Previous research has attempted to understand why countries with relatively favorable conditions and high estimated average IQs (such as Finland and Japan) have a relatively low per capita number of scientific Nobel prizes. In the present study, we examine whether there is a relationship between national schizophrenia and left-handedness…

Intentional teaching practices of early childhood education and care (ECEC) educators have a profound influence on children's learning and health. The aim of this study was to assess the relationship between educator intentionality and pre-schoolers physical activity. Objectively measured physical activity (Actigraphs) was measured on 225…

This paper focuses on the emergence of abstraction through the use of a new kind of motion detector--WiiGraph--with 11-year-old children. In the selected episodes, the children used this motion detector to create three simultaneous graphs of position vs. time: two graphs for the motion of each hand and a third one corresponding to their…

The widely and internationally replicated socioeconomic status (SES) gradient of executive function (EF) implies that intervention approaches may do well to extrapolate conditions and practices from contexts that generate better child outcomes (in this case, higher SES circumstances) and translate these to contexts with comparatively poorer…

This study aims to create learning path navigation for target learners by discovering the correlation among micro-learning units. In this study, the learning path is defined as a sequence of learning units used to realize a learning goal, and a period used for realizing the learning goal is regarded as a learning cycle. Furthermore, the learning…

When the relationship between two physical variables, such as voltage and current, can be expressed as y = bx where b is a constant. b may be estimated by least squares, or by averaging the values of b obtained for each x-y data pair. We show for data gathered in an experiment, as well as through Monte Carlo simulation and mathematical analysis,…

Toddlers' understanding of object rotation was investigated using a multimethod approach. Participants were 44 toddlers between 22 and 38 months of age. In an eye-tracking task, they observed a shape that rotated and disappeared briefly behind an occluder. In an object-fitting task, they rotated wooden blocks and fit them through apertures.…

The current study aims to investigate the relationship among problem solving, hope, and self-efficacy and to test a model for determining the role of self-efficacy in the relationship between problem solving and hope. It adopted convenience sampling and consisted of 494 undergraduate students (369 females; 125 males). The Hope Scale, General…

Working memory (WM), the capacity for short-term storage of small quantities of information for immediate use, is thought to depend on activity within the prefrontal cortex. Recent evidence indicates that the prefrontal neuronal activity supporting WM is driven by thalamocortical connections arising in mediodorsal thalamus (mdThal). However, the…

This systematic review explores psychometric properties of the Substance Abuse Subtle Screening Inventory adult version (SASSI-3), the most commonly used instrument by counselors for assessment and diagnosis of alcohol and substance use.

Background: Suicidal ideation, an important risk factor for suicide, is strongly associated with substance use. Factors such as family cohesion, connection with friends, and social support can be protective against suicidal behaviors. The purpose of this study was to explore the association between suicidal ideation, substance use, and resiliency…

Children with autism spectrum disorder (ASD) experience more frequent bullying victimization compared to their neurotypical peers. This study used the 2011 Survey of Pathways to Diagnosis and Services to examine associations between six Children's Social Behavior Questionnaire (CSBQ) subscales and bullying victimization among 1057 children with…

Purpose: Language difficulties are prevalent among children born preterm. Existing studies have largely used standardized language tests, providing limited scope for detailed descriptive examination of preterm language. This study aimed to examine differences in conversational language between children born < 30 weeks and at term as well as…

Background: Perception of exertion is essential for self-regulation in sports. The ability to rate perceived exertion (RPE) is regarded as psychophysiological competence, although cognitive components of RPE are largely unknown. The present study tested the hypothesis that cognitive processing speed, perseveration and figural fluency correlate…

Psychopathology is prevalent in Williams (WS), fragile X (FXS) and Prader-Willi (PWS) syndromes. However, little is known about the potential correlates of psychopathology in these groups. A questionnaire study was completed by 111 caregivers of individuals with WS (n = 35); FXS (n = 50) and PWS (n = 26). Mean age was 26 years (range 12-57 years);…
