Work–home interference (WHI) is a prevalent problem because most employees have substantial family responsibilities on top of their work demands. The present study hypothesized that high job demands in combination with low job resources contribute to WHI. The job demands–resources (JD-R) model was used as a theoretical framework. Using a sample of 230 medical residents and their partners, our results show that the combination of high job demands (i.e., work overload, emotional and cognitive demands) and low job resources (i.e., participation in decision making, supervisory coaching, feedback, and opportunities for development) was positively related to partner ratings of the employee's WHI. When job resources were high, most job demands were not related to WHI. These findings show that the JD-R model is a conceptual framework that can be fruitfully applied to the work–family interface, adding to our understanding of which particular job designs facilitate or prevent work–home interference. 相似文献

With only two to five slots of visual working memory (VWM), humans are able to quickly solve complex visual problems to near optimal solutions. To explain the paradox between tightly constrained VWM and impressively complex human visual problem-solving ability, we propose several principles for dynamic VWM allocation. In particular, we propose that complex visual information is represented in a temporal manner using only a few slots of VWM that include global and local visual chunks. We built a model of human traveling salesman problem solving based on these principles of VWM allocation and tested the model with eye-movement data. Exactly as the model predicted, human eye movements during traveling salesman problem solving have precise quantitative regularities with regard to both the general statistical pattern of attentional fixations and how they vary across individuals with different VWM capacities. Even though VWM capacity is very limited, eye movements dynamically allocate VWM resources to both local and global information, enabling attention to fine details without loss of the big picture. 相似文献

闪光滞后效应(flash-lag effect)是指在与运动物体一致的位置上呈现闪光(flash),知觉上闪光落后于运动物体的视错觉。延迟差异理论认为,产生该现象的原因是视觉系统加工闪光的速度比加工运动物体慢。根据该理论,作者预测:如采用知觉加工速度更快(或更慢)的客体替代闪光,应能相应地产生更小(或更大)的闪光滞后效应。为了检验该预测,作者以"客体突现"(onset)和"客体消失"(offset)替代闪光滞后实验中的闪光,结果发现,"突现"的知觉滞后大于"消失",但时序判断任务表明"突现"的知觉延迟比"消失"短。该结果并不支持延迟差异理论。 相似文献

New Volitionalism is a name for certain widespread conception of the nature of intentional action. Some of the standard arguments
for New Volitionalism, the so-called arguments from total failure, have even acquired the status of basic assumptions for
many other kinds of philosophers. It is therefore of singular interest to investigate some of the most important arguments
from total failure. This is what I propose to do in this paper. My aim is not be to demonstrate that these arguments are inconsistent
or that total failure and naked tryings are metaphysically impossible. Rather, my aim is be to build a case against the possibility
of naked, independently existing tryings, by questioning how well we understand the scenarios invoked in their favour. Thus,
rather than attempting to present a definitive metaphysical refutation of New Volitionalism, I attempt to diminish or demolish
its underlying motivation.

This report documents relationships between differential item functioning (DIF) identification and: (1) item–trait association, and (2) scale multidimensionality in personality assessment. Applying [Zumbo, B. D. (1999). A handbook on the theory and methods of differential item functioning (DIF): Logistic regression modeling as a unitary framework for binary and Likert-type (ordinal) item scores. Ottawa, ON: Directorate of Human Resources Research and Evaluation, Department of National Defense.] logistic regression model, DIF effect size is found to become increasingly inflated as investigated item associations with trait scores decrease. Similar patterns were noted for the influence of scale multidimensionality on DIF identification. Individuals who investigate DIF in personality assessment applications are provided with estimates regarding the impact of the magnitude of item and trait association and scale multidimensionality on DIF occurrence and effect size. The results emphasize the importance of excluding investigated items in focal trait identification prior to conducting DIF analyses and reporting item and scale psychometric properties in DIF reports. 相似文献

Research on the structure of personality in middle childhood, while advancing, is still in the early stages of development. In this study, we employed a group of 1563 twins to elucidate the hierarchical structure of personality in middle childhood and provide connections to established personality traits in adult populations. Our results provide evidence for a higher-order structure of personality in middle childhood that maps on to recent findings in adult populations supporting hierarchical relationships among 2-, 3-, 4-, and 5-factor models of personality. In addition, primary higher-order personality traits rated by parents at age 11 showed substantial predictive validity for analogous traits rated by self at age 17. We discuss our results within the context of developing a convergent hierarchical taxonomy of personality in middle childhood and the importance of multi-informant investigations. 相似文献

To better understand the greater prevalence of depression among women, compared to men, we explored the darker side of accommodating others by examining where maladaptive relational constructs fit within a general structural framework provided by the interpersonal circumplex and 5-factor model of personality. Participants were four samples of undergraduate students (Ns = 302–2070) who completed questionnaires. Results indicated two clusters of maladaptive items: Submission with Connection and Submission without Connection. In general, the most maladaptive relational constructs were concentrated in the first cluster and were located in the low agency, low communion region of the interpersonal circumplex. 相似文献

Procedural norms are instrumental norms addressed to agents playing a role in the normative system, for example to motivate these role playing agents to recognize violations or to apply sanctions. Procedural norms have first been discussed in law, where they address legal practitioners such as legislators, lawyers and policemen, but they are discussed now too in normative multiagent systems to motivate software agents. Procedural norms aim to achieve the social order specified using regulative norms like obligations and permissions, and constitutive norms like counts-as obligations. In this paper we formalize procedural, regulative and constitutive norms using input/output logic enriched with an agent ontology and an abstraction hierarchy. We show how our formalization explains Castelfranchi's notion of mutual empowerment, stating that not only the agents playing a role in a normative system are empowered by the normative system, but the normative system itself is also empowered by the agents playing a role in it. In our terminology, the agents are not only institutionally empowered, but they are also delegated normative goals from the system. Together, institutional empowerment and normative goal delegation constitute a mechanism which we call delegation of power, where agents acting on behalf of the normative system become in charge of recognizing which institutional facts follow from brute facts. 相似文献

态度是社会心理学研究的重要领域,近年来研究者发现通过说服可以改变个体的态度,所以态度的说服策略成为一个研究的重点。说服包括了陈述论据和事实,推理,做结论和说明所推荐行为方式的积极效果,所有的一切都是为了使受众相信并且按照这种行为方式行事。本文沿着历史的脉络,从不同的角度阐述了各种说服策略的理论解释及其实验研究,并在此基础上叙述了说服策略未来研究趋势。 相似文献
