Differences and Correlations between Instruction Patterns in Consecutive, Selective Reaction-Time Tests Administered to Early Childhood Participants

Agility is associated with infants’ developing the ability to efficiently shift their center of gravity. Therefore, it is essential to formulate tests that can reliably evaluate young children’s agility development. And continuous jump over tests, simple reaction-time tests and side-step tests are typically used to evaluate children’s agility during early childhood. They can examine agility through the number of movements completed or through simple movement speed. However, during early childhood, daily living involves recognizing danger, moving quickly to avoid it, and repeatedly and accurately altering one’s direction of movement during play. Hence, consecutive and selective reaction-time observations, and not only speed assessments, are essential to evaluate young children’s agility.

In this research, the authors considered the effect of differences between instruction patterns in consecutive, selective reaction-time tests administered to early childhood participants. Participants included 62 young male children (mean age 5.3 ± 0.6 years old, mean height 107.4 ± 5.5 cm, mean mass 17.9 ± 2.2 kg). Starting from a standing position, each participant rapidly moved eight times on a sheet—either left, right, forward, backward, or diagonal—in accordance with the given target. Five different combinations were used; each combination required participants to move in each of the eight possible directions once, including the four diagonal directions.

The results showed that on each pattern, the total times for all participants were added to yield a consecutive, selective reaction time for that pattern. Single-factor dispersion analysis results did not indicate a statistically significant difference in reaction times between the test patterns (the level of significance was determined as 0.05). Furthermore, a greater-than-medium correlation between the five patterns with regard to their total consecutive, selective reaction-times was observed.

Consequently, while no large difference was demonstrated between patterns, a relatively high correlation was observed between patterns on consecutive, selective reaction-time tests administered to young children. It is hypothesized that for evaluating the agility of early childhood, a successive choice reaction test with any pattern is valid.

Incorporation of High-Altitude Balloon Experiment in High School Science Classrooms

High-altitude balloon is a balloon, filled usually with helium or hydrogen that ascends into an area called “near space” or stratosphere. The most common type of high-altitude balloons are weather balloons. Other purposes include use as a platform for experiments in the upper atmosphere. Modern balloons generally contain electronic equipment such as radio transmitters, cameras, or satellite navigation systems, such as GPS receivers. The mission of the High-Altitude Balloon Experiment (HABE) is to acquire supporting data, validate enabling technologies, and resolve critical acquisition, tracking, and pointing (ATP) and fire control issues in support of future space-based precision pointing experiments. The use of high-altitude balloons offers a relatively low-cost, low-vibration test platform, a recoverable and reusable payload, worldwide launch capability, and a 'near- space' emulation of the future space systems operational scenarios. More recently, several university...

Location Optimization of a Coal Power Plant to Balance Costs against Plant’s Emission Exposure

Fuel and its delivery cost comprise the biggest expense in coal power plant operations. Delivery of electricity from generation to consumers requires investment in power lines and transmission grids. Placing a coal power plant or multiple power plants near dense population centers can lower transmission costs. If a coalmine is nearby, transportation costs can also be reduced. However, emissions from coal plants play a key role in worsening health crises in many countries. And coal upon combustion produces CO 2 , SO 2 , NO x , CO, Metallic and Particle Matter (PM10 & PM2.5). The presence of these chemical compounds in the atmosphere in close vicinity to humans, livestock, and agriculture carries detrimental health consequences. The goal of the research was to develop a methodology to minimize the public’s exposure to harmful emissions from coal power plants while maintaining minimal operational costs related to electric distribution losses and coal logistics. The objective was...

Effects of Karate Training on Basic Motor Abilities of Primary School Children

“You never attack first in karate” might be the best conclusion of karate, which is a martial art practiced typically without weapons. It’s reported that karate has a long history for several hundred years, but the modern karate was spread to the whole Japan from Okinawa in the early part of 20th century. Now it has become one of the most widely practiced martial art forms in the world. Usually, it’s divided into Kihon, Kata and Kumite. As for the beginners, Kihon is more suitable for them because it involves basic techniques. Due to karate consists of dynamic offensive and defensive techniques using all parts of the body to their maximum advantage, the best understanding of true karate practice is the perfection of oneself through the perfection of the art. It not only develops coordination, quickens reflexes, and builds stamina, but also develops composure, a clearer thought process, deeper insight into one’s mental capabilities, and more self-confidence. So many researchers stu...
