The individual self comprise unique attributes, the relational self comprises partner-shared attributes, and the collective self comprises ingroup-shared attributes. All selves are fundamental components of the self-concept, with each being important and meaningful to human experience and with each being associated with health benefits. Are the selves, however, equally important and meaningful? We review a program of research that tested four competing theoretical views suggesting that the motivational hub of human experience is (a) the individual self, (b) the relational self, (b) the collective self, or (c) determined by contextual or cultural factors. The research furnished support to the view that the individual self is the primary form of self-definition. We discuss alternative explanations and implications. We end with the introduction of a theoretical model, the boomerang model, that has the potential to integrate the diverse literature on the topic.  相似文献

Using two survey experiments, I reconsider the role that the racialized physical traits and level of assimilation of salient immigrants play in shaping attitudes toward immigration. In the first experiment, a nationwide sample of 767 White, non‐Latino adults was exposed to a story about a family of undocumented immigrants living in the Unites States who were at risk of deportation. Subjects were randomly assigned to view a version of the story in which the immigrants were depicted with light skin and stereotypically Eurocentric features, or dark skin and stereotypically Afrocentric features, and their level of assimilation to mainstream American culture was suggested to be high or low. Similar to previous research, the study's results show that assimilation has a direct effect on attitudes toward immigration. Yet in contrast to previous studies, the racialized physical traits proved to be a much more important factor in shaping attitudes toward immigration than previously demonstrated. The role of an immigrant's racialized physical traits was replicated in a second survey experiment of 902 White, non‐Latino adults. Overall, the findings shed new light on how media depictions of immigrants are affecting immigration attitudes, as well as the nuanced ways that race continues to shape public opinion in the United States today.  相似文献

This study investigated the relation between theory of mind and reactive and proactive aggression, respectively, as well as the moderating role of peer victimization in this context. The 574 participants were drawn from a longitudinal study of twins. Theory of mind was assessed before school entry, when participants were 5 years old. Reactive and proactive aggression as well as peer victimization were assessed a year later in kindergarten. Results from multilevel regression analyses revealed that low theory of mind was related to a high level of reactive aggression, but only in children who experienced average to high levels of peer victimization. In contrast, a high theory of mind was related to a high level of proactive aggression. Again, this relation was especially pronounced in children who experienced high levels of peer victimization. These findings challenge the social skills deficit view of aggression and provide support for a multidimensional perspective of aggressive behavior.  相似文献

This study examined whether clique isolation predicted an increase in depressive symptoms and whether this association was mediated by loneliness and perceived social acceptance in 310 children followed from age 11–14 years. Clique isolation was identified through social network analysis, whereas depressive symptoms, loneliness, and perceived social acceptance were assessed using self ratings. While accounting for initial levels of depressive symptoms, peer rejection, and friendlessness at age 11 years, a high probability of being isolated from cliques from age 11 to 13 years predicted depressive symptoms at age 14 years. The link between clique isolation and depressive symptoms was mediated by loneliness, but not by perceived social acceptance. No sex differences were found in the associations between clique isolation and depressive symptoms. These results suggest that clique isolation is a social risk factor for the escalation of depressive symptoms in early adolescence. Implications for research and prevention are discussed.  相似文献

The goal of the present study was to test the moderating role of Locus of Control beliefs on performance deficits typically associated with stereotype threat. The results from Experiment 1 were consistent with predictions. First, consistent with the Stereotype Threat model, participants showed a decrease in performance when the task was perceived as a potential test of the in‐group's negative stereotype (lacking logical mathematical intelligence in the case of women and lacking social intelligence in the case of men). Most important, participants' Locus of Control beliefs were found to moderate participants' vulnerability to stereotype threat: individuals with an Internal Locus of Control, although generally performing better, showed a sharper decrease in the stereotype threat condition compared to individuals with External Locus of Control beliefs. Experiment 2 replicated the results from Experiment 1. Findings are discussed in relation to the psychological characteristics of Internal Locus of Control that may render individuals more vulnerable to the negative effects of stereotype threat.

Previous research has established two-way relationships among negotiators’ motivational orientations, strategy choices, and outcomes. This article focuses on the less often investigated three-way relationship among these variables. A log-linear analysis demonstrated that in individualistically oriented dyads, low joint gain was associated with high levels of substantiation, demand, and proposal modifications. Joint gain improved when negotiators made multi-issue offers, used positional arguing, and introduced non-reciprocal sequences based on priority information. In cooperatively oriented dyads, high levels of priority information, process management, and reciprocal sequences characterized optimum outcomes. We conclude that optimum outcomes result from (a) multi-issue offers and indirect information under an individualistic orientation and (b) reciprocity and direct information under a cooperative orientation.  相似文献

The present study examined (a) the predictive effect of disruptive boys' attendance to a prevention program (i.e., dosage) on post-intervention academic achievement and behavior and (b) the potential moderating effects of child and family characteristics in this context. The 3-year intervention program included reading, self-regulation, and social skills training for the boys, parental support and skills training for parents, and teacher support. A multiple-screening procedure selected 58 disruptive, low socioeconomic status boys at the age of 6 years for program participation. Multiple regression analyses and logistic regression analyses showed that the number of program sessions attended did not contribute to the prediction of boys' post-intervention disruptive behavior. However, the number of attended sessions was positively related to boys' post-intervention likability, as well as to their post-intervention writing, reading, math, and human science performances. Interaction terms revealed that family constellation moderated the link between program dosage and likability and math success, respectively, whereas boys' IQ moderated the links between dosage and boys' success in writing and math. The discussion stresses the importance of dosage-effect analysis and the examination of moderating variables in this context.  相似文献

