In the ordinary way of representing relations, the order of the relata plays a structural role, but in the states themselves such an order often does not seem to be intrinsically present. An alternative way to represent relations makes use of positions for the arguments. This is no problem for the love relation, but for relations like the adjacency relation and cyclic relations, different assignments of objects to the positions can give exactly the same states. This is a puzzling situation. The question is what is the internal structure of relations? Is the use of positions still justified, and if so, what is their ontological status? In this paper mathematical models for relations are developed that provide more insight into the structure of relations “out there” in the real world. 相似文献

In transitive inference, participants learn a set of context-dependent discriminations that can be organized into a hierarchy that supports inference. Several studies show that inference occurs with or without task awareness. However, some studies assert that without awareness, performance is attributable to pseudoinference. By this account, inference-like performance is achieved by differential stimulus weighting according to the stimuli's proximity to the end items of the hierarchy. We implement an inference task that cannot be based on differential stimulus weighting. The design itself rules out pseudoinference strategies. Success on the task without evidence of deliberative strategies would therefore suggest that true inference can be achieved implicitly. We found that accurate performance on the inference task was not dependent on explicit awareness. The finding is consistent with a growing body of evidence that indicates that forms of learning and memory supporting inference and flexibility do not necessarily depend on task awareness. 相似文献

This study examined whether children exposed to prenatal smoking show deficits in “hot” and/or “cool” executive functioning
(EF). Hot EF is involved in regulation of affect and motivation, whereas cool EF is involved in handling abstract, decontextualized
problems. Forty 7 to 9-year-old children (15 exposed to prenatal smoking, 25 non-exposed) performed two computerized tasks.
The Sustained Attention Dots (SA-Dots) Task (as a measure of “cool” inhibitory control) requires 400 non-dominant hand and
200 dominant hand responses. Inhibitory control of the prepotent response is required for dominant hand responses. The Delay
Frustration Task (DeFT) (as a measure of “hot” inhibitory control) consists of 55 simple maths exercises. On a number of trials
delays are introduced before the next question appears on the screen. The extent of response-button pressing during delays
indicates frustration-induced inhibitory control. Prenatally exposed children showed poorer inhibitory control in the DeFT
than non-exposed children. A dose–response relationship was also observed. In addition, prenatally exposed children had significantly
higher (dose-dependent) conduct problem- and hyperactivity-inattention scores. There were no significant group differences
in inhibitory control scores from the SA-Dots. These results indicate that children exposed to prenatal smoking are at higher
risk of hot but not cool executive function deficits. 相似文献

Older cities struggling with issues of survival focus on jobs and the economy, but competition requires all cities to pay
attention to the quality of life that attracts residents. Creating such an inviting environment includes “third places” that
foster community and communication among people outside of home and work, yet we have little empirical evidence that speaks
to the subject, or their importance for a community’s quality of life. Here we report on a national U.S. survey that asked
people to identify such places in their community, producing a wide variety of “third places” that ranged from the most popular
community centers, coffee shops and restaurants to parks and malls. While a few relationships are found between population/diversity
and the popularity of particular third places, the most important result confirms a hypothesized relationship between perceptions
that third places are accessible in their community and the perceived quality of life. 相似文献

Rough‐and‐tumble play (RTP) is a common form of play between fathers and children. It has been suggested that RTP can contribute to the development of selfregulation. This study addressed the hypothesis that the frequency of father–child RTP is related to the frequency of physically aggressive behavior in early childhood. This relationship was expected to be moderated by the dominance relationship between father and son during play. Eighty‐five children between the ages of 2 and 6 years were videotaped during a free‐play session with their fathers in their homes and questionnaire data was collected about father–child RTP frequency during the past year. The play dyads were rated for the degree to which the father dominated play interactions. A significant statistical interaction revealed that RTP frequency was associated with higher levels of physical aggression in children whose fathers were less dominant. These results indicate that RTP is indeed related to physical aggression, though this relationship is moderated by the degree to which the father is a dominant playmate. Aggr.

An empirically corroborated model of proenvironmental commitments is outlined. According to this model, willingness to contribute to the saving of global commons (atmosphere, oceans, etc.) is motivated by the awareness of global ecological risks, by perceived injustices of the distributions of benefits and costs resulting from exploiting and polluting activities, and by the conviction that many actors—ordinary citizens as well as powerful authorities in business and politics—have both effective means and responsibilities to contribute to the protection of the environment. Political implications are drawn from the typical attributional pattern of multi‐responsibility for environmental protection and from the perception of distributive injustices of the current overuse and pollution of commons. Basic issues of ecological justice are discussed. 相似文献

This conceptual paper examines the promises and critical challenges posed by contemporary personality measurement using big data. More specifically, the paper provides (i) an introduction to the type of technologies that give rise to big data, (ii) an overview of how big data is used in personality research and how it might be used in the future, (iii) a framework for approaching big data in personality science, (iv) an exploration of ideas that connect psychometric reliability and validity, as well as principles of fairness and privacy, to measures of personality that use big data, (v) a discussion emphasizing the importance of collaboration with other disciplines for personality psychologists seeking to adopt big data methods, and finally, (vi) a list of practical considerations for researchers seeking to move forward with big data personality measurement and research. It is expected that this paper will provide insights, guidance, and inspiration that helps personality researchers navigate the challenges and opportunities posed by using big data methods in personality measurement. © 2020 European Association of Personality Psychology 相似文献

Current knowledge of suicidal behavior in the Western Pacific region is relatively limited when compared to other areas of the world. This area is characterized by a wide diversity of social, economic, and cultural aspects that do not permit any homogenous reading of suicide phenomena. Data from countries of the region included in this article suggest the existence of important differences among nations in terms of gender, age, and methods of suicide, as well role of mental illness. In addition, the Western Pacific region appears to be affected by higher rates of suicide than other areas in the world, with signs of progressive worsening in recent years and worrying predictions for the next two decades. The Suicide Trends in At‐Risk Territories (START) Study, initiated by the World Health Organization Regional Office in Manila, seeks to research the incidence of both fatal and nonfatal suicidal behavior in countries of the region and to implement interventions for suicide attempters. This ambitious project is expected to standardize data collection procedures and improve the knowledge cultural factors in suicide. 相似文献
