This article evaluates the impact of an Art-based program, which consisted in bringing artist to do workshops in public schools, on academic achievements, creativity (i.e., the skill) and the external manifestation of creativity in action (i.e., creative behaviors). The main contribution with respect to previous literature is a quasi-experimental…

Determining the number of factors in exploratory factor analysis is arguably the most crucial decision a researcher faces when conducting the analysis. While several simulation studies exist that compare various so-called factor retention criteria under different data conditions, little is known about the impact of missing data on this process.…

Motivation, stress, and satisfaction are all key elements in academic success. Academic motivation is linked with positive outcomes, such as low levels of stress, high satisfaction, and mental well-being. Although it is well documented that motivational orientation, stress, and satisfaction are closely related together, very little attention has…

Purpose: This study was designed to answer three questions: (a) Does percentage of syllables stuttered (%SS) differ between standard and challenge phone calls; (b) Does anxiety differ between standard and challenge phone calls; and (c) Is there a relationship between %SS and anxiety during standard and challenge phone calls? Method: Participants…

Bayesian methods seem a natural choice for combining sources of evidence in meta-analyses. However, in practice, their sensitivity to the choice of prior distribution is much less attractive, particularly for parameters describing heterogeneity. A recent non-Bayesian approach to fixed-effects meta-analysis provides novel ways to think about…

The current analysis investigates genetic and environmental influences on the bidirectional relationships between temperament and general cognitive ability (GCA). Measures of GCA and three temperament factors (persistence, approach, and reactivity) were collected from 486 children ages 4-9 years (80% white, 50% female) from the Louisville Twin…

This study examined the influence of marital communication on the family stability of married teachers in the Nsukka Education Zone of Enugu State. It was guided by two research questions and two hypotheses. The population comprised 1688 married teachers in Nsukka Education Zone secondary schools. A correlation design was adopted for the study.…

It is widely assumed that subliminal word priming is case insensitive and that a short SOA (< 100 ms) is required to observe any effects. Here we attempted to replicate results from an influential study with the inclusion of a longer SOA to re-examine these assumptions. Participants performed a semantic categorisation task on visible word…

Deciding what items to restudy is an important aspect of self-regulated learning. Previous research (Robey et al. "Psychological Science," 28(11), 1683-1693, 2017) reports that having learners make different types of metacognitive judgments affects restudy decisions. More specifically, when learners made retrospective confidence…

Background: Previous research suggests a relationship between teacher behaviors and students' effort. However, it is not clear what role the students' expectations (i.e., importance of teacher behaviors) play in this relationship. Objective: Utilizing the teacher behavior checklist, this study sought to investigate whether teacher behaviors…

Associations between age, resting-state (RS) peak-alpha-frequency (PAF = frequency showing largest amplitude alpha activity), and thalamic volume (thalamus thought to modulate alpha activity) were examined to understand differences in RS alpha activity between children with autism spectrum disorder (ASD) and typically-developing children (TDC)…

When reasoning about science studies, people often make causal theory errors by inferring or accepting a causal claim based on correlational evidence. While humans naturally think in terms of causal relationships, reasoning about science findings requires understanding how evidence supports--or fails to support--a causal claim. This study…

Background: Although competitive integrated employment (CIE) has been established as a goal of employment research, policy, and practice for individuals with intellectual and developmental disabilities, the secondary benefits of CIE are rarely discussed. Aims: The purpose of this systematic review was to analyze and synthesise research related to…

This formative study attempted to gather evidence for a theory postulating that inclusive education for students with disabilities is best facilitated by teachers with a strong sense of social justice. This theory was investigated by examining the connection between measures of perception of social justice and attitudes toward inclusive education…

The main aim of this study was to (a) test the construct validity of complex problem solving (CPS); (b) examine the ability to acquire knowledge as a mediator of the relationship between intelligence and CPS performance; and (c) investigate the personal need for structure as a moderator of the relationship between intelligence and knowledge…
