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.     

Disorder-specific Effects of CBT for Anxious and Depressed Youth: A Meta-analysis of Candidate Mediators of Change

The commonalities between anxiety and depression have been discussed before, but few have delineated the potentially different mechanisms through which treatments work for these populations. The current study conducted a comprehensive review of child and adolescent randomized clinical trials that tested cognitive-behavioral therapy (CBT) for anxiety or depression. All studies were required to have assessed both treatment outcomes and at least one theory-specific process target, including behavioral, physiological, cognitive, and coping variables. Using a meta-analytic approach, CBT demonstrated positive treatment gains across anxiety, depression, and general functioning outcomes. CBT for anxiety also produced moderate to large effects across behavioral, physiological, cognitive, and coping processes, with behavioral targets demonstrating potentially the greatest change. CBT for depression produced small effects for cognitive processes but nonsignificant effects for behavioral and coping variables. Findings were generally consistent with CB theory but suggest potentially different mediators in the treatment of anxiety and depression. Results are discussed in terms of implications for mechanisms research, theories of change, and treatment development.     

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

Causal attribution for interfirm contract violation: a comparative study of Chinese and American commercial arbitrators

In this study, the authors examined differences between Chinese and American commercial arbitrators. They predicted and found that Chinese arbitrators make higher awards for interfirm contract violations than Americans. This difference is partially explained by differences in attributions. Prior theory suggests, and the authors found, that the Chinese tend to have more internal attributions for events when observing group actions. When evidence provided to arbitrators is mixed (evidence is provided for both internal and external attributions), Chinese-American differences in awards become even stronger.     

青少年自尊与攻击的关系：中介变量和调节变量的作用

以705名初、高中生为被试,采用量表法和同伴提名法收集数据,探讨了自尊与攻击的关系以及对二者关系可能有影响的中介变量和调节变量的作用。结果表明：（1）自尊与攻击的相关系数为-0.21,这说明低自尊与高攻击有关;（2）回归方程纳入自控后,自尊对攻击的预测在统计意义上不明显,表明自尊通过自控对攻击产生影响,自控在自尊与攻击的关系中起着中介的作用;（3）社会地位对自尊与攻击之间的关系具有调节作用,它调节着两者关系的强度;（4）社会影响对自控的中介作用具有调节作用     

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     

Self-Explanations: How Students Study and Use Examples in Learning to Solve Problems

The present paper analyzes the self-generated explanations (from talk-aloud protocols) that “Good” and “Poor” students produce while studying worked-out examples of mechanics problems, and their subsequent reliance on examples during problem solving. We find that “Good” students learn with understanding: They generate many explanations which refine and expand the conditions for the action parts of the example solutions, and relate these actions to principles in the text. These self-explanations are guided by accurate monitoring of their own understanding and misunderstanding. Such learning results in example-independent knowledge and in a better understanding of the principles presented in the text. “Poor” students do not generate sufficient self-explanations, monitor their learning inaccurately, and subsequently rely heavily on examples. We then discuss the role of self-explanations in facilitating problem solving, as well as the adequacy of current AI models of explanation-based learning to account for these psychological findings.
