Interpreting three-dimensional models of biological macromolecules is a key skill in biochemistry, closely tied to students' visuospatial abilities. As students interact with these models and explain biochemical concepts, they often use gesture to complement verbal descriptions. Here, we utilize an embodied cognition-based approach to characterize…

Successful computer-supported collaborative learning (CSCL) relies on collaborative group engagement, a complex construct characterized by multifaceted, dynamic, socio-emotional, and socio-cognitive processes. This paper provides a detailed analysis of collaborative group engagement, with a particular focus on nonverbal behaviors as indicators of…

During face-to-face conversation, transitions between speaker turns are incredibly fast. These fast turn exchanges seem to involve next speakers predicting upcoming semantic information, such that next turn planning can begin before a current turn is complete. Given that face-to-face conversation also involves the use of communicative bodily…

This study investigates the function of smiling intensity as a nondiscrete marker of humor in conversation. The smiling intensity of participants in eight conversational dyads was measured relative to the occurrence of humorous and nonhumorous events in the conversation. A relationship was found between higher smiling intensity and the occurrence…

A defining feature of ASD is atypical gaze behaviour, however, eye-tracking studies in 'real-world' settings are limited, and the possibility of improving gaze behaviour for ASD children is largely unexplored. This study investigated gaze behaviour of ASD and typically developing (TD) children in their classroom setting. Eye-tracking technology…

This article focuses on the relationship between gaze and recipient feedback in triadic storytelling activities. Our starting point to investigate this relationship is an article by Bavelas et al. (2002), who report a statistically significant interaction between feedback and so-called gaze windows in dyadic storytelling activities. The pattern…

Gender differences are manifested not only in the physiological characteristics of a person, but also in the speech communication. This article presents the research data obtained at the phonetic and lexical levels of the language. The purpose of this work is to determine the speech characteristics that distinguish men and women at the studied…

In this article, I present my view on the significant developments and theoretical/empirical tipping points in nonverbal and verbal deception and lie detection from the last 30 years and on prospects for future research in this domain. I discuss three major shifts in deception detection research: (a) From observing target persons' nonverbal…

Affirmative consent initiatives advocate that college students understand sexual consent and refusal. There has been an influx of research focused on students' definitions or understanding of consent; however, research examining students' definitions of sexual refusals is limited. Additionally, different terminology (e.g., non-consent vs. sexual…

The present work examines the impact of code-switching (CS) on novel word learning in adult second language (L2) learners of Spanish. Participants completed two sessions (1-3 days apart). In the first session, they were taught 32 nonwords corresponding to novel creatures. Training occurred across 4 conditions: (1) a sentence in English only, (2) a…

This study examined Iranian English as a Foreign Language (EFL) teachers' perceptions and use of politeness strategies in oral classroom discourse. In so doing, 29 EFL teachers were selected, and their classroom conversations with their students were audio-taped and observed. Further, ten teachers were interviewed to provide a deeper insight into…

Behaviors such as gaze aversion and repetitive movements are commonly believed to be signs of deception and low credibility; however, they may also be characteristic of individuals with developmental or mental health conditions. We examined the effect of five behaviors that are common among autistic individuals--gaze aversion, repetitive…

Learning involves a substantial amount of cognitive, social and emotional states. Therefore, recognizing and understanding these states in the context of learning is key in designing informed interventions and addressing the needs of the individual student to provide personalized education. In this paper, we explore the automatic detection of…

Starting in the preschool years, children show socially exclusive behaviors, such as intentionally leaving out another child from a ball game. Prior research investigating social exclusion understanding in preschoolers primarily used interview methods and it is clear that the verbal and cognitive skills necessary to identify and reason about…

Collaborative dialogue is rich in conscious and subconscious coordination behaviours between participants. This work explores collaborative learner dialogue through theories of alignment, analysing inter-partner movement and language use with respect to our hypotheses: that they interrelate, and that they form predictors of collaboration quality…
