Synaesthesia is highly prevalent in autism spectrum disorder. We assessed the relation between the degree of autistic traits (Autism Spectrum Quotient, AQ) and the degree of synaesthesia in a neurotypical population, and hypothesized both are related to a local bias in visual perception. A positive correlation between total AQ scores and the…

One common score reported from diagnostic classification assessments is the vector of posterior means of the skill mastery indicators. As with any assessment, it is important to derive and report estimates of the reliability of the reported scores. After reviewing a reliability measure suggested by Templin and Bradshaw, this article suggests three…

Executive function (EF), the set of cognitive processes that govern goal-directed behavior, varies within developmental samples and clinical populations. Here, we perform a conceptual replication of prior work (Dajani et al. in Sci Rep 6:36566, 2016) in an independent sample of typically developing children (n = 183) and children with autism…

Because adolescent life satisfaction is associated with important affective, behavioural and health-related outcomes during both adolescence and later life, strategies for promoting adolescent life satisfaction have potential social value. In the study reported in this article, associations are reported between perceptions of the school climate…

Kim and Opfer (2017) found that number-line estimates increased approximately logarithmically with number when an upper bound (e.g., 100 or 1000) was explicitly marked (bounded condition) and when no upper bound was marked (unbounded condition). Using procedural suggestions from Cohen and Ray (2020), we examined whether this logarithmicity might…

The purpose of the present study was to determine the effectiveness of work rate to heart rate ratio at the estimated anaerobic threshold (A[subscript T]). Thirty male subjects performed an incremental exercise test (15 W/min) until the limit of tolerance was reached. Ventilatory and gas exchange parameters were evaluated breath-by-breath and the…

The relationship between spatial and mathematical ability is controversial. Thus, the current study conducted a meta-analysis of 73 studies, with 263 effect sizes to explore the relationship between spatial and mathematical ability. Furthermore, we explored potential factors that moderate this relationship. Results showed that the relationship…

In this review, findings from studies investigating gender differences in spatial ability, math anxiety, and math achievement, the relationship between spatial ability and math anxiety, between spatial ability and math achievement, and between math anxiety and math achievement are synthesized. As a result of this synthesis, a sequential mediation…

Kim and Opfer (2017) found that number-line estimates increased approximately logarithmically with number when an upper bound (e.g., 100 or 1000) was explicitly marked (bounded condition) and when no upper bound was marked (unbounded condition). Using procedural suggestions from Cohen and Ray (2020), we examined whether this logarithmicity might…

Most student achievement research focuses on four areas: principal tenure, experience, leadership style and school culture. One area needing further research is how the effect of a principal's educational level affects student achievement. Haller (1997) states administrators with a B.A. degree have higher effectiveness scores than principals with…

The purpose of this quantitative, nonexperimental study will be to explore the relationship between stressors and mental health, the impact mental health has on grade point average (GPA), and determine if stressors and mental health moderate GPA for doctoral students during a pandemic. There is evidence that stress impacts mental health and school…

Science education helps individuals understand the events occurring in their environment and the world, starting from their immediate environment. This study aims to determine pre-service preschool teachers' science education self-efficacy and attitudes toward science teaching according to various variables. This research is a descriptive study…

In adolescence, individuals are at high risk for cyberbullying perpetration. Although the role of trait anger in cyberbullying perpetration has attracted attention in the research literature, it is unclear the temporal sequence between trait anger and adolescents' cyberbullying perpetration and whether stressful environments could interact…

With the advent of smartphones and fourth generation mobile technologies, the effect of social media on society has stirred up some debate and researchers across various disciplines have drawn different conclusions. Social media provides university students with a convenient platform to create and share educational content. However, social media…

Pragmatic language impairments are common in neurodevelopmental disorders, especially in autism spectrum disorder (ASD). The relationship between structural language skills and pragmatic competence in children with autistic symptoms, however, is largely unknown. We investigated this relationship based on the Children's Communication Checklist-2…
