排名列表项目展示方式对于项目评价的极化效应

排名列表是帮助消费者快速识别品牌或产品优劣的手段。研究基于空间隐喻理论, 探究排名列表的不同展示方式(垂直vs水平)对消费者列表项目评价的极化影响及作用机制。通过5个实验发现: 消费者对于垂直排名列表相比水平排名列表中的项目具有更大的评价极化效应, 并且验证了项目感知差异在上述关系中的中介作用, 即垂直排名列表的评价极化效应是由个体较高的排名列表项目感知差异所驱动的。此外, 当属性可评估性较低时, 才会出现不同列表项目的评价极化效应; 相反, 当排名列表项目属性可评估性较高时, 该评价极化效应消失。     

工作记忆、认知灵活性对幼儿阅读理解的影响:推理能力、心理理论的中介作用

研究选取202名4～5岁的幼儿为研究对象,其中男孩102人、女孩100人,研究采用测验法考察幼儿年龄、工作记忆、认知灵活性、推理能力、心理理论与其阅读理解之间的关系。研究采用Amos22.0验证模型。结果发现,4～5岁幼儿的年龄、心理理论、推理能力能直接影响其阅读理解。认知灵活性、工作记忆会通过影响心理理论、推理能力间接影响阅读理解,并且心理理论、推理能力在其中起完全中介作用。     

Item strength affects working memory capacity

Do the processing and online manipulation of stimuli that are less familiar require more working memory (WM) resources? Is it more difficult to solve demanding problems when the symbols involved are less rather than more familiar? We explored these questions with a dual-task paradigm in which subjects had to solve algebra problems of different complexities while simultaneously holding novel symbol–digit associations in WM. The symbols were previously unknown Chinese characters, whose familiarity was manipulated by differential training frequency with a visual search task for nine hour-long sessions over 3 weeks. Subsequently, subjects solved equations that required one or two transformations. Before each trial, two different integers were assigned to two different Chinese characters of the same training frequency. Half of the time, those characters were present as variables in the equation and had to be substituted for the corresponding digits. After attempting to solve the equation, subjects had to recognize which two characters were shown immediately before that trial and to recall the integer associated with each. Solution accuracy and response times were better when the problems required one transformation only; variable substitution was not required; or the Chinese characters were high frequency. The effects of stimulus familiarity increased as the WM demands of the equation increased. Character–digit associations were also recalled less well with low-frequency characters. These results provide strong support that WM capacity depends not only on the number of chunks of information one is attempting to process but also on their strength or familiarity.     

嬗变与不变:华夏女神谱系在道教的成立及其文化意蕴

女神崇拜是世界各古老民族共有的一种文化现象.通过对《山海经》《墉城集仙录》《历世真仙体道通鉴后集》等经籍的整理,可初步分离出独立的中华女神谱.在上古神话中,以女娲和西王母为代表的众女神母养群品、教化众生,女神谱系已略具雏形.道教继承了史前女神崇拜,形成了以西王母为尊、墉城为治,以昆仑——上清系为主脉,并融摄民俗女神和历...     

亲社会行为倾向的年龄差异:共情关怀和人际信任的链式中介效应

全球老龄化浪潮正在来临,亲社会行为倾向的年龄差异受到广泛关注。基于第六次世界价值观调查数据集,运用39887个全球成年样本对全球人口亲社会行为倾向的年龄差异进行检验,并探究年龄通过共情关怀和人际信任影响亲社会行为的中介机制。结果表明:全球范围内,年龄显著正向影响亲社会行为倾向,共情关怀不存在显著的年龄差异,人际信任在年龄和亲社会行为倾向之间起显著的中介效应。研究结果对考察亲社会行为倾向的年龄差异及其作用机制具有重要理论价值和实践意义。

