Purpose: Muscle groups within the tongue in healthy and diseased populations show different behaviors during speech. Visualizing and quantifying strain patterns of these muscle groups during tongue motion can provide insights into tongue motor control and adaptive behaviors of a patient. Method: We present a pipeline to estimate the strain along…

Our prior research with Indigenous school children and adolescents in Perú, often in remote high-altitude Andean locations, mostly centers on an exploration of health and school performance and their relation to the practice of Transcendental Meditation, a natural and easy-to-learn technique for mental and physiological rest and stress reduction.…

An assessment-related stress is an object of interest of both educational and neurobiological research. In educational literature, "feeling stressed" is measured by self-reports and mostly in the situation of high-stakes examinations before and after an exam. In neurophysiological research, "acute stress" is laboratory observed…

During adolescence, increases in pubertal hormones lead to reproductive maturity as well as changes in cognitive development. Yet, little is known about how to best characterize interindividual differences in hormone concentrations. The goal of the current study was to examine the antecedents and consequences of membership in empirically derived…

Prelingually and profoundly deaf individuals learn to read without complete access to the sounds of language. Nevertheless, many become proficient readers, and the neurocognitive underpinnings of deaf readers' processes differ from those of hearing readers, particularly in orthographic processing. In English, morphological structure is relatively…

Purpose: The objective of the current study was to investigate the short-term test-retest reliability of contralateral suppression (CS) of click-evoked otoacoustic emissions (CEOAEs) using commercially available otoacoustic emission equipment. Method: Twenty-three young normal-hearing subjects were tested. An otoscopic evaluation, admittance…

Purpose: Peak and maximal oxygen uptake (VO[subscript 2peak] and VO[subscript 2max], respectively) are used in assessing aerobic power. For swimmers with physical impairments, it is unclear whether the physiological variables obtained in 200-m and Nx200-m tests are similar. The objective of this study is to assess the validity of VO[subscript…

The YMCA step test uses a prescribed step height which is difficult in a telehealth setting. Examine a modification of the YMCA step test allowing for the use of preexisting in-home objects of variable height as the "step" in a virtual environment. Young healthy participants (n = 40) performed step tests with a small and large object of…

Grounded in the biopsychosocial models of expressive language in autism spectrum disorder (ASD) and fragile X syndrome (FXS), this dissertation included two novel studies that examined the role of biological (i.e., physiology), psychological (i.e., autistic traits, anxiety symptoms, and child affect) and social (i.e., communication partner…

Background: Intelligibility measurement is influenced by the characteristics of a speaker, listener and contextual factors. This study addresses the clinical problem of measuring speech intelligibility in children with velopharyngeal insufficiency (VPI) in real-world conditions. Aims: The purpose of the study was to investigate the effects of…

This study examines how lower secondary school students understand the circulatory system, using the structure-behavior-function (SBF) framework for conceptual representation. It evaluates the progress of students' understanding after interventions with two different teaching approaches, one using a biology textbook supported by augmented reality…

Purpose: Psychoacoustical studies on transmission characteristics related to bone-conducted (BC) speech, perceived by speakers during vocalization, are important for further understanding the relationship between speech production and perception, especially auditory feedback. For exploring how the outer ear part contributes to BC speech…

The aim of this study is twofold: To examine if deafness is invariably associated with deficits in executive function (EF) and to investigate the relationship between sign language proficiency and EF in deaf children of deaf parents with early exposure to a sign language. It is also the first study of EF in children acquiring Polish Sign Language.…

Multiple-choice questions (MCQs) are commonly used in undergraduate introductory science, technology, engineering, and mathematics (STEM) courses, and substantial evidence supports the use of student-created questions to promote learning. However, research on student-created MCQ exams as an assessment method is more limited, and no studies have…

Maximal exercise capacity (W[subscript max]) and anaerobic threshold (A[subscript T]) are important tools used non-invasively to evaluate aerobic fitness levels and clinically possible risk. It has been shown that O[subscript 2] uptake to heartbeat ratio (O[subscript 2] pulse) at the maximal exercise test is an important parameter used to evaluate…
