员工建言行为的人口统计特征元分析

研究目的在于明确人口统计学特征与员工建言行为的关系。共81篇实证文献被纳入元分析, 被试人数为39118人。结果发现, 员工年龄、教育程度、组织任期和职位均与建言行为显著正相关, 即年龄越大、受教育程度越高、组织任期越长的员工会表现出越多建言行为; 同时, 在不同的文化背景下, 职位高低与建言行为的关系存在显著差异, 受中国传统文化影响, 高、低职位员工的建言行为数量差异明显, 而在非中国情境下, 员工职位高低对其建言行为的数量影响差异不明显; 此外, 建言行为的数据来源对员工年龄与建言行为之间的关系存在显著调节作用, 采用他评方式时, 年龄与建言行为的正向关系更为显著。研究结果为人口统计特征预测建言行为提供较为精确的估计, 并为未来建言行为的相关研究指引了方向。     

The role of sex hormones and of 2D:4D ratio in individual differences in cognitive abilities

The present study aimed at investigating the role of sex hormones in individual differences in cognitive abilities. This was achieved by a combination of two methods, reflecting 2 critical periods of hormonal secretion: prenatal, based on the 2D:4D ratio, and postnatal, based on circulating hormone levels. Both methods were tested in 39 men and 41 women, who completed a battery of 6 cognitive tasks. Results showed significant sex differences on the mental rotation task, with men outperforming women. A positive correlation was found between testosterone and performance on the mental rotation task for the combined sample (men and women). A significant interaction was found between sex and estrogen on mental rotation task. Findings also revealed a significant interaction between sex and right hand 2D:4D ratio on different memory tasks. Findings regarding between- and within-sex differences in cognition are discussed in light of the organisational and activational effects of sex hormones.     

Effet du genre sur la relation humain-technologie : importance du sentiment de maîtrise

This research focuses on gender differences in perceived relationship with technology in particular for professional use. It aims to show at which levels the differences between men and women are focused, using the theory of technosymbiosis to highlight gender differences’. With a questionnaire, 155 workers of half of both genders were asked about their relationship with technology through 6 cross dimensions (functionality, usability, regulations, technology, human and context). It appears that it is not the technological features that are put in default by the women but their feeling to control these technologies.

An empirical examination of sex differences in scoring preschool children's aggression

Sex differences in adults’ observations and ratings of children’s aggression was studied in a sample of preschool children (N = 89, mean age = 44.00 months, SD = 8.48). When examining the direct observations made by trained observers, male observers, relative to female observers, more frequently recorded aggressive bouts, especially of boys. On rating scales assessing aggression, trained male raters also gave higher aggressive ratings than female raters. Lastly, we compared the ratings of trained female raters and female teachers on the same scale and found no differences. Results are discussed in terms male raters’ and observers’ prior experiences in activating their experiential schemata where males’ greater experience in aggression, relative to that of females, leads them to perceive greater levels of aggression.     

Information integration study of Metelli's and Morinaga's theories of achromatic transparency

Information integration methodology was used to test Metelli's and Morinaga's theories of achromatic transparency. Stimuli were transparent achromatic disks on a background formed by two adjacent horizontal rectangles. The common border of these rectangles divided each disk in two halves. Let P and Q be the luminances of the left and right halves of a disk and let A and B be those of the left and right rectangles, respectively. Transparency is given by the ratio (P – Q)/(A – B) in Metelli's theory and is given by a weighted average of the ratios (P – Q)/(A – Q) and (P – Q)/(P – B) in Morinaga's theory. Participants rated the transparency of disks with A and B fixed and P and Q combined factorially. Morinaga's theory closely predicted the resulting pattern of curves and Metelli's theory predicted it incorrectly. Morinaga's theory could also account well for individual differences in the ratings of transparency. The results support the general idea that transparency depends on the integration of photometric luminance information rather than on the integration of perceived lightness information.     

Stability of peer victimization in early adolescence: effects of timing and duration

The current study investigated the stability of peer victimization and the impact of the timing and duration of victimization on psychological and academic outcomes for boys and girls on a sample of 863 middle school students. Results demonstrated strong support for the onset hypothesis and concurrent effects of maladjustment in anxiety, depression, self-esteem, poor school attitude, GPA, and attendance. Support for the cessation hypothesis was mixed, depending on the outcome and gender: boys demonstrated recovery from internalizing distress, whereas girls demonstrated residual effects, even after the cessation of victimization. Girls also demonstrated residual effects of victimization on grades, and both boys and girls evidenced residual effects of victimization on attendance. Regarding duration of victimization, there was strong support for the life-events model of stress and coping across almost all outcomes, suggesting that even temporary experiences of victimization could have a negative impact on psychological and academic outcomes. Overall, results demonstrated the importance of considering the timing and duration of victimization in understanding the risks and damaging effects of victimization. The results from this study also highlight both the need and the potential to intervene during early adolescence when peer relationships are taking on increasing importance, as well as the importance of helping students regain social-emotional and academic functioning, even after victimization ceases.     

Social comparisons in the classroom: an investigation of the better than average effect among secondary school children

The better than average (BTA) effect refers to the tendency for the majority of people to rate themselves as being higher on positive attributes and lower on negative attributes than other people. The present study examined the occurrence of the BTA effect on five important characteristics among 15,806 first-year secondary school Dutch students. In addition, it explored the influence of students' gender, cultural background, and ability level on their evaluations of characteristics relative to their classmates. Results yielded small BTA effects, with the exception of the item “being eager to get high grades,” on which the effect was much larger. In addition, larger BTA effects were found among boys than girls, but this difference could not be attributed to actual differences in performance. Likewise, larger BTA effects were found among ethnic minority students from Turkish and Moroccan backgrounds than ethnic majority students, but this difference also could not be attributed to actual differences in performance. Theoretical and practical implications of these findings are discussed.     

Target-mask shape congruence impacts the type of metacontrast masking

Visual metacontrast masking may depend on the time intervals between target and mask in two qualitatively different ways: in type-A masking the smaller the mask delay from target the stronger the masking while in type-B masking maximal masking effect is obtained with a larger temporal delay of the mask. Variability in the qualitative apperance of masking functions has been explained by variability in stimuli parameters and tasks. Recent research on metacontrast masking has surprisingly shown that both of these types of functions can be found with an identical range of stimulation parameters depending on individual differences between observers. Here we show that obtaining clear-cut type-A masking depends on whether target and mask shapes are congruent or incongruent and whether observers use the cues available due to the congruence factor. Conspicuously expressed type-A masking is selectively associated with incongruent target-mask pairings. In the latter conditions target identification level significantly drops with the shortest target-to-mask delays.     

Personality and gang embeddedness

Gang membership can be transient or persistent, and most persons who participate in such groups at one point in their lives grow out of the lifestyle. The personality dynamics driving gang membership are poorly understood, although the five-factor model of personality has proved an effective way to understanding many types of antisocial behaviour. Using dichotomous self-nomination 152 remand and sentenced participants incarcerated within a general prison in London, UK indicated their gang embeddedness as youths, prior to custody, within prison, and as an intent following release. This enabled behavioural intention to be incorporated into the model as well as historical factors. Constructs derived from a variety of personality measures and constructs were used to predict overall reported gang embeddedness. These predictors reduced to two underlying dimensions: personal resilience and antisocial personality. Path analysis showed the antisocial personality dimension predicted previous convictions and degree of gang embeddedness, whereas resilience did not. The direct and indirect effects of the composite antisocial personality dimension explained 50% of the overall observed variance in gang embeddedness. We suggest that gang membership may reflect normal assortative processes within the members of such groups.
