学龄期儿童性心理研究现状及展望

学龄期是个体性心理发展的转折期、关键期。本文在回顾学龄期儿童性心理研究发展脉络的基础上,从国内外学龄期儿童的性心理概念与结构、性心理的发展、研究方法以及性心理健康等几方面概述了该领域现状。该领域研究的进一步发展有赖于学龄期儿童性心理测量工具的改进,影响学龄期儿童性心理健康因素的澄清以及性心理健康教育策略的有效整合。开发出中国情景下的学龄期儿童性心理调查问卷,以期能科学评估他们性心理结构特点和发展应在未来研究中得到重视。     

Meaning in Life Promotes Proactive Coping via Positive Affect: A Daily Diary Study

Previous research on meaning in life and coping has generally been focused on reactive coping strategies and global meaning judgments. To extend this, the present study used a daily diary method to collect longitudinal data, and examined whether individuals’ daily meaning in life predicted use of proactive coping techniques and whether this relationship was mediated by positive affect. Adults (n = 132) completed a diary to track their meaning in life and positive affect every day for 21 consecutive days. Global levels of meaning in life, positive affect, and proactive coping were measured both at baseline and after the daily reporting phase ended. Hierarchical linear modeling demonstrated that daily meaning in life was a positive predictor of daily positive affect. Furthermore, combined latent growth curve and structural equation models indicated that the rate of change in daily meaning in life predicted change in proactive coping over the course of the study, and that this relationship was mediated by change in positive affect. The mediational effect of positive affect in the relationship between meaning in life and proactive coping was also verified by the reported global levels of these variables. These findings suggest that meaning in life may play an important role in coping with future life stress. Our discussion centers on the positive functions of meaning in life and the mechanisms of the predictive relationship of meaning in life in terms of proactive coping.     

Metaphorical mapping between raw–cooked food and strangeness–familiarity in Chinese culture

Previous research has demonstrated metaphorical mappings between physical coldness–warmth and social distance–closeness. Since the concepts of interpersonal warmth are frequently expressed in terms of food-related words in Chinese, the present study sought to explore whether the concept of raw–cooked food could be unconsciously and automatically mapped onto strangeness–familiarity. After rating the nutritive value of raw or cooked foods, participants were presented with morphing movies in which their acquaintances gradually transformed into strangers or strangers gradually morphed into acquaintances, and were asked to stop the movies when the combined images became predominantly target faces. The results demonstrated that unconscious and automatic metaphorical mappings between raw–cooked food and strangeness–familiarity exist. This study provides a foundation for testing whether Chinese people can think about interpersonal familiarity using mental representations of raw–cooked food and supports cognitive metaphor theory from a crosslinguistic perspective.     

二维场景旋转下的背景提示效应

在视觉搜索中,特定背景与目标位置的多次联合呈现能够促进搜索绩效,这被称为背景提示效应。本研究探讨背景提示效应能否迁移到二维旋转后的视觉场景中去。选择大学生为被试,采用2(场景类型:重复、新异)×7(时间阶段:1~7)×3(旋转角度:0°、45°、60°)的三因素混合实验设计。被试在进行背景提示效应的学习后,随机分为三组分别在旋转了0°、45°、60°的场景中继续执行视觉搜索任务。结果发现:三组被试都习得了背景提示效应,且都迁移到了旋转后的场景中。这表明背景提示效应可能存在更高级的编码方式。     

高校教师工作家庭关系、工作特征与生活满意度的研究

该研究通过对1149位高校教师的问卷调查,探讨了高校教师工作家庭关系的特点及其与工作特征、生活满意度的关系.结果发现:1)高校教师体验到的工作家庭冲突与工作家庭促进存在较弱的负相关.2)男性教师体验到的家庭-工作冲突显著高于女性教师,在工作-家庭冲突和工作家庭促进方面差异不显著.3)工作要求能正向预测工作家庭冲突和工作家庭促进;个人对工作家庭平衡的控制感能降低工作-家庭冲突、提升工作家庭促进,但同时也会使家庭-工作冲突增加.4)工作家庭促进会显著地提升教师对工作和家庭的满意感.工作-家庭冲突会削弱工作满意度,家庭-工作冲突则会导致家庭满意度下降.     

