小学高年级学生创造力的发展:性别差异及学校支持的作用

Subjects: Psychology >> Developmental Psychology

创造力被视为青少年在日新月异的环境中胜出的核心能力。发展心理学家付出了巨大的努力去研究创造力的发展,但一直没有达成共识。研究者们发现影响创造力发展的因素有许多,其中包括个体差异(例如性别差异)和成长过程中的学校环境。此外,这些研究并没有从初始水平和发展速度两个方面细致地刻画创造力的发展轨迹。本研究综合以上这些可能影响创造力发展的因素,针对已有研究的不足,设计了一个纵向研究,以考察小学高年级学生创造力的发展轨迹,以及从个体间水平上分析性别、学校支持(包括教师支持和同伴支持)对小学高年级学生创造力发展轨迹的影响,并从个体内水平上分析学校支持的变化是否带来创造力的发展的变化。 来自三所小学的203名4年级小学生(109名男孩和94名女孩,平均年龄= 10.43岁,SD = 0.62岁,在测试的第一阶段,T1)参加了为期三年的纵向研究,以及被评估了三次(T1,T2,T3)。 Runco Creativity Assessment Battery(来自rCAB的图形发散思维测验)和Perceived School Climate Scale 分别用于测量创造力和学校支持。 该研究项目经过Ethics Committee of Shandong Normal University的审查批准,并获得参加者父母的知情同意。本研究使用SPSS 22.0和HLM 6.08软件管理和分析数据,并进行了一系列包括描述性统计,相关分析和多层线性分析在内的统计分析,以探索创造力的发展轨迹以及学校支持与创造力发展之间的潜在关系。 研究结果如下:(1)4至6年级的小学高年级学生的创造力流畅性呈线性增长趋势,而创造力的灵活性和独创性呈非线性增长趋势。此外,创造力的初始水平与其增长速度呈正相关。(2)流畅性、灵活性和独创性的初始水平存在个体差异,流畅性和独创性的增长速度存在于个体差异。(3)小学高年级女生灵活性和独创性的初始水平显著高于男生。(4)在个体间水平上,教师支持与性别交互作用显著预测灵活性的初始水平;教师支持显著正向预测流畅性的初始水平及独创性的增长速度。(5)在个体内水平上,教师支持的变化显著正向预测流畅性的发展。 本研究是近几年国内创造力领域的第一篇追踪研究。本研究结果有助于深化关于小学生创造力发展规律的认识,对小学高年级学生创造力的培养有一定的指导意义。

Heritability of justice sensitivity

Subjects: Psychology >> Social Psychology

Justice is one of fundamental principles in human evolution, and justice sensitivity, both from the proself perspective (e.g., as victim) and the prosocial perspective (e.g., as observer, beneficiary, and perpetrator), matters in mental wellness and social interaction. However, it remains unclear to what extent individual difference in justice sensitivity is influenced by genetic versus environmental factors. Using a sample with 244 twin pairs, the present research was an attempt to determine what extent genetic factor plays a role in the inter-individual difference of justice sensitivity as well as whether different facets of justice sensitivity, namely, proself and prosocial perspective, share common genetic basis. Results showed that (1) all the four facets of justice sensitivity were moderately heritable (21%–33%) and that the non-shared environmental factors accounted for the rest variations (67%–79%); (2) associations between the prosocial facets of justice sensitivity were driven by common genetics (rg: .50–.65) and non-shared environmental (re: .24–.65) influences, whereas no strong evidence supported a genetic correlation between proself and prosocial justice sensitivity. The current findings provide novel evidence that sensitivity to injustice, especially to others’ suffering, is fundamentally grounded upon genetic origin, thus shedding light on the nature and nurture aspects of justice behavior.
