从热力学角度审视和研究亚健康

从中医学及其与热力学的关联分析角度来认识亚健康的现象和实质."整体观念,以平为期"是中医学与热力学共同的理论基础.亚健康是人体处于"无序"的熵增状态,亚健康的干预就是人体从外界吸收"负熵流",降低系统紊乱度,从而达到新的有序状态,恢复健康.亚健康状态可以用热力学基本状态函数刻画,运用中医学的思维模式和热力学的研究方法,可构建基于热力学的亚健康诊断方法,进而为亚健康研究提供一个新的视角.     

注意分心对定义一体化编码的影响

通过考察编码阶段注意分心对定义一体化条件下联结记忆成绩的影响,探究定义一体化编码对注意资源的依赖程度。使用注意分心范式,在记忆编码过程操作无分心、奇偶分心和大小分心条件,比较不同注意条件下的联结记忆成绩。结果发现:与无分心条件相比,定义一体化下的联结记忆成绩在两种分心条件下没有显著变化,而造句下的联结记忆成绩在两种分心条件下显著降低。当前发现表明了定义一体化编码较少依赖于注意资源,这深化了对定义一体化编码机制的认识。     

拓广分部评分模型下计算机自适应测验变加权选题策略

摘要: 在计算机自适应测验中, 对0-1评分模型按a-分层选题是高效安全的策略,但多级评分模型的项目难度/步骤参数有多个而无法直接应用这种选题策略。信息函数能够很好地综合项目所有参数及能力参数,但最大信息量选题策略会影响考试安全。本文提出一种变加权选题策略,它通过调用一个与信息量相关联的函数,该函数与信息量成正比,与区分度的某个幂函数成反比,从而达到既能综合项目所有参数又按a分层的效果。在GPCM模型下用蒙特卡罗实验进行比较研究,结果显示新的选题策略总体效果比已有相关结果好。     

特征相似性、类别标签与因果关系在归纳推理中的作用

采用人工材料,比较类别标签、特征相似性与因果关系对归纳推理强度的影响。包括两个实验,实验1比较类别标签与特征相似性对归纳推理的影响,结果表明,当类别标签对归纳推理的影响显著强于特征相似性时,不能将类别标签等同于一个相似性特征。实验2进一步探讨类别标签与因果关系对归纳推理的作用,结果表明,因果关系作用明显强于类别标签的作用。综合两个实验的结果并整合前人相关研究,提出了不同关系影响归纳推理的强度假想。     

情绪智力对大学生创业意向的影响:成就动机和创业自我效能感的链式中介作用

为探讨情绪智力、成就动机、创业自我效能感和大学生创业意向之间的关系。使用情绪智力量表、成就动机量表、创业自我效能感量表和创业意向量表对986名大学生进行调查。结果表明:(1)成就动机中介了情绪智力与大学生创业意向之间的关系。(2)创业自我效能感中介了成就动机与大学生创业意向间的关系。(3)创业自我效能感中介了情绪智力与大学生创业意向之间的关系。(4)成就动机和创业自我效能感在情绪智力与大学生创业意向之间起链式中介作用。     

群际接触对外群体信任的影响:内群体认同的中介效应

Age differences in forgiveness: the role of future time perspective

This study investigated whether the age trend in forgiveness is partly attributable to age differences in time perspective. Eighty-nine younger and 91 older adults were randomized into 3 experimental conditions: time-expanded, time-limited, and neutral. They responded to hypothetical offensive scenarios and rated the degree to which they would forgive the perpetrator. Results showed that older adults were more forgiving than younger adults, but regardless of age, those in the time-limited condition were more forgiving than those in the time-expanded or the neutral condition. An Age x Time perspective interaction showed that only in older adults did a time-expanded manipulation lead to lower forgiveness than the neutral condition.

Assessment of Major Life Events for Hong Kong Adolescents: The Chinese Adolescent Life Event Scale

Previous Chinese research on adolescent life stress adopted life event scales that were directly translated from Western measures. To address the methodological and cultural issues overlooked by the import approach, the present research aimed at constructing a life event scale for Hong Kong adolescents. Study 1 was conducted to congregate items for the Chinese Adolescent Life Event Scale (CALES). The CALES contains 44 items derived from 618 Hong Kong adolescents. Study 2 revealed adequate test–retest reliability and criterion-related validity for the CALES. Moreover, the CALES yielded stronger relationships with depression than did the translated life event measures. Results suggest that the CALES is appropriate for assessing life events for Hong Kong adolescents. Both unique features of the CALES and life events found only in the translated measures are examined. Implications for Chinese research on life stress are discussed.     

Perceived Parental Rearing Style, Self-Esteem and Self-Criticism as Predictors of Happiness

This study set out to determine to what extent three recalled parental (care, discouragement of behavioural freedom, denial of psychological autonomy), self-esteem, and self-criticism predicted self-rated happiness in a normal, non-clinical, population of young people in their late teens and early 20s. Three hundred and sixty-five participants completed four questionnaires: Parental Bonding Instrument (Parker, Tupling and Brown: 1979, British Journal of Medical Psychology 55, pp. 1–10), Rosenberg Self-Esteem Scale (Rosenberg: 1965, Society and the Adolescent Self-Image (Princeton University Press, Princeton, NJ)), Self-Criticism Questionnaire (Brewin, Firth-Cozens, Furnham and McManus: 1992, Journal of Abnormal Psychology 101, pp. 561–566), and the Oxford Happiness Inventory (Argyle, Martin and Crossland: 1989, Recent Advances in Social Psychology: An International Perspective (Elsevier, North Holland)). Regressions showed self-esteem (the positive five items) to be the most dominant and powerful correlate of happiness. Maternal care was a significant correlate of both self-esteem and self-criticism. Maternal care was the only direct correlate of happiness when paternal and maternal rearing styles were examined together suggesting that the warmth showed by mothers towards their children was particularly beneficial in increasing the offsprings' scores on self-reported happiness.

双任务干扰的注意资源限制机制:来自汉字笔画数效应的证据

该研究的两个实验采用心理不应期范式,探讨了重叠任务情境下双任务的相互干扰机制。实验中被试相继完成高低音的辨别任务(T1)和汉字外在特征(颜色或笔画数)的任务判断(T2),T1和T2间采用变化的SOA。结果发现:(1)T1的反应选择导致T2的加工成绩大幅下降,PRP效应非常显著。(2)当T1占据中枢瓶颈时,T2和T1在中枢瓶颈中并行得到加工并导致T1的加工效率显著下降。(3)由于注意资源的有限性,具有自动激活特征的汉字同样受瓶颈机制的限制。只要存在对注意资源的二次分配就会存在瓶颈的调节机制。
