This mosaic essay reflects on the invitation to speak to a JME symposium on Education and Climate Change and the convenors' request for participants to engage with the previous history of scholarship on education and environment in this journal. It begins by recognising that the world is still confronting deepening ecological and climate…

Purpose: Some bilinguals may exhibit lower performance when recognizing speech in noise (SiN) in their second language (L2) compared to monolinguals in their first language. Poorer performance has been found mostly for late bilinguals (L2 acquired after childhood) listening to sentences containing linguistic context and less so for…

Abundant research has indicated fluency features as meaningful predictors of second language proficiency. However, the extent to which different fluency dimensions and features can predict proficiency remains underexplored. This meta-analysis employed a multilevel modeling approach to synthesize fluency-proficiency relationships from 71 empirical…

Hidden structure refers to the units of organization that a child cannot directly observe when they are learning language (e.g. phonemes, morpheme boundaries, URs, phrases). In this dissertation, I propose a novel computational model that learns hidden structures in-tandem with the grammar. My model consists of two Maximum Entropy sub-models that…

The current trend of speakers of English as a second or an additional language (English language learners) outnumbering speakers of English as a first language (native English speakers) has shifted the focus of English language teaching from the nativeness principle to the intelligibility principle. Following the intelligibility principle, this…

The boundary effect, namely the infants' failures to compare small and large numerosities, is well documented in studies using visual stimuli. The prevailing explanation is that the numerical system used to process sets up to 3 is incompatible with the system employed for numbers >3. This study investigates the boundary effect in 10-month-old…

Past studies have shown that first language and second language (L2) listeners can adapt to unfamiliar L2 pronunciation. However, little is known about the process of adaptation, especially by L2 listeners. The present study examined the degree to which L2 listeners' adaptation process is influenced by speaker intelligibility and input…

We compare two frameworks for the segmentation of words in child-directed speech, PHOCUS and MULTICUE. PHOCUS is driven by lexical recognition, whereas MULTICUE combines sub-lexical properties to make boundary decisions, representing differing views of speech processing. We replicate these frameworks, perform novel benchmarking and confirm that…

Students need to know how to communicate succinctly. Often, students struggle to determine how much content is necessary to communicate a message. Designed for courses on public speaking, interpersonal communication, and organizational communication, this activity invites students to tell their class a story using a single sentence. After…

Introduction: Narratives are enriched by taking the perspective of the protagonists, which can be expressed using reported speech. Nevertheless, the use of reported speech is unaddressed internationally among individuals with Down syndrome. Method: Narratives of 28 children and adolescents with Down syndrome were collected using a non-verbal…

Noise is a common impedance to easy and accurate speech understanding. In the presence of noise, speech processing mechanisms proceed with partial or ambiguous inputs, and listeners will engage additional cognitive resources to make sense of what they hear. The extent to which this is situation is affected by diminished exposure to a language is…

The prevalent "core phonological deficit" model of dyslexia proposes that the reading and spelling difficulties characterizing affected children stem from prior developmental difficulties in processing speech sound structure, for example, perceiving and identifying syllable stress patterns, syllables, rhymes and phonemes. Yet spoken word…

Before you got into leadership, did you expect you'd be doing so much speaking? It seems you're always talking--in faculty meetings and one-on-one evaluations; in PD sessions and department meetings; at parents' night and awards ceremonies; to colleagues, supervisors, and the school board; and in front of dozens or hundreds or just a webcam and a…

This study examined the effect of a serial multiple exemplar training (S-MET) procedure on bidirectional naming (BiN) in four preschool children diagnosed with autism spectrum disorder (ASD). A non-concurrent multiple baseline design was used to evaluate the effects of training listener and speaker behavior for one stimulus at a time until BiN…

Projecting confidence during conversation or presentation is a critical skill. To effectively display confidence, speakers must employ a blend of verbal and non-verbal signals. A predictive model that leverages rich multimodal cues to measure a speaker's confidence must also mitigate biases that develop through data labelling practices, inherent…
