Creativity in the Later Life: Factors Associated with the Creativity of the Chinese Elderly

This study examined a total of 140 elderly Chinese from China and the United States to investigate the relationship between attitude toward aging, daily activities, general health, education, and other demographics and rated creativity as measured by collage making and storytelling. The result of this study shows that creativity declines with age. However, education, general health status, daily activities, and the attitude toward aging are also found to be decisive factors of creativity. The implications of the findings are discussed.     

抑郁遗传基础的性别差异

人类抑郁有着复杂的遗传基础并存在性别差异。抑郁遗传基础的性别差异主要表现在遗传的直接效应及遗传与环境的交互效应两个方面。本文在回顾、梳理既有抑郁遗传基础性别差异相关研究的基础上,进一步探讨了性激素、个体环境敏感性和中间表型在性别差异形成中的作用。未来该领域应关注遗传对抑郁的动态影响,进一步探讨多基因交互作用、不同类型与性质的环境指标与抑郁遗传基础性别差异的关联。     

人类积极发展的资源模型——积极青少年发展研究的一个重要取向和领域

积极青少年发展观(Positive Youth Development Perspective,PYD)自20世纪90年代出现以来迅速推动了发展心理学知识的创新与应用,其中发展资源框架(The Developmental Assets Framework)是研究者进行深入探讨与应用研究的一个重要模型.发展资源是指一系列能够有效促进所有青少年获得健康发展结果的相关经验、关系、技能和价值观,本文在这一概念的基础上介绍了发展资源模型的结构、构建与发展基础以及基于该模型的重要假设及实证研究,并在综述研究的基础上探讨了资源模型的未来研究方向.     

Kinematics, kinetics, and electromyogram of ankle during drop landing: a comparison between dominant and non-dominant limb

The biomechanical difference between the dominant and non-dominant limb has seldom been studied during double-leg landing. The objective of this study was to evaluate the effectiveness of limb laterality on the ankle kinematics, kinetics and electromyogram (EMG) during drop landing. Sixteen healthy adults were recruited and dropped individually from platforms with three different heights (0.32 m, 0.52 m, and 0.72 m). The ground reaction force, ankle joint kinematics, and surface EMG of tibialis anterior (TA) and lateral gastrocnemius (LG) were measured in both lower extremities. Two-way analysis of variance was used to analyze the effects of laterality and dropping height. The peak angular velocities in dorsiflexion and abduction were significantly higher in the dominant ankle, whereas the pre- and post-landing EMG amplitudes of the TA were significantly higher in the non-dominant limb. Compared with the dominant side, the non-dominant ankle has a more effective protective mechanism in that excessive joint motion is restrained by greater ankle flexor activity. Compared with the non-dominant side, the dominant ankle joint is in greater injury risk during drop landing, and data measured in the dominant limb may produce more conservative conclusions for injury protection or prediction.     

MAOA基因rs6323多态性与同伴关系对男青少年早期抑郁的影响

以683名男青少年为被试(初次测评时M = 13.35岁; SD = 0.51), 综合运用传统回归分析和新兴显著性区域检验, 考察了MAOA基因rs6323多态性与同伴关系对青少年早期抑郁的交互作用及其表现形式。结果表明：当同伴接纳水平较低时, G等位基因携带者的抑郁水平表现出高于T等位基因携带者的趋势, 当同伴接纳水平较高时, G型基因携带者的抑郁水平显著低于T等位基因携带者; 同伴接纳可以显著预测G等位基因携带者的抑郁, 但对T等位基因携带者的抑郁无显著预测作用; rs6323多态性与同伴拒绝的交互作用亦不显著。研究结果提示, 同伴关系对MAOA基因与男青少年早期抑郁的关联起调节作用, 且其作用形式部分支持不同易感性模型观点。     

孝道的心理学研究现状

孝道是中国家庭文化的核心,但直到20世纪70年代,心理学家才开始对其进行实证研究。本研究简要论述了孝道的内涵及其社会心理学观,在综述前人有关研究的基础上,评述了目前孝道的心理研究在方法及内容上的不足,指出孝道是我国心理学中丞待加强的研究课题。     

青少年的自主期望、对父母权威的态度与亲子冲突和亲合

通过对704名城乡高一和高三年青少年的问卷调查,探讨了高中阶段青少年－父母关系、青少年的行为自主期望和对父母权威的态度的特点,以及青少年—父母关系与青少年的行为自主期望和对父母权威的态度之间的关系。结果显示,我国城乡青少年对父母权威的认同程度较高,而期望获得行为自主的年龄较晚;青少年的行为自主期望、对父母权威的态度与青少年—父母冲突与亲合在某些方面存在城乡、性别和年级差异;青少年对父母权威的认同程度越高,对与父母发生分歧的接受性越高,其与父母的关系越亲密;那些期望在较晚年龄获得行为自主的青少年,与父亲的冲突较多,但与母亲较亲密     

青少年早期父母惩罚的特点

采用问卷法考察青少年早期父母惩罚的特点。发现,父亲与母亲对青少年的惩罚具有相当的一致性;城市父母的惩罚多于农村父母,他们对青少年的限制与严厉多于农村父母;父母对男青少年的惩罚多于对女青少年,对男青少年的体罚与限制多于女青少年;城市父亲对初三青少年的惩罚多于初一和初二青少年,农村父亲和城市母亲的体罚随年龄而下降;父母惩罚以限制为主,其次是体罚,严厉最少。     

COMT基因Val158Met多态性与抑郁的关系

抑郁的发生具有重要的遗传学基础。COMT基因Val158Met多态性是抑郁的重要候选基因位点。目前有关COMT基因Val158Met多态性与抑郁关系的研究主要采用单基因设计、单基因-环境设计以及多基因-环境设计。有资料显示负性情绪偏向及其相关脑区可能在COMT基因Val158Met多态性与抑郁间起中介作用, 但具体机制仍有待探究。未来研究可以进一步考察被试的种族、年龄和性别等因素对COMT基因Val158Met多态性与抑郁关系的调节作用, 并通过采用多基因-环境设计, 综合运用积极与消极环境指标等措施深入考察负性情绪偏向和相关脑区在COMT基因Val158Met多态性与抑郁间的作用及其机制。
