This dissertation investigates how parametric variation of linguistic properties leads to similarities and differences in language processing across the levels of words, grammatical features, and sentences. For a truly generalizable theory of psycholinguistics, the languages surveyed should not be constrained to English (Garnham, 1994; Norcliffe…

A central concern of the cognitive science of language since its origins has been the concept of the linguistic system. Recent approaches to the system concept in language point to the exceedingly complex relations that hold between many kinds of interdependent systems, but it can be difficult to know how to proceed when "everything is…

This commentary discusses the recent keynote article in "Second Language Research" by Westergaard (2021), which extends the Micro-cue Model to second language (L2) and third language (L3) acquisition. The commentary comments on such questions as: What makes a given property easy or hard to acquire? How do learners determine similarity?…

This dissertation presents a series of case studies concerned with whether the signal in a given set of measurements that we take in the course of linguistic inquiry reflects grammatical competence or performance factors. We know that performance and competence do not always covary, yet it is not uncommon to assume that measurements that we take…

Understanding how native speakers acquire the phonological patterns in their language is a key task for the field of phonology. Numerous studies have suggested that phonological learning is a biased process: certain phonological patterns are easily accessed and learned by the speakers, while others show acquisition difficulties. These differences…

In this commentary, I suggest that it may be helpful to think about the formidable problem space that Westergaard's (2021) Linguistic Proximity Model seeks to address at the three levels of analysis that Marr (1982) famously proposed are needed to understand any complex cognitive system. I argue that at the computational level of analysis, where…

Different linguistic classifications of Spanish and Slovak make the differences between these two languages. The genetic criterion classifies languages, clustering them into language families, the largest among which is the Indoeuropean one. The typological criterion divides languages according to their grammatical structures. Meanwhile, Slovak is…

The main goal of this tutorial is to promote the study of children with developmental language disorder (DLD) across different languages of the world. The cumulative effect of these efforts is likely to be a set of more compelling and comprehensive theories of language learning difficulties and, possibly, of language acquisition in general.…

This dissertation seeks to answer three loosely-related questions regarding ergativity. First, what is the nature of the morphological phenomena known as ERG=GEN and ERG=POSS? After providing a thorough description with ample data from a wide range of sources, a typological survey of 40 ergative languages concludes that together, they are a fairly…

Many studies have explored the second language (L2) acquisition of relative clauses (RCs) and whether L2 speakers transfer a resumptive strategy from first language (L1) to L2. While evidence seems to suggest that there are significant L1-L2 differences in the processing of RCs, relatively little is known about the source of non-target-like L2…

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…

This paper applies the theories of linguistic distance and translanguaging to analyse the pedagogy of teaching vocabulary and grammar in English to Malay-English bilinguals who are struggling to read in English. More specifically the paper explores how the teacher tried to create cross-linguistic transfer and how the students display…

The Bottleneck Hypothesis argues that properties of inflectional morphology explain why second-language learners may face persistent difficulties in articulating meaning in target-language forms. In particular, the acquisition task proves even harder when first and second languages differ in the way they organize the mapping of functional features…

This study explores the source of transfer in third language (L3) English by two distinct groups of Catalan-Spanish bilinguals, simultaneous bilinguals and late bilinguals. Our study addresses two research questions: (1) Does transfer come from the first language (L1), the second language (L2), or both? and (2) Does age of acquisition of the L2…

This article investigates phenomena related to subject pronoun realization in the English interlanguage of Macedonian learners. Preliminary research indicates that learners tend to omit the subject pronoun in both referential and non-referential contexts. It can be presumed that such interlanguage features are due to crosslinguistic influence,…