初中生依恋风格与欺凌保护行为的关系：社会支持和欺凌应对效能的链式中介作用

为考察初中生依恋风格与欺凌保护行为的关系,同时探讨社会支持和欺凌应对效能的链式中介作用,采用问卷法对565名初中生进行调查。结果发现：（1）依恋焦虑与欺凌保护行为呈显著正相关,依恋回避与欺凌保护行为呈显著负相关;（2）社会支持和欺凌应对效能在依恋回避与欺凌保护行为之间起链式中介作用。若要增加依恋回避初中生的欺凌保护行为,应注重为其提供社会支持,提升欺凌应对效能。     

The generalization of deliberative and automatic behavior: The role of procedural knowledge and affective reactions

Individuals’ goal-directed activity in one situation can affect their behavior in a later, ostensibly unrelated situation. This effect can depend on whether the latter behavior is also goal-directed or is performed automatically. Three studies showed that participants’ rate of speaking in the course of performing a speech shadowing task has a positive influence on the speed with which they later complete an ostensibly unrelated marketing survey. Furthermore, when participants’ attention is called to the goal of working rapidly on the survey, the effect of their past behavior depends on their perception of the goal's desirability. When the time to complete the survey is not mentioned, however, participants’ speed of working on the survey is influenced by their speed of speaking in the earlier situation without their awareness and it does not depend on the desirability of the goal with which their behavior is associated. An additional experiment showed that the relative impact of goal-directed and automatic processes also depends on the cognitive resources that people have available to construe the evaluative implications of their decisions.     

Role of the NO/sGC/PKG signaling pathway of hippocampal CA1 in morphine-induced reward memory

Evidence suggests that the nitric oxide (NO)/soluble guanylyl cyclase (sGC)/cGMP dependent protein kinase (PKG) signaling pathway plays a key role in memory processing, but the actual participation of this signaling cascade in the hippocampal CA1 during morphine-induced reward memory remains unknown. In this study, we investigated the role of the NO/sGC/PKG signaling pathway in the CA1 on morphine-induced reward memory using a conditioned place preference (CPP) paradigm. We found that rats receiving an intraperitoneal (i.p.) injection of 4mg/kg morphine exhibited CPP, whereas rats treated with only 0.2mg/kg morphine failed to produce CPP. Intra-CA1 injection of the neuronal NO synthase (nNOS) inhibitor 7-NI, the sGC inhibitor ODQ or the PKG inhibitor Rp-8-Br-PET-cGMPS had no effect on the acquisition of CPP by 4mg/kg morphine. Intra-CA1 injection of 7-NI blocked the consolidation of CPP induced by 4mg/kg morphine, and this amnesic effect of 7-NI was mimicked by ODQ and Rp-8-Br-PET-cGMPS. Intra-CA1 injection of the NOS substrate L-arg or the sGC activator YC-1 with an ineffective dose of morphine (0.2mg/kg, i.p.) elicited CPP. This response induced by L-arg or YC-1 was reversed by pre-microinjection of Rp-8-Br-PET-cGMPS in the CA1. These results indicated that the activation of the NO/sGC/PKG signaling pathway in the CA1 is necessary for the consolidation of morphine-related reward memory.     

背景性质对7-10岁自闭症谱系障碍儿童面孔搜索与加工的作用

为了考察背景性质对ASD者搜索面孔的影响,设计两个眼动实验任务,要求14名7~10岁ASD儿童和20名同年龄正常儿童观看图片。实验一采用将面孔嵌入风景图片中引起语义不一致的刺激;实验二采用含有面孔的无意义背景乱序图片刺激。结果发现：（1）面孔与背景语义不一致并不能促进ASD儿童对面孔的搜索;（2）乱序背景对ASD儿童面孔搜索与加工没有产生干扰作用,但使正常儿童的搜索时间变长;（3）一旦觉察到面孔后,ASD儿童对面孔的注视时间少于正常儿童。表明正常儿童对面孔的搜索与加工受背景性质的影响,而ASD儿童不受背景性质的影响;一旦发现面孔,ASD儿童的注意维持较短,但面孔加工模式与正常儿童相似。
