People enjoy engaging with music. Live music concerts provide an excellent option to investigate real-world music experiences, and at the same time, use neurophysiological synchrony to assess dynamic engagement. In the current study, we assessed engagement in a live concert setting using synchrony of cardiorespiratory measures, comparing inter-subject, stimulus-response, correlation, and phase coherence. As engagement might be enhanced in a concert setting by seeing musicians perform, we presented audiences with audio-only (AO) and audio-visual (AV) piano performances. Only correlation synchrony measures were above chance level. In comparing time-averaged synchrony across conditions, AV performances evoked a higher inter-subject correlation of heart rate (ISC-HR). However, synchrony averaged across music pieces did not correspond to self-reported engagement. On the other hand, time-resolved analyses show that synchronized deceleration-acceleration heart rate (HR) patterns, typical of an "orienting response" (an index of directed attention), occurred within music pieces at salient events of section boundaries. That is, seeing musicians perform heightened audience engagement at structurally important moments in Western classical music. Overall, we could show that multisensory information shapes dynamic engagement. By comparing different synchrony measures, we further highlight the advantages of time series analysis, specifically ISC-HR, as a robust measure of holistic musical listening experiences in naturalistic concert settings.

Individuals with intellectual disabilities (ID) often exhibit lower levels of physical fitness compared to the general population, including reduced strength, endurance, flexibility, and coordination. Dynamic neuromuscular stabilization (DNS) training can potentially improve the performance of adults with ID caused by weak motor skills due to a lack of desirable nerve growth during childhood and before puberty. Also, DNS training proposed to improve physical fitness in this population, but the effectiveness and durability of DNS training on specific fitness components have not been well-established.

Modeling and analysis of explicit dynamics of foot landing.

The research aims to investigate the mechanical response of footfalls at different velocities to understand the mechanism of heel injury and provide a scientific basis for the prevention and treatment of heel fractures. A three-dimensional solid model of foot drop was constructed using anatomical structures segmented from medical CT scans, including bone, cartilage, ligaments, plantar fascia, and soft tissues, and the impact velocities of the foot were set to be 2 m/s, 4 m/s, 6 m/s, 8 m/s, and 10 m/s. Explicit kinetic analysis methods were used to investigate the mechanical response of the foot landing with different speeds to explore the damage mechanism of heel bone at different impact velocities.

Center for Child Health, Behavior and Development, Seattle Children's Research Institute, 1920 Terry Ave CURE-3, Seattle, WA, 98101, USA.

Purpose: Dynamic eye-tracking paradigms are an engaging and increasingly used method to study social attention in autism. While prior research has focused primarily on younger populations, there is a need for developmentally appropriate tasks for older children.

Methods: This study introduces a novel eye-tracking task designed to assess school-aged children's attention to speakers involved in conversation.

Background: Traditional oral diagnosis education often relies on passive lectures and individual case assessments. Team-based learning (TBL) offers an interactive alternative, but implementation challenges can exist. The 'Case of the Week (COW)' method presents a potentially modified TBL approach for oral diagnosis education.
