Metacognitive reasoning is central to decision-making. For every decision, we can also judge our trust in that decision, or our level of "confidence." The mechanisms and representations underlying reasoning about confidence remain debated. We test whether children rely on "processing fluency" to infer their own confidence: do…

Purpose: The purpose of this study was to determine if there are age-related differences in semantic processing with linguistic and nonlinguistic masking, as measured by the N400. Method: Sixteen young (19-31 years) and 16 middle-aged (41-57 years) adults with relatively normal hearing sensitivity were asked to determine whether word pairs were…

Multilingual speakers can find speech recognition in everyday environments like restaurants and open-plan offices particularly challenging. In a world where speaking multiple languages is increasingly common, effective clinical and educational interventions will require a better understanding of how factors like multilingual contexts and…

This article comprises two international studies. Study 1 aimed to develop a scale to measure the frequency of learners' voluntary, informal, out-of-school engagement with English, so-called Extramural English (EE) activities. It involved three stages -- pilot study, exploratory factor analysis, and confirmatory factor analysis -- followed by…

One of the notable language difficulties experienced by healthy older adults is word retrieval failure, specifically the tip-of-the-tongue state (TOT). A TOT occurs when one has a strong sense of knowing the word, such that the semantic content is accessed, but the entirety of the word's phonology is temporarily inaccessible. Such retrieval…

As there is a growing population of non-native speakers worldwide, facilitating communication involving native and non-native speakers has become increasingly important. While one way to help communication involving native and non-native speakers is to help non-native speakers improve proficiency in their target language, another way is to help…

While developmental dyslexia has been extensively studied in children, research on adults is still rather limited. This paper aims to bridge the gap in existing research by presenting the findings of a study that examined the reading and spelling skills of adults with dyslexia and assessed the effectiveness of a linguistic intervention designed to…

Foreign Language Speaking Anxiety (FLSA) is known to negatively affect the performance of foreign language learners. Among the four language skills, speaking is the most anxiety-provoking skill. We investigated the presence of FLSA in Indonesian vocational high school students and we tested whether web-based language learning might help to reduce…

While speaking anxiety is one of the most problematic aspects observed in English as a foreign language (EFL) context, a limited number of studies focused on the impact of collaborative learning on speaking anxiety in different learning environments. This study investigates the effects of collaborative tasks on foreign language learners' speaking…

English medium instruction (EMI) is seen as a site for improving students' English language, yet the role of the EMI lecturer in achieving this is contested. Views on what constitutes appropriate training and professional development for EMI lecturers also differ regarding English language skills and EMI-specific methodology. Using Q methodology,…

Children tend to regularize their productions when exposed to artificial languages, an advantageous response to unpredictable variation. But generalizations in natural languages are typically conditioned by factors that children ultimately learn. In two experiments, adult and six-year-old learners witnessed two novel classifiers, probabilistically…

This study investigated whether teacher expectation effects on students' foreign language learning would be moderated by students' perceptions of the classroom environment. The participants were 28 teachers and 1030 first-year undergraduate students learning English as a foreign language from public universities in China. Data for teacher…

Understanding the changes in our language abilities along the lifespan is a crucial step for understanding the aging process both in normal and in abnormal circumstances. Besides controlled experimental tasks, it is equally crucial to investigate language in unconstrained conversation. I present an information-theoretical analysis of a corpus of…

Prior research on pre-task planning examines its effects on the quality of second language (L2) learners' planned output. Planning mitigates the cognitive overload placed upon L2 learners' oral performance, thus improving language production. Despite the pedagogical benefits, studies on pre-task planning on L2 learners' oral output are conducted…

Large-scale learner corpora collected from online language learning platforms, such as the EF-Cambridge Open Language Database (EFCAMDAT), provide opportunities to analyze learner data at an unprecedented scale. However, interpreting the learner language in such corpora requires a precise understanding of tasks: How does the prompt and input of a…
