Research investigating L2 (second language) willingness to communicate (WTC) has gained ground in the past two decades. Added to that is the emergence of complex dynamic systems theory (CDST) with a focus on the phenomenon of change, the implications of which for WTC research have opened up new avenues to enhance our conceptualization of the…

The globally widespread instant messaging (IM) mobile applications such as WhatsApp or Telegram were not originally educational tools, but they have become platforms for peer to peer assessment (P2P). The IM applications offer "chatbots" or "virtual assistant bots" that help students by providing them a multitude of services in…

This study investigated the extent to which parental language input to children with hearing loss (HL) prior to cochlear implant (CI) differs from input to children with typical hearing (TH). A 20-min parent-child interaction sample was collected for 13 parent-child dyads in the HL group and 17 dyads in the TH group during free play. Ten minutes…

Purpose: Cochlear implants (CIs) transmit a degraded version of the acoustic input to the listener. This impacts the perception of harmonic pitch, resulting in deficits in the perception of voice features critical to speech prosody. Such deficits may relate to changes in how children with CIs (CCIs) learn to produce vocal emotions. The purpose of…

Phonological selectivity is a phenomenon where children preselect which target words they attempt to produce. The present study examines selectivity in the acquisition of complex onsets and codas in English, and specifically in the acquisition of biconsonantal (CC) clusters in each position compared to triconsonantal (CCC) clusters. The data come…

Purpose: The study sets out to investigate inter- and intraspeaker variation in German infant-directed speech (IDS) and considers the potential impact that the factors gender, parental involvement, and speech material (read vs. spontaneous speech) may have. In addition, we analyze data from 3 time points prior to and after the birth of the child…

Through two elicited production experiments we investigated how preschool Italian-speaking children access the left periphery of the clause with respect to topics in Clitic Left Dislocation (ClLD) structures. Since the discourse conditions of the experiments are felicitous for the production of passives as well, we also investigated children's…

This mixed-methods study examined academic oral communication difficulties encountered by Yemeni postgraduate students in a Malaysian public university and how they overcome these difficulties. The study also examined the correlation between students' academic oral communication difficulties and their prior learning experience. Questionnaires,…

Objective: The purpose of this systematic review is to evaluate the published research in auditory training (AT) for pediatric cochlear implant (CI) recipients. This review investigates whether AT in children with CIs leads to improvements in speech and language development, cognition, and/or quality of life and whether improvements, if any,…

This dissertation explores three novice nonnative English-speaking doctoral students' experiences with academic speaking and writing practices and speaking-writing connections during their first year of doctoral study in the language education program at a Research One university in the U.S. By adopting the sociocognitve theoretical framework…

The purpose of this study was to investigate to what extent bi-modal input improves the word segmentation ability of L2 learners of Japanese. Accurately identifying words in continuous speech is a fundamental process for comprehending the overall message, but studies show that second language (L2) learners often find this task difficult, even when…

We examined whether speech-related differences between truth tellers and liars are more profound when answering unexpected questions than when answering expected questions. We also examined whether the presence of an interpreter affected these results. In the experiment, 204 participants from the United States (Hispanic participants only), Russia,…

Visual and auditory information jointly contribute to face categorization processes in humans, and gender is a socially relevant multisensory category specified by faces and voices that is detected early in infancy. We used an eye tracker to study how gender coherence in audio and visual modalities influence face scanning in 9- to 12-month-old…

Purpose: The purpose of this study was to evaluate whether listeners with normal hearing perceiving noise-vocoded speech-in-speech demonstrate better intelligibility of target speech when the background speech was mismatched in language (linguistic release from masking [LRM]) and/or location (spatial release from masking [SRM]) relative to the…

In this work we ask whether at birth, the human brain responds uniquely to speech, or if similar activation also occurs to a non-speech surrogate 'language'. We compare neural activation in newborn infants to the language heard "in utero" (English), to an unfamiliar language (Spanish), and to a whistled surrogate language (Silbo Gomero)…
