Objective: Childhood maltreatment (CM) is associated with physical health problems throughout the lifespan, yet more research is needed regarding the trajectory of health problems (e.g., onset of health risk indicators) in young adults. The current study examined whether college students self-reporting higher levels of CM exhibited poorer physical…

Objective: In the pathogenesis of acne vulgaris; androgen hormones are mentioned as an important factor for affecting sebaceous gland differentiation. Intrauterine exposure to androgen hormones is associated with autism and autistic features. An important indicator of androgen exposure is the 2D:4D ratio. In this study, we aimed to compare acne…

Studies have identified negative effects of cortisol, a stress hormone, on academic performance. Because natural disasters induce community-wide stress, students who experience natural disasters may subsequently perform worse academically. Our study is the first to examine the immediate effects of close exposure to a natural disaster on academic…

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…

Purpose: The aim of this study was to analyze the association of total leisure noise exposure and hearing threshold shifts over 5 years among adolescents enrolled in the Ohrkan cohort study. Method: The Ohrkan cohort of 2,148 students aged 13-19 years was recruited from 2009 to 2011 and followed up 5 years later. Complete baseline and follow-up…

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…

In response to COVID-19, educators rapidly pivoted to new and innovative ways of delivering lecture material. The ability to host synchronous lectures on platforms like Zoom gave students continued access to classroom material in the face of an ongoing pandemic. The purpose of this study was to investigate the differences in exam scores between…

This study examines stress biomarkers over the process of teaching and their associations with demographics, emotions, and mental health of 56 English as Foreign Language teachers. Participating teachers were invited to complete a questionnaire packet and provide saliva samples over three-time points (i.e., before, during, and end of teaching).…

Objectives: The purposes of this study were to validate the Acoustic Breathiness Index (ABI) for the Japanese-speaking population and to determine whether it is independent of factors such as sex, age, and perceptual ratings of roughness. Method: First, the concurrent validity of the ABI for perceptual breathiness was evaluated on the…

Purpose: Audiology clinics have a need for a nonlinguistic test for assessing speech scores for patients using hearing aids or cochlear implants. One such test, the Spectral-Temporally Modulated Ripple Test Lite for computeRless Measurement (SLRM), has been developed for use in clinics, but it, as well as the related Spectral-Temporally Modulated…

We examined the prospective associations between two indicators of mother-youth emotional climate (i.e., maternal affect, dyadic cohesiveness) during a peer problem discussion and youth coping with peer stress following entry into middle school. We also investigated youth baseline respiratory sinus arrhythmia (RSA) as a moderator of these…

When confronted with an emotion prototype (e.g., loss), individuals may experience not only target emotions (e.g., sadness), but also nontarget emotions (emotions that are atypical or incongruent with an emotion prototype; e.g., gratitude in response to loss). What are the cognitive correlates of nontarget emotions? Drawing from models of emotion…

Adults with intellectual and developmental disabilities (IDD) are at a greater risk of developing high cholesterol and cardiovascular disease. We examined whether physical inactivity, obesity, and diabetes were predictive of reported high cholesterol and whether there were any mediating effects of diabetes on the relationship between obesity and…

The present study examines the relationship between sex, infant temperament, and childhood psychophysiological reactivity via electrodermal activity (EDA). Both temperament and EDA are known to be relatively stable traits across the lifespan reflecting individual reactivity and regulation linked to suboptimal behavioral development and risk for…

Some cognitive abilities exhibit reliable gender differences, with females outperforming males in specific aspects of verbal ability, and males showing an advantage on certain spatial tasks. Among these cognitive gender differences, differences in mental rotation are the most robust, and appear to be present even in infants. A large body of animal…
