the EMI…

Listening comprehension is a real-time process, yet very little is known about the variables affecting real-time second language (L2) listening. The present study aimed at investigating the effects of syntactic complexity and word frequency on L2 listening. Furthermore, the role of the listener's working memory capacity in listening comprehension…

This study examines whether semantic relatedness facilitates or impedes the acquisition of English collocations by conducting two experiments respectively on Chinese undergraduates. Each experiment was composed of a reading session, a productive test, and a receptive test. Experiment 1 began with the reading session of 28 paired-up words and their…

This study investigated whether Chinese--Korean bilinguals can use structure-based information to interpret Korean sentences containing floating numeral quantifiers during online processing. A numeral quantifier in Korean can be stranded from its modified noun through scrambling as long as the quantifier forms a constituent with the noun. For…

We examined the role of modality in learning second language (L2) grammar and forming implicit (unconscious) and explicit (conscious) knowledge. To this end, we isolated the effects of the physical medium of input (i.e., aural or visual) from those of the presentation method (i.e., word-by-word or simultaneous). We also explored the role of test…

Integrated test tasks, such as listening-to-speak or reading-to-write, are increasingly used in second language assessment despite relatively limited empirical insights into what they assess. Most research on integrated tasks has primarily focused on the productive skills involved; studies exploring the receptive skills mostly investigated tasks…

This study of second language idiom acquisition investigates the interaction of two factors, the L1 effect and the effect of supportive context in the L2 input, when both are available to learners. An experiment consisting of a pretest, a computer-assisted instructional treatment session and a posttest employed three idiom types that differed in…

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…
