初中生社会比较在成就目标与学业自我效能感之间的中介效应

采用成就目标定向、社会比较和学业自我效能感三个量表,以724名初中生为被试,对社会比较在成就目标与学业自我效能感之间的中介作用进行了考察。结果表明：（1）除对学习能力自我效能感产生直接影响外,掌握接近目标会通过上行比较、成绩接近目标会通过上行/下行比较间接地影响学习能力自我效能感;（2）掌握接近目标、成绩接近目标和成绩回避目标不仅会对学习行为自我效能感产生直接影响,还会通过下行比较对其产生间接影响。说明成就目标可以通过直接和间接两种不同的方式影响学业自我效能感。

Working memory and number line representations in single-digit addition: Approximate versus exact,nonsymbolic versus symbolic

How do kindergarteners solve different single-digit addition problem formats? We administered problems that differed solely on the basis of two dimensions: response type (approximate or exact), and stimulus type (nonsymbolic, i.e., dots, or symbolic, i.e., Arabic numbers). We examined how performance differs across these dimensions, and which cognitive mechanism (mental model, transcoding, or phonological storage) underlies performance in each problem format with respect to working memory (WM) resources and mental number line representations. As expected, nonsymbolic problem formats were easier than symbolic ones. The visuospatial sketchpad was the primary predictor of nonsymbolic addition. Symbolic problem formats were harder because they either required the storage and manipulation of quantitative symbols phonologically or taxed more WM resources than their nonsymbolic counterparts. In symbolic addition, WM and mental number line results showed that when an approximate response was needed, children transcoded the information to the nonsymbolic code. When an exact response was needed, however, they phonologically stored numerical information in the symbolic code. Lastly, we found that more accurate symbolic mental number line representations were related to better performance in exact addition problem formats, not the approximate ones. This study extends our understanding of the cognitive processes underlying children's simple addition skills.     

Proficiency in a second language influences the processing of number words

We evaluated whether proficiency in a second language (L2) influenced the processing of numerical information. In Experiment 1, two groups of German/English bilinguals, one less proficient in English (L2) and the other more proficient in L2, performed two-digit number comparison tasks while the unit–decade compatibility was evaluated. All participants presented compatibility effect with Arabic digits regardless of their L2 proficiency. However, when bilinguals with less proficiency in L2 performed verbal number comparison tasks they showed regular compatibility effect in German and reverse compatibility effect in English, whereas more proficient bilinguals did not show compatibility effects in either German or English. In Experiment 2, the same pattern of results was obtained with highly proficient bilinguals after controlling their working memory span. These results indicate that L2 proficiency influences the processing of two-digit number words.     

Race for Power in Public Good Games with Unequal,Unstable Punishment Power

Decentralized punishment can maintain contributions to a public good at a high level. This positive effect holds even for situations involving inequality in punishment power, meaning that the relative costs for punishment differ between persons. We extend this line of research by examining the additional influence of instability of and thus potential competition for punishment power in public good experiments. As in previous research, inequality is operationalized by assigning the role of a ‘strong player’ to one group member, who can punish others at a reduced cost compared to other players. Instability is operationalized by the fact that the role assignment can change across rounds and is contingent on behavior in previous rounds. Three experiments show that under unequal, unstable (punishment‐) power, individuals behave more competitively and engage in a race for power resulting in detrimental effects for the group. Specifically, we find that (i) unstable power goes along with a disproportionate use of punishment; (ii) not inequality by itself but rather the combination of instability and inequality causes this effect; and (iii) this excessive use of punishment is found not only when the role of the strong player is assigned to individuals who previously behaved rather selfishly but also when prosocial behavior leads to the top, speaking for a generalizability of our findings. Implications for organizational settings are discussed. Copyright © 2016 John Wiley & Sons, Ltd.     

Cross‐cultural comparison of seven morningness and sleep–wake measures from Germany,India and Slovakia

Morningness–eveningness or circadian typology can be viewed as an interesting aspect of individual differences. Morningness–eveningness is a preference for a given time of day for physical or mental performance, but also reflects aspects of affect. Here, we used seven different measures to assess differences in morningness–eveningness between Germany, Slovakia and India. The hypothesis was that Indians should be earliest chronotypes, followed by Slovakia and then Germany, because of higher temperatures in India, and the fact that Slovakia is located farther east compared to Germany. We applied the Composite Scale of Morningness (CSM), the Circadian Energy Scale (CIRENS), the CAEN Chronotype Questionnaire (CCQ), and habitual sleep–wake variables to calculate sleep duration, midpoint of sleep and social jetlag. Sample sizes were N = 300 (Germany), N = 482 (Slovakia) and N = 409 (India). Country had the strongest influence on morningness–eveningness. Germans were latest chronotypes and differed in all seven measures from Indians but differed from Slovakians only in the energy level at the evening and midpoint of sleep. Slovakians and Indians differed in all measures but the energy level (CIRENS). Women scored higher on the CSM, lower on CIRENS, lower on the morningness–eveningness (ME) scale, but higher on distinctness (DI) scale. Women slept longer and had an earlier midpoint of sleep.

大学生现在将来的自我时间比较研究

使用大学生自我概念问卷对200名西南大学在校大二学生实施问卷调查,了解大学生现在与将来自我时间比较的特点。研究结果表明：大学生在自我时间比较中对将来自我的评价显著高于对现在自我的评价;近期将来和远期将来的自我提升除在交际品质维度上有显著差异外,在其他维度上均无显著差异;在重要品质上的自我提升高于在不重要品质上的自我提升,但差异不显著。     

The role of egocentrism and focalism in the emotion intensity bias

People sometimes judge their emotions, preferences, and attitudes to be more intense than those of other people. Two experiments tested whether this emotion intensity bias in direct comparisons results from two non-motivated cognitive processes—egocentrism and focalism. In Study 1, the intensity bias was found even when comparing a friend’s preferences to peers. In Study 2, attention given to own versus other’s preferences, and the referent of the comparison (self or others) were manipulated. Results indicated that attention to others reduced the bias, presumably by reducing egocentrism. Consistent with focalism, the bias also emerged when a friend was the target of comparison, and the bias was eliminated when the self was the referent rather than the target of comparison. In the discussion, we evaluate these accounts in light of some alternative explanations for the intensity bias.
