This study examines the effects of physical attractiveness and aggression on popularity among high school students. Previous
work has found positive relationships between aggression and popularity and physical attractiveness and popularity. The current
study goes beyond this work by examining the interactive effects of physical attractiveness and aggression on popularity.
Controlling for race and gender, the results indicate that attractive students are seen as more physically and relationally
aggressive than those who are less attractive. We also found that those who are both physically attractive and aggressive
are perceived to be more popular than those without such characteristics. However, the same interaction showed the opposite
effect when predicting sociometric popularity instead of perceived popularity. These results contribute to the understanding
of the differences between those who are well-liked (sociometric popularity) and those who are socially visible (perceived
popularity), and the unique predictors of these two dimensions of status in the peer group. 相似文献

Ellis and Beaton (1993a) reported that the keyword method of learning enhanced memory of foreign vocabulary items when receptive learning was measured. However, for productive learning, rote repetition was superior to the keyword method. The first two experiments reported here show that, in comparison with rote repetition, both receptive and productive learning can be enhanced by the keyword method, provided that the quality of the keyword images is adequate. In a third experiment using a subset of words from Ellis and Beaton (1993a), the finding they reported, that for productive learning rote repetition was superior to the keyword method, was reversed. The quality of keyword images will vary from study to study and any generalisation regarding the efficacy of the keyword method must take this into account. 相似文献

The gender similarities hypothesis 总被引:4,自引:0,他引:4
Hyde JS 《The American psychologist》2005,60(6):581-592
The differences model, which argues that males and females are vastly different psychologically, dominates the popular media. Here, the author advances a very different view, the gender similarities hypothesis, which holds that males and females are similar on most, but not all, psychological variables. Results from a review of 46 meta-analyses support the gender similarities hypothesis. Gender differences can vary substantially in magnitude at different ages and depend on the context in which measurement occurs. Overinflated claims of gender differences carry substantial costs in areas such as the workplace and relationships. 相似文献

Gender differences in temperament: a meta-analysis 总被引:1,自引:0,他引:1
The authors used meta-analytical techniques to estimate the magnitude of gender differences in mean level and variability of 35 dimensions and 3 factors of temperament in children ages 3 months to 13 years. Effortful control showed a large difference favoring girls and the dimensions within that factor (e.g., inhibitory control: d = -.41, perceptual sensitivity: d = -0.38) showed moderate gender differences favoring girls, consistent with boys' greater incidence of externalizing disorders. Surgency showed a difference favoring boys, as did some of the dimensions within that factor (e.g., activity: d = 0.33, high-intensity pleasure: d = 0.30), consistent with boys' greater involvement in active rough-and-tumble play. Negative affectivity showed negligible gender differences. 相似文献

Approximately 40-60% of BXSB mice have neocortical ectopias, a developmental anomaly characterized by migration of neurons into the neuron-sparse layer I of cortex. Previous studies have shown that ectopic BXSB mice have superior reference, but inferior working, memory on spatial tasks. Female BXSB mice were housed either in an enriched environment or in standard cages at weaning. Subsequently, these animals were tested on four of the Hebb-Williams mazes in a water-based version of this maze. Theoretically, two of the maze configurations placed greater emphasis on reference memory to find the goal, whereas the other two favored working memory. Ectopics reared in standard housing conditions were better than nonectopics on mazes that favored the use of reference memory, but poorer on mazes that favored working memory. In contrast, subjects raised in the enriched environment showed no ectopia differences. A comparison of enriched and standard housing conditions found that the enriched animals had better reference memory but poorer working memory. The latter effect may be because the enriched environment, although more stimulating, did not change in time or space; and other researchers have shown that daily replacement of stimuli in complex environments is correlated with better working memory. 相似文献

ABSTRACT— I review new trends in research on the psychology of gender. The gender similarities hypothesis holds that males and females are similar on most, but not all, psychological variables. Gender is not only an individual-difference or person variable but also a stimulus variable. Emerging approaches to cross-national measurement of constructs such as gender equality provide new insights into patterns of gender differences and similarities across cultures. Current neuroscience approaches emphasize neural plasticity and provide the opportunity to study neural correlates of males' and females' differential experiences. 相似文献

Recent research reveals a link between individual differences in mathematics achievement and performance on tasks that activate the approximate number system (ANS): a primitive cognitive system shared by diverse animal species and by humans of all ages. Here we used a brief experimental paradigm to test one causal hypothesis suggested by this relationship: activation of the ANS may enhance children’s performance of symbolic arithmetic. Over 2 experiments, children who briefly practiced tasks that engaged primitive approximate numerical quantities performed better on subsequent exact, symbolic arithmetic problems than did children given other tasks involving comparison and manipulation of non-numerical magnitudes (brightness and length). The practice effect appeared specific to mathematics, as no differences between groups were observed on a comparable sentence completion task. These results move beyond correlational research and provide evidence that the exercise of non-symbolic numerical processes can enhance children’s performance of symbolic mathematics. 相似文献
