中学生知识获得过程是从情景记忆向语义记忆转化的过程

本研究探讨中学生的知识掌握过程。针对2001—2002年度上学期教学内容,对初中二年级学生的四门课程分别进行两次测验。对于每道选择题,学生首先选择正确答案,然后指出记忆的意识状态：记住的、知道的、猜测的。结果发现,学生记忆意识类型的转变(由记住向知道)取决于课程类型、保持时间和学生等级。对于不同课程,学生占优势的意识类型不同,自然学科知道的反应占优势,社会学科记住的反应占优势;优等生知道的反应多于其他学生;随着学习时间的延长,中学生的意识类型发生了由记住向知道的转变,这表明知识掌握过程中,中学生的知识表征发生了由情景记忆向语义记忆的转变。     

不同加工与记忆编码关系的ERP研究

通过事件相关电位(ERPs)记录,探讨了深、浅2种加工与记忆编码的相互关系。研究结果表明,（1）在深、浅两种加工条件下,首次使用汉字材料,获得了ERP相继记忆效应（Dm),随后再认正确的ERPs比随后再认不正确的ERPs有更大的晚正成分。（2）深加工的Dm效应始于N2波的前支（230－280ms)和N2波之后（395－800ms);而浅加工的Dm效应发生在345－490ms之间。深、浅加工的Dm效 涉及不同的脑区,这一结果支持深、浅两种加工的Dm效应可能是分离的结论。     

小学生喜好的外在奖赏及其运用

采用问卷调查法 ,以杭州市三所小学 3 1 8名小学生为被试 ,考察了他们对目前学校常用的 2 0种奖项的喜好特点。目的在于揭示这些奖项对小学生的潜在意义 ,为教师运用外在奖赏激励学生学习提供依据。结果表明 :(1 )小学生最喜欢社会认同类 ,其次是特权类 ,最后是学校奖项与零食类奖赏。他们最喜欢的前五种奖赏是 :书、奖状、好分数、玩电脑、去图书馆看书。 (2 )小学生在喜好的奖赏及其结构特点上均存在年级与性别差异。     

文本阅读中简单推理情境下的信息整合

研究采用动窗技术探讨了文本阅读中需要简单推理情境下的信息整合发生的时机。本研究通过三个实验证明了在需要简单推理情境下的文本阅读中 ,需要推理的信息整合是即时发生的 ,而不是经过追溯才发生 ,在这种情况下支持文本阅读的更新追随假设理论。同时本研究发现文本阅读中协调性整合不是以词为单位的。

非精神病凶杀者在博彩测验上的决策特征

探究非精神病凶杀者在博彩测验上的决策特征,对26名凶杀组被试和43名对照组被试实施博彩测验,发现(C+D)-(A+B)在5个试验区间差异无统计学意义,而(A+C)-(B+D)在5个试验区间存差异有统计学意义.两组被试在A卡片选择上差异有统计学意义,在B、C、D卡片选择上差异无统计学意义.凶杀组在博彩测验上采用了比对照组更多冒险的决策,但是总体上无意识地选择了损失较少的卡片.     

血管壁切应力的优与非优

在生理水平的血管壁切应力属于优性因子,能促进血管重建,抑制内皮细胞凋亡,调节内皮细胞分泌功能,使内皮细胞形态产生适应性变化;而显著升高或降低的血管壁切应力则属于非优因子,导致高血压恶性循环发生、促进动脉粥样硬化及动脉血栓形成。实现切应力非优向优转化的重要途径是降低高血压和选择性阻断切应力对基因表达的调节     

The Effect of General Creative Personality and Freedom of Task Choice on Adolescents' Social Creativity

This study investigated the effect of general creative personality and freedom of task choice on the social creativity of adolescents. The results indicated, first, that senior high school students scored higher than junior high school students. Second, girls scored higher than boys on originality, fluency, flexibility, appropriateness, and utility with regard to creative social problem‐solving. Third, freedom of task choice and its interaction with creative personality had significant effects on the originality, appropriateness, utility, flexibility, and fluency of social creativity. Adolescents who completed the task voluntarily scored higher on these dimensions than adolescents who completed it reluctantly and, among the voluntary adolescents, those with high and medium creative personality scored higher than those with low creative personality, whereas no such difference was found among the reluctant adolescents. Adolescents were more likely to show social creativity, and their general creative personality was more likely to be brought into effect under the freedom of task choice condition.

Open Workplace Climate and LGB Employees' Psychological Experiences: The Roles of Self‐Concealment and Self‐Acceptance

This study explores how an environmental factor (i.e., a perceived open climate) shapes lesbian, gay, and bisexual (LGB) employees' job satisfaction and job anxiety through the mediating role of self‐concealment. It also investigates the moderating role of self‐acceptance. Results from 315 LGB employees supported the conclusion that a perceived open climate for minority sexuality increased job satisfaction and decreased job anxiety. The open climate–job anxiety relationship was mediated by self‐concealment, and both stages of this mediation process were moderated by self‐acceptance. These findings offer useful insights for counselors and managers to help LGB individuals improve their workplace psychological experiences.
