Positive vs. negative affective states are associated with the use of broad vs. specific knowledge structures. These findings were applied to the field of performance expectancies. It was predicted that individuals with positive mood should infer their performance expectancies concerning a specific task from their general self-concept, whereas given negative mood, performance expectancies should be inferred from the relevant specific self-concept. In an experiment, positive vs. negative mood was induced in 158 university students. General and specific self-concepts were assessed. Furthermore, we assessed task-specific performance expectancies and task performance. Specific self-concept was predictive of expectancies given negative mood, whereas with positive mood, expectancies could only be predicted on the basis of the general self-concept. Furthermore, mean expectancies were higher and less accurate with positive mood. The results are in line with the theoretical predictions. They underline that affective states also influence the formation of motivational variables like performance expectancies.  相似文献

Many research fields concerned with the processing of information contained in human faces would benefit from face stimulus sets in which specific facial characteristics are systematically varied while other important picture characteristics are kept constant. Specifically, a face database in which displayed expressions, gaze direction, and head orientation are parametrically varied in a complete factorial design would be highly useful in many research domains. Furthermore, these stimuli should be standardised in several important, technical aspects. The present article presents the freely available Radboud Faces Database offering such a stimulus set, containing both Caucasian adult and children images. This face database is described both procedurally and in terms of content, and a validation study concerning its most important characteristics is presented. In the validation study, all frontal images were rated with respect to the shown facial expression, intensity of expression, clarity of expression, genuineness of expression, attractiveness, and valence. The results show very high recognition of the intended facial expressions.  相似文献

We tested direct, indirect, and behavioural measures of fear of spiders under neutral instructions, and when participants were asked to fake high and low fear of spiders. Our findings indicate that the Approach Avoidance Task (AAT) was the only measure that could be faked in one of the faking conditions only. We also assessed how easily faked results could be detected on each measure for different diagnostic criteria. The direct and behavioural measures showed good performance for all criteria. The AAT performed comparably only for a conservative criterion, when detecting fakers is less important than correctly labelling non-fakers.  相似文献

Plotinus calls the first principle the One and the Good. According to Plotinus, ‘Good’ is an appropriate name for the One because the One is that which all things desire. Since he says that the One is beyond knowledge, beyond language, beyond intellect, and beyond being, however, what philosophical evidence can he provide for his claim that the One is that which all desire? In this article I offer some philosophical evidence, aside from mystical union with the One, for why ‘the Good’ is an appropriate name for the One, and for why calling the One ‘Good’ is not at odds with the fact that it is beyond knowledge, but rather entails it. To this end, after an initial consideration of the relationship between the good and desire in Plato and Aristotle, I focus on the role that desire plays in relation to the Good in Plotinus' thought.  相似文献

A study with 114 young adults investigated the correlations of intelligence factors and working-memory capacity with reaction time (RT) tasks. Within two sets of four-choice RT tasks, stimulus–response compatibility was varied over three levels: compatible, incompatible, and arbitrary mappings. Two satisfactory measurement models for the RTs could be established: A general factor model without constraints on the loadings and a nested model with two correlated factors, distinguishing compatible from arbitrary mappings, with constraints on the loadings. Structural models additionally including factors for working memory and intelligence showed that the nested model with correlated factors is superior in fit. Working-memory capacity and fluid intelligence were correlated strongly with the nested factor for the RT tasks with arbitrary mappings, and less with the general RT factor. The results support the hypothesis that working memory is needed to maintain arbitrary bindings between stimulus representations and response representations, and this could explain the correlation of working-memory capacity with speed in choice RT tasks.  相似文献

Although the intergenerational transmission of trauma has been well documented, the pathways by which trauma symptoms are passed between parents and children remain unclear. This study examined the mediating role of parenting styles in the transmission of maternal trauma to children. Participants were a sample of 105 mothers of toddlers (18–30 months old). Mothers who had experienced interpersonal trauma were more likely to have an authoritarian parenting style, including verbal hostility, physical coercion, and low nurturance. Verbal hostility especially predicted more prevalent and increasing toddler symptoms associated with affective, hyperactive, and oppositional defiant disorders. Thus, the verbal hostility component of authoritarian parenting could serve as a major intergenerational pathway between maternal trauma and early child symptoms.  相似文献

A land use many‐objective optimization problem for a 1500‐ha farm with 315 paddocks was formulated with 14 objectives (maximizing sawlog production, pulpwood production, milksolids, beef, sheep meat, wool, carbon sequestration, water production, income and Earnings Before Interest and Tax; and minimizing costs, nitrate leaching, phosphorus loss and sedimentation). This was solved using a modified Reference‐point‐based Non‐dominated Sorting Genetic Algorithm II augmented by simulated epigenetic operations. The search space had complex variable interactions and was based on economic data and several interoperating simulation models. The solution was an approximation of a Hyperspace Pareto Frontier (HPF), where each non‐dominated trade‐off point represented a set of land‐use management actions taken within a 10‐year period and their related management options, spanning a planning period of 50 years. A trade‐off analysis was achieved using Hyper‐Radial Visualization (HRV) by collapsing the HPF into a 2‐D visualization capability through an interactive virtual reality (VR)‐based method, thereby facilitating intuitive selection of a sound compromise solution dictated by the decision makers' preferences under uncertainty conditions. Four scenarios of the HRV were considered emphasizing economic, sedimentation and nitrate leaching aspects—giving rise to a triple bottomline (i.e. the economic, environmental and social complex, where the social aspect is represented by the preferences of the various stakeholders). Highlights of the proposed approach are the development of an innovative epigenetics‐based multi‐objective optimizer, uncertainty incorporation in the search space data and decision making on a multi‐dimensional space through a VR‐simulation‐based visual steering process controlled at its core by a multi‐criterion decision making‐based process. This approach has widespread applicability to many other ‘wicked’ societal problem‐solving tasks. Copyright © 2014 John Wiley & Sons, Ltd.  相似文献

Numerous studies have shown how closely nation-building accompanies research into human prehistory. While these studies primarily focus on the period before 1945, the example of the Spanish site Atapuerca demonstrates that the strong link between hominid fossils and national identity still exists in the twenty-first century. The article argues that there are different ways of appropriating prehistoric human remains. One may distinguish the concept of ‘biological continuity’ in which the fossils represent some kind of ancestor from the concept of ‘scientific nationalism’. The latter consists in the pride in the scholarly achievement and international recognition of ‘our own’ scientists. The Atapuerca project was crucial in overcoming the Spanish ‘inferiority complex’ with respect to scientific prowess. In Atapuerca we may even discern a third concept: the marketing of origins in order to lure tourists to the site – nationalism enterprised-up. The Spanish researchers created a multifold ‘popularization industry’ and forged a close alliance with the national media. Thus, this article will try to explain how Atapuerca turned within less than ten years from a little known archaeological site to the – however imaginary – starting point of Spanish history at the turn of the millennium.  相似文献

Picture‐story exercise (PSE) measures of implicit motives provide objective, stable, and valid scores. However, PSE scores are also characterized by substantial variability from one picture to the next, resulting in low internal consistency estimates. We argue that this variability is a critical source of the PSE's validity because it reveals stable if‐then contingencies between the situational contexts represented by the picture cues and individuals' motivational responses to them. We also present the correspondence hypothesis, according to which the situational cues in the PSE are representative of specific real‐life situations and a person's imaginative‐story responses to the PSE cues therefore also reflect his or her real‐life responses to such situations. We review corroborating research and discuss the implications of the if‐then contingency approach for assessment, prediction, and for the measurement of motivational congruence.  相似文献
