追求幸福是人类社会永恒的主题。价值观对个体的发展起引导作用,与幸福感密切相关。认同自我增强价值观,即关注个人利益,可以让人体验到波动的幸福感,表现为短暂快乐和消极情绪的交替循环;认同自我超越价值观,即切实关心他人利益和福祉,则可以让人拥有持久的幸福感,表现为一种持续的充实、和谐、宁静的状态。就作用机制而言,认同自我超越价值观的个体可能对自我威胁信息有较少的防御性反应,体验到更多的社会关系导向的情绪,激发更多的亲社会行为,从而获得持久的幸福体验。未来的研究可采用多种方法和手段考察自我超越价值观对持久幸福感的作用,系统探讨二者之间的其他潜在机制,并通过开展自我超越价值观教育形成良好的社会心态。 相似文献

When spatial ability was regressed on a measure of general intelligence in a large national sample of 12th-graders, there was a distinct downturn in the regression line at about -2 SD units. A bimodal distribution of spatial ability was found among these low scoring students, suggesting 2 qualitatively different types of individuals. Relative to students of expected spatial ability, those below expected in spatial ability were high on verbal skills and low on performance skills. Students unexpectedly low in spatial ability performed relatively well on cognitive tests that required answering unambiguous questions by retrieving information directly from long term memory, whereas they performed relatively poorly on tests requiring inference and perception of relations among novel stimuli. Students unexpectedly low in spatial ability performed especially poorly at tests involving visual-spatial perception skills. Results were similar for both sexes. The relatively poor performance of those unexpectedly low in spatial ability does not appear to be related to health problems, personality, interest differences, or biographical data. An organic impairment possibly related to lateralization represents a reasonable causal hypothesis for these data. 相似文献

The relationship between counting knowledge and computational skills (i.e., skill at counting to solve addition problems) was assessed for groups of first-grade normal and mathematically disabled (MD) children. Twenty-four normal and 13 MD children were administered a series of counting tasks and solved 40 computer-administered addition problems. For the addition task, problem-solving strategies were recorded on a trial-by-trial basis. Performance on the counting tasks suggested that the MD children were developmentally delayed in the understanding of essential and unessential features of counting and were relatively unskilled in the detection of certain forms of counting error. On the addition task, the MD children committed many more computational errors and tended to use developmentally immature counting procedures. The immature counting knowledge of the MD children, combined with their relatively poor skills at detecting counting errors, appeared to underlie their poor computational skills on the addition task. Suggestions for future research are presented. 相似文献

There is a dearth of knowledge about factors correlated with suicide risk among minority groups in Western societies. In the present study we compared suicide risk among persons with foreign background with that of the majority population to determine whether certain minority groups are at a particular risk for suicide, as well as to illuminate gender differences herein. Suicide risk was generally higher among persons with foreign background compared with the majority population and the risk was highest among Nordic-born persons. Overall, suicide risk was significantly lower among Asian-born persons; however, there were gender differences in correlations between ethnicity and suicide risk. 相似文献

Mere ownership effect is the phenomenon that people tend to value what they own more than what they do not own. This classic effect is considered robust, yet effect sizes vary across studies, and the effect is often confused for or confounded with other classic phenomena, such as endowment or mere exposure effects. We conducted a pre-registered meta-analysis of 26 samples published before 2019 (N = 3024), which resulted in psychological ownership on valuing effect of g ∼ 0.57 [0.46, 0.69]. Suggestive moderator analyses supported the use of replica as the strongest moderators. Mere ownership effects were different from the null across all moderator categories and in most publication bias adjustments. We consider this as suggestive evidence that psychological owning leads to valuing, yet caution that much more research is needed.

We developed an adaptive forced-choice method whereby reference and test presentations were alternated in order to minimize effects from variables such as subject attention level. In our demonstration example of an X-ray fluoroscopy perception study, we measured detectability of low-contrast objects in noisy image sequences and determined X-ray dose levels for equivalent detectability of identical contrasts for a new test acquisition method (fluoroscopy at 15 acq/sec) as compared with a reference (conventional fluoroscopy at 30 acq/sec). In preliminary experiments, we found a dose savings with the test method. We derived parameter uncertainties for the adaptive procedure and demonstrated their applicability with Monte Carlo simulations. Repeated experiments on a single subject demonstrated reduced standard errors due to the reduction of day-to-day variations. It is believed that the method can be applied in a variety of situations in which one needs to compare perception measurements. 相似文献
