Monolingual but not bilingual infants demonstrate racial bias in social cue use

Bilingualism exerts early and pervasive effects on cognition, observable in infancy. Thus far, investigations of infant bilingual cognition have focused on sensitivity to visual memory, executive function, and linguistic sensitivity. Much less research has focused on how bilingualism impacts processing of social cues. The present study sought to investigate whether bilingualism modulates the expression of one aspect of social processing: early racial bias. Using a gaze‐following paradigm, we investigated whether 18‐ to 20‐month‐old monolingual and bilingual infants favored their own race. Results demonstrated that monolingual infants favored their own race in following a model whose direction of gaze signaled an event. In contrast, bilingual infants demonstrated race‐neutral gaze‐following patterns, relying more heavily on the reliability of the behavior of the model over race. Findings suggest that bilingualism may have protective effects against the early emergence of racial bias.     

I need to be your only friend: the effect of salesperson network centrality on opportunistic behavior

Transaction cost economics can be used to detect opportunistic behavior by one or more actors within a sales network. Using a sample of firms in the medical industry, where the role of salespeople is important, this study examines network centrality as a determinant of a salesperson’s opportunistic behavior in intrafirm relationships. The results indicate that opportunistic behavior is affected differently depending on a salesperson’s relational and positional centralities. While relational centrality decreases opportunistic behavior by providing motivation to protect one’s reputation, positional centrality negatively moderates the effect of relational centrality on opportunistic behavior. However, with a high relational centrality, a salesperson is less likely to be opportunistic when she or he is low in positional centrality than when her or his positional centrality is high.     

Examining the testing effect with open‐ and closed‐book tests

Two experiments examined the testing effect with open‐book tests, in which students view notes and textbooks while taking the test, and closed‐book tests, in which students take the test without viewing notes or textbooks. Subjects studied prose passages and then restudied or took an open‐ or closed‐book test. Taking either kind of test, with feedback, enhanced long‐term retention relative to conditions in which subjects restudied material or took a test without feedback. Open‐book testing led to better initial performance than closed‐book testing, but this benefit did not persist and both types of testing produced equivalent retention on a delayed test. Subjects predicted they would recall more after repeated studying, even though testing enhanced long‐term retention more than restudying. These experiments demonstrate that the testing effect occurs with both open‐ and closed‐book tests, and that subjects fail to predict the effectiveness of testing relative to studying in enhancing later recall.

Preference for attractive faces in human infants extends beyond conspecifics

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.     

Lying in the name of the collective good: a developmental study

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.     

组织变革的多样性管理:一种系统性框架

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。     

Pathway control in visual word processing: Converging evidence from recognition memory

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.     

Children's and adults' conceptualization and evaluation of lying and truth‐telling

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.     

问卷长度与作答型式的关系

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。
