Colors carry meaningful psychological signals. We hypothesized that the color red serves as a powerful cue in competition, affecting both actors and perceivers. Using simplified poker games we investigated the psychological meaning of color in competitive interaction, by examining how the color of chips (red vs. blue or white) used by participants or their competitors affected behavior. Although chip color was objectively unrelated to the chips' value or competitors' strength, perceiving competitors using red chips renders competitors more intimidating, which leads perceivers to withdraw. Furthermore, actors who used red chips felt more dominant, which led them to enhanced competitive approach. Displaying red thus makes actors feel stronger and increases competitive approach; perceivers of displays of red in competitors feel intimidated and withdraw from competing. 相似文献

Loneliness concerns the subjective evaluation that the number of relationships is smaller than the individual considers desirable or that the intimacy that the individual wishes for has not been realized. The aim of this study was to assess variations in levels of late-life loneliness and its determinants across Europe. Data came from the SHARE surveys, Wave 2 (Borsch-Supan et al., 2008), encompassing adults aged 50 years and over in Austria, Belgium, the Czech Republic, Denmark, France, Germany, Greece, Ireland, Italy, the Netherlands, Poland, Spain, Sweden, and Switzerland (N = 12,248). Loneliness was measured by a single item derived from the CES-D (depression) scale. Using logistic models, the present authors tested several types of explanations for country differences: differences in demographic characteristics, wealth and health, and social networks. Older adults in the southern and central European countries were generally lonelier than their peers in the northern and western European countries. In the southern and central European countries, loneliness was largely attributable to not being married, economic deprivation, and poor health. Frequent contacts with parents and adult children, social participation, and providing support to family members were important in preventing and alleviating loneliness in almost all countries. To combat loneliness among older adults, the findings suggest both (a) generic approaches aimed at improving social embeddedness and (b) country-tailored approaches aimed at improving health and wealth. 相似文献

Our ability for scientific reasoning is a byproduct of cognitive faculties that evolved in response to problems related to survival and reproduction. Does this observation increase the epistemic standing of science, or should we treat scientific knowledge with suspicion? The conclusions one draws from applying evolutionary theory to scientific beliefs depend to an important extent on the validity of evolutionary arguments (EAs) or evolutionary debunking arguments (EDAs). In this paper we show through an analytical model that cultural transmission of scientific knowledge can lead toward representations that are more truth-approximating or more efficient at solving science-related problems under a broad range of circumstances, even under conditions where human cognitive faculties would be further off the mark than they actually are. 相似文献

Among many properties distinguishing emergence, such as novelty, irreducibility and unpredictability, computational accounts
of emergence in terms of computational incompressibility aim first at making sense of such unpredictability. Those accounts
prove to be more objective than usual accounts in terms of levels of mereology, which often face objections of being too epistemic.
The present paper defends computational accounts against some objections, and develops what such notions bring to the usual
idea of unpredictability. I distinguish the objective unpredictability, compatible with determinism and entailed by emergence,
and various possibilities of predictability at emergent levels. This makes sense of practices common in complex systems studies
that forge qualitative predictions on the basis of comparisons of simulations with multiple values of parameters. I consider
robustness analysis as a way to ensure the ontological character of computational emergence. Finally, I focus on the property
of novelty, as it is displayed by biological evolution, and ask whether computer simulations of evolution can produce the
same kind of emergence as the open-ended evolution attested in Phanerozoic records. 相似文献

Hedonic overconsumption is often considered to be caused by impulsive factors. The current paper investigates whether self‐licensing, relying on reasons to justify subsequent gratification, can also be included as a significant contributor to hedonic consumption. Two studies were conducted to investigate whether self‐licensing can account for an increase in hedonic consumption while ruling out impulsive factors such as resource depletion, negative affect, and visceral state as alternative explanations. A pilot study indicated that perceiving oneself as having invested greater effort and thus having a self‐licensing cue did not lead to a decline in self‐control capacity compared with not having a self‐licensing cue. The main study employed the same procedure and established that having a licensing cue did lead to increased snack intake while controlling for impulsive factors. Together, these studies support the notion that self‐licensing is a separate mechanism leading to hedonic gratification independent of impulsive factors. Copyright © 2011 John Wiley & Sons, Ltd. 相似文献

