Background: Within cohorts of children with autism spectrum disorder (ASD) there is considerable variation in terms of language ability. In the past, it was believed that children with ASD either had delayed articulation and phonology skills or excelled in those areas compared to other language domains. Very little is known about speech sound…

I'm a special educator whose classroom was next door to the homeroom of my hard of hearing son. I had him as one of my students for special education literacy three times a week. I was fortunate to have the professional background, personal knowledge, and treasured relationships with colleagues -- all of which helped me navigate the experience of…

Interaction between generations is diminishing and fostering intergenerational contact can benefit both parties involved. The aim of this qualitative study was to develop a deeper understanding of the meaning of participating in an intergenerational oral history project using a phenomenological approach. Undergraduate students (n = 21) interviewed…

The developmental trajectory of audiovisual speech perception in Mandarin-speaking children remains understudied. This cross-sectional study in Mandarin-speaking 3- to 4-year-old, 5- to 6-year-old, 7- to 8-year-old children, and adults from Xiamen, China (n = 87, 44 males) investigated this issue using the McGurk paradigm with three levels of…

Word identification accuracy is modulated by many factors including linguistic characteristics of words (frequent vs. infrequent), listening environment (noisy vs. quiet), and listener-related differences (older vs. younger). Nearly, all studies investigating these factors use high-familiarity words and noise signals that are either energetic…

In this dissertation, I investigate how people navigate ambiguity in everyday speech, with a focus on quantifier-negation sentences. Combining corpus analysis, behavioral experiments, and computational modeling in the Rational Speech Act framework, I explore preferred interpretations of quantifier-negation and examine the contexts and prosodies…

Narrative language skills are important for academic and social success. The ability to produce well-formed and coherent spoken narratives has been shown to be highly correlated with proficient reading and writing (Kirby, Spencer, & Chen, 2021; Spencer & Petersen, 2018; Petersen et al., 2020). The importance of narrative abilities for…

In spoken languages, children acquire locative terms in a cross-linguistically stable order. Terms similar in meaning to in and on emerge earlier than those similar to "front" and "behind," followed by "left" and "right." This order has been attributed to the complexity of the relations expressed by…

Ageing is associated with elevated pure-tone thresholds, accompanied by increased difficulties in understanding speech-in-noise. While amplification provides important, but insufficient support, auditory-cognitive training (ACT) might propose a solution. However, generalized effects have been scarce, highlighting the necessity of training designs…

High school students attending Flexible Learning Programmes (FLPs) experience more speech, language, and communication needs (SLCN) than those in mainstream, which may impact their academic engagement, socioemotional health, and future employment. We explored the effectiveness of a pilot workshop designed to increase educators' confidence to…

This study reports about the vlog (video blog) integration as a learning media in three different cohorts of Indonesian EFL speaking classrooms. Those cohorts were college students enrolled in the Speaking III class available in the third semester. This class required students to be able to demonstrate speaking skills. There were 29 participants…

This study investigates the speech rate of Cypriot Greek-speaking children with developmental language disorder (DLD) as well as the effect of age and gender. The participants were 16 children with DLD ages 4 years 11 months to 8 years 1 month and 22 children with typical language development (TLD) ages 4 years 5 months to 8 years 7 months. Both…

This study investigates the effectiveness of TED Talks in enhancing EFL university students' English-speaking skills for presentations. Despite the widespread use of TED Talks in language learning, limited research has examined their specific impact on overall presentation skills, including fluency, pronunciation, anxiety, and confidence in…

This longitudinal study (data collected from 2019 to 2023) examines the relation between Spanish-English bilingual Latino toddlers' (n=46; F=22; M=24) early gesture production (Mage=18.67 months; SD[subscript age]=1.02) and later language skills (M[subscript age]=36.87 months; SD[subscript age]=0.81). Video recordings at child-age 18-months…

Cognitive behaviour therapy (CBT) is a common and proven way to treat anxiety. In language learning settings, CBT has been shown to remedy students' anxiety and help them actively engage with a new language. However, research is inconclusive on how to best approach CBT-based interventions for language learning, and how to cater to students'…
