Physiological synchrony, or concordance, among caregiver-child dyads involves the matching of biological states. Understanding this process is critical for enhancing our knowledge of the ways that the caregiver-child relationship supports child development. However, the meaning of physiological synchrony for child adjustment is poorly understood.…

An understanding of human embryology is essential for students to better understand the subjects of human anatomy and physiology. However, human embryology is a challenging subject for many, since they must learn how anatomic structures and physiological processes develop over a period of time. Embryology texts typically use static,…

Results from recent research have demonstrated positive effects of somatic approaches, such as the Feldenkrais Method, somaesthetics, and body mapping in the field of music. However, the direct impact of such approaches on instrumental sound has not been studied so far. The present pilot study was thus designed to investigate the influence of…

Aim: This study aimed to investigate the impact of a group-based autogenic training (AT) relaxation intervention on levels of anxiety in adolescents in mainstream school settings. Method: A mixed-methods design was used to measure differences in levels of anxiety and explore a range of perceived changes between groups over time. Sixty-six young…

While age effects in reaction time (RT) tasks across the lifespan are well established for level of performance, analogous findings have started appearing also for indicators of intra-individual variability (IIV). Children are not only slower, but also display more variability than younger adults in RT. Yet, little is known about potential…

Purpose: This study aimed to compare the energy expenditure and intensity of active video games to that of treadmill walking in children and adolescents. Method: Seventy-two boys and girls (aged 8-13 years) were recruited from local public schools. Energy expenditure and heart rate were measured during rest, during 3-km/hr, 4-km/hr, and 5-km/hr…

Stress influences how we remember emotional events and how these events shape future behaviors. However, the impact of stress on memory specificity for emotional events has yet to be examined. To this end, the present study utilized a mnemonic discrimination task that taxes hippocampal pattern separation, the process of distinguishing between…

The purpose of the study was to establish the vitamin-mineral status of children with autism spectrum disorders (ASD) who exhibit attention-deficit/hyperactivity disorder (ADHD). Four research questions were formulated for the study. A quasi-experimental of ex post facto research design was used. The study was conducted in four special schools and…

Low arousal states (especially boredom) have been shown to be more deleterious to learning than high arousal states, though the latter have received much more attention (e.g., test anxiety, confusion, and frustration). Aiming at profiling arousal in the classroom (how active students are) and examining how activation levels relate to achievement,…

This experimental study examined the validity of 3 underlying mechanisms that have been proposed in the research literature to explain the anxiety-reducing effect of coloring mandalas: distraction, structure, and centering. Four conditions were tested: (a) freely coloring a mandala, (b) coloring a mandala with preset colors, (c) freely drawing a…

The main purpose of this study was prediction of elite male trampolines performance based on the selected physical capabilities in different age categories. To this aim, 45 male athletes (age 14.17 ± 2.86 yrs, athletic experience 7.22 ± 3.64 yrs and competitive experience 3.31 ± 2.44 yrs), who participated in the national trampoline team's…

The purpose of this study was to establish a set of normative data (growth curve and centiles) for the Infant Monitor of vocal Production (IMP) using a representative population of infants with typically developing hearing. A linear mixed effect model and regression was used to derive 'stage-for-age' trajectory and growth centiles from the…

Evolution can be a difficult concept for students, even though it is an organizing principle in biology. It can also be a challenge for teachers to cover evolution properly (or at all) in the classroom, whether due to personal attitudes or lack of knowledge or confidence in the material (Rutledge and Mitchell 2002). Even in some states where…

Purpose: This study investigates how the variables of culture and hearing status might influence the amount of parent-child talk families engage in throughout an average day. Method: Seventeen Vietnamese and 8 Canadian families of children with hearing loss and 17 Vietnamese and 13 Canadian families with typically hearing children between the ages…

To facilitate learning advanced instrumental techniques, essential tools for visualizing biomaterials, a simple and versatile laboratory exercise demonstrating the use of Atomic Force Microscopy (AFM) in biomedical applications was developed. In this experiment, the morphology of heat-denatured and amyloid-type aggregates formed from a low-cost…