The fear conditioning paradigm is used to investigate the roles of various genes, neurotransmitters, and substrates in the formation of fear learning related to contextual and auditory cues. In the brain, nitric oxide (NO) produced by neuronal nitric oxide synthase (nNOS) functions as a retrograde neuronal messenger that facilitates synaptic plasticity, including the late phase of long-term potentiation (LTP) and formation of long-term memory (LTM). Evidence has implicated NO signaling in synaptic plasticity and LTM formation following fear conditioning, yet little is known about the role of the nNOS gene in fear learning. Using knockout (KO) mice with targeted mutation of the nNOS gene and their wild-type (WT) counterparts, the role of NO signaling in fear conditioning was investigated. Plasma levels of the stress hormone corticosterone were measured to determine the relationship between physiological and behavioral response to fear conditioning. Contextual fear learning was severely impaired in male and female nNOS KO mice compared with WT counterparts; cued fear learning was slightly impaired in nNOS KO mice. Sex-dependent differences in both contextual and cued fear learning were not observed in either genotype. Deficits in contextual fear learning in nNOS KO mice were partially overcome by multiple trainings. A relationship between increase in plasma corticosterone levels following footshock administration and the magnitude of contextual, but not cued freezing was also observed. Results suggest that the nNOS gene contributes more to optimal contextual fear learning than to cued fear learning, and therefore, inhibition of the nNOS enzyme may ameliorate context-dependent fear response.Anxiety disorders, such as post-traumatic stress disorder (PTSD), constitute the most prevalent mental illnesses in the United States, costing nearly one-third of the country''s total health bill (Greenberg et al. 1999). The treatment of these disorders requires overcoming complications such as reluctance to seek mental health treatment and an extremely high comorbidity rate with other affective disorders, reaching 80% (Brady 1997; Solomon and Davidson 1997). Emerging evidence suggests that dysfunctions underlying acquired anxiety and PTSD include an abnormal reaction to stress, which is mediated by specific neurochemical and neuroanatomical substrates (Yehuda and McFarlane 1995; Adamec 1997). Pharmacotherapies that target neuronal signaling molecules, such as nitric oxide (NO), may play a role in the treatment of these disorders.In the brain, N-methyl-d-aspartate receptor (NMDAR) activation and calcium influx into the cell activates the neuronal nitric oxide synthase (nNOS) enzyme to produce NO, which has the role of retrograde messenger (Snyder 1992). NO is involved in memory formation and synaptic plastic events such as late-phase long-term potentiation (LTP) (Lu et al. 1999; Arancio et al. 2001; Puzzo et al. 2006). Behavioral evidence in invertebrates (Lewin and Walters 1999; Muller 2000; Kemenes et al. 2002; Matsumoto et al. 2006) and vertebrates (Medina and Izquierdo 1995; Rickard et al. 1998; Ota et al. 2008) suggest that NO has a major role in consolidation of long-term memory (LTM). Recently, studies have shown that site-specific pharmacological blockade of NO signaling in rats impairs contextual (Resstel et al. 2008) and cued (Schafe et al. 2005) fear learning. However, the role of the nNOS gene in fear conditioning has not been investigated.In the present study, fear conditioning was investigated in homozygous nNOS knockout (KO) and wild-type (WT) mice. In the fear-conditioning paradigm, the association of a footshock (unconditioned stimulus; US), with a specific context and a neutral stimulus (auditory cue) results in learned fear. Re-exposure to the conditioning context and to the previously neutral auditory cue (conditioned stimulus; CS) elicits a freezing response in the absence of the aversive US. Thus, the fear-conditioning paradigm includes both contextual and cued fear learning components, which can be measured in separate tests. Fear conditioning recruits both the amygdala (emotional cue learning) and the hippocampus (spatial/contextual learning) (Phillips and LeDoux 1992; Goosens and Maren 2004; Mei et al. 2005). The involvement of these brain regions in fear learning and anxiety has been confirmed by animal and human imaging studies (LeDoux 1998; Rauch et al. 2006).We report that nNOS KO mice showed a severe deficiency in contextual fear learning and a less marked deficit in cued fear learning compared with WT mice after a single fear-conditioning session. This deficiency was partially improved by multiple (four) fear-conditioning sessions. In addition, we observed that plasma levels of corticosterone, the primary stress hormone in rodents, are related to contextual fear learning ability.  相似文献

Role and market forces provide two sources of power that affect negotiated outcomes. To test their effects, 48 subjects participated in one of two negotiation markets that favored either buyers or sellers. Profit was influenced by both power sources: Buyers outperformed sellers, and negotiators in a favorable market outperformed negotiators in an unfavorable market. This effect was shown to be additive, indicating that the effects of the two sources of power were independent of one another. Whereas negotiators advantaged by market forces showed increases in profit over time, profits for negotiators disadvantaged by the market remained stable. Joint profit rose throughout both markets. However, this did not reflect increasing integrativeness in the markets; rather, the increase could be attributed to increases in high power negotiator profits. Markets became more distributive over time, and both the effectiveness and efficiency of bargaining decreased, particularly in the market favoring buyers.  相似文献
