Human infants, just a few days of age, are known to prefer attractive human faces. We examined whether this preference is human-specific. Three- to 4-month-olds preferred attractive over unattractive domestic and wild cat (tiger) faces (Experiments 1 and 3). The preference was not observed when the faces were inverted, suggesting that it did not arise from low-level image differences (Experiments 2 and 3). In addition, the spontaneous preference for attractive tiger faces influenced performance in a recognition memory task involving attractive versus unattractive tiger face pairings (Experiment 4). The findings suggest that infant preference for attractive faces reflects the activity of general processing mechanisms rather than a specific adaptation to mate choice. 相似文献

The present study examined the developmental origin of 'blue lies', a pervasive form of lying in the adult world that is told purportedly to benefit a collective. Seven, 9-, and 11-year-old Chinese children were surreptitiously placed in a real-life situation where they decided whether to lie to conceal their group's cheating behavior. Children were also assessed in terms of their willingness in hypothetical situations to endorse lying or truth-telling that benefits a collective but at the same time harms an individual. Results showed that as age increased, children became more inclined to endorse lying in the name of the collective good, and to tell lies for their group themselves. Furthermore, children's endorsement about blue lies in hypothetical situations predicted their actual lying behavior. 相似文献

组织变革的多样性管理:一种系统性框架 总被引:1,自引:0,他引:1
组织的变革是组织发展的一个关键。但是研究表明,对于组织变革的管理相对比较薄弱.而在方法论上的一些探索有助于解决组织变革管理薄弱的问题。本文将简要阐述在组织变革管理中所应用的一些方法及其不足,并就系统观以及与组织变革管理相关的问题作一些讨论。在组织变革过程中系统性框架的应用将有助于解决组织多纬度变革的差异及其多纬度变革间的相互作用问题。因此.系统性框架对于理解和管理组织的变革是非常有作用的。 相似文献

The extent to which readers can exert strategic control over oral reading processes is a matter of debate. According to the
pathway control hypothesis, the relative contributions of the lexical and nonlexical pathways can be modulated by the characteristics
of the context stimuli being read, but an alternative time criterion model is also a viable explanation of past results. In
Experiment 1, subjects named high- and low-frequency regular words in the context of either low-frequency exception words
(e.g., pint) or nonwords (e.g., flirp). Frequency effects (faster pronunciation latencies for high-frequency words) were attenuated in the nonword context, consistent
with the notion that nonwords emphasize the characteristics of the frequency-insensitive nonlexical pathway. Importantly,
we also assessed memory for targets, and a similar attenuation of the frequency effect in recognition memory was observed
in the nonword condition. Converging evidence was obtained in a second experiment in which a variable that was more sensitive
to the nonlexical pathway (orthographic neighborhood size) was manipulated. The results indicated that both speeded pronunciation
performance and memory performance were relatively attenuated in the low-frequency exception word context in comparision with
the nonword context. The opposing influences of list context type for word frequency and orthographic neighborhood size effects
in speeded pronunciation and memory performance provide strong support for the pathway control model, as opposed to the time
criterion model. 相似文献

The present study examined children's and adults' categorization and moral judgment of truthful and untruthful statements. 7‐, 9‐ and 11‐year‐old Chinese children and college students read stories in which story characters made truthful or untruthful statements and were asked to classify and evaluate the statements. The statements varied in terms of whether the speaker intended to help or harm a listener and whether the statement was made in a setting that called for informational accuracy or politeness. Results showed that the communicative intent and setting factors jointly influence children's categorization of lying and truth‐telling, which extends an earlier finding (Lee & Ross, 1997) to childhood. Also, we found that children's and adults' moral judgments of lying and truth‐telling were influenced by the communicative intent but not the setting factor. The present results were discussed in terms of Sweetser's (1987) folkloristic model of lying. Copyright © 2009 John Wiley & Sons, Ltd. 相似文献

问卷长度与作答型式的关系 总被引:1,自引:0,他引:1
从心理计量的观点来看,作答型式对心理测验及研究采用的问卷的信度和效度,均会构成严重威协。本文介绍了一些常见的作答型式及用来控制作答型式的传统统计方法。随后,我们指出由于这些传统统计方法都预先假定作答型式是稳定不变的,其效度便有疑问了;因为本文报告的研究证实了随着问卷长度的递增,作答型式会趋于刻板和不极端。因此,我们建议研究者在设计研究时,应尽量避免使用冗长的问卷。 相似文献

Adults are sensitive to the physical differences that define ethnic groups. However, the age at which we become sensitive to ethnic differences is currently unclear. Our study aimed to clarify this by testing newborns and young infants for sensitivity to ethnicity using a visual preference (VP) paradigm. While newborn infants demonstrated no spontaneous preference for faces from either their own- or other-ethnic groups, 3-month-old infants demonstrated a significant preference for faces from their own-ethnic group. These results suggest that preferential selectivity based on ethnic differences is not present in the first days of life, but is learned within the first 3 months of life. The findings imply that adults' perceptions of ethnic differences are learned and derived from differences in exposure to own- versus other-race faces during early development. 相似文献

多巴胺活性与攻击相关的脑功能活动呈倒U型关系。本研究对1044名汉族青少年(初次测评时M age=13.32±0.49岁,50.2%女生)的攻击行为进行间隔一年的两次测评,采用多基因累积分范式考察多巴胺系统的多基因功能积分与青少年攻击行为间的关系以及母亲消极教养的调节作用。结果发现,多巴胺系统多基因累积分二次项与母亲消极教养交互影响两个时间点的青少年攻击行为:在较高母亲消极教养条件下,携带较多或较少低多巴胺活性相关等位基因的青少年表现出高水平的攻击行为,呈U型关系;在较低母亲消极教养条件下,多基因累积分二次项与青少年的攻击行为关系不显著。本研究为多巴胺系统基因的联合效应与母亲消极教养调节青少年攻击行为的基因作用机制提供证据。 相似文献
