为了解中小学生的生活满意度状况,课题组用中小学生的愉快心境来定义生活满意度,对我国10249名中小学生进行了调查。结果表明:85%的中小学生生活得很愉快或比较愉快,72.3%的中小学生有烦恼,经检验存在明显的年级、性别及城乡差异;中小学生最烦恼问题排在前三位的分别是学习紧张、父母期望值高、同学中没友谊;中小学生最烦恼问题与愉快心境相关的排序依次是:父母期望值高、学习紧张、家庭气氛紧张和同学中没友谊。  相似文献

如何公平合理地分配有限的资源是每一个组织都要面对的基本问题。在组织资源分配中存在一个有趣的现象, 即平均分配金钱往往会比平均分配特定商品让人感到更不公平。前人研究认为, 这是因金钱较之特定的商品具有更多交换价值导致的。3个实验对这一重要的心理现象进行了重新研究发现, 不仅交换价值影响资源分配的公平感, 而且资源的工资性质对其分配的公平感也有重要影响。这一发现丰富了Adams的公平理论, 同时也为组织更好地分配资源提供重要参考。  相似文献

目的:研究慢性不确定应激对大鼠急性整体热水浴后外周血和脾脏免疫细胞热休克蛋白70(Heat shock protein 70, HSP70)表达的影响。方法:随机将大鼠分成慢性应激组和控制组(每组14只)。通过4周的慢性不确定性应激诱发实验组大鼠明显的抑郁行为,此期间控制组大鼠正常饲养。随后给予大鼠42度整体热水浴刺激,维持直肠温度41度25min。热刺激后6h,采用流式细胞仪测定大鼠外周血和脾脏免疫细胞HSP70 水平。结果:与控制组大鼠相比,慢性应激大鼠在急性热刺激后HSP70合成明显减少。控制组大鼠的所有被检测的免疫细胞热应激后HSP70合成均明显增加。相反,慢性应激大鼠仅在外周血的单核细胞和粒细胞检测到HSP70合成增加,同时升高的水平明显低于控制组大鼠。结论:慢性应激降低大鼠免疫细胞HSP70的热诱导反应,提示HSP70保护性作用减弱可能参与了慢性应激损害免疫细胞功能的生物学过程  相似文献

他人期望类型对6~10岁儿童不同类型反语认知的影响   总被引:1,自引:0,他引:1       下载免费PDF全文
张积家  张萌 《心理学报》2005,37(6):767-775
以态度、话语含义和语言现象探测为指标,探讨他人期望类型对6~10岁儿童不同类型反语认知的影响。结果表明:⑴他人期望类型(内隐和外显)影响儿童对他人态度和话语含义的探测,但不影响语言现象探测;⑵儿童在反语认知不同方面表现出发展的不平衡性。6岁儿童已具备初步的反语认知能力,开始能够理解反语中说话者的态度和话语含义,但还不能正确解释反语现象。直至10岁,儿童对反语现象的解释能力仍在发展中。⑶儿童对不同类型反语认知水平不同。6岁儿童对两类反语的解释不存在显著差异,8岁和10岁儿童对两类反语解释均存在显著差异。与反语恭维比,8岁和10岁儿童能更好地解释反语批评。  相似文献

城市婴儿依恋类型分析及判别函数的建立   总被引:10,自引:0,他引:10       下载免费PDF全文

使用纵向和横向相结合的方法对64名12个月城市婴儿的母-婴对进行了研究,采用模拟的陌生情境法和Q-sort进行了依恋类型测验。结果发现:(1)对城市婴儿进行依恋类型判断的判别函数与国外进行的依恋判断函数非常相似;(2)婴儿不同的依恋类型具有跨年龄和跨情境的一致性;(3)中国城市婴儿的某些依恋类型具有与西方同类型婴儿不同的行为特点,其差异可能与文化和家庭抚养等因素有关  相似文献

