A reliable measure is one we can trust in the long run. Thus, the reliability of measurements is as important as their validity. Here we investigated the reliability of brain electrical visual evoked responses to faces and noise textures. For the first time, we provide reliability measures for the full time course of event-related potentials (ERPs). Our analyses were also performed on a R(2)(t)...

The purpose of this study was to establish validity and reliability evidence for the medicine ball throw test for kindergarten students, an underrepresented group in the literature. The subjects were 105 students, 5-7 years old, BMI 17.44 +/- 3.17 kg x m(-2), 43% female and 57% male. Intraclass correlation coefficients (ICCs) were used to examine reliability, and Pearson correlation coefficient...

A stimulus is a reliable signal of an outcome when the probability that the outcome occurs in its presence is different from in its absence. Reliable signals of important outcomes are responsible for triggering critical anticipatory or preparatory behavior, which is any form of behavior that prepares the organism to receive a biologically significant event. Previous research has shown that huma...

Eyewitness memory is widely believed to be unreliable because (a) high-confidence eyewitness misidentifications played a role in over 70% of the now more than 300 DNA exonerations of wrongfully convicted men and women, (b) forensically relevant laboratory studies have often reported a weak relationship between eyewitness confidence and accuracy, and (c) memory is sufficiently malleable that, no...

In wireless networks, low-power Zigbee is an excellent network solution for wireless medical monitoring systems. Medical monitoring generally involves transmission of a large amount of data and easily causes bottleneck problems. Although Zigbee's AODV mesh routing provides extensible multi-hop data transmission to extend network coverage, it originally does not, and needs to support some form o...

In the manufacturing industry, product quality has become a key factor in determining a firm’s success or failure in the global marketplace. Advanced, highly reliable manufacturing methods have made it possible to achieve very high standards of product quality. As a result, more and more firms are making product quality a keystone of their competitive strategy. However, the improvement of produ...

Previous studies of visual processing in humans using event-related potentials (ERPs) have demonstrated that task-related modulations of an early component called the "N1" wave (140-200 ms) reflect the operation of a voluntary discrimination process. Specifically, this component is larger in tasks requiring target discrimination than in tasks requiring simple detection. The present study was de...

Two instruments were developed and standardized on first-, second-, and third-grade boys and girls. The Toy Preference Test (TPT) measures sex-role preference, and/or Stereotypic Sex-Role Concepts of masculinity (SRCm) and femininity (SRCf), depending upon the instructions used for administration. The Rating Scale for Children (RSC) taps sex-role adoption. Subjects were at least third generatio...

nowadays, new technologies have changed the methods of serving customers in many service organizations. service in the banking industry has been influenced by international communication technology (ict) developments in essential ways. nowadays the importance of websites and their unique features in provision of services to customers is increasing. however, traditional methods of banking with d...
