Purpose: This study investigated vowel and sibilant productions in noise to determine whether responses to noise (a) are sensitive to the spectral characteristics of the noise signal and (b) are modulated by the contribution of vowel or sibilant contrasts to word discrimination. Method: Vowel and sibilant productions were elicited during serial…

To secure mutual understanding in interaction, speakers sometimes explain or negotiate expressions. Adopting a conversation analytic and interaction linguistic approach, I examine how participants explain which kinds of expressions in different sequential environments, using the format "x heißt y" ("x means y"). When speakers…

Children's speech is influenced by the speech they hear, in particular by the parental speech addressed directly to them. The aim of this study was to analyse toddlers' speech with their parents and to investigate the influence of specific characteristics of child-directed speech on child speech in real time during mother-child and father-child…

Children with complex communication needs often have multiple disabilities including visual impairments that impact their ability to interact with aided augmentative and alternative communication (AAC) systems. Just as the field benefited from a consideration of visual cognitive neuroscience in construction of visual displays, an exploration of…

Purpose: Utilizing datasets of Ecuador, Hungary, Kazakhstan, Mexico and Peru from the Programme for the International Assessment of Adult Competencies survey from 2017 to 2018, this study aimed to develop and validate a profile indicating core workplace skills in developing countries. Design/methodology/approach: DeVellis' guide of scale…

The ability to associate different types of number representations referring to the same quantity (symbolic Arabic numerals, signed/spoken number words, and nonsymbolic quantities), is an important predictor of overall mathematical success. This foundational skill--mapping--has not been examined in deaf and hard-of-hearing (DHH) children. To…

Collaboration is argued to be an important skill, not only in schools and higher education contexts but also in the workspace and other aspects of life. However, simply asking students to work together as a group on a task does not guarantee success in collaboration. Effective collaborative learning requires meaningful interactions among…

To support improved understanding of interaction among the heterogeneous people with aphasia who attend facilitated conversation groups we applied discourse structure analysis (DSA). We focused on group members with mild and severe aphasia. We identified the function of each communicative move, an utterance unit core to DSA, individuals made in…

Purpose: Individuals diagnosed with autism spectrum disorder (ASD) often exhibit auditory processing issues, including poor speech recognition in background noise and dichotic processing (integration of different stimuli presented to the two ears). Auditory training could mitigate these auditory difficulties. However, few auditory training…

This study explored the effect of ChatGPT on the speaking self-efficacy level of English as foreign language learners. The research followed the mixed method approach and involved a total of 65 participants who were randomly assigned to the experimental and control groups. The experimental group used the ChatGPT for communicative activities, while…

Second language (L2) learners hold different learning beliefs that influence their interpretation of classroom experiences and their L2 learning process. Developing a thorough understanding of such beliefs is therefore imperative. This article reports the representations of Iranian English-as-a-foreign-language (EFL) learners' beliefs about L2…

Purpose: We explore a new approach to the study of cognitive effort involved in listening to speech by measuring the brain activity in a listener in relation to the brain activity in a speaker. We hypothesize that the strength of this brain-to-brain synchrony (coupling) reflects the magnitude of cognitive effort involved in verbal communication…

This full paper considers how collaborative discourse can reveal ways upper-class engineering students mechanically reason about engineering concepts. Argumentation and negotiation during collaborative, multimodal discourse using speech and gestures helps establish common ground between learners and fosters reflection on their conceptual…

General chemistry courses serve as foundational curriculum within most STEM undergraduate curricula, and hence, it is essential to assess student knowledge and application of learning outcomes for courses such as Introduction to Chemistry and Organic Chemistry. Within the United States, paper-and-pencil examinations are typical for measuring…

This study examined putative benefits of testing and production for learning new languages. Undergraduates (N = 156) were exposed to Turkish spoken dialogues under varying learning conditions (retrieval practice, comprehension, verbal repetition) in a computer-assisted language learning session. Participants completed pre- and posttests of number-…
