Production of lexical categories in French children with SLI and in normally developing children matched for MLU

Free speech recording samples of two groups of French SLI children aged 48 and 62 months (matched for MLU, 1.70) and two groups of French normally developing children aged 26 and 36 month (matched for MLU, 3.2) were compared to determine whether they showed a difference in the use of lexical categories. A category-by-category comparison showed few significant differences. For low MLU children, SLI produced significantly fewer infinitives, past participles, copulas, and demonstrative pronouns. For high MLU children, the difference persisted only in past participles use. As for English SLI children, French SLI children were delayed in their acquisition of verbs. However, the differences in the syntactic structure of English and French ruled out a syntactic explanation of the deficit. Phonetic problems seem to decrease with age, so they cannot be the only explanation behind the difficulties of SLI children, which probably involve cognitive problems such as processing limitations.     

From Insult to Injury: Explaining the Impact of Incivility

Previous research has demonstrated that violence, harassment, and discrimination have negative consequences for individual well-being. However, this literature has focused less on subtle forms of mistreatment, such as incivility. The current study addresses this gap by developing and testing a conceptual model of incivility, as experienced in institutions of higher education. A survey of 1,043 university students revealed that over 75% had experienced uncivil behavior from other members of their institution in the prior year. Structural equation analyses suggest that these incivility targets endured psychological distress, dissatisfaction with and disengagement from their institution, and performance decline. We also identified perceptions of injustice and ostracism as key mediators in this process, which operated somewhat differently depending on the formal institutional status of the incivility instigator. Implications for theory and research are discussed.     

Specificity and Abstraction of Examples: Opposite Effects on Fixation for Creative Ideation

Fixation is one of the major obstacles that individuals face in creative idea generation contexts. Several studies have shown that individuals unintentionally tend to fixate to the examples they are shown in a creative ideation task, even when instructed to avoid them. Most of these studies used examples formulated with high level of specificity. However, no study has examined individuals’ creative performance under an instruction to diverge from given examples, when these examples are formulated with a high level of abstraction. In the present study, we show that (a) instructing participants to avoid using common examples when formulated with a high level of specificity increases fixation; whereas (b) instructing participants to avoid such examples while using a more abstract level for stating these common examples—such as a categorization of these examples—mitigates fixation and doubles the number of creative ideas generated. These findings give new insights on the key role of categorization in creative ideation contexts.     

Structural validity and reliability of the Spanish version of the White Bear Suppression Inventory (WBSI) in a sample of the general Spanish population

This paper introduces the validation of the Spanish adaptation of the White Bear Suppression Inventory (WBSI) by Wegner and Zanakos (1994). A sample of 833 people from the general population completed the WBSI along with other questionnaires. The exploratory factor analysis and the confirmatory factor analysis supported a two-factor solution accounting for 51.8% of the cumulative variance. This structure is comprised of the two following factors: unwanted intrusive thoughts (alpha = .87, r = .70) and actions of distraction and suppression of thoughts (alpha = .80, r = .60). Both internal consistency reliability (alpha = .89) and test-retest reliability (r = .71) showed adequate homogeneity, sound consistency, and stability over time. The results are discussed bearing in mind both isolated factors and the possible relationships of the suppression factor with automatic negative thoughts and insomnia.     

La connaissance du gain d’autrui : une incitation au risque ?

This research aims at suggesting a causal model of risk-taking, following the announcement of another player's gains in a gamble with elementary characteristics. Risk-taking was measured by investment ratio, the amount the participant decided to bet divided by his current total assets. According to Langer's definition [J Perso Soc Psychol 32 (1975) 311-328], the illusion of control was measured by the level of personal success. The results show that the knowledge of another's gain increased risk-taking and the expectancy of personal success. These results validated the causal-model wherein the effect of the knowledge of another's gain on risk-taking was mediated by the expectancy of personal success. The discussion relates mainly to the need for taking into account the fact that gamblers are not isolated decision-makers, but takes account of some social parameters which guide their choices and actions.     

儿童基本心理需要满足对上网行为和上网情感的影响：一项追踪研究

在自我决定理论的框架下,对467名3~5年级小学生进行为期12个月的追踪调查,以探讨儿童基本心理需要满足对其上网行为和上网情感发展的影响。结果发现：（1）3~5年级儿童的上网时间、上网积极情感和上网消极情感在一年间存在着显著减少的发展趋势;（2）基本心理需要满足能够预测上网积极情感的增加和上网消极情感的减少,对上网时间发展的预测不显著;（3）自主、胜任和关系这三个维度对儿童上网情感的发展都起着重要作用。     

3～5岁幼儿暗示感受性与压力的关系:抑制性控制的调节效应

本研究在已有研究的基础上进一步探讨认知因素与外源性因素对儿童暗示感受性的交互作用。文章通过在访谈过程中设置不同水平的压力反馈,选用自编的儿童视觉暗示感受性测试材料及一系列抑制性控制实验任务,考查了儿童抑制性控制对压力和暗示感受性关系的调节作用。结果表明:(1)3～5岁幼儿的暗示感受性随着年龄的增长显著降低。(2)压力影响3～5岁幼儿的暗示感受性水平,压力越大,儿童的暗示感受性越强。(3)抑制性控制对压力与暗示感受性的关系具有显著的调节作用,压力对暗示感受性的影响会随着幼儿抑制性控制水平的提高而不断减弱。对于抑制性控制水平低的儿童来说,压力能正向预测其暗示感受性;但对于抑制性控制水平高的儿童来说,压力并不能显著预测其暗示感受性。     

Individual Differences in Leadership Emergence: Integrating Meta‐Analytic Findings and Behavioral Genetics Estimates

This paper investigates the extent to which differences in the likelihood of emerging as leaders are explained by genetic differences between individuals. Results indicated that approximately 17% of the variance in the latent construct of leadership emergence is explained by genetic effects that are mediated by intelligence and the Big Five personality traits. Because intelligence and the Big Five do not mediate all genetic influences on leadership emergence (other genetically‐influenced personal characteristics, such as height and attractiveness, are likely to mediate genetic effects on leadership emergence), the heritability estimate obtained in this study represents a lower‐bound estimate of the genetic influences on leadership emergence.     

Commuting stress process and self‐regulation at work: Moderating roles of daily task significance,family interference with work,and commuting means efficacy

Based on self‐regulation theories of stress processes, this study proposed a model to examine the within‐person mediation relationship between morning commuting stressors and self‐regulation at work via morning commuting strain. In addition, the study examined the moderating roles of daily task significance, daily family interference with work, and commuting means efficacy in this mediation model. Results from 45 bus commuters’ daily diary data over a period of 15 workdays indicated that the amount of morning commuting stressors experienced by the bus commuters was positively related to their morning commuting strain, which, in turn, had a negative impact on self‐regulation at work. At the within‐person level, daily task significance buffered the negative indirect relationship between morning commuting stressors and self‐regulation at work via morning commuting strain, whereas daily family interference with work in the morning exacerbated this negative indirect relationship. Further, at the between‐person level, commuting means efficacy buffered this negative indirect relationship such that the negative indirect effect was weaker for workers with higher (vs. lower) commuting means efficacy. Theoretical and practical implications of these findings are discussed.
