The Benefits,Costs, and Paradox of Revenge

In this article, we examine the psychology of revenge. We begin by discussing challenges associated with defining revenge. We then review the relative costs and benefits associated with taking revenge. Although revenge can deter future harm, promote cooperation, and restore avengers’ self-worth and power, it can also contribute to conflict escalation and adverse psychological outcomes for avengers, such as depression and reduced life satisfaction. Next, we examine the prevalence of revenge. In distinguishing between the desire for revenge and act of revenge, we challenge the notion that the act of revenge is an automatic or pervasive response to injustice. We highlight four factors that influence whether victims of injustice choose to take revenge: the persistence of anger, perceptions of the costs of revenge, cultural and religious values regarding revenge, and the presence of external systems that can restore justice on behalf of victims.     

Paradoxical olfactory function in combat Veterans: The role of PTSD and odor factors

Stress- and trauma-related disorders, including posttraumatic stress disorder (PTSD), are characterized by an increased sensitivity to threat cues. Given that threat detection is a critical function of olfaction and that combat trauma is commonly associated with burning odors, we sought a better understanding of general olfactory function as well as response to specific trauma-related (i.e. burning) odors in combat-related PTSD. Trauma-exposed combat Veterans with (n = 22) and without (n = 25) PTSD were assessed for general and specific odor sensitivities using a variety of tools. Both groups had similar general odor detection thresholds. However, the combat Veterans with PTSD, compared to combat Veterans with comparable trauma exposure but without PTSD, had increased ratings of odor intensity, negative valence, and odor-triggered PTSD symptoms, along with a blunted heart rate in response to burning rubber odor. These findings are discussed within the context of healthy versus pathological changes in olfactory processing that occur over time after psychological trauma.     

Intellectual humility and openness to the opposing view

Strong disagreements have stymied today’s political discourse. We investigate intellectual humility – recognizing the limits of one’s knowledge and appreciating others’ intellectual strengths – as one factor that can make disagreements more constructive. In Studies 1 and 2, participants with higher intellectual humility were more open to learning about the opposition’s views during imagined disagreements. In Study 3, those with higher intellectual humility exposed themselves to a greater proportion of opposing political perspectives. In Study 4, making salient a growth mindset of intelligence boosted intellectual humility, and, in turn, openness to opposing views. Results suggest that intellectual humility is associated with openness during disagreement, and that a growth mindset of intelligence may increase intellectual humility. Implications for current political polarization are discussed.     

"I'm attached, and I'm a good guy/gal!": how character attachment influences pro- and anti-social motivations to play massively multiplayer online role-playing games

One's feelings of intimacy and connectedness with distal, fictional media characters are referred to as parasocial interactions. Video games have challenged this concept, as the distance between game players and characters is greatly reduced, if not completely removed, in virtual environments. Games encourage the internalization and psychological merging of a player's and a character's mind, a multidimensional concept known as character attachment (CA). Data from our study suggest that dimensions of CA are useful in understanding both pro- and anti-social gaming motivations. Pro-social gamers feel a greater sense of control over their characters, while anti-social gamers are more likely to suspend their disbelief of the game environment and not take responsibility for their virtual actions. Pro-social gaming was more prevalent in older gamers, and younger male game characters were motivated by anti-social reasons.     

(Re)assembling Natures,Cultures, and (Nano)technologies in Public Engagement

Abstract

Practices of ordering are powerful means of giving structure to people's lives and providing a sense of control. The analysis of three episodes from discussion groups on nanotechnology in Austria shows that citizens evaluate new technologies with regard to how they intersect with, support, or disturb existing orders. The concept of discursive assemblages serves as a lens for recognising the non-fixed character of the discursive process, while still allowing the analyst to identify how specific elements, such as conceptions of nature, culture, and technology, are (re)assembled at particular moments. Each of the three episodes represents a specific way of creating and negotiating assemblages: the first case demonstrates how discussants collectively discuss a nature–technology hybrid (nano-bamboo socks) against the backdrop of a highly valued ideal of keeping ‘the natural’ and ‘the technological’ separate; the second episode exemplifies a clash of two assemblages as participants argued for or against the application of nanotechnology in food products; and the third example illustrates the process of collective experimentation with different assemblages to make sense of a highly futuristic nanochip for brain enhancement. Together the episodes demonstrate that participants in public engagement settings do not address nanotechnology as a simple question of choice between acceptance and rejection but rather engage in processes of care regarding how a society might develop when technological innovations such as nanotechnology threaten to blur existing boundaries and orders, such as the distinction between nature and culture.     

