Korean learners of the Japanese language and Japanese learners of the Korean language not only feel that it is easier to learn the respective foreign language, but also acquire Japanese and Korean faster than learners from other countries because of the grammatical similarity between Japanese and Korean. However, the similarity of grammatical…

We explored the possibility of predicting student emotions (boredom, flow/engagement, confusion, and frustration) by analyzing the text of student and tutor dialogues during interactions with an Intelligent Tutoring System (ITS) with conversational dialogues. After completing a learning session with the tutor, student emotions were judged by the…

Two prominent dual-route computational models of reading aloud are the dual-route cascaded (DRC) model, and the connectionist dual-process plus (CDP+) model. While sharing similarly designed lexical routes, the two models differ greatly in their respective nonlexical route architecture, such that they often differ on nonword pronunciation. Neither…

What makes a discourse coherent? One potential factor has been discussed in the linguistic literature in terms of a Question under Discussion (QUD). This approach claims that discourse proceeds by continually raising explicit or implicit questions, viewed as sets of alternatives, or competing descriptions of the world. If the interlocutor accepts…

Bilinguals who are fluent in American Sign Language (ASL) and English often produce "code-blends"--simultaneously articulating a sign and a word while conversing with other ASL-English bilinguals. To investigate the cognitive mechanisms underlying code-blend processing, we compared picture-naming times (Experiment 1) and semantic categorization…

We present a neural network model of learning and processing the English past tense that is based on the notion that experience-dependent cortical development is a core aspect of cognitive development. During learning the model adds and removes units and connections to develop a task-specific final architecture. The model provides an integrated…

This study explores how elementary teachers and students use hedges (tentative words such as "maybe") and boosters (expressions of certainty such as "clearly" and "obviously") during science inquiry discussions. Drawing upon semiotic theory, we examine explicit thematic patterns (semantic meaning relations among science concepts) as well as hidden…

Abundant research has shown that encoding meaningful gesture, such as an iconic gesture, enhances memory. This paper asked whether gesture needs to carry meaning to improve memory recall by comparing the mnemonic effect of meaningful (i.e., iconic gestures) and nonmeaningful gestures (i.e., beat gestures). Beat gestures involve simple motoric…

Using the eye-movement monitoring technique in two reading comprehension experiments, this study investigated the timing of constraints on wh-dependencies (so-called island constraints) in first- and second-language (L1 and L2) sentence processing. The results show that both L1 and L2 speakers of English are sensitive to extraction islands during…

In this study we examined asymmetric semantic activation patterns as people listened to conversations and narratives that promoted causal inferences. Based on the hypothesis that understanding the unique features of conversational input may benefit from or require a modified pattern of conceptual activation during conversation, we compared…

Background: Structural language anomalies or impairments in autistic spectrum disorder (ASD) are theoretically and practically important, although underrecognised as such. This review aims to highlight the ubiquitousness of structural language anomalies and impairments in ASD, and to stimulate investigation of their immediate causes and…

College students in the United States and in South Korea completed a 28-item multidimensional scaling (MDS) questionnaire in which they rated the similarity of 28 pairs of multimedia learning materials on a 10-point scale (e.g., narrated animation on a mobile device Vs. movie clip on a desktop computer) and a 56-item semantic differential…

Much recent work argues that lexical frequency plays a central explanatory role in linguistic theory, but the status, predicted effects, and methodological treatment of frequency are controversial, especially so in the less-investigated area of syntactic variation. This article addresses these issues in a case study of lexical frequency effects on…

The Indian Institute of Science is proud to host the fully in-person sixteenth iteration of the International Conference on Educational Data Mining (EDM) during July 11-14, 2023. EDM is the annual flagship conference of the International Educational Data Mining Society. The theme of this year's conference is "Educational data mining for…

Interdisciplinary collaboration is a cornerstone of WAC/WID efforts and integral to productive relationships between writing specialists and disciplinary content experts. Such collaboration, however, suffers from welldocumented challenges. In this article, I use textual discourse analysis to build a deeper understanding of the discursive spaces…
