Second language (L2) grammar learning is difficult. Two frameworks--the psycholinguistic lexical bottleneck hypothesis and the neurocognitive declarative/procedural model--predict that faster L2 lexical processing should facilitate L2 incidental grammar learning. We tested these predictions in a pretest-posttest syntactic adaptation study of…

Learning language requires acquiring the grammatical categories of words in the language, but learning those categories requires understanding the role of words in the syntax. In this study, we examined how this chicken and egg problem is resolved by learners of an artificial language comprising nouns, verbs, adjectives, and case markers following…

We test the comprehension of transitive sentences in very young learners of Mandarin Chinese using a combination of the weird word order paradigm with the use of pseudo-verbs and the preferential looking paradigm, replicating the experiment of Franck et al. (2013) on French. Seventeen typically-developing Mandarin infants (mean age: 17.4 months)…

Although there is a broad consensus that both the procedural and declarative memory systems play a crucial role in language learning, use, and knowledge, the mapping between linguistic types and memory structures remains underspecified: by default, a dual-route mapping of language systems to memory systems is assumed, with declarative memory…

Growing up in the digital era, young children are exposed to numerous educational applications and programs, some with well-designed curricula and others focused more on entertainment or game-like qualities. With the increasing popularity of mobile language-learning applications among young children, this dissertation raises a crucial question: do…

The number of learners seeking to acquire an L2 by means of apps is ever-increasing. This study examined the effectiveness of using the app "Mondly" for the acquisition of L2 English vocabulary while accounting for differences in the acquisition of receptive and productive aspects of word knowledge. Twelve Danish young learners (aged…

Although retrieval of lexical forms is a prerequisite for language production, research of L2 vocabulary learning has focused much more on meanings and form-meaning mappings than on development of detailed, accessible mental representations of forms. This is particularly true with respect to multi-word items (MWIs). We report an experimental study…

Language can alter our mental conceptions of space, time, and categories. While there is compelling evidence that thought can be shaped by syntactic, morphological, and lexical features of a language, less is known about the impact of phonology on thought. This dissertation uses novel objects (alien cartoon figures) and pseudoword names in three…

Over the past two decades, the Involvement Load Hypothesis (ILH) has become a popular buzzword in the field of Second Language Acquisition (SLA). Although applications of the ILH can improve students' learning of productive vocabulary, this effect appears to be transitory. Students' learning of productive vocabulary often fades over time, as shown…

Twenty participants who were deaf and 20 chronological age-matched participants with typical hearing (TH) (mean age: 12 years) were asked to judge the correctness of written sentences with or without a grammatically incongruent word while their eye movements were registered. TH participants outperformed deaf participants in grammaticality judgment…

The use of machine translation (MT) in the academic context has increased in recent years. Hence, language teachers have found it difficult to ignore MT, which has led to some concerns. Among the concerns, its accuracy has become a major factor that shapes language teachers' pedagogical decision to use MT in their language classrooms. Despite the…

Generalization is the ability to apply regularities to novel instances, for example, correctly guessing that the plural for the novel English word 'wug' should be 'wugs'. Early language learners make overgeneralization errors like 'mouses', applying regularities beyond their attested uses. Theories concerned with the question of how learners learn…

This study combines explicit (pen-and-paper) and sensitive (time-pressured) measures to gauge the impact of three instructional interventions (contextualized input with meaning-focused activities, contextualized input with word-focused activities, and decontextualized input with word-focused exercises) on the learning of 20 L2 French target verbs.…

Vulnerability of morphosyntactic production, including grammatical aspect, has been identified in at least some children with autism spectrum disorder (ASD) exposed to typologically different languages. However, Tovar et al. (2015) found strengths in comprehending grammatical aspect in English-exposed children with ASD, suggesting that the…

Lexical knowledge is complex, multidimensional, and difficult to pin down to a set of defined components. The development, organization, and use of lexical knowledge in the first and additional languages are studied in a number of neighbouring disciplines beyond second language acquisition and applied linguistics, including psycholinguistics,…
