To draw valid and reliable conclusions from child studies involving facial expressions, well-controlled and validated (child) facial stimuli are necessary. The current study is the first to validate the facial emotional expressions of child models in school-aged children. In this study, we validated the Radboud Faces Database child models in a…

Few studies have used exploratory factor analysis (EFA) and exploratory bifactor factor analysis (EBFA) to define a baseline factor structure model checking the construct-relevant psychometric multidimensionality of student engagement. This study was conducted on a sample of 3,374 students in France, Wallonia-Brussels Federation, and Luxembourg by…

Intentional self-regulation (ISR) undergoes significant development across the life span. However, our understanding of ISR's development and function remains incomplete, in part because the field's conceptualization and measurement of ISR vary greatly. A key sample case involves how Baltes and colleagues' Selection, Optimization,…

The secure-base phenomenon is central to the Bowlby/Ainsworth theory of attachment and is also central to the assessment of attachment across the lifespan. The present study tested whether mothers' knowledge about the secure-base phenomenon, as assessed using a recently designed wordlist prompt measure for eliciting attachment-relevant stories,…

Reviews two models of thinking and intellectual development: Scandura's deterministic model of structuralistic learning, and a generalization of Rasch's probabilistic latent trait model. Models are compared by means of two experiments with balance scale tasks. (RH)

On the basis of a study involving 40 first-grade students, compares Pascual-Leone's and Keating and Bobbitt's developmental theories of information processing by contrasting their predictions about a classification task. Results falsified Keating and Bobbitt's model. Predictions from Pascual-Leone's theory were almost wholly confirmed. (RH)