动态视觉加工与儿童汉字阅读   总被引:14,自引:0,他引:14       下载免费PDF全文
使用视觉阈限测验、图片命名、字形相似性判断实验和语音意识等测验 ,考察了小学五年级儿童视觉加工技能与汉字阅读之间的关系。结果发现 :动态视觉加工与图片命名错误率、字形判断反应时和错误率、语音意识均有显著相关 ,静态视觉加工只与图片命名错误率相关显著 ;控制识字量后的偏相关分析显示 ,动态视觉加工与其他变量的相关关系不变 ,静态视觉加工与图片命名错误率的相关不再显著 ;回归分析发现动态视觉加工在识字量和语音意识的影响控制后 ,能够分别解释阅读流畅性、字形判断反应时和图片命名错误率 7%、2 5 %和 5 6 %的变化 ;语音意识能够解释识字量和阅读流畅性 9%和 10 %的变化 ;对差读者的动态视觉加工和语音意识分析发现 ,儿童在这两种测验上的个体差异很大。上述结果表明 ,阅读过程受基本知觉技能影响 ,动态视觉加工作用于汉字阅读的特定过程。  相似文献

Low-income, rural families face significant mental health risks. However, the understanding of resources associated with mental health risks is limited. The present study investigated the associations between perceived resources of low-income, rural mothers, and longitudinal maternal and child outcomes. This study utilized longitudinal data from the Family Life Project (N = 1203), from US rural areas with high poverty rates. Mothers reported their resources at 6-month postpartum, and their levels of depression, anxiety, and role overload were assessed at 2-year postpartum. Mothers reported their children's behavioral problems at 3 years old. Using a person-centered approach, we identified four maternal profiles: lower resources (7.1%); higher intra-family support (11.1%); higher inter-family support (20.8%); and higher resources (60.9%). In general, the higher resource profile was associated with lower mental health concerns of mothers and lower levels of behavior problems of children. Mothers in the higher intra-family support profile had disproportionately higher role overload. Children of mothers in the higher inter-family support profile showed disproportionately higher behavioral problems. Maternal partner status and education were significant predictors of resource profiles. Findings support the heterogeneity in perceived resources among low-income, rural families and different risk levels. Identifying these subgroups has significant implications for policy and interventions aimed toward this vulnerable population.  相似文献

While smartphones have brought many benefits and conveniences to users, there is continuing debate regarding their potential negative consequences on everyday cognition such as daily cognitive failures. A few cross-sectional studies have found positive associations between smartphone use and cognitive failures. However, several research gaps remain, such as the use of cross-sectional designs, confounds related to stable individual differences, the lack of validity in self-report measures of smartphone use, memory biases in retrospective self-reports, and the lack of differentiation between smartphone checking and smartphone screen time. To simultaneously address the aforementioned shortcomings, the current study examined the within-person associations between various objective indicators of smartphone use and daily cognitive failures using a 7-day daily diary study. Multilevel modelling revealed that smartphone checking, but not total smartphone screen time, predicted a greater occurrence of daily cognitive failures at the within-person level. Surprisingly, we also found negative within-person associations between smartphone screen time for social- and tools-related applications and daily cognitive failures, suggesting that some types of smartphone use may temporarily benefit one's cognitive functioning. This finding demonstrates the importance of studying the specific functions of smartphone use and their differential cognitive consequences, as well as highlights the complex relations between smartphone use and cognition.  相似文献

Microbial-based fertilizer has been widely used as a healthier and better alternative to agrochemical products. However, the effects of biofertilizers on the rhizospheric microbiota has rarely been investigated. Thus, the aim of this study was to investigate the effects of symbiotic fungus Trichoderma asperellum SL2-based inoculant on the soil bacterial population through next generation sequencing using a metabarcoding approach. The treatment plots were treated with T. asperellum SL2 spore suspension, while the control plots were treated with sterilized distilled water. The results showed similar bacterial microbiome profiles in the soil of control and T. asperellum SL2-treated plots. In conclusion, the application of the T. asperellum SL2 inoculant had not exerted a negative impact towards the bacterial population as similar observation was reflected in control plots. Nonetheless, future research should be conducted to investigate the effects of repeated application of T. asperellum SL2 over a longer period on the rice microbiota communities.  相似文献

Researchers have begun to explore the problem of mass data breaches, where consumer information is acquired by cybercriminals and sold in open markets on-line. Although studies document the social processes of the market and relationships between buyers and sellers, few have considered the revenues earned from market transactions. This study explored these issues using a sample of threads from 10 Russian language and 3 English language Web forums used to sell stolen data. Estimates were generated on the total number of transactions completed by participants along with the advertised prices for the two most common forms of personal information sold. The findings demonstrated that buyers may earn a range of revenues from the sale of stolen data, although this figure was smaller than the potential profits earned from fraudulent use and identity crimes by data buyers. The implications of this study for cybercrime research and policy are explored in detail.  相似文献
