真实线和想象线的朝向辨别学习及其相互迁移

以往的朝向辨别学习普遍采用真实刺激作为材料,其特异性与迁移性是研究争论的焦点之一。该研究以实线和想象线为刺激,采用朝向辨别任务训练被试,系统考察两者朝向辨别学习的特点和相互关系。结果发现,训练实线和想象线任务的两组被试行为都有显著提高,并且这两种学习效果能部分地彼此迁移,且都能迁移到不同位置。该研究结果提示,不论是想象线的学习还是实线的学习都涉及高级脑区的参与,并且两者的学习有部分共同的脑机制。     

Child/Adolescent Abuse and Suicidal Behavior: Are They Sex Related?

The association between childhood and adolescent abuse and suicidal behavior, and the possible contribution of abuse to sex differences in non lethal suicidal behavior, was investigated. Data were extracted from the Israel‐based component of the WHO World Mental Health Survey (Kessler & Utsun, 2008a). Increased risk for ideation, plan, and suicidal attempt were associated with childhood abuse, and increased risk for attempt was associated also with abuse at adolescence. No associations with sex or sex by abuse interactions were observed. The higher frequency of childhood abuse among women could account in part for their higher rates of suicidal attempts as compared to men.     

Have Mental Health Education Programs Influenced the Mental Health Literacy of Those with Major Depression and Suicidal Ideation? A Comparison between 1998 and 2008 in South Australia

Mental health literacy is the knowledge and beliefs about mental disorders that aid their recognition, management, or prevention and is considered to be an important determinant of help‐seeking. This has relevance in suicide prevention, as depression, the clinical condition most frequently associated with suicidality, has been the target of community and professional education programs designed to enhance mental health literacy. In this study, whether such programs have influenced help‐seeking attitudes and behavior in those who are depressed and suicidal was considered. The results indicate that despite intensive community education programs over the last two decades, there has been little change in those who are depressed and suicidal in terms of their attitudes toward treatment seeking and, more importantly, their treatment‐seeking behavior. These results draw into question the value of current community education programs for those most vulnerable to suicidal behavior.     

Influence of the large–small split effect on strategy choice in complex subtraction

Two main theories have been used to explain the arithmetic split effect: decision‐making process theory and strategy choice theory. Using the inequality paradigm, previous studies have confirmed that individuals tend to adopt a plausibility‐checking strategy and a whole‐calculation strategy to solve large and small split problems in complex addition arithmetic, respectively. This supports strategy choice theory, but it is unknown whether this theory also explains performance in solving different split problems in complex subtraction arithmetic. This study used small, intermediate and large split sizes, with each split condition being further divided into problems requiring and not requiring borrowing. The reaction times (RTs) for large and intermediate splits were significantly shorter than those for small splits, while accuracy was significantly higher for large and middle splits than for small splits, reflecting no speed–accuracy trade‐off. Further, RTs and accuracy differed significantly between the borrow and no‐borrow conditions only for small splits. This study indicates that strategy choice theory is suitable to explain the split effect in complex subtraction arithmetic. That is, individuals tend to choose the plausibility‐checking strategy or the whole‐calculation strategy according to the split size.     

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。

Between mind and trace �� A research into the theories on Xin �� (Mind) of early Song Confucianism and Buddhism

From Han Yu’s yuan Dao 原道 (retracing the Dao) to Ouyang Xiu’s lun ben 论本 (discussing the root), the conflicts arising from Confucianists’ rejection of Buddhism were focused on one point, namely, the examination of zhongxin suo shou 中心所守 (something kept in mind). The attitude towards the distinction between mind and trace, and the proper approach to erase the gap between emptiness and being, as well as that between the expedient and the true, became the major concerns unavoidable for various thinkers to integrate the two teachings and to propel academic development. “To understand by mind” and “to blame for matter” were of crucial methodological significance for transcendence in both Confucianism and Buddhism. The arguments of Confucian scholars like Zhang Zai and the Cheng brothers on the identity of mind and trace and the unity of void and solid are mutually manifested. The same mind with the same principle means “mind is principle.” The “common axis of Confucianism and Buddhism” exists in the emphasis on mind beyond trace. The unification of mind and trace or the accordance of body and function has actually become the cardinal foundation for the possible mergence of the Three Teachings.
