MODELING RELATIONS

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.     

An analysis of the selective effects of NCR with punishment targeting problem behavior associated with positive affect

Among individuals with developmental disabilities and behavioral problems, self‐injury and aggression are often associated with negative affect such as crying. In the current report, we present data on two children who displayed problem behaviors (screaming and self‐injury) that were often associated with positive affect. In contrast to their other problem behaviors that were socially mediated, these behaviors were maintained independent of social consequences. One concern about treating problem behavior associated with positive affect is that the treatment may produce generalized reductions in positive affect. In both cases presented in the current study, the reductive effects of a treatment targeting these behaviors were highly selective, producing decreases in screaming and self‐injury, while minimally affecting affect.

When Arousal Influences Ad Evaluation and Valence Does Not (and Vice Versa)

This research examines, across 2 studies, the interplay between the valence and arousal components of affective states and the affective tone of a target ad. In the first study, music was used to induce a pleasant or unpleasant mood, while controlling for arousal. Participants were subsequently exposed to an ad that either had a positive‐affective tone or was ambiguous in its affective tone. As predicted, the valence of the affective state colored the evaluation of the ad in a mood‐congruent direction, but this coloring effect occurred only when the ad had an ambiguous‐affective tone. In the second study, the target ad had a clear positive or negative affective tone, and the valence and arousal dimensions of the mood state were manipulated independently. As predicted, the arousal dimension, but not the valence dimension, influenced ad evaluation. Ad evaluations were more polarized in the direction of the ad's affective tone under high arousal than under low arousal. This effect was more pronounced for self‐referent evaluations (e.g., “I like the ad”) than for object‐referent evaluations (e.g., “The ad is good”), favoring an attributional explanation—the excitation transfer hypothesis—over an attention‐narrowing explanation—the dynamic complexity hypothesis. Taken together, the results of the 2 studies stress the important contingency of the affective tone of the ad, when examining the effects of the valence and arousal dimensions of a person's affective state on ad evaluation. The results also provide additional insights into how and when affect serves as information in judgment processes.     

Political Implications of Psychological Research on Ecological Justice and Proenvironmental Behaviour

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.     

Rough‐and‐tumble play and the regulation of aggression: an observational study of father–child play dyads

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.

The Impact of Third Places on Community Quality of Life

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.     

Using Big Data and Machine Learning in Personality Measurement: Opportunities and Challenges

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     

Suicidal Behavior in the Western Pacific Region: Characteristics and Trends

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.
