Leisure Satisfaction Mediates the Relationships between Leisure Settings,Subjective Well-Being,and Depression among Middle-Aged Adults in Urban China

This study examined the role played by leisure satisfaction in the relationship between leisure settings (built and natural), subjective well-being, and depression among midlife residents of urban China. Structural equation modeling was used to analyze this conceptual model, exploring data taken from a representative sample of 663 Chinese urban middle-aged citizens included in the 2014 Chinese Leisure Study. Additionally, leisure satisfaction was tested as a mediator between leisure in nature and subjective well-being. The results indicate that leisure satisfaction mediates the relationship between specific leisure settings (i.e., leisure in nature and outdoor recreation), subjective well-being, and depression. The results therefore contribute to the literature by providing evidence of the relationship between leisure settings, subjective well-being, and depression through identification of the positive effects of leisure on nature. Future health interventions should therefore highlight the advantages of urban green spaces.

     

视知觉学习的认知与神经机制研究

知觉学习是指由于训练或经验而引起的长期稳定的知觉变化,是一种内隐性的学习。近20年来,视知觉学习的大量研究结果提示大脑皮层的各个区域,甚至包括初级感觉皮层,在成熟之后仍然具有一定的可塑性。该文根据近年来的研究进展,对视知觉学习在大脑的什么地方,什么时候,以何种方式发生等热点问题进行了探讨。研究提示,视知觉学习涉及了包括初级视皮层在内的多个大脑皮层,并且存在一种自上而下的调控机制;视知觉学习可以在不同的时间尺度上发生,快速学习之后将伴随着慢速学习;通过视知觉学习,人们对于复杂物体的表征将从高级皮层区域移向低级皮层区域,任务执行也将趋于自动化     

资本主义:被抗拒的与被利用的——从毛泽东早期的视角看

该文通过梳理毛泽东早年对资本主义的认识,试图阐明他在早期对资本主义所进行的现实和价值的双重批判,直接影响甚至决定了他后来对资本主义的种种态度,进而从这种考察中提出了两个既体现毛泽东独特的理论和实践品格同时又有助于我们理解并思考中国马克思主义的现状及其未来的重要问题。     

场依存—独立认知方式干扰抑制的比较

采用镶嵌图形测验筛选出28名被试完成Stroop干扰任务,探讨场依存—独立认知方式的个体在信息加工过程中对无关信息干扰抑制机制的特点和差异。结果表明：（1）场独立者在认知加工中具有较场依存者更强的对无关信息干扰的抑制效能。（2）在Stroop任务中,对字色也存在自动化加工,只是自动化程度较低。     

Tomasello关于语言获得的建构观

Michael Tomasello提出的用法建构语言获得理论认为儿童语言获得是一个以用法为基础、以功能为引导的逐步建构过程,而个体语言获得又以种系遗传的生物基础和文化历史积淀下来的语言环境为前提。本文在皮亚杰经典建构主义的框架下探讨Tomasello关于语言获得的建构观。     

小学生有意遗忘中认知抑制能力发展的研究

有意遗忘是一种新的关于记忆研究的实验范式．主要探讨个体抑制能力的发展。研究使用的实验材料分为单字和双字词．被试为小学二、四、六年级共90名学生。实验结果发现：①对于两种实验材料单字和双字词,小学生有意遗忘中的认知抑制能力随年级而提高;②小学生对两种材料的抑制能力存在差异,表明小学生在有意遗忘中的抑制能力受材料的意义性和材料难度的影响。     

人文关怀：ICU不容忽视的问题

ICU挽救了大量重症患者的生命,但也让很多患者留下了痛苦的回忆,ICU内人文关怀的缺失是发生这种现象的重要原因。疾病及医疗护理行为、ICU的环境、失眠、生命尊严与求生欲望之间的矛盾都使患者产生痛苦,由此提出要从制度层面完善学科设置,明确学科定位,加强专科人才培养,合理配置人力资源,完善管理政策,技术层面要对患者进行有效的镇静、镇痛治疗,重视患者诉求,减少有创操作,开展ICU床旁早期活动和康复治疗,从心理层面建立友好的ICU环境,注重医护患沟通,从多角度实施临终关怀,帮助患者减少痛苦。     

相似性词汇同时性加工与相继性加工的比较

为考查同时性学习与相继性学习在相似性材料学习中的特点,本研究以57名大学一年级学生为被试,用英语单词记忆测验考查了相似性英语新单词的同时性学习和相继性学习的差异。结果发现,对于相似性英语新单词来说,同时性学习的效果明显优于相继性学习效果。这表明,两种不同的学习方式在信息处理过程和信息加工水平上存在不同。     

High-capacity spatial contextual memory

Humans show implicit memory for complex spatial layouts, which aids in subsequent processing of these layouts. Research efforts in the past 5 years have focused primarily on a single session of training involving a dozen repeated displays. Yet every day, people encounter many more visual layouts than were presented in such experiments. In this study, we trained subjects to learn 60 repeated displays, randomly intermixed within 1,800 nonrepeated displays, spread over 5 consecutive days. On each day, the subjects conducted visual search on 360 new displays and a new set of 12 repeated displays, each repeated 30 times. Contextual memory was observed daily. One week after the fifth session, the subjects still searched faster on the repeated displays learned previously. We conclude that the visual system has a high capacity for learning and retaining repeated spatial context, an ability that may compensate for our severe limitations in visual attention and working memory.
