Reactive and proactive aggression: Similarities and differences 总被引:2,自引:1,他引:2
The purpose of the current study was to elaborate the nomological net surrounding the constructs of reactive (RA) and proactive aggression (PA). Typically examined in the context of children, the current study utilized a sample of 211 young adults to examine the relations between reactive and proactive aggression and measures of general personality and social information processing, as well as maladaptive behavioral correlates such as crime, substance use, and riskier sex. Both raw and residualized scores were examined. Using raw scores, the primary differences between RA and PA were related to Neuroticism (i.e., RA more strongly related) and externalizing behaviors (i.e., PA more strongly). The authors comment on the similarity of findings when using raw scores and the divergence of findings using residualized scores and argue for a cautious interpretation of differences based on residualized scores. The authors conclude that the role of Neuroticism warrants further exploration as a means for understanding the heterogeneity of aggressive behavior. 相似文献

This article discusses 3 modern forced-choice personality tests developed for the U.S Armed Services to provide resistance to faking and other forms of response distortion: the Assessment of Individual Motivation, the Navy Computerized Adaptive Personality Scales, and the Tailored Adaptive Personality Assessment System. These tests represent the transition from Likert to forced-choice formats and from static to computerized adaptive item selection to meet the challenges of large-scale, high-stakes testing environments. For each test, we briefly describe the personality constructs that are assessed, the response format and scoring methods, and selected ongoing research and development efforts. We also highlight the potential of these tests for personnel selection, classification, and diagnostic screening purposes. 相似文献

ObjectiveTo examine the associations between personality traits, measured as Murray’s psychological needs, and mortality over 41 years.MethodWe used a general population sample aged 18–65 (n = 1094) examined in 1970 according to the Cesarec-Marke Personality Schedule (eleven traits) linked to mortality data. Internal associations were examined using factor analysis, and their associations with mortality using Cox proportional hazard regression models.ResultsDuring follow-up, 513 persons died. In men aged 26–45, achievement and affiliation predicted increased mortality: HR = 1.19, 95% CI 1.04–1.36 and HR = 1.16, 95% CI 1.01–1.33 per step on a stanine scale. In men aged 18–25, nurturance was protective: HR = 0.77, 95% CI, 0.64–0.98 per stanine. In women aged 18–25, feelings of guilt increased the risk of mortality, while dominance was protective: HR = 1.38, 95% CI 1.09–1.75, and HR = 0.74, 95% CI 0.55–0.99 per stanine, respectively. In women aged 46–65, exhibition increased the risk of mortality: HR = 1.09, 95% CI, 1.00–1.18 per stanine. There were no significant associations when all age groups were combined.ConclusionsPersonality traits, measured as Murray’s needs, associated with mortality, but the differed according to age at assessment and sex. 相似文献

本研究借鉴传统计算机化自适应测验的思想, 并结合认知诊断的特点, 在认知诊断框架下提出了4种变长CD-CAT的终止规则, 分别是属性标准误法(SEA)、邻近后验概率之差法(DAPP)、二等分法(HA)以及混合法(HM)。在未控制曝光和采用不同曝光控制条件下, 与HSU法及KL法进行了比较。研究结果表明:(1) 终止条件越严格, 平均测验长度越长, 按测验长度最大值终止的测验百分比越大, 模式判准率越高。(2) 当未加入曝光控制时, 4种新的终止规则均有较好表现, 与HSU法十分接近。随着最大后验概率预设值的增加或e的减小, 模式判准率呈上升趋势, 平均测验长度逐渐增加, 但在题库使用率方面均较差。(3) 当加入项目曝光控制时, 6种变长终止规则下的题库使用率有了极大的提升, 仍能保持较高的模式判准率, 并且不同的曝光控制方法对终止规则的影响是不同的。其中, 相对标准终止规则极易受到曝光控制方法的影响。(4) 综合来看, SEA、HM以及HA法在各项指标上的表现与HSU法基本一致, 其次为KL法和DAPP法。 相似文献

The Big Five Inventory–2 (BFI-2) uses 60 items to hierarchically assess the Big Five personality domains and 15 more-specific facet traits. The present research develops two abbreviated forms of the BFI-2—the 30-item BFI-2-S and the 15-item BFI-2-XS—and then examines their measurement properties. At the level of the Big Five domains, we find that the BFI-2-S and BFI-2-XS retain much of the full measure’s reliability and validity. At the facet level, we find that the BFI-2-S may be useful for examining facet traits in reasonably large samples, whereas the BFI-2-XS should not be used to assess facets. Finally, we discuss some key tradeoffs to consider when deciding whether to administer an abbreviated form instead of the full BFI-2. 相似文献

Minimally-invasive surgery (MIS) offers many benefits to patients, but is considerably more difficult to learn and perform than is open surgery. One main reason for the observed difficulty is attributable to the visuo-spatial challenges that arise in MIS, taxing the surgeons’ cognitive skills. In this contribution, we present a new approach that combines training and assistance as well as the visual and the auditory modality to help surgeons to overcome these challenges. To achieve this, our approach assumes two main components: An adaptive, individualized training component as well as a component that conveys spatial information through sound. The training component (a) specifically targets the visuo-spatial processes crucial for successful MIS performance and (b) trains surgeons in the use of the sound component. The second component is an auditory display based on a psychoacoustic sonification, which reduces and avoids some of the commonly experienced MIS challenges. Implementations of both components are described and their integration is discussed. Our approach and both of its components go beyond the current state of the art in important ways. The training component has been explicitly designed to target MIS-specific visuo-spatial skills and to allow for adaptive testing, promoting individualized learning. The auditory display is conveying spatial information in 3-D space. Our approach is the first that encompasses both training for improved mastery and reduction of cognitive challenges in MIS. This promises better tailoring of surgical skills and assistance to the needs and the capabilities of the surgeons and, thus, ultimately, increased patient safety and health. 相似文献

Research indicates that decision-making competence in everyday life is associated with certain decision-making styles. The aims of this article are to extend this research by examining (a) the extent to which general cognitive styles explain variance in decision-making competence over and above decision-making styles, and (b) the extent to which personality explains variance in decision-making competence over and above both types of style variable. Participants (N = 355) completed measures of everyday decision-making competence (Decision Outcomes Inventory), decision styles (Decision Style Questionnaire; Maximization Inventory), cognitive styles (the Cognitive Styles Inventory; Rational-Experience Inventory), and the Big Five personality variables (IPIP Big-Five factor scales). The results indicate that cognitive styles offer no incremental validity over decision-making styles in predicting decision-making competence, but that personality does offer substantial incremental validity over general cognitive styles and decision-making styles. Jointly decision-making styles and personality account for a substantial amount of variance in everyday decision-making competence. 相似文献
