„Accounting for socioeconomic and demographic variables as well as country specific effects, households’ willingness to pay for changes in climate is revealed using European data on reported life satisfaction. Individuals located in areas with lower average levels of sunshine and higher average levels of relative humidity are less satisfied as are individuals in locations subject to significant seasonal variation in monthly mean temperatures and rain days. Ranking regions according to the preferred climates households appear strongly to favour the Mediterranean climate over the climate of Northern Europe.“

„Low socioeconomic status (SES) is a reliable correlate of poor physical health. Rather than treat SES as a covariate, health psychology has increasingly focused on the psychobiological pathways that inform understanding why SES is related to physical health. This review assesses the status of research that has examined stress and its associated distress, and social and personal resources as pathways. It highlights work on biomarkers and biological pathways related to SES that can serve as intermediate outcomes in future studies. Recent emphasis on the accumulation of psychobiological risks across the life course is summarized and represents an important direction for future research. Studies that test pathways from SES to candidate psychosocial pathways to health outcomes are few in number but promising. Future research should test integrated models rather than taking piecemeal approaches to evidence. Much work remains to be done, but the questions are of great health significance.“
„The studies reported here provide, for the first time, experimental evidence to support the claim that sexual interest and arousal are associated with motives to form and maintain a close relationship. In five studies, sex-related representations were cognitively primed, either subliminally or supraliminally, by exposing participants to erotic words or pictures as compared with neutral words or pictures. The effects of “sexual priming” on the tendencies to initiate and maintain a close relationship were assessed using various cognitive–behavioral and self-report measures. Supporting the hypotheses, subliminal but not supraliminal exposure to sexual primes increased (a) willingness to self-disclose, (b) accessibility of intimacy-related thoughts, (c) willingness to sacrifice for one’s partner, and (d) preference for using positive conflict-resolution strategies. The article discusses implications of these findings for the role of sex in close relationships and offers a conceptualization of possible relational motives of the sexual behavioral system.“
„This paper presents an experiment measuring how lab-induced income inequality affects trust and trustworthiness. Low endowment subjects paired with high endowment subjects showed more trust than subjects in other pairs; this trust was reciprocated with high trustworthiness.“
„The matching hypothesis predicts that individuals on the dating market will assess their own self-worth and select partners whose social desirability approximately equals their own. It is often treated as well established, despite a dearth of empirical evidence to support it. In the current research, the authors sought to address conceptual and methodological inconsistencies in the extant literature and to examine whether matching occurs as defined by Walster et al. and more generally. Using data collected in the laboratory and from users of a popular online dating site, the authors found evidence for matching based on self-worth, physical attractiveness, and popularity, but to different degrees and not always at the same stage of the dating process.“
„The presence of subtle cues of being watched has been reported to make people behave altruistically, even when they are anonymous. Individual selection theory predicts that generosity in the presence of eyes is based on the providers’ expectation of a future reward. On the other hand, as we are living in quite a large society in which altruistic punishment is effective, the eyes could elicit fear of punishment. However, no previous study has investigated whether people are concerned with their reputation when subtle social cues are present. We conducted the dictator game in the presence of, or without, a painting of stylized eyes. The participants were then asked to complete a post-experimental questionnaire designed to investigate what they were thinking when they decided the amount of money to offer the recipient and how they perceived the experimental situation. Participants in the eye condition allocated more money to the recipient than did those in the control condition. This effect was not mediated by fear of punishment but by the expectation of a reward. Moreover, the results suggested that the participants expected their actions would enhance their reputation in the eyes of a third party.“

„Humans and animals prefer immediate over delayed rewards (delay discounting). This preference for smaller-but-sooner over larger-but-later rewards shows substantial interindividual variability in healthy subjects. Moreover, a strong bias towards immediate reinforcement characterizes many psychiatric conditions such as addiction and attention-deficit hyperactivity disorder. We discuss the neural mechanisms underlying delay discounting and describe how interindividual variability (trait effects) in the neural instantiation of subprocesses of delay discounting (such as reward valuation, cognitive control and prospection) contributes to differences in behaviour. We next discuss different interventions that can partially remedy impulsive decision-making (state effects). Although the precise neural mechanisms underlying many of these modulating influences are only beginning to be unravelled, they point towards novel treatment approaches for disorders of impulse control.“

