The study explores whether racial identity and appearance-based trustworthiness judgments can affect recognition of pain in medical students differing in levels of resting heart rate variability (HRV), a measure of parasympathetic control of the heart. After undergoing HRV assessment, 68 medical students (37 females) participated in a dynamic pain…

One limitation of the naturalistic observation method is that it is understudied how accurately personal relationships may be judged by observers in real-life settings. To assess this judgment accuracy, we observed 285 dyads of individuals in public places and then asked whether they were affiliated or strangers. We found that human observers were…

Gestures accent and illustrate our communication. Although previous studies have uncovered the positive effects of gestures on communication, little is known about the specific cognitive functions of different types of gestures, or the instantaneous multi-brain dynamics. Here we used the fNIRS-based hyperscanning technique to track the brain…

The improvements in attention by mindfulness training have been proved. However, the effects of mindfulness training on attention to emotional stimuli were mixed. We employed a randomized, controlled design to investigate the effects of mindfulness training on attention to emotional expressions, and investigated whether baseline levels of…

In an attempt to shed light on the social decision difficulties experienced by autistic adults, the current study examines the dynamics of experience-based social decisions. We developed an experiential task where participants' goal was to select the most kind and pleasant agent out of four, based on the valence (positivity/negativity) of the…

Co-speech gesture in monolinguals has been linked to several cognitive processes: prompting memory stores, conveying spatial concepts, searching for lexical equivalents, and supporting rhythm and cohesion. The production of co-speech gesture also occurs in spoken language bilinguals. Studies have demonstrated that bilinguals fluent in American…

In e-learning environments, most adaptive systems do not consider the learner's emotional state when recommending activities for learning difficulties, blockages, or demotivation. In this paper, we propose a new approach of emotion-based adaptation in e-learning environments. The system will allow recommendation resources/activities to motivate…

Research on gesture development has mostly focused on home environments. Little is known about early communicative development in other relevant contexts, such as early-year-schools. These settings, rich in diverse educative situations, objects, and communicative partners, provide a contrast to parent-child interactions, complementing our…

The purpose of the current study was to extend the findings on the use of the go/no-go successive matching-to-sample (S-MTS) procedure to establish auditory equivalence classes. Eight college students learned to conditionally relate nonverbal auditory stimuli into three, 3-member classes. Following training, all participants met the emergence…

We examine relationships between interviewers' nonverbal behaviors and adequate responding in face-to-face survey interviews. We videotaped professional interviewers administering face-to-face survey interviews and coded them for three interviewer nonverbal behaviors: smiling, nodding, and direct gaze. These nonverbal interviewer behaviors were…

Researchers have long been interested in the origins of humans' understanding of symbolic number, focusing primarily on how children learn the meanings of number words (e.g., "one", "two", etc.). However, recent evidence indicates that children learn the meanings of number gestures before learning number words. In the present…

The aim of this research was to analyze the use of iconicity during language acquisition of Israeli Sign language and spoken Hebrew. Two bilingual-bimodal infants were observed in a longitudinal study between the ages of 10-26 months. I analyzed infants' production of iconic words, signs, and gestures. The results showed that infants' use of vocal…

Additional language (L2/Ln) research largely focuses on learners whose first languages are spoken and who are learning additional spoken languages. In the past few decades, sign languages have become increasingly popular for hearing students in schools. These students must not only learn the vocabulary and grammar of sign languages but also manage…

In this paper, we aimed to examine what characterizes teachers' interactions with children in micro-level transitions in Norwegian preschools. We used video and observed transitions at the micro level, such as between meal and sleeping time, and between playing and meals. The participants were 22 teachers from 22 classrooms in 17 preschools. We…

Background: Prelinguistic communication complexity refers to the use of different communication forms such as eye gaze, gestures and vocalisations and the degree to which these forms are coordinated and how directed to a communication partner. To date, little is known about the relationship between prelinguistic communication complexity and…
