正字法深度对汉族、维吾尔族大学生汉字词命名的影响

汉字的多音字数量众多, 种类复杂, 为维吾尔族学生学习汉语带来了困难。通过两个实验, 考察正字法深度对汉族大学生和维吾尔族大学生的汉字词命名的影响。结果表明, 无论是命名单字词还是命名双字词, 维吾尔族学生的反应时均比汉族学生显著长。对单字词, 两个民族被试的命名时间均受汉字的正字法深度和词频影响, 被试命名多音字的时间显著长于命名单音字, 命名低频字的时间显著长于命名高频字。对双字词, 两个民族被试的命名时间存在着词频与正字法深度的交互作用：对高频词, 汉族学生对由多音字组成的词与由单音字组成的词的反应时差异不显著, 维吾尔族学生对由多音字组成的词的反应时显著长于对由单音字组成的词; 对低频词, 汉族学生对由多音字组成的词的反应时显著长于对由单音字组成的词, 维吾尔族学生对由多音字组成的词与由单音字组成的词的反应时差异不显著。整个研究表明, 正字法深度对两个民族大学生的汉字词命名的影响具有不同模式。所以如此, 与两个民族的母语特点、词汇获得年龄、语言熟练程度和语言加工方式不同有关。     

What you are confident of determines your choices in context: Confidence in yourself versus in your ability

The notion that consumers' preference is constructed by decision context is well established. Two of such salient manifestations are compromise effect and attraction effect. Although literature has explored the moderators of these effects from the perspective of a decision maker, little is known about whether a significant difference exists between the effects of individual differences as a situational state and as a stable personality. This article approaches this question by examining how specific self‐confidence and general self‐confidence shape consumer's preference for context options. Four studies find that compromise effect is greater for consumer with high specific self‐confidence, whereas attraction effect is greater for consumer with low specific self‐confidence. The two context effects are greater for consumers with low general self‐confidence only in the presence of social influence. In addition, low (vs. high) general self‐confidence strengthens (vs. weakens) the impact of specific self‐confidence on context effects under this condition. This article concludes by discussing the theoretical and practical implications of the findings.     

句子语境中语义联系启动作用的研究

通过对比研究正序和乱序两种句子语境对目标词加工的不同影响,来探讨句子语境中语义联系启动作用及作用点问题。实验一采用词汇命名任务研究发现,句法成分影响命名任务,句法违反对命名任务产生较大的抑制作用。语义违反则对命名任务没有产生显著的抑制作用。实验二利用词汇决定任务发现,词序影响决定任务,乱序对词汇决定产生很大的抑制作用。语义违反对决定任务地产生较大的抑制作用。结果表,中义联系启动是短暂的,它的保持和传递需要句法成分的支持。     

句子语境中语义联系效应和句法效应的研究

通过对比研究句子语境中句法成分和语义联系对目标词加工的不同影响,来探讨句子语境的作用机制和作用点问题。实验一采用词汇命名任务研究发现,句法违反对词汇命名会产生抑制作用,而语义违反对词汇命名却没有发现抑制作用。实验二利用词汇决定任务发现,句法和语义成分影响词汇决定任务,句法违反和语义违反对词汇决定任务均会产生抑制作用。结果表明,句子语境加工中,对内容词语义整合过程中存在一个句法成分的独立加工水平。     

弱势群体判断对不同价值语义启动下道德判断的调节效应研究

通过行为实验探讨了公平正义和人文关怀这两种基本道德价值的语义启动对涉及弱势群体的道德两难问题判断的影响。研究结果表明,不同道德价值语义启动对道德判断有显著影响,具体表现为：在公平正义启动状态下,人们的道德判断不会对弱势者有明显的道德宽容偏向。当个体处于恻隐关怀启动状态时则会出现明显的道德判断弱势者效应,即对弱势群体的道德判断存在显著的宽容偏向。进一步的检验表明弱势群体判断在道德价值语义启动与道德判断中起着显著的调节作用。本研究不仅从实证的角度证实了道德价值语境在道德判断中的重要性。同时文章还指出在面对重大社会负性事件时,政府、社会媒体、学术界应该呈现怎样的道德价值语境是一个既具有突出现实性和重要理论性的问题。     

