Repetition without Repetition or Differential Learning of Multiple Techniques in Volleyball?

2021

A variety of approaches have been proposed for teaching several volleyball techniques to beginners, ranging from general ball familiarization to model-oriented repetition to highly variable learning. This study compared the effects of acquiring three volleyball techniques in parallel with three approaches. Female secondary school students (N = 42

Post-orthodontic position of lower incisors and gingival recession: A retrospective study

2017

Background To evaluate if changes in lower incisor position following orthodontic treatment are correlated with development of gingival recessions. Material and methods Pre- and post-treatment digital models and lateral cephalograms of 22 subjects were collected retrospectively. The clinical crown length, gingival scallop, and papilla height of the central lower incisor were measured along with the cephalometric incisor's inclination, the distance from the mandibular plane, and the distance between the Infradentale and Menton points. Statistical correlations between gingival and cephalometric variables were studied. In addition, two groups were defined based on the post-treatment incisor in…

Hemispheric Differences in Functional Interactions Between the Dorsal Lateral Prefrontal Cortex and Ipsilateral Motor Cortex

2020

Background: The dorsolateral prefrontal cortex (DLPFC) in both hemispheres have a central integrative function for motor control and behavior. Understanding the hemispheric difference between DLPFC and ipsilateral motor cortex connection in the resting-state will provide fundamental knowledge to explain the different roles DLPFC plays in motor behavior. Purpose: The current study tested the interactions between the ipsilateral DLPFC and the primary motor cortex (M1) in each hemisphere at rest. We hypothesized that left DLPFC has a greater inhibitory effect on the ipsilateral M1 compared to the right DLPFC. Methods: Fourteen right-handed subjects were tested in a dual-coil paired-pulse parad…

A Unified Theory of Psychophysical Laws in Auditory Intensity Perception.

2020

Psychophysical laws quantitatively relate perceptual magnitude to stimulus intensity. While most people have accepted Stevens's power function as the psychophysical law, few believe in Fechner's original idea using just-noticeable-differences (jnd) as a constant perceptual unit to educe psychophysical laws. Here I present a unified theory in hearing, starting with a general form of Zwislocki's loudness function (1965) to derive a general form of Brentano's law. I will arrive at a general form of the loudness-jnd relationship that unifies previous loudness-jnd theories. Specifically, the "slope," "proportional-jnd," and "equal-loudness, equal-jnd" theories, are three additive terms in the ne…

Gender, Age, and Generational Differences in the Use Intention of Mobile Payments and Its Antecedents

2022

Although mobile payments have gained considerable attention in academic research, there still are major gaps in our more in-depth understanding of the antecedents of their acceptance and use. In this study, we aim to address these gaps by examining the potential gender and age differences in the use intention of mobile payments and its antecedents in terms of the effects of the antecedent factors on use intention as well as the antecedent factors and use intention themselves while also considering the critical prerequisite of measurement invariance. Moreover, through a careful selection of the compared age groups, we extend the examination to cover also the potential generational difference…

Gender differences in usage and user experience of Oiva App

2015

Previous research has indicated that gender is an important demographic to consider when designing effective and tailored technology interventions. Despite this need, gender differences is still an understudied topic in the field of technology interventions. The objective of this study was to study gender differences in usage and user experience of a mental wellness app called Oiva. Gender differences in the app’s effect on the participants’ mental well-being were also investigated. Oiva is a stand-alone mental wellness app that aims to increase its users’ psychological flexibility by teaching Acceptance and Commitment Therapy (ACT) based skills. The study population of the current study wa…

Spatial Cognition 2020/1: Book of abstracts : August 2-4, 2021, University of Latvia

2021

Spatial Cognition is concerned with the acquisition, development, representation, organization, and use of knowledge about spatial objects in real, virtual or hybrid environments and processed by human or artificial agents. Spatial Cognition includes research from different fields insofar as they are concerned with cognitive agents and space, such as cognitive and developmental psychology, linguistics, computer science, geography, cartography, philosophy, neuroscience, and education. Research issues in the field range from the investigation of human spatial cognition to mobile robot navigation, including topics such as wayfinding, spatial planning, spatial learning, internal and external re…

Mechanical activity of small and large intestine in normal and mdx mice: a comparative analysis.

1999

The aim of this study was to compare the motor pattern (recorded as changes in intraluminal pressure) of isolated duodenum and proximal colon between dystrophic mdx and normal mice. When duodenal recordings from control preparations were compared with mdx mice there was no significant difference in the spontaneous motor pattern, responses to electrical nerve stimulation or sensitivity to pharmacological agents. Colonic segments from mdx mice showed a more complex motor pattern, consisting of contractions with amplitude and frequency similar to those of controls and by additional contractions with lower amplitude and higher frequency. Moreover, 70% of the colonic preparations from mdx mice d…