Drugs as instruments: a new framework for non-addictive psychoactive drug use

Most people who are regular consumers of psychoactive drugs are not drug addicts, nor will they ever become addicts. In neurobiological theories, non-addictive drug consumption is acknowledged only as a "necessary" prerequisite for addiction, but not as a stable and widespread behavior in its own right. This target article proposes a new neurobiological framework theory for non-addictive psychoactive drug consumption, introducing the concept of "drug instrumentalization." Psychoactive drugs are consumed for their effects on mental states. Humans are able to learn that mental states can be changed on purpose by drugs, in order to facilitate other, non-drug-related behaviors. We discuss specific "instrumentalization goals" and outline neurobiological mechanisms of how major classes of psychoactive drugs change mental states and serve non-drug-related behaviors. We argue that drug instrumentalization behavior may provide a functional adaptation to modern environments based on a historical selection for learning mechanisms that allow the dynamic modification of consummatory behavior. It is assumed that in order to effectively instrumentalize psychoactive drugs, the establishment of and retrieval from a drug memory is required. Here, we propose a new classification of different drug memory subtypes and discuss how they interact during drug instrumentalization learning and retrieval. Understanding the everyday utility and the learning mechanisms of non-addictive psychotropic drug use may help to prevent abuse and the transition to drug addiction in the future.     

To use or not to use: Expanding the view on non-addictive psychoactive drug consumption and its implications

Proposing a change to the view on psychoactive drug use in non-addicts touches a sensitive issue because of its potential implications to addiction prevention, therapeutic practice, and drug policy. Commentators raised nine questions that ranged from clarifications, suggested extensions of the model to supporting data previously not regarded, to assumptions on the implications of the model. Here, we take up the suggestions of the commentators to expand the model to behavioral addictions, discuss additional instrumentalization goals, and review the evidence from laboratory animal studies on drug instrumentalization. We consider further the role of sociocultural factors and individual development in the establishment in drug instrumentalization and addiction. Finally, we clarify which implications we think this model may have. We conclude that drug instrumentalization theory can be further applied to other behaviors but will require a sensitive debate when used for drug and addiction policy that directly affects prevention and treatment.     

A nonparametric method to analyze interactions: The adjusted rank transform test

Experimental social psychologists routinely rely on ANOVA to study interactions between factors even when the assumptions underlying the use of parametric tests are not met. Alternative nonparametric methods are often relatively difficult to conduct, have seldom been presented into detail in regular curriculum and have the reputation - sometimes incorrectly - of being less powerful than parametric tests. This article presents the adjusted rank transform test (ART); a nonparametric test, easy to conduct, having the advantage of being much more powerful than parametric tests when certain assumptions underlying the use of these tests are violated. To specify the conditions under which the adjusted rank transform test is superior to the usual parametric tests, results of a Monte Carlo simulation are presented.     

Psychometric properties of the Self-Perception Profile for Children in a biracial cohort of adolescent girls: the NHLBI Growth and Health Study

The National Heart, Lung, and Blood Institute Growth and Health Study (NGHS) is an epidemiologic study of 1,213 Black and 1,166 White girls (ages 9-10) of risk factors for obesity. NGHS used Harter's Self-Perception Profile for Children (SPPC) to measure domain-specific competence and overall self-worth. This report reviews the psychometric properties of the SPPC in this biracial cohort at baseline and Year 3 visits (ages 11-12). Simple structure yielding unique components for each of the SPPC domains was obtained for White but not Black girls, whether analyzed overall or by parental education level. Internal consistency was higher for White girls in both years. The lack of simple structure was reflected in the higher correlations among the subscales for Black girls. The structure and internal consistency improved in Year 3 for Black girls, indicating that the physical appearance and athletic competence domains were not yet fully differentiated at baseline. Readers should be cautious, however, when interpreting the SPPC in young Black girls.
