Background: The purported reciprocity between motivation and academic achievement in education has largely been supported by correlational data. Aims: Our first aim was to determine experimentally whether motivation and achievement are reciprocally related. The second objective was to investigate a potential behavioural mediation pathway between…

Choosing a course of study is one of the most consequential decisions a university student will make. While there is considerable literature investigating how personality influences students' choice of discipline, there is currently no evidence about how students cluster in disciplines relative to their civic-mindedness. This is an important gap…

Normative studies are needed to obtain norms for comparing individuals with the reference population on relevant clinical or educational measures. Norms can be obtained in an efficient way by regressing the test score on relevant predictors, such as age and sex. When several measures are normed with the same sample, a multivariate regression-based…

Teacher professional learning communities (PLCs) have the potential to result in teacher professional development, provided that effective communication takes place during PLC meetings. Building on the perspective of collaborative knowledge building, this study examined teachers' interaction patterns during these meetings. Connections were…

To explore associations between autism traits and family functioning over time, we studied longitudinal data of a mixed group of 168 clinically referred autistic and non-autistic children. Cross-lagged models showed a significant association between fewer autism traits at the diagnostic assessment and better family functioning 1 year later for the…

Camouflaging is hypothesized to play an important role in developing mental health difficulties. But this might not be true for everyone. It remains unclear for whom camouflaging is associated with mental health. In this preregistered study (AsPredicted #45095), we investigated whether (1) camouflaging and mental health were associated and (2) we…

Identity research focuses on multiple processes capturing how adolescents form and maintain a sense of self. However, identity content (the "what" of identity) might impact associations between identity and the association with well-being. We examined this potential role of content (i.e., valence and life domain) in two studies, focusing…

Background and aims: Many children with developmental language disorder (DLD) have difficulties in executive functioning (EF) and theory of mind (ToM). These difficulties might be explained by the theory that children's conceptual understanding changes over five stages of word meaning structure, from concrete and context-dependent to abstract and…

The goal of this study was to advance the conceptualization and measurement of adolescent popularity by exploring the commonly used composite score (popularity minus unpopularity). We used standardized peer nominations from 4,414 early adolescents (ages [approximately equal to] 12-14 years) from three samples collected in two countries. Popularity…

The choice of cortisol sampling times in early childhood studies varies widely. Given that recommendations on sampling protocols are largely based on adults, the present study aimed to broaden current knowledge by examining how reliably cortisol measures obtained at different daytimes would reveal between-individual differences in toddlers'…

Given the influential role of organizational context for creativity, this study examines the cross-level effects of 2 prevalent contextual elements -- HR systems and relational climates -- on individual and team creativity. We have conducted a multilevel multi-source study through hierarchical linear modeling on a sample of 282 employees nested in…

The present study addresses creativity as an employee strategy adopted to deal with challenges and distinguishes between incremental creativity (i.e., minor modifications to existing practices) and radical creativity (i.e., major departures from current practices). We hypothesize that employee self-reported mindfulness and other-rated personal…

In the present study, it was hypothesized that the proportion of open questions teachers ask during shared book reading would be directly and indirectly (through class aggregated mean length of utterance) related to children's vocabulary and would be directly and indirectly (through class aggregated mean length of children's utterance and…

The accuracy of students' relative comprehension judgments when reading texts is typically rather low. This has been ascribed to students grounding their comprehension judgments on cues that are not diagnostic of their actual comprehension level. Asking students to complete causal diagrams--a diagramming scaffold--before judging comprehension has…

This study investigated whether the amount of emergency remote teaching (ERT) was negatively associated with students' academic performance in terms of study delay and explored whether this association was mediated by study-related experiences, i.e. students' education satisfaction and subsequently academic wellbeing (academic burnout and academic…
