To test hypotheses about the universality of personality traits, college students in 50 cultures identified an adult or college-aged man or woman whom they knew well and rated the 11,985 targets using the 3rd-person version of the Revised NEO Personality Inventory. Factor analyses within cultures showed that the normative American self-report structure was clearly replicated in most cultures and was recognizable in all. Sex differences replicated earlier self-report results, with the most pronounced differences in Western cultures. Cross-sectional age differences for 3 factors followed the pattern identified in self-reports, with moderate rates of change during college age and slower changes after age 40. With a few exceptions, these data support the hypothesis that features of personality traits are common to all human groups. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

A comparison of personality traits and other characteristics of leaders and non-leaders in two southern colleges for women, Agnes Scott for white and Spelman for Negro students, is made. The materials used are the Good-enough Speed-of-Association Test, the Bernreuter Personality Inventory, and other collateral information. Small, but statistically significant, differences exist between leaders and non-leaders within a college. These differences are "definitely and reliably greater than are the differences between the two races." (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

为更深入地揭示情绪特质对建筑工人危险感知行为的影响规律,减少事故发生,立足中国建筑工人的群体与个体特质,以情绪等相关理论为支撑,基于自主开发的“情绪特质-危险感知”问卷,利用科学统计方法与指标,探究了不同情绪特质下工人的危险感知行为差异。结果表明:工人的危险感知能力与情绪特质呈正相关,良好的情绪管理能力有利于增强工人危险感知能力;情绪特质最直接影响工人危险知觉水平,情绪化的工人危险知觉水平偏弱;工人良好的情绪管理能力对危险认知有显著影响,最显著体现为提高工人信息分析稳定性。 相似文献

Empirical evidence suggests that computer self-efficacy plays an important role in one’s acceptance and use of new information technology. Little is however known about the antecedents of computer self-efficacy. This paper reports on a study of 143 non-users of a self-checkout library system available at a large Canadian university which was conducted to investigate the relationships between stable personality traits and gender with computer self-efficacy. Results indicate that four of the five stable personality traits, as measured by the Big-5 factors of personality, contribute to explain computer self-efficacy. Taking gender into account, results show that the traits of neuroticism, extraversion, and agreeableness are significantly related to computer self-efficacy for women but not for men. Implications for research and practice are discussed. 相似文献

The authors tested hypotheses concerning personality differences in treatment-seeking suicide attempters (AT; n = 60) and a community sample of suicides (SU; n = 43) over age 50. On the basis of prior research, the authors hypothesized that SU would be lower in Neuroticism and Openness and higher in Conscientiousness. A 2-group (AT vs. SU) multivariate analysis of covariance with NEO Personality Inventory--Revised (Informant Version) domain scores as dependent variables revealed that SU were lower in Neuroticism and higher in Conscientiousness. The authors conclude that AT and SU in this age group can be distinguished on the basis of informant ratings of personality traits. These differences can inform risk detection.

A reciprocal impact hypothesis posits an influence of gender-related traits (agency and communion) on role enactment and a reciprocal impact of role enactment on gender-related traits, for both men and women. Specifically, in this study it was predicted that agency influences career success and career success influences agency. In addition, the reciprocal influence of communion and family roles was examined. A prospective study with almost 2,000 university graduates, who were tested after graduation and 1.5 years later, clearly supported the reciprocal impact hypothesis for agency and career success. Communion influenced family roles, but there was no reciprocal influence. Implications for theories of career success and of sex and gender are discussed.

Adaptive evolution of dispersal strategies is one mechanism by which species can respond to rapid environmental changes. However, under rapid anthropogenic fragmentation, the evolution of dispersal may be limited, and species may be unable to adequately adapt to fragmented landscapes. Here, we develop a spatially explicit model to investigate the evolution of dispersal kernels under various combinations of fragmentation dynamics and initial conditions. We also study the consequences of modelling an evolutionary process in which dispersal phenotypes continuously and gradually shift in phenotype space in a manner corresponding to a polygenic underlying genetic architecture. With rapid fragmentation rates, we observed the emergence of long-term transient states in which dispersal strategies are not well suited to fragmented landscapes. We also show that the extent and length of these transient states depend on the pre-fragmentation dispersal strategy of the species, as well as on the rate of the fragmentation process leading to the fragmented landscape. In an increasingly fragmented world, understanding the ability of populations to adapt, and the effects that rapid fragmentation has on the evolution of dispersal, is critical for an informed assessment of species viability in the Anthropocene. 相似文献

Panicle traits are important factors affecting yield, and their improvement has long been a critical goal in foxtail millet breeding. In order to understand the genetic basis of panicle formation, a large-scale genome-wide association study (GWAS) was performed in this study for six panicle-related traits based on 706,646 high-polymorphism SNP loci in 407 accessions. As a result, 87 quantitative trait loci (QTL) regions with a physical distance of less than 100 kb were detected to be associated with these traits in three environments. Among them, 27 core regions were stably detected in at least two environments. Based on rice–foxtail millet homologous comparison, expression, and haplotype analysis, 27 high-confidence candidate genes in the QTL regions, such as Si3g11200 (OsDER1), Si1g27910 (OsMADS6), Si7g27560 (GS5), etc., affected panicle-related traits by involving multiple plant growth regulator pathways, a photoperiod response, as well as panicle and grain development. Most of these genes showed multiple effects on different panicle-related traits, such as Si3g11200 affecting all six traits. In summary, this study clarified a strategy based on the integration of GWAS, a homologous comparison, and haplotype analysis to discover the genomic regions and candidate genes for important traits in foxtail millet. The detected QTL regions and candidate genes could be further used for gene clone and marker-assisted selection in foxtail millet breeding. 相似文献