心理授权、心理氛围与工作绩效的关系

为获低成本、高绩效和高弹性的竞争优势,组织授权员工的重要性日益增加.本文对深圳、上海和长沙的18家企业307名员工的心理氛围、心理授权与工作绩效的关系进行了研究,结果表明:①心理氛围、心理授权与工作绩效两两之间都存在显著正相关关系;②心理授权、心理氛围能有效地预测任务绩效、周边绩效和工作绩效;③心理氛围能有效地预测工作绩效,其中心理授权是心理氛围与工作绩效之间关系的缓冲变量,缓冲作用主要是通过自我效能和自主性两个维度来实现的.

Purple sweet potato color repairs d-galactose-induced spatial learning and memory impairment by regulating the expression of synaptic proteins

Purple sweet potato color (PSPC), a class of naturally occurring anthocyanins used to color food (E163), has been reported to possess a variety of biological activities, including anti-oxidant, anti-tumor, and anti-inflammatory. The effect of PSPC on the spatial learning and memory of mice treated with d-galactose (d-gal) was evaluated by the Morris water maze; d-gal-treated mice had decreased performance compared with mice in the vehicle and PSPC groups, while the PSPC + d-gal group showed significantly shortened escape latency to platform, increased swimming speed, more target quadrant search time and more platform crossings as compared with the d-gal group. Brain functions, such as memory formation and recovery of function after injury, depend on proper regulation of the expression levels of the pre- and post-synaptic proteins. We investigated the expression of four pre-synaptic proteins (growth-associated protein-43, synapsin-I, synaptophysin, and synaptotagmin) and two post-synaptic proteins (post-synaptic density protein-95 and Ca²⁺/calmodulin-dependent protein kinase II) in the hippocampus and cerebral cortex, respectively, in response to different treatments. Western blotting analysis showed that there were significant decreases in the expression of these representative synaptic proteins in the hippocampus and cerebral cortex of d-gal-treated mice. Interestingly, these decreased expression levels of synaptic proteins could be reversed by PSPC. The levels of expression of these representative synaptic proteins in mice treated with PSPC alone were not significantly different from those in untreated mice. The results of this study suggested that memory impairment and synaptic protein loss in d-gal-treated mice may be improved by treatment with PSPC.     

Synaptic localization of GluR4-containing AMPARs and Arc during acquisition, extinction, and reacquisition of in vitro classical conditioning

Data suggest that modulation of synaptic strength by incorporation of GluR4-containing AMPARs occurs during conditioned response (CR) acquisition in an in vitro model of classical conditioning. Here we extend these findings by showing that synaptically localized GluR4 subunits parallels the expression of CRs during conditioning training in which there is differential expression of CRs, such as during acquisition, extinction, and reacquisition. Moreover, colocalization and coimmunoprecipitation data suggest that Arc associates with GluR4-containing AMPARs during these different training procedures. Once induced, Arc remains present in synapses during these phases of conditioning. The results are consistent with the interpretation that synaptic incorporation of GluR4-containing AMPARs supports the expression of CRs in this preparation, and that Arc may be involved in trafficking of GluR4 subunits during conditioning. Moreover, the maintained presence of synaptically localized Arc during all phases of conditioning examined indicates that synapses do not return to their na?ve state after extinction and that, given the potential trafficking function of Arc, may facilitate relearning after extinction.     

灵异照片与鬼神摄影

2006年1月6日《大河报》题为《真奇怪——身份证人像采集系统在舞钢一农民身上“失灵”》的报道引发了众多媒体和世人关注。一个正常人的影像怎么可能在照片中显示不出来?难道真的见鬼了?究竟是特异功能还是灵异照片,或者根本就是一场假把戏?为此,《北京科技报》记者亲自赶往“照相”事发地河南进行调查。然而,调查过程中,“隐身人”被无一例外地拍入到记者的相机里。同时,当记者重新与最早报道此事的《大河报》记者接触后,确定灵异照片现象纯属骗局,“河南隐身人”根本不存在。的确,事实胜于雄辩,所有稀奇古怪,看似非常惊人的事情,如果经过…
