According to Klahr's (2000, 2005; Klahr & Dunbar, 1988) Scientific Discovery as Dual Search model, inquiry processes require three cognitive components: hypothesis generation, experimentation, and evidence evaluation. The aim of the present study was to investigate (a) when the ability to evaluate perfect covariation, imperfect covariation, and non‐covariation evidence emerges, (b) when experimentation emerges, (c) when hypothesis generation skills emerge, and (d), whether these abilities develop synchronously during childhood. We administered three scientific reasoning tasks referring to the three components to 223 children of five age groups (from age 4.0 to 13.5 years). Our results show that the three cognitive components of domain‐general scientific reasoning emerge asynchronously. The development of domain‐general scientific reasoning begins with the ability to handle unambiguous data, progresses to the interpretation of ambiguous data, and leads to a flexible adaptation of hypotheses according to the sufficiency of evidence. When children understand the relation between the level of ambiguity of evidence and the level of confidence in hypotheses, the ability to differentiate conclusive from inconclusive experiments accompanies this development. Implications of these results for designing science education concepts for young children are briefly discussed.  相似文献

We investigated the effect of culture, moral discourse, and motivation to engage in prosocial behavior on benefactors’ positive affect. Participants from three cultures (Japan, Romania, and the United States) responded to scenarios in which they could perform small acts of kindness for different targets. A stronger relationship between agentic and obligated motivation to perform acts of kindness, as well as between obligated motivation and positive affect, was observed for participants from Japan, and for individuals with higher endorsement of the Community Ethic. Agentic motivation to engage in prosocial behavior was related to benefactors’ positive affect, regardless of relationship type.  相似文献

The current study's aims are twofold: first, we investigate the relationship between employability and both work‐related (engagement) and general (life satisfaction) well‐being. Second, we study how employability may be relevant in times of high job insecurity. Specifically, we hypothesise (1) a positive relationship between employability and employees’ well‐being, (2) a negative relationship between employability and job insecurity, and (3) a negative relationship between job insecurity and employees’ well‐being, so that (4) job insecurity mediates the relationship between employability and employees’ well‐being. Results based on a sample of 559 respondents from divisions of seven Belgian organisations support our hypotheses. We conclude that employability may be a means to secure one's labour market position, rather than a means to cope with job insecurity. Les objectifs de cette étude sont doubles: nous étudions d’abord la relation entre l’employabilité et à la fois le bien‐être relatif au travail (implication) et le bien‐être global (la satisfaction provenant de l’existence). Ensuite, nous nous interrogeons sur la pertinence de l’employabilité en période de grande insécurité professionnelle. Plus précisément, nous posons les hypothèses 1) d’une relation positive entre l’employabilité et le bien‐être des employés, 2) d’une relation négative entre l’employabilité et l’insécurité professionnelle et 3) d’une relation négative entre l’insécurité professionnelle et le bien‐être des salariés, si bien que 4) l’insécurité professionnelle régule la relation entre l’employabilité et le bien‐être des salariés. Les résultats issus d’un échantillon de 559 répondants provenant de départements de sept organisations belges confortent nos hypothèses. On conclut que l’employabilité peut être une façon de sécuriser sa situation sur le marché du travail plutôt qu’un moyen pour affronter l’insécurité professionnelle.  相似文献

Drawing on stress and justice literature, we argue that perceptions of job insecurity induce feelings of low procedural justice, which has immediate and prolonged negative effects on health (depressive symptoms, sleep difficulties). Moreover, we explore whether the strength of the job insecurity–justice relationship differs between individuals as a function of their average level of job insecurity over time. Finally, we explore whether the procedural justice–health relationship differs between individuals as a function of variability in justice perceptions over time. We analyzed Swedish panel data from permanent workers over four consecutive waves (with a two-year time lag between waves) using multilevel analysis, separating within- and between-person variance. Results showed that job insecurity associated negatively with procedural justice at the same time point for all waves. Prolonged effects were less stable. We found immediate (but not prolonged) indirect effects of job insecurity on health outcomes via procedural justice. Average levels in job insecurity over time moderated the within-person job insecurity–justice relationship. However, variability in procedural justice over time did not moderate the within-person justice–health relationship. In conclusion, disentangling within- and between-person variability of job insecurity and justice perceptions contributes to the understanding of health effects.  相似文献
