笔画复杂性和重复性对笔画和汉字认知的影响

采用笔画识别和词汇决定的方法 ,对汉字笔画认知和笔画在汉字认知中的作用作了考察。实验一探讨了汉字笔画自身的复杂性对笔画认知的影响。结果表明 ,笔画自身的复杂性对笔画认知无显著影响 ,识别简单笔画和识别复杂笔画的反应时与错误率无显著差异。实验二考察了笔画的重复性对汉字认知的影响。结果表明 ,汉字认知中存在笔画重复性效应。笔画重复较多的汉字比笔画较少重复的汉字识别时间短 ,错误率亦低。整个实验结果支持笔画是汉字加工的基本单元的假设     

城市婴儿依恋类型分析及判别函数的建立

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     

构建社会主义和谐社会中的道德建设新指向

构建社会主义和谐社会的命题,要求实现道德建设"由圣入凡"的转变.这种转变的新指向是:以日常生活批判实现从传统道德向现代道德的转化,把以人为本与现代性"平民化人格"联系起来,以生态和谐观念寻求公德与私德的统一.     

儿童早期词汇获得的词类差

儿童早期词汇获得存在词类差异,很多语言中名词比例都要高于其他词类,因此一些研究者提出“名词优势”理论。但是,一些对汉语和韩语的研究发现,儿童早期获得的动词比例与名词没有显著差异,甚至高于名词,同时汉语和韩语动词比例也远大于英语动词比例。针对不同语言儿童早期获得的动、名词比例差异现象,研究者认为语言结构特征和成人对孩子的言语输入可以解释不同语言儿童早期词汇中动、名词比例的差异,其中成人言语中词类的频率、单词位置、词形变化复杂性和语用等因素都会影响儿童早期词汇获得。此外,不同的词汇测量方法、观察情境、词类定义、词汇量水平、单词理解与说出也会造成不同研究结果之间的差异

慢性应激对大鼠行为和免疫细胞热休克蛋白70表达的影响

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     

Exploring correlations between positive psychological resources and symptoms of psychological distress among hematological cancer patients: a cross-sectional study

Hematological cancer patients experience high levels of psychological distress during diagnoses and intensive treatments. The aim of the present study is to explore the effects of positive psychological resources on depressive and anxiety symptoms in hematological cancer patients. This survey was conducted in a hospital during the period from July 2013 to April 2014. A total of 300 inpatients were recruited and finally 227 of them completed the questionnaires. Questionnaires included demographic and clinical variables, the Center for Epidemiologic Studies Depression Scale, the Self-Rating Anxiety Scale, the Life Orientation Scale-Revised, the General Perceived Self-Efficacy Scale, and the Resilience Scale-14. Results showed that the prevalence of depressive and anxiety symptoms was 66.1 and 45.8%, respectively. Both optimism (β = ?.479, p < .001) and resilience (β = ?.174, p < .05) were negatively associated with depressive symptoms, and optimism (β = ?.393, p < .001) was negatively associated with anxiety symptoms. However, resilience (β = ?.133, p > .05) was not significantly associated with anxiety symptoms, and self-efficacy was not significantly associated with depressive (β = ?.032, p > .05) or anxiety symptoms (β = ?.055, p > .05). The results suggest that hematological cancer patients who possess high levels of positive psychological resources may have fewer symptoms of psychological distress. The findings indicate that enhancing positive psychological resources can be considered in developing intervention strategies for decreasing depressive and anxiety symptoms.     

特征整合与加工深度对道德概念容器隐喻联结的影响

提出了隐喻提取假说将隐喻联结的形成和提取进行分离, 并通过3个实验探究了道德概念与容器空间的隐喻联结及其受知觉加工深度和特征整合程度的影响。实验1采用空间Stroop范式, 实验2a和实验2b均采用启动范式, 实验3a和实验3b均采用加入任务要求的Stroop范式。结果发现：(1)在经典Stroop范式中未发现道德概念与容器空间的隐喻联结; (2)在启动范式中发现, 较深知觉加工深度下道德概念与容器空间存在较弱的隐喻联结; (3)在较高特征整合程度的Stroop任务中, 道德概念与容器空间存在较强的隐喻联结。结果表明：道德概念与容器空间存在道德为内、不道德为外的隐喻联结, 这种隐喻联结在映射上表现为双向性, 并且受到特征整合程度和知觉加工深度的影响, 同时也为隐喻提取假说提供了证据支持。

Using game theory to examine incentives in influenza vaccination behavior

The social good often depends on the altruistic behavior of specific individuals. For example, epidemiological studies of influenza indicate that elderly individuals, who face the highest mortality risk, are best protected by vaccination of young individuals, who contribute most to disease transmission. To examine the conditions under which young people would get vaccinated to protect elderly people, we conducted a game-theory experiment that mirrored real-world influenza transmission, with "young" players contributing more than "elderly" players to herd immunity. Participants could spend points to get vaccinated and reduce the risk of influenza. When players were paid according to individual point totals, more elderly than young players got vaccinated, a finding consistent with the Nash equilibrium predicting self-interested behavior. When players were paid according to group point totals, however, more young than elderly players got vaccinated-a finding consistent with the utilitarian equilibrium predicting group-optimal behavior-which resulted in higher point totals than when players were paid for their individual totals. Thus, payout structure affected whether individuals got vaccinated for self-interest or group benefit.
