The detection of differential item functioning (DIF) is important in psychological and behavioral sciences. Standard DIF detection methods perform an item-by-item test iteratively, often assuming that all items except the one under investigation are DIF-free. This article proposes a Bayesian adaptive Lasso method to detect DIF in graded response…

Self-determination, as a person dispositional characteristic, is indeed influenced by situational characteristics that shape actions across contexts. Research has also reported differences in self-determination as a function of personal factors, but there is a need to integrate this knowledge in a general model aiming to analyse the impact of…

This study shows that residual variation can cause problems related to scaling in exponential random graph models (ERGM). Residual variation is likely to exist when there are unmeasured variables in a model--even those uncorrelated with other predictors--or when the logistic form of the model is inappropriate. As a consequence, coefficients cannot…

The effects of family adverse childhood experiences (ACEs) on timing of ASD diagnoses and receipt of therapies were measured using data from the 2011-2012 National Survey of Children's Health. Parametric accelerated failure time models estimated the relationship between family ACEs and both timing of ASD diagnosis and receipt of therapies among US…

Many interventions are characterized by repeated observations on the same individuals (e.g., baseline, mid-intervention, two to three post-intervention observations), which offer the opportunity to consider differences in how individuals vary over time. Effective interventions may not be limited to changing means, but instead may also include…

The ability to mentally re-experience past events improves significantly from childhood to young adulthood; however, the mechanisms underlying this ability remain poorly understood, partially because different tasks are used across the lifespan. This study was designed to address this gap by assessing the development of event-related potential…

There is considerable variability in the extent to which young people with developmental language disorder (DLD) experience mental health difficulties. What drives these individual differences remains unclear. In the current article, data from the Twin Early Development Study were used to investigate the genetic and environmental influences on…

Longitudinal data from a large sample of twins participating in the Netherlands Twin Register (n = 42,827, age range 3-16) were analyzed to investigate the genetic and environmental contributions to childhood aggression. Genetic auto-regressive (simplex) models were used to assess whether the same genes are involved or whether new genes come into…

We investigated the effects of seeing the instructor's (i.e., the model's) face in video modeling examples on students' attention and their learning outcomes. Research with university students suggested that the model's face attracts students' attention away from what the model is doing, but this did not hamper learning. We aimed to investigate…

Nonacademic skills related to college and career readiness (CCR) have become more prevalent in the literature as proposed conceptual models and frameworks, yet little empirical research exists in their support. We employed latent variable modeling to empirically test a previously proposed six-domain framework of CCR for adolescents with and…

The article describes the relevant aspects of the adolescents' cultural practices in children's summer camp, taking into account their specific characteristics. The summer camp is considered as an educational formation and holistic socio-pedagogical body, designed to create conditions for the development of the person. The criteria for inclusion…

In previous studies, older as compared with younger individuals were more strongly motivated to regulate their momentary affect toward pleasant and calm states. Whether these motivational differences are also reflected in regulatory behavior and whether this behavior is efficient in terms of affect change, however, is unclear. To address these…

The dual route model (DRM) of reading suggests two routes of reading development: the phonological and the orthographic routes. It was proposed that although the two routes are active in the process of reading; the first is more involved at the initial stages of reading acquisition, whereas the latter needs more reading training to mature. A…

The aim of this research was to establish whether gender and age have an impact on spatial reasoning and its development through the use of 3D modeling. The study was conducted on a sample of 196 children from sixth to ninth grade, of whom 95 represented the experimental group and 101 the control group. The experimental group received 3D modeling…

Objectives: Teacher connectedness is an important factor for young people's well-being. The aim of this paper was to examine teacher connectedness in detail and its potential association with emotional wellbeing. More specifically, we set out to analyse whether teacher connectedness acted as a universal asset for boys and girls of different ages…
