6~9岁儿童特质观与其人格特质的关系   总被引:1,自引:0,他引:1  
杨丽珠  高雯 《心理科学》2007,30(4):839-843
为考察特质观与稳定的行为方式之间的关系,采用情境故事法和问卷法分别对180名6~9岁儿童进行了特质稳定性理解的个别测查和人格特质的教师评定。结果发现,持三种不同特质观(实体论、中间论、渐变论)的6~9岁儿童开始在认真有恒、自制稳重、聪慧性、开朗活泼和同情利他五种人格特质行为上表现出显著差异;6~9岁儿童的特质观能够预测以上五种人格特质,丽儿童“开朗插泼”和“聪慧性”特质行为的线性组合是预测儿童特质观的最佳指标。这些研究结论有助于说明关于特质的认知在调解和制约个体稳定的行为理解和反应中的重要作用,验证了人格认知流派的观点;支持了认知与人格之间交互作用的理论假设;对于解释年幼儿童发展中的不适应问题具有一定的意义。  相似文献

Relative size judgments were collected for two objects at 30.5 m and 23.8 m from the observer in order to assess how performance depends on the relationship between the size of the objects and the eye level of the observer. In three experiments in an indoor hallway and in one experiment outdoors, accuracy was higher for objects in the neighborhood of eye level. We consider these results in the light of two hypotheses. One proposes that observers localize the horizon as a reference for judging relative size, and the other proposes that observers perceive the general neighborhood of the horizon and then employ a height-in-visual-field heuristic. The finding that relative size judgments are best around the horizon implies that information that is independent of distance perception is used in perceiving size.  相似文献

Changes in perception during space missions are usually attributed to microgravity. However, additional factors, such as spatial confinement, may contribute to changes in perception. We tested changes in scene perception using a boundary extension (BE) paradigm during a 105-day Earth-based space-simulation study. In addition to the close-up/wide-angle views used in BE, we presented two types of scenes based on the distance from the observer (proximal/distant scenes). In crew members (n = 6), we found that BE partly increased over time, but the size of BE error did not change in the control group (n = 22). We propose that this effect is caused by an increasing BE effect in stimuli that depict distant scenes and is related to spatial confinement. The results might be important for other situations of spatial confinement with restricted visual depth (e.g., submarine crew, patients confined to a bed). Generally, we found a larger BE effect in proximal scenes compared with the distant scenes. We also demonstrated that with no feedback, subjects preserve the level of the BE effect during repeated measurements.  相似文献

The household registration system (Hukou) implemented by the Chinese government divides the Chinese society into two groups: urban residents and rural residents. Since the 1980s, millions of rural residents have migrated to cities without official permission. In this paper, we investigate urban residents' subtle prejudice towards rural‐to‐urban migrants. Specifically, the impacts of urban residents' socioeconomic status (SES) and their perception of migrants' adaptation styles are examined. A sample including 457 Chinese urban residents is taken from four cities in China. Educational and occupational levels are used to indicate urban residents' SES. Four adaptation styles (integration, assimilation, separation and marginalization) are manipulated by using vignettes. The results show that SES has a negative impact on urban residents' subtle prejudice. This link is further moderated by urban residents' perceptions of migrants' adaptations: the negative effect of SES on subtle prejudice holds only under a perception of integration or assimilation and disappears under a perception of separation or marginalization.

The effect of chamber gas pressure on the amorphicity of Al85Ni5Y10 alloy was studied for the melt-spinning process. The amorphicity of as-quenched ribbons was characterized by X-ray diffraction (XRD) and differential scanning calorimetry (DSC). The chamber atmosphere pressure is crucial to the cooling rate of melt spinning. At high vacuum, at pressure less than 0.001?atm, fully crystalline fragments are obtained. Monolithic amorphous ribbons were only obtained at a gas pressure of 0.1?atm, 0.2?atm or higher. The extended contact length between ribbons and the copper wheel contributes to the high cooling rate of melt spinning in Al-based glass forming alloys; that is supported by images recorded by a high-speed camera. Higher chamber pressure increases contact length between ribbons and the wheel, which is qualitatively elucidated by Bernoulli's equation.  相似文献

Work function (WF) can be measured using the Kelvin probe (KP) technique to characterize surface behavior of micro/nanostructures grown on substrates such as metals or semiconductors. However, for such micro/nanostructures, substrates with different WF can strongly affect the measurements if they are exposed directly to face the Kevin probe tip. In this article, a model is proposed to investigate the WF of sparse ZnO nanorods grown on an Si substrate. It is demonstrated that theoretical results from the model are consistent with experimental observations performed using a KP system.  相似文献

Taking sides is one of the reactions available to third parties in handling a dispute. From the perspective of individual differences, this study was aimed at identifying lay third parties' motives for side taking and exploring their relations with the Big Five personality traits. We tested our assumptions using three samples: A Dutch student sample (n = 111), a Dutch employee sample (n = 101) and a Chinese student sample (n = 124). The findings revealed four types of side‐taking motives: Moral, relational, reward‐approaching and sanction‐avoiding motives. The results also showed that individuals' personality traits were relevant to the four types of side‐taking motives: Agreeableness was associated with the relational motive for side taking, and intellectual autonomy was associated with the reward‐approaching motive, the sanction‐avoiding motive and the relational motive for side taking. Implications and explanations of these findings are discussed. Copyright © 2010 John Wiley & Sons, Ltd.  相似文献

The study aims to help characterize the sort of structures about which people can acquire unconscious knowledge. It is already well established that people can implicitly learn n-grams (chunks) and also repetition patterns. We explore the acquisition of unconscious structural knowledge of symmetry. Chinese Tang poetry uses a specific sort of mirror symmetry, an inversion rule with respect to the tones of characters in successive lines of verse. We show, using artificial poetry to control both n-gram structure and repetition patterns, that people can implicitly learn to discriminate inversions from non-inversions, presenting a challenge to existing models of implicit learning.  相似文献

Using Reidenbach and Robin's Multidimensional Ethics Scale, this study investigated the relationships between background variables and students' ethical evaluations, judgments, and behavioral intentions using 3 scenarios involving dilemmas related to academic dishonesty. The sample included 436 master's students and 142 doctoral students. The study found that the participants used a combination of ethical philosophies to make ethical decisions. The respondents judged improper citations more harshly than acts of inappropriate authorship or the falsification of data. The doctoral students generally considered behaviors related to plagiarism and falsification to be more unethical than the master's students did, though no gender differences were found.  相似文献
