The fluency task, which involves lexical retrieval from a categorical or thematic prompt, has been a crucial paradigm in studies about lexicon in bilingualism and additional languages. Particularly, there has been a very productive cognitive turn towards analytical models based on the exploration of the cognitive processes underlying the mental…

This study reports on findings from two experiments investigating the interpretive patterns of overt pronouns in an embedded subject position with three types of matrix subjects (i.e. a referential NP, a quantified NP, or a "wh"-phrase) in Mandarin, English, and Japanese. According to the Overt Pronoun Constraint (OPC), overt pronouns in…

Since the beginning of the 21st century, heritage language studies have drawn unprecedented attention from language-related research areas. Despite the flourishing research on heritage language learning, relatively few studies have examined the motivational profiles of L1 English speakers engaged in heritage language learning. Theoretical…

The availability of a first language translation equivalent (i.e., congruency) has repeatedly been shown to influence second-language collocation processing in decontextualized tasks. However, no study to date has examined how L2 speakers process congruent/incongruent collocations on-line in a real-world context. The present study aimed to fill…

Research has shown that non-native background languages (L2s) can play an important role in the acquisition of an L3/L[subscript n]. However, only a few studies have focussed on positive transfer from an L2 to an L3/Ln in the context of multilingual language acquisition of Romance past tenses. The present study therefore analyses the acquisition…

This study explored the effect of speaking task on midclause pausing characteristics in the L1 and L2 speech of the same speakers to gain further insights into the potential relationship between pause location and stages of speech production. Participants included English L1 learners of L2 French (n = 29) or Spanish (n = 27) from the publicly…

The Global Engineers Languages and Skills (GELS) framework, developed as a language-neutral framework of engineering-specific communication skills, was adapted in 2023 for Japanese to address the language's unique linguistic and cultural features. Adjustments included subdividing beginner levels, adding a guideline for learning the complex writing…

High variability pronunciation training (HVPT) has been found to be successful for training various segmentals, such as the challenging /l/-/[voiced alveolar approximant]/ contrast, and suprasegmental features such as tone and pitch accent. These studies have found that HVPT is an effective method not only in helping learners improve their…

We investigated spaced retrieval and restudying in 3 preregistered, online experiments. In all experiments, participants studied 40 Swahili-English word pair translations during an initial study phase, restudied intact pairs or attempted to retrieve the English words to Swahili cues twice in three spaced practice sessions, and then completed a…

Transparency in assessments means ensuring their validity, reliability and authenticity. While it remains limited in practice when administering internationally validated literacy assessment tools, one major factor necessitates transparently reporting achievement results in light of learners' linguistic repertoires. Sitting these literacy…

Technology-enhanced learning environments (TELEs) have provided language learners with various opportunities to promote their self-sufficient learning outside the classroom lately. Thus, language learners are no longer passive recipients of language; in contrast, they are autonomous learners who apply self-regulated learning strategies through the…

Second language (L2) research on input manipulation has focused mainly on increasing the salience of target structures, but presentation formats of L2 input can be another important aspect for manipulation. This study compared the horizontal, vertical, and adjacent formats for presenting the characters, pinyin, and English meaning of L2 Chinese…

Language learning is a complex issue of interest to linguists, computer scientists, and psychologists alike. While the different fields approach these questions at different levels of granularity, findings in one field profoundly affect how the others proceed. My dissertation examines the perceptual and linguistic generalizations regarding the…

The present study investigated the relation between continuous measures of two qualitatively different types of bilingual experience and outcome measures that varied in domain (verbal or nonverbal) and processing demands (degree of conflict). Participants were 195 English-speaking children, 7 years old, who were enrolled in French immersion…

Purpose: Bilingual children's speech often contains high percentages of disfluencies in both their languages; however, the distribution of disfluency types and the difference across bilinguals' two languages have received insufficient and inconsistent empirical support. The present research aims to profile "typical" bilingual disfluency…
