Video Game–Based Exercise, Latino Children's Physical Health, and Academic Achievement

BackgroundThere is a paucity of research investigating the effects of innovative physical activity programs on physical health and academic performance in the Latino population.PurposeTo examine the impact of Dance Dance Revolution [DDR]–based exercise on Latino children's physical fitness and academic achievement.DesignA repeated-measures crossover design was used. In Year 1, Grade-4 students were assigned to the intervention group and offered 30 minutes of exercise (DDR, aerobic dance) three times per week. Grade-3 and Grade-5 students made up the comparison group and were offered no structured exercise at school. In Year 2, the Grade-4 students were again assigned to the intervention, whereas Grade-5 and Grade-6 students were in the comparison group.Setting/participantsAssessments were conducted with 208 Latino school children.Main outcome measuresThe baseline measures included time to complete a 1-mile run, BMI, and reading and math scores. Data were collected again 9 months later. Overall, data were collected in 2009–2011 and analyzed in 2012.ResultsData yielded significant differences between the intervention and comparison groups in differences in 1-mile run and math scores in Year 1 and Year 2. The results also revealed net differences in the intervention versus comparison group scores on the 1-mile run for Grade 3 (p<0.01). Additionally, children's yearly pre-test and post-test BMI group changes differed (χ2(2)=6.6, p<0.05) only for the first year of intervention.ConclusionsThe DDR-based exercise intervention improved children's cardiorespiratory endurance and math scores over time. Professionals should consider integrating exergaming at schools to achieve the goals of promoting a physically active lifestyle and enhancing academic success among Latino children

The impact of temporal synchronisation imprecision on TRF analyses

Human sensory perception requires our brains to extract, encode, and process multiple properties of the sensory input. In the context of continuous sensory signals, such as speech and music, the measured electrical neural activity synchronises to properties such as the acoustic envelope, a phenomenon referred to as neural tracking. The ability of measuring neural tracking with non-invasive neurophysiology constitutes an exciting new opportunity for applied research. For example, it enables the objective assessment of cognitive functions in challenging cohorts and environments by using pleasant, everyday tasks, such as watching videos. However, neural tracking has been mostly studied in controlled, laboratory environments guaranteeing precise synchronisation between the neural signal and the corresponding labels (e.g., speech envelope). There exist various challenges that could impact such a temporal precision in, for instance, out-of-lab scenarios, such as technology (e.g., wireless data acquisition), mobility requirements (e.g., clinical scenarios), and the task (e.g., imagery). Aiming to address this type of challenge, we focus on the predominant scenario of continuous sensory experiments involving listening to speech and music. First a temporal response function analysis is presented on two different datasets to assess the impact of trigger imprecision. Second, a proof-of-concept re-alignment methodology is proposed to determine potential issues with the temporal synchronisation. Finally, a use-case study is presented that demonstrates neural tracking measurements in a challenging scenario involving older individuals with neurocognitive decline in care homes. Significance Statement Human cognitive functions can be studied by measuring neural tracking with non-invasive neurophysiology as participants perform pleasant, everyday tasks, such as listening to music. However, while recent work has encouraged the use of this approach in applied research, it remains unclear how robust neural tracking measurements can be when considering the methodological constraints of applied scenarios. This study determines the impact of a key factor for the measurement of neural tracking: the temporal precision of the neural recording. The results provide clear guidelines for future research, indicating what level of imprecision can be tolerated for measuring neural tracking with speech and music listening tasks in both laboratory and applied settings. Furthermore, the study provides a strategy to assess the impact of imprecision in the synchronisation of the neural recording, thus developing new tools for applied neuroscience

Autism Spectrum Disorder Screening Practices in the United States and Mexico

Purpose: The purpose of this study was to explore screening practices for autism spectrum disorder (ASD) in Mexico and the United States (U.S.). Methods: Data from a larger study exploring the knowledge, screening, and diagnostic practices of healthcare practitioners from Mexico and the U.S. was used for the current study. The original survey was created by experts in ASD and consisted of 63 questions: 15 demographic questions, 20 questions relating to knowledge of ASD, 11 questions relating to screening practices, and 17 questions relating to diagnostic practices. All surveys were completed by professionals engaging in the screening and diagnosis of ASD. For this study, a total of thirty- five survey responses for the screening portion of the survey (30 from the U.S. and 5 from Mexico) were explored. Qualitative data and descriptive statistics were utilized. Results: Many of the responses relating to screening practices from professionals practicing in Mexico and the U.S. were consistent with best practice guidelines from the Centers for Disease Control and Prevention (CDC), the American Academy of Pediatrics (AAP), and the Mexican Public Health Guide. Furthermore, many similarities were found in the screening practices of professionals from both countries. Differences in screening practices reported by professionals from Mexico and the U.S. were found in the type of professional involved in the screening process and professional referrals after a failed ASD screening. Additionally, some professionals from both the U.S. and Mexico reported the use of inappropriate screening tools, and the average age reportedly screened was much higher than the current recommendations of the American Academy of Pediatrics (Hyman et al., 2020). Conclusion: An understanding of the screening practices currently being used in Mexico and the U.S. provides both researchers and clinicians with a better understanding of what is being implemented by different professionals. This study identified areas of strength and areas of weaknesses in the screening process for ASD in both countries. These results can now be used in future studies and programs targeting improved screening processes in Mexico in the U.S. Improved screening processes are important because of the potential to result in an earlier age of diagnosis of ASD and provision of services at a younger age. The latter of which is associated with better outcomes for children with ASD

Effect of Daily Fluctuations from Flaming Gorge Dam on Ice Processes in the Green River

This report provides results and conclusions of a detailed investigation of ice processes in the main channel of the reach of the Green River between the downstream end of Split Mountain (River Mile [RM1] 320) and the Ouray, Utah Bridge (R.M248). The objective of the study was to examine the influence of daily fluctuations in water releases from Flaming Gorge Damon river ice processes in this reach, which serves as an overwintering area for endangered Colorado pikeminnow and razorback sucker. The objective of the study was met through examination of historical records of winter water and air temperatures, flow measurements, and ice observations; through measurements of differences in ice conditions under steady and fluctuating flow regimes; and through calibration and use of an ice process model to compare hydraulic and ice conditions expected under steady and fluctuating flow regimes