„Altruistic punishment may promote cooperation, but can also lead to costly feuds. We examine how the threat of feuds affects individuals’ willingness to engage in altruistic punishment in a public good experiment in which the number of stages is determined by participants’ actions. The design imposes minimal restrictions on who can punish whom and when, and therefore allows participants to use a range of punishment strategies. We find that participants recognize the threat of feuds and respond to it by employing strategies that prevent their breakout. When feuds can span several periods, the extent of altruistic punishment is greatly reduced. This leads to progressively lower levels of cooperation and earnings relative to a baseline treatment where punishment cannot be avenged.“
„People have present-biased preferences: they choose more impatiently when choosing between an immediate reward and a delayed reward, than when choosing between a delayed reward and a more delayed reward. Following McClure et al. [McClure, S.M., Laibson, D.I., Loewenstein, G., Cohen, J.D. (2004). Separate neural systems value immediate and delayed monetary rewards. Science, 306, 503.], we find that areas in the dopaminergic reward system show greater activation when a binary choice set includes both an immediate reward and a delayed reward in contrast to activation measured when the binary choice set contains only delayed rewards. The presence of an immediate reward in the choice set elevates activation of the ventral striatum, pregenual anterior cingulate cortex and anterior medial prefrontal cortex. These dopaminergic reward areas are also responsive to the identity of the recipient of the reward. Even an immediate reward does not activate these dopaminergic regions when the decision is being made for another person. Our results support the hypotheses that participants show less affective engagement (i) when they are making choices for themselves that only involve options in the future or (ii) when they are making choices for someone else. As hypothesized, we also find that behavioral choices reflect more patience when choosing for someone else.“

„This article introduces the reader to organizational neuroscience, an emerging area of scholarly dialogue that explores the implications of brain science for workplace behavior. The authors begin by discussing how going inside the brain adds new levels of analysis that can advance and connect theories of organizational behavior. They then present three concrete examples of what an organizational neuroscience perspective can achieve by extending current theory, providing new research directions, and resolving ongoing theoretical debates. Last, the authors address a number of deeper metatheoretical questions raised by neuroscience, concluding that it brings new insights that will force scholars to rethink their concept of human nature.“
„Given that we live in highly complex social environments, many of our most important decisions are made in the context of social interactions. Simple but sophisticated tasks from a branch of experimental economics known as game theory have been used to study social decision-making in the laboratory setting, and a variety of neuroscience methods have been used to probe the underlying neural systems. This approach is informing our knowledge of the neural mechanisms that support decisions about trust, reciprocity, altruism, fairness, revenge, social punishment, social norm conformity, social learning, and competition. Neural systems involved in reward and reinforcement, pain and punishment, mentalizing, delaying gratification, and emotion regulation are commonly recruited for social decisions. This review also highlights the role of the prefrontal cortex in prudent social decision-making, at least when social environments are relatively stable. In addition, recent progress has been made in understanding the neural bases of individual variation in social decision-making.“

„Current research on culture focuses on independence and interdependence and documents numerous East-West psychological differences, with an increasing emphasis placed on cognitive mediating mechanisms. Lost in this literature is a time-honored idea of culture as a collective process composed of cross-generationally transmitted values and associated behavioral patterns (i.e., practices). A new model of neuro-culture interaction proposed here addresses this conceptual gap by hypothesizing that the brain serves as a crucial site that accumulates effects of cultural experience, insofar as neural connectivity is likely modified through sustained engagement in cultural practices. Thus, culture is “embrained,” and moreover, this process requires no cognitive mediation. The model is supported in a review of empirical evidence regarding (a) collective-level factors involved in both production and adoption of cultural values and practices and (b) neural changes that result from engagement in cultural practices. Future directions of research on culture, mind, and the brain are discussed.“

„Over the last few years, microblogging has gained prominence as a form of personal broadcasting media where information and opinion are mixed together without an established order, usually tightly linked with current reality. Location awareness and promptness provide researchers using the Internet with the opportunity to create “psychological landscapes“—that is, to detect differences and changes in voiced (twittered) emotions, cognitions, and behaviors. In our article, we present iScience Maps, a free Web service for researchers, available from http://maps.iscience.deusto.es/ and http://tweetminer.eu/. Technologically, the service is based on Twitter’s streaming and search application programming interfaces (APIs), accessed through several PHP libraries, and a JavaScript frontend. This service allows researchers to assess via Twitter the effect of specific events in different places as they are happening and to make comparisons between cities, regions, or countries regarding psychological states and their evolution in the course of an event. In a step-by-step example, it is shown how to replicate a study on affective and personality characteristics inferred from first names (Mehrabian & Piercy, Personality and Social Psychology Bulletin, 19, 755–758 1993) by mining Twitter data with iScience Maps.Results from the original study are replicated in both world regions we tested (the western U.S.and the U.K.); we also discover base rate of names to be a confound that needs to be controlled for in future research.“
„Many adults have an overly pessimistic view of old age because they fail to correctly predict their ability to hedonically adapt to old-age health related problems. A standard utility model where the marginal utility of health is higher at a lower level of health predicts that this overly pessimist view raises the incentive for healthy behavior. But this is at odds with empirical research that indicates that people with more negative aging stereotypes tend to adopt less healthy practices, transforming this negative view into a self-fulfilling prophecy. The aim of this note is to show that this fatalistic behavior can be explained through prospect theory by modelling this overly pessimistic view of old age as a failure to predict the change in the reference point due to hedonic adaptation. Given the diminishing sensitivity in the loss domain, people undervalue the future marginal value of health investment and may therefore underinvest in health as long as loss aversion is not too strong.“