The election of the first African‐American President of the United States, Barack Obama, has been widely recognised as an extraordinary milestone in the history of the United States and indeed the world. With the use of a discursive psychological approach combined with central theoretical principles derived from social identity and self‐categorisation theories, this paper analyses a corpus of speeches Obama delivered during his candidacy for president to examine how he attended to and managed his social identity in his political discourse. Building on a social identity model of leadership, we examine specifically how Obama mobilises political support and social identification by building an identity for himself as a prototypical representative of the American people, notwithstanding the protracted public debate within both the White and Black American communities that had questioned and contested Obama's identity. Moreover, we demonstrate how Obama managed the dilemmas around his identity by actively crafting an in‐group identity that was oriented to an increasingly socially diverse America—a diversity that he himself exemplified and embodied as a leader. As an ‘entrepreneur’ of identity, Obama's rhetorical project was to position himself as an exceptional leader, whose very difference was represented as ‘living proof’ of the widely shared collective values that constitute the ‘American Dream’. Drawing on social identity complexity theory, we suggest that by providing more inclusive and complex categories of civic and national identity, Obama's presidency has the potential to radically transform what it means to be a prototypical in‐group member in America.

The present two‐wave longitudinal study addressed the role of affective empathy and parental support in aggressive and delinquent behavior in a sample of 323 adolescents (158 boys, 165 girls). Self‐report questionnaires were used to assess affective empathy, perceived support from parents, delinquency, and aggression. Guided by theories on children's differential susceptibility to socialization, we expected adolescents with different levels of empathy to vary in their responsiveness to parental support. In agreement with our hypothesis, empathy moderated the relation of perceived parental support with aggressive and delinquent behavior. Controlling for the effect of gender and for the stability of aggression and delinquency, higher perceived parental support was predictive of lower levels of aggression at age 15, but only for adolescents high in empathy. Remarkably, adolescents low in empathy not only appeared to benefit less from parental support, but even showed more aggression and delinquency at age 15 when they perceived their parents to be more supportive at age 14.

This paper investigates the conception of causation required in order to make sense of natural selection as a causal explanation
of changes in traits or allele frequencies. It claims that under a counterfactual account of causation, natural selection
is constituted by the causal relevance of traits and alleles to the variation in traits and alleles frequencies. The “statisticalist”
view of selection (Walsh, Matthen, Ariew, Lewens) has shown that natural selection is not a cause superadded to the causal
interactions between individual organisms. It also claimed that the only causation at work is those aggregated individual
interactions, natural selection being only predictive and explanatory, but it is implicitly committed to a process-view of
causation. I formulate a counterfactual construal of the causal statements underlying selectionist explanations, and show
that they hold because of the reference they make to ecological reliable factors. Considering case studies, I argue that this
counterfactual view of causal relevance proper to natural selection captures more salient features of evolutionary explanations
than the statisticalist view, and especially makes sense of the difference between selection and drift. I eventually establish
equivalence between causal relevance of traits and natural selection itself as a cause. 相似文献

Recently, dual models of social cognition have distinguished the implicit (affective) and the explicit (propositional) levels of self-esteem. Many studies have found that implicit and explicit self-esteem are weakly or even not correlated. Concerning the moderating factors of such a relationship, other studies stressed the importance of emotional awareness in the translation of implicit self-evaluations into a propositional format. If so, the defensive strategy which characterizes dismissing attachment should determine a fictitious explicit self-image, by impairing the awareness of self-related emotional experiences. At the implicit level, instead, such defensive processes should not operate. We therefore hypothesized that dismissing attachment would increase the implicit-explicit self-esteem discordance. Participants were 145 university students with a mean age of 20.4 (SD = 2.75). Moderated multiple regression analyses were conducted to test for the interactive effects of the Self-Esteem Implicit Association Test and the Attachment Style Questionnaire scales on the Rosenberg Self-Esteem Scale. Findings revealed an interaction effect only for the relationships as secondary scale, confirming that dismissing style, but not other attachment dimensions, increases implicit-explicit self-esteem discordance. 相似文献
