This commentary discusses the recent keynote article by Westergaard (2021), which is an interesting contribution to the field of language acquisition and multilingualism, especially because it attempts to provide a wider perspective by embracing first, second and third language acquisition. I address major claims put forward by Westergaard, to…

Recent research suggests that psychotypology may be one of the main factors determining L3 acquisition and use, especially so in the early stages. However, the existence and nature of multilingual learners' perception of language proximity have often only been assumed rather than measured, and rarely addressed with respect to the increasingly…

Although English and German are both Germanic languages, due to various historical changes, many of their cognates are no longer easily recognizable. This study examined whether knowledge of language history can be beneficial to learners when learning English-German cognates. Thirty-five English-speaking second language (L2) learners of…

Although the mapping between form and meaning is often regarded as arbitrary, there are in fact well-known constraints on words which are the result of functional pressures associated with language use and its acquisition. In particular, languages have been shown to encode meaning distinctions in their sound properties, which may be important for…

This dissertation investigates a typologically rare linguistic phenomenon found in Irish from three different perspectives: how it challenges phonological theory, how it is used by contemporary speakers, and how its written representation affects its acquisition. Initial consonant mutation (ICM), as it appears in the Celtic languages, is known to…

We investigated age-related decline in adult learning of Dutch as an additional language (Ln) in speaking, writing, listening, and reading proficiency test scores for 56,024 adult immigrants with 50 L1s who came to the Netherlands for study or work. Performance for all four language skills turned out to decline monotonically after an age of…

We review cognitive-linguistic approaches to conveying meaning, sound, and orthographic information across scripts in order to highlight the impact of variability in written and spoken language on learning to read and to write words. With examples of word recognition and word writing from different scripts, including Chinese, Arabic, Persian, and…

This study investigated the influence of phonological word representations from both first language (L1) and second language (L2) on third language (L3) lexical learning in L1-dominant Spanish-English bilinguals. More specifically, we used event-related potentials (ERPs) to determine whether L1 Spanish and L2 English phonology modulates…

This paper investigates the phonology of L2 speech and its impact on intelligibility in English as a Lingua Franca (ELF) contexts. Many studies have considered speaker-related characteristics, such as speech styles and pronunciation features, that influence the intelligibility of L2 speech for both nonnative speakers (NNS) and native speakers…

To avoid potential miscommunication resulting from structural ambiguity, speakers and listeners often rely on differences in prosodic realization. For instance, the sentence "Jennifer blackmailed the boss of the clerk [who was dishonest"][subscript RC'] is realized with different prosody depending on the attachment of the relative clause…

The parasitic model proposes that novel words in L3 learning will build parasitic connections to already learned words that share orthographic or phonological similarities. This accounts for little in terms of the connections between words that share very few similarities. The present study explored the parasitic connections of L3 word concepts to…

The syllable is a natural unit of organization in spoken language. Strong cross-linguistic tendencies in syllable size and shape are often explained in terms of a universal preference for the CV structure, a type which is also privileged in abstract models of the syllable. Syllable patterns such as those found in Itelmen "qsa?txt??"…

While tonal systems have typically been classified as "pitch accent" or "true tonal", there is growing evidence that systems instead have a variety of features which vary across languages, rather than falling into discrete categories. These category labels have been used widely in literature about the languages of New Guinea,…

Past experimental studies of corrective feedback (CF) have isolated factors like grammatical complexity, learner proficiency, and L1 one by one, carefully designing experiments that eliminate the influence of "extraneous" factors. Because each factor is actually codependent, more holistic study is needed. Eleven studies, all of which had…

A great deal of the research on cross-linguistic phonetic influence demonstrates that a speaker's knowledge of their first language (L1) significantly affects their ability to perceive and produce sounds in any other language. While current studies show that cross-linguistic transfer occurs at the L3 level, some research suggests that properties…
