Purpose: The aim of this study was to describe changes in speech intelligibility and interrater and intrarater reliability of naive listeners' ratings of words produced by young children diagnosed with childhood apraxia of speech (CAS) over a period of motor-based intervention (dynamic temporal and tactile cueing [DTTC]). Method: A total of 120…

In the search for mechanisms that contribute to dyslexia, the term "attention" has been invoked to explain performance in a variety of tasks, creating confusion since all tasks do, indeed, demand "attention." Many studies lack an experimental manipulation of attention that would be necessary to determine its influence on task…

Segmentation is a cornerstone of language processing across levels of linguistic analysis, and yet, standard models of linguistic memory leave the role of higher-order segments in online comprehension understudied. This dissertation advances the Context-Sensitive Encoding (CSE) hypothesis: that implicit prosodic boundaries (Bader, 1998; J. Fodor,…

Children learn words in a social environment. In my dissertation, I examine how caregivers' social cues facilitate young children's word learning in settings that mirror their typical, dynamic learning environments. In Chapter 1, I overview prior work examining how social cues may support word learning, focusing on possible mechanisms underlying…

Incorporating virtual reality (VR) technology into training environments has been effective as it allows training to remain safe, efficient, and meaningful. Welding training is no exception, with research highlighting benefits such as decreased welder anxiety, increased cost- and time-efficiency, reduction in material usage, and advanced levels of…

Infant-directed speech (IDS) produced in laboratory settings contains acoustic cues, such as pauses, pitch changes, and vowel-lengthening that could facilitate breaking speech into smaller units, such as syntactically well-formed utterances, and the noun- and verb-phrases within them. It is unclear whether these cues are present in speech produced…

Differentiation of speech is predictable from abilities to discriminate the speed at which a sound reaches its optimum amplitude (rise time). This study investigated whether rise time identification of an affricate-fricative continuum would be impacted upon by dyslexia. Children between 10 and 14 years old identified sounds along a continuum of…

Which behavioral and visual information do teachers rely on when judging relevant characteristics of their students and which cues should they rely on? Drawing on Brunswik's Lens Model (Perception and the representative design of psychological experiments, University of California Press, 1956. https://doi.org/10.1525/9780520350519), we…

Conversational skills, which are essential for effective social interactions and typically pose difficulties for individuals with autism spectrum disorder (ASD), include abilities such as initiating topics, engaging in back-and-forth dialog, and responding to conversational cues. Chatbots have been used in mental health fields, and the development…

Understanding language requires readers and listeners to cull meaning from fast-unfolding messages that often contain conflicting cues pointing to incompatible ways of interpreting the input (e.g., "The cat was chased by the mouse"). This article reviews mounting evidence from multiple methods demonstrating that cognitive control plays…

The empirical evidence concerning the question whether an instructor should be presented on online lecture slides is equivocal and two lines of theoretical reasoning exist. On the one hand, the instructor may distract from the content, thereby hampering learning; on the other hand, the instructor may function as a social cue that triggers a more…

Purpose: This study aimed to examine the effects of sentence context, accent strength, and second language (L2) listening proficiency on word recognition accuracy and transcription time among Chinese learners of English for Pakistani-accented English. Method: Speech stimuli included 48 isolated words and 48 highly constraining sentences, each…

This study examined an intervention package incorporating an iPad-based augmentative and alternative communication (AAC) application, Proloquo2Go, to improve wh-question-answering skills in a 15-year-old adolescent with autism. A single-case, multiple baseline design across three types of wh-questions ("what," "where," and…

In this paper I share the theorising behind the development of a model for possible use by instrumental and vocal teachers to assist with the structuring of student practice. The model is a component of a current doctoral research project investigating how school age piano students respond to a particular approach to practice underpinned by the…

Studies in low-resource settings suggest that multiple aspects of early childhood development are sensitive to the relative poverty of a child's environment. We examined whether direct, quantitative measures of early developing cognitive functions show a similar association with relative poverty. Eye movement latencies were recorded in children at…
