内隐记忆特点的新探索

从1911年Claparede发现遗忘症病人有回避条件反射记忆到Graf和Schacter于1985正式提出内隐记忆这一概念,再到内隐记忆成为认知心理学的研究焦点,研究者对内隐记忆的定义、研究方法等都进行了逐渐深入的探讨。在此基础上,内隐记忆的相关特点也日益明晰,概念性内隐记忆、知觉性内隐记忆、自动加工记忆等各亚类均具有提取自动化、年龄独立性等共同特征,但在编码、脑机制诸方面存在差异。

Parent Prediction of Autism Spectrum Disorder in Infants at Risk: A Follow-up Study

Later-born siblings of children with autism spectrum disorder are considered at biological risk for autism spectrum disorder and the broader phenotype. Early screening may detect first signs of autism spectrum disorder and expedite diagnosis and early intervention. In this follow-up study, we re-examine a validated second-degree autism spectrum disorder screener for children at biological risk of autism spectrum disorder, the parent observation of early markers scale. Using available follow-up information up to age 13 years, 110 children (the original 108 infants plus 2 infants recruited after the completion of the original study) were divided into three groups: diagnosed group (n?=?13), lost diagnosis group (n?=?5), and undiagnosed group (n?=?92). The parent observation of early markers scale continued to show acceptable predictive validity. The parent observation of early markers scale total scores and mean number of elevated items were significantly higher in the diagnosed group than the undiagnosed group. The lost-diagnosis group did not differ from the undiagnosed group on parent observation of early markers scale total scores and elevated items at any age, but the lost-diagnosis group had significantly lower total scores, and number of elevated items than the diagnosed group starting at 18 months. Both autism spectrum disorder core and subsidiary behaviors differentiated the diagnosed and undiagnosed groups from 9 to 36 months of age. We hereby provide further evidence that the parent observation of early markers scale may serve as a low-cost early screener for autism spectrum disorder in at-risk children and pinpoint specific developmental ,and behavioral problems that may be amenable to very early intervention.     

Parenting Self-Efficacy and Parental Involvement: Mediators or Moderators Between Socioeconomic Status and Children’s Academic Competence in Japan and Korea?

We examined the causes of a growing achievement gap associated with socioeconomic status (SES) in Korea and Japan, testing whether parenting self-efficacy (PSE) and parental involvement (PI) mediated or moderated the association of SES to children’s school-related competence (SRC). Three hundred and seventy-two Korean and 309 Japanese mothers of first- and second-grade children completed a parenting survey. Japanese mothers’ education and PSE were directly associated with SRC. PSE moderated the association of education to SRC, with higher PSE of college-educated mothers positively associated with SRC. In the Korean sample, household income was associated with SRC directly as well as indirectly through PSE.     

The effects of direction similarity in visual working memory: Behavioural and event-related potential studies

Object similarity can improve visual working memory (VWM) performance in the change-detection task, but impair the recognition performance when it occurs at retrieval of VWM in the recognition task. The effect of direction similarity is an issue that has not been well resolved. Furthermore, electrophysiological evidence in support of the mechanisms that underlie the effects of similarity is still scarce. In the current study, we conducted three behavioural experiments to examine the effects of direction similarity on memory performance with regard to both the encoding and retrieval phases of VWM and one event-related potential (ERP) experiment to explore the neural signatures of direction similarity in VWM. Our behavioural studies indicated that direction similarity improved performance when it occurred at the encoding phase but impaired performance when it occurred at the retrieval phase. Moreover, the ERP experiment showed that the amplitude of the contralateral delay activity (CDA) increased with the increasing set size for similar but not dissimilar directions. In addition, the CDA amplitude for similar directions was lower than that for dissimilar directions at set size 2. Taken together, these findings suggest that direction similarity at encoding has a positive effect on VWM performance and at retrieval has a negative effect. Given that VWM capacity depends on information load and the number of objects, the positive effect of similarity may be attributed to reduced information load of memory objects.     

学前儿童执行功能与问题行为的关系:情境和性别的特异性

运用追踪设计检验了学前儿童执行功能特定成分和问题行为跨情境和性别的关系。选取101名学前儿童（48名男孩）为研究对象,采用实验任务测量儿童的执行功能,一年后采用母亲和教师报告分别收集儿童在家庭和学校情境的问题行为。结果发现,控制儿童年龄后：（1）在男孩中,抑制控制、认知灵活性和工作记忆负向预测一年后家庭情境的外化问题,认知灵活性负向预测一年后学校情境的外化问题,抑制控制正向预测一年后学校情境的内化问题;（2）在女孩中,执行功能三个成分均不能显著预测家庭情境的问题行为,认知灵活性正向预测一年后学校情境的外化问题。执行功能三个成分与问题行为间存在不同效应模式,且存在跨情境和性别的特异性。     

冯契对马克思主义哲学的创新性探索

作为当代著名的马克思主义哲学家,冯契对马克思主义哲学做了三方面的创新性探索。首先,丰富和拓展了马克思主义认识论体系：将狭义认识论拓展为广义认识论,充实了认识论中“知觉”和“意见”两个范畴,将“疑问”和“观点”两个普通概念提升为认识论的范畴。其次,建构了独特的马克思主义辩证逻辑体系：探讨了怎样将哲学理论化为思维方法,建构了以“类”“故”“理”为骨架的逻辑范畴体系,概括了辩证逻辑方法论的五个环节。再次,梳理与概括了中国古代自然科学成就：运用与发展了比类取象、比类运数的科学方法,设计、运用了实验手段。     

Culture and the distinctiveness motive: constructing identity in individualistic and collectivistic contexts

The motive to attain a distinctive identity is sometimes thought to be stronger in, or even specific to, those socialized into individualistic cultures. Using data from 4,751 participants in 21 cultural groups (18 nations and 3 regions), we tested this prediction against our alternative view that culture would moderate the ways in which people achieve feelings of distinctiveness, rather than influence the strength of their motivation to do so. We measured the distinctiveness motive using an indirect technique to avoid cultural response biases. Analyses showed that the distinctiveness motive was not weaker-and, if anything, was stronger-in more collectivistic nations. However, individualism-collectivism was found to moderate the ways in which feelings of distinctiveness were constructed: Distinctiveness was associated more closely with difference and separateness in more individualistic cultures and was associated more closely with social position in more collectivistic cultures. Multilevel analysis confirmed that it is the prevailing beliefs and values in an individual's context, rather than the individual's own beliefs and values, that account for these differences.     

充分条件句语义关系知觉对条件推理的影响

作者通过实验考察了大学生被试对五种充分条件句语义关系知觉对其条件推理的影响。两个实验的结果表明,被试对条件句中前后件之间语义关系的知觉理解影响和调节其相应的条件推理的成绩。实验1新发现,被试对充分条件句后件对前件必要性的知觉理解存在难易差异,对许可句和定义句的后件必要性容易知觉,对偶然句、义务句和因果句的后件必要性难以知觉。实验2新发现,被试对充分条件句后件对前件必要性的知觉理解的难易差异导致被试在否定后件式推理成绩上的差异,对许可句和定义句的否定后件式推理成绩显著高于对偶然句、义务句和因果句的否定后件式推理成绩,对充分条件句否定后件式推理成绩随对后件必要性知觉增加而增加。
