Echo phonology was originally proposed to account for obligatory coordination of manual and mouth articulations observed in several sign languages. However, previous research into the phenomenon lacks clear criteria for which components of movement can or must be copied when the articulators are so different. Nor is there discussion of which…

Previous evidence suggests that children's mastery of prosodic modulations to signal the informational status of discourse referents emerges quite late in development. In the present study, we investigate the children's use of head gestures as it compares to prosodic cues to signal a referent as being contrastive relative to a set of possible…

This research investigated whether observing beat gesture and hearing contrastive accenting with novel words enhances their learning in early childhood and whether these effects differ by sex in light of sex differences in the pace of language development. Fifty-three 3- to 5-year-old boys and girls learned pairs of novel words with contrasting…

Background: Teachers' behaviours drive motivational climates that shape children's engagement and well-being in the classroom, but few studies examine how specific teachers' behaviours such as wording, body language, or voice contribute to these outcomes in isolation of one another. Aims: This pre-registered experiment sought to examine the…

This article reviews research findings involving visual input in speech processing in the form of facial cues and co-speech gestures for second-language (L2) learners, and provides pedagogical implications for the teaching of listening and speaking. It traces the foundations of auditory-visual speech research and explores the role of a speaker's…

In this study, 118 native speakers of Japanese watched 48 separate video clips in which a teacher provided recasts on phonological or lexical errors to students in Portuguese, a language with which the participants were unfamiliar. In the video clips, six recast characteristics were manipulated: length, segmentation (segmented/whole), prosodic…

Collaborative learning is a complex process during which two or more learners exchange opinions, construct shared knowledge, and solve problems together. While engaging in this interactive process, learners' satisfaction toward their partners plays a crucial role in defining the success of the collaboration. If intelligent systems could predict…

The acoustic realization of phrasal prominence is proposed to correlate with the order of V(erbs) and O(bjects) in natural languages. The present production study with 15 talkers of Japanese (OV) and English (VO) investigates whether the speech signal contains coverbal visual information that covaries with auditory prosody, in Infant- and…

Language classroom interactions can be characterized as multimodal, since teachers may resort to a variety of resources provided by their body or by their immediate space in order to convey meaning, manage activities and assess pupils' performances. Furthermore, teachers' multimodal practices constitute an essential component for the…

Recent experiments have shown that people iconically modulate their prosody corresponding with the meaning of their utterance (e.g., Shintel et al., 2006). This article reports findings from a story reading task that expands the investigation of iconic prosody to abstract meanings in addition to concrete ones. Participants read stories that…

Children achieve their first language milestones initially in gesture and prosody before they do so in speech. However, little is known about the potential precursor role of those features later in development when children start using more complex linguistic skills. In this study, we explore how children's ability to reflect on their degree of…

The ability to present effectively is essential for professionals; therefore, oral communication courses have become part of the curricula for higher education studies. However, speaking in public is still a challenge for many graduates. To tackle this problem, driven by the recent advances in computer vision techniques and prosody analysis,…

It is yet unclear whether congenitally deaf cochlear implant (CD CI) users' visual and multisensory emotion perception is influenced by their history in sign language acquisition. We hypothesized that early-signing CD CI users, relative to late-signing CD CI users and hearing, non-signing controls, show better facial expression recognition and…

This study investigates the perception and production of a specific type of metaphoric gesture that mimics melody in speech, also called "pitch gesture," in the learning of L2 suprasegmental features. In a between-subjects design, a total of 106 participants with no previous knowledge of Chinese were asked to observe (Experiment 1) and…

Using a novel emotional perspective-taking task, this study investigated 4-year-olds' (n = 97) use of a speaker's emotional prosody to make inferences about the speaker's emotional state and, correspondingly, their communicative intent. Eye gaze measures indicated preschoolers used emotional perspective inferences to guide their real-time…
