Embodied models of language comprehension assume that words become associated with sensorimotor experiences during word learning. Novel word learning paradigms may provide insight into embodied effects, but studies in this domain have yet to account for how concepts and information known in first language (L1) might influence the sensorimotor…

Toddlerhood is marked by advances in several lexico-semantic skills, including improvements in the size and structure of the lexicon and increased efficiency in lexical processing. This project seeks to delineate how early changes in vocabulary size and vocabulary structure support lexical processing (Experiment 1), and how these three skills…

Aural vocabulary knowledge (AVK) of high-frequency words is critical for second language listening comprehension. However, learners of English as a foreign language (EFL), despite considerable periods of language study, often do not have the AVK needed for basic communicative competence. A mixed methods approach is applied to determine whether…

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…

Although researchers argue that studying semantically related words simultaneously (semantic clustering) inhibits vocabulary acquisition, recent studies have yielded inconsistent results. This study examined the effects of semantic clustering while addressing the limitations of previous studies (e.g., confounding of semantic relatedness with other…

This study examines the proposition that second language learners tend to map second language (L2) lexical forms onto the existing semantic content of their first language (L1) translations rather than creating a separate semantic network for the second language. To test this, the participants (n=9) responded to three semantic judgement tasks. In…

This dissertation consists of three studies that investigate the extent to which speakers and listeners can and do plan ahead during production and comprehension. Study 1 investigates the attentional requirements of word selection. In two dual-task experiments, subjects categorized tones and then named pictures while word selection difficulty was…

It has been repeatedly argued among vocabulary researchers that semantically related words should not be taught simultaneously because they can interfere with each other. However, the question of what types of relatedness cause interference has rarely been examined carefully. In addition, there are disagreements among the past studies that have…

This paper mainly explores the impacts of presenting new words in semantically-related (SR) sets on vocabulary learning. 38 students from two classes of Grade 2 in Taiyuan Foreign Language School (Senior High School Section) participate in the whole process. The same vocabulary items unknown to all students are taught to them in 4 lessons. The…

The field of research in bilingualism and second language (L2) acquisition has yielded overwhelming evidence that acquiring a second language later in life will result in less accurate production and perception of consonants and vowels in the second language. These effects, in part, are a result of interference from the already formed phonetic…

In this paper we present an unsupervised neural network model of bilingual lexical development and interaction. We focus on how the representational structures of the bilingual lexicons can emerge, develop, and interact with each other as a function of the learning history. The results show that: (1) distinct representations for the two lexicons…

A controversial issue in bilingual research is whether in the early stages of L2 learning, access to the conceptual system involves mediation of L1 lexical representations [Kroll, J. F., & Stewart, E. (1994). Category interference in translation and picture naming: Evidence for asymmetric connections between bilingual memory representations.…

Examines research on learning related vocabulary, such as lexical sets, a unit of vocabulary or specific items sharing certain formal or semantic features. This research shows that learning related words at the same time makes learning them more difficult and suggests that this difficulty can be avoided if related words are learned separately.…

We assessed the impact of visual similarity on written word identification by having participants learn new words (e.g. BANARA) that were neighbours of familiar words that previously had no neighbours (e.g. BANANA). Repeated exposure to these new words made it more difficult to semantically categorize the familiar words. There was some evidence of…

A study of the effects of learning Swedish as a third language on the previously-learned English of native Finnish-speaking students examined 10,000 English-language school-leaving examinations of Finnish students for possible examples of Swedish influence in vocabulary, grammar, and word order. The examinations were those graded by a native…
