为探讨以性别与专业构成的交叉分类群体的理科性别刻板印象,研究采用了内隐联想测验和自我报告两种方式,分别从内隐和外显两个加工层面对其予以考察.结果发现,内隐层面上四类交叉分类群体都存在理科性别刻板印象,但外显层面上只有理科男性、 文科男性和文科女性存在该刻板印象,而理科女性不存在.该结果表明理科性别刻板印象非常顽固,即使...  相似文献

道德外语效应(Moral Foreign Language effect)是指人们的道德判断在外语条件下发生改变的现象,自该效应提出以来,其背后的机制一直都是研究的热点。道德外语效应的解释机制主要有审慎加工增强、情绪反应减少和道德规范联结的减弱等。本文对三种影响机制进行了探讨,发现情绪、道德规范和外语水平对道德判断可能会产生影响。同时,本文指出未来可以从自我控制、认知启动效应、消极情绪启动效应及道德规范与外语水平之间的关系进行研究和探讨。  相似文献

民国时期,在全国范围内普遍出现了传统乡绅阶层劣化的现象,这是传统社会控制结构失衡之后的特殊产物.本文以苏北地区为例,对近代苏北乡绅劣化的成因进行分析,认为主要因素有四,即:19世纪中期以来的中央政权控制力的下降、传统乡村绅士阶层的分化、乡村权威的武化和封闭落后的地理环境等.  相似文献

Matching the emotional expressions of pairs of face photos was slower with pixelated and blurred photos than with original, untransformed photos. Matching the identities of the same face pairs was unaffected by pixelation and blurring. Because pixelation and blurring degrade higher spatial frequencies carrying edge-based information that define feature shape more than lower frequencies carrying configural properties, these findings converge with findings for line drawings and negative photos in showing that expression and face recognition processes differ in their reliance on edge-based and configural information.  相似文献

Emerging evidence suggests that a traumatic brain injury (TBI) in childhood may disrupt the ability to abstract the central meaning or gist-based memory from connected language (discourse). The current study adopts a novel approach to elucidate the role of immediate and working memory processes in producing a cohesive and coherent gist-based text in the form of a summary in children with mild and severe TBI as compared to typically developing children, ages 8-14 years at test. Both TBI groups showed decreased performance on a summary production task as well as retrieval of specific content from a long narrative. Working memory on n-back tasks was also impaired in children with severe TBI, whereas immediate memory performance for recall of a simple word list in both TBI groups was comparable to controls. Interestingly, working memory, but not simple immediate memory for a word list, was significantly correlated with summarization ability and ability to recall discourse content.  相似文献

Ritualized behavior, intuitively recognizable by its stereotypy, rigidity, repetition, and apparent lack of rational motivation, is found in a variety of life conditions, customs, and everyday practices: in cultural rituals, whether religious or non-religious; in many children's complicated routines; in the pathology of obsessive-compulsive disorders (OCD); in normal adults around certain stages of the life-cycle, birthing in particular. Combining evidence from evolutionary anthropology, neuropsychology and neuroimaging, we propose an explanation of ritualized behavior in terms of an evolved Precaution System geared to the detection of and reaction to inferred threats to fitness. This system, distinct from fear-systems geared to respond to manifest danger, includes a repertoire of clues for potential danger as well as a repertoire of species-typical precautions. In OCD pathology, this system does not supply a negative feedback to the appraisal of potential threats, resulting in doubts about the proper performance of precautions, and repetition of action. Also, anxiety levels focus the attention on low-level gestural units of behavior rather than on the goal-related higher-level units normally used in parsing the action-flow. Normally automatized actions are submitted to cognitive control. This "swamps" working memory, an effect of which is a temporary relief from intrusions but also their long-term strengthening. Normal activation of this Precaution System explains intrusions and ritual behaviors in normal adults. Gradual calibration of the system occurs through childhood rituals. Cultural mimicry of this system's normal input makes cultural rituals attention-grabbing and compelling. A number of empirical predictions follow from this synthetic model.  相似文献

Few sex differences in regret or counterfactual thinking are evident in past research. The authors discovered a sex difference in regret that is both domain-specific (i.e., unique to romantic relationships) and interpretable within a convergence of theories of evolution and regulatory focus. Three studies showed that within romantic relationships, men emphasize regrets of inaction over action (which correspond to promotion vs. prevention goals, respectively), whereas women report regrets of inaction and action with equivalent frequency. Sex differences were not evident in other interpersonal regrets (friendship, parental, sibling interactions) and were not moderated by relationship status. Although the sex difference was evident in regrets centering on both sexual and nonsexual relationship aspects, it was substantially larger for sexual regrets. These findings underscore the utility of applying an evolutionary perspective to better understand goal-regulating, cognitive processes.  相似文献

一种新的智力观--塞西的智力生物生态学模型述评   总被引:1,自引:1,他引:0  
丁芳  李其维  熊哲宏 《心理科学》2002,25(5):541-543
美国心理学教授塞西在对传统智力心理测量学理论批评的基础上于1990年提出了信息加工取向的智力的生物生态学模型。这一模型主要有四个基本假设,即智力是一个多种资源系统;生物潜能与环境力量的相互作用;适宜的“最近过程”是智力发展的“引擎”;把“动机”整合到智力发展中。塞西智力的生物生态学模型为我们揭示人的智力的本质提供了一个新的视角。  相似文献

Skilled readers of Chinese participated in sorting and visual search experiments. The sorting results showed that under conditions of conflicting information about structure and component, subjective judgments of the visual similarity among characters were based on the characters' overall configurations (i.e., structures) rather than on the common components the characters possessed. In visual search, both structure and component contributed to the visual similarity reflected by the search efficiency. The steepest search slopes (thus the most similar target-distractor pairs) were found when the target and the distractor characters had the same structure and shared 1 common component, compared with when they had different structures and/or shared no common components. Results demonstrated that character structure plays a greater role in the visual similarity of Chinese characters than has been considered.  相似文献

The emergence of competing modules in bilingualism   总被引:5,自引:0,他引:5  
How does the brain manage to store and process multiple languages without encountering massive interference and transfer? Unless we believe that bilinguals live in two totally unconnected cognitive worlds, we would expect far more transfer than actually occurs. However, imaging and lesion studies have not provided consistent evidence for the strict neuronal separation predicted by the theory of modularity. We suggest that emergentist theory offers a promising alternative. It emphasizes the competitive interplay between multiple languages during childhood and by focusing on the dual action of competition and entrenchment, avoids the need to invoke a critical period to account for age of acquisition effects in second-language learning. This view instantiates the motto formulated by Elizabeth Bates that 'modules are made, not born.'  相似文献
