Purpose: The goal of this study was to establish the perceptual underpinnings of the terms that are commonly used by patients when describing the quality of their tinnitus. Method: Using a free-classification method, 15 subjects with normal hearing placed 60 different tinnitus-like sounds into similarity clusters on a grid. Multidimensional…

Purpose: Dysphagia is a serious extra pulmonary manifestation of chronic obstructive pulmonary disease (COPD). However, the nature of abnormalities in swallowing physiology in COPD has yet to be clearly established. We explored the frequency of swallowing measures outside the healthy reference range in adults with COPD. Method: Participants were…

Purpose: This study attempts to gain insights into the role of daily voice use in the etiology and pathophysiology of phonotraumatic vocal hyperfunction (PVH) by applying a logistic regression-based daily phonotrauma index (DPI) to predict group-based improvements in patients with PVH after laryngeal surgery and/or postsurgical voice therapy.…

Learning physiology is challenging for students. The nature of the discipline, which includes many complex mechanisms, makes the subject complicated. Furthermore, the length of the textbooks and the usual multiple-choice tests, which prioritize memorizing instead of understanding, tend to discourage the students. Therefore, different pedagogical…

The increasingly severe school violence has become an influential and notorious worldwide problem. The attribution of school violence determines the formulation of coping strategies. Unlike the analysis of family, psychological and social factors, long-term front-line work and follow-up studies have found that student violence's physiological…

Objective: To identify the effects of guided mindfulness meditation on anxiety and stress in pre-healthcare college students. Participants: Students (n = 33, age 19-22 years) were tested between September and November of 2017. Methods: Students completed 5-12 minutes of meditation 6 days/week for 8 weeks. We examined differences in pre- and…

Despite identical learning experiences, individuals differ in the memory formed of those experiences. Molecular mechanisms that control the neurophysiological bases of long-term memory formation might control how precisely the memory formed reflects the actually perceived experience. Memory formed with sensory specificity determines its utility…

Many sports demand high forces at high movement speeds. Joint power combines these two measures and is frequently analyzed by isokinetic tests. However, various concepts of assessing joint power lead to conflicting results. The aim was to examine different methods to calculate peak power during isokinetic knee tests of sixty-one healthy male…

Purpose: The purpose of this study was to review quality benchmarks from hearing screening programs conducted at local Head Start centers and preschool and elementary schools associated with our university training programs. Method: Hearing screening results from 6,043 children were reviewed. Hearing screening was accomplished using either…

Gastrointestinal (GI) dysfunction is a common comorbidity of autism spectrum disorders (ASD) and is associated with increased severity of characteristic autism-associated symptoms. However, the underlying biological mechanisms for GI dysfunction symptoms in children with ASD are unknown. This review explores potential explanations for these…

Community college students come from a variety of backgrounds and have different levels of educational preparedness compared to undergraduates in 4-year undergraduate schools. Historically, retention rates of these students in human physiology courses have been low, often due to non-passing grades. Incorporation of additional active learning…

Autism spectrum disorder (ASD) is a complex neurological and developmental disorder, and a growing body of literature suggests the presence of autonomic nervous system (ANS) dysfunction in individuals with ASD. ANS is part of the "gut brain axis", which consists of an intricate interplay between the gut microbiome, mucosal immune system,…

It is unclear if the transition from traditional, in-person physiology laboratories to virtual alternatives has educational impacts on students. This study used a systematic review to critically evaluate research papers that investigated the effectiveness of virtual physiology laboratories for student learning. Eleven studies, retrieved from the…

We often say food and fuels "contain" energy. It is more accurate to say that energy is stored in the "fuel-oxygen system" generated during photosynthesis. It is definitely "not" stored in fuels or food (except for the very small amount of energy that can be obtained during anaerobic respiration). Aerobic respiration…

Education in science, technology, engineering, and math (STEM) is increasingly online, even the laboratory components of STEM courses. As online laboratory education trends upward in terms of enrollment and variety of course offerings, the central question remains: Is online equivalent to a traditional face-to-face (F2F) lab experience? In this…