嵌入于社会情境的工作重塑

工作重塑实质上是一种情境性的主动性行为。基于已有研究成果,首先系统归纳工作重塑与社会情境因素之间关系的4种研究视角,即社会情境是工作重塑的目标、社会情境因素是工作重塑的组成部分、社会情境因素影响工作重塑、社会情境因素为工作重塑设立边界条件。此外,梳理并讨论社会情境因素影响工作重塑的内在机制以及社会情境因素与个体特征的交互对于工作重塑的影响、工作重塑在特定情境中的有效性两方面的研究。在此基础上,结合其他相关变量的研究现状对嵌入于社会情境的工作重塑的未来研究进行展望,包括探索工作重塑对他人的影响、探索团队工作重塑驱动个体工作重塑的多重路径、探索社会情境影响工作重塑的内在机制、探索社会情境与个体特征的交互如何影响工作重塑,以及探讨基于中国社会情境的工作重塑的有效性。     

Association of polymorphisms in BDNF, MTHFR, and genes involved in the dopaminergic pathway with memory in a healthy Chinese population

The contribution of genetic factors to the memory is widely acknowledged. Research suggests that these factors include genes involved in the dopaminergic pathway, as well as the genes for brain-derived neurotrophic factor (BDNF) and methylenetetrahydrofolate reductase (MTHFR). The activity of the products of these genes is affected by single nucleotide polymorphisms (SNPs) within the genes. This study investigates the association between memory and SNPs in genes involved in the dopaminergic pathway, as well as in the BDNF and MTHFR genes, in a sample of healthy individuals. The sample includes 134 Taiwanese undergraduate volunteers of similar cognitive ability. The Chinese versions of the Wechsler Memory Scale (WMS-III) and Wechsler Adult Intelligence Scale (WAIS-III) were employed. Our findings indicate that the BDNF Met66Val polymorphism and dopamine receptor D3 (DRD3) Ser9Gly polymorphism are associated significantly with long-term auditory memory. Further analysis detects no significant associations in the other polymorphisms and indices. Future replicated studies with larger sample sizes, and studies that consider different ethnic groups, are encouraged.     

Unconscious Familiarity and Local Context Effects on Low-Level Face Processing: A Reconstruction Hypothesis

A common view in face recognition research holds that there is a stored representation specific to each known face. It is also posited that semantic or memory-based information cannot influence low-level face processing. The two experiments reported in this article investigate the nature of this representation and the flow of face information processing. Participants had to search for a particular primed face among other faces. In Experiment 1, the search was done in a context where distractors had either a different degree of fame or the same degree of fame. In Experiment 2, the target face was primed either with semantic information or without any information. Both experiments demonstrated that increasing the display set size lengthened face detection time. However, the lengthening was a function of face fame. The search context also had an effect on the slope of the famous face detection. The results are explained in terms of the idea that face representations are reconstructed and that high- and low-level information are integrated into the processing. The integration process is not a conscious one.     

Is it dangerous? The role of an emotional visual search strategy and threat-relevant training in the detection of guns and knives

Counter-terrorism strategies rely on the assumption that it is possible to increase threat detection by providing explicit verbal instructions to orient people's attention to dangerous objects and hostile behaviours in their environment. Nevertheless, whether verbal cues can be used to enhance threat detection performance under laboratory conditions is currently unclear. In Experiment 1, student participants were required to detect a picture of a dangerous or neutral object embedded within a visual search display on the basis of an emotional strategy ‘is it dangerous?’ or a semantic strategy ‘is it an object?’. The results showed a threat superiority effect that was enhanced by the emotional visual search strategy. In Experiment 2, whilst trainee police officers displayed a greater threat superiority effect than student controls, both groups benefitted from performing the task under the emotional than semantic visual search strategy. Manipulating situational threat levels (high vs. low) in the experimental instructions had no effect on visual search performance. The current findings provide new support for the language-as-context hypothesis. They are also consistent with a dual-processing account of threat detection involving a verbally mediated route in working memory and the deployment of a visual template developed as a function of training.     

非暴力视频游戏中竞争情境对玩家合作倾向和攻击倾向的影响

使用中性视频游戏和亲社会视频游戏，采用单次双人给予倾向困境任务和辣酱范式分别测量被试的合作倾向和攻击倾向，旨在探究竞争性视频游戏情境对玩家合作倾向和攻击倾向的影响。结果发现：（1）在对合作倾向的影响上，无论是玩中性视频游戏还是亲社会视频游戏，竞争情境相比单人情境均能显著降低玩家的合作倾向；（2）在对攻击倾向的影响上，玩中性视频游戏，竞争情境相比单人情境能显著提高玩家的攻击倾向；但玩亲社会视频游戏，竞争情境与单人情境对玩家攻击倾向的影响差异不显著。本研究表明，游戏情境是影响玩家行为倾向的重要因素之一，在非暴力视频游戏中竞争情境对玩家行为倾向会产生消极影响，亲社会视频游戏在一定程度上能抑制竞争情境的消极效应。
