Intergroup research has focused primarily, if not solely, on how an intergroup comparative context primes social categorization. The current research examines how individual differences, in terms of distinct forms of social self (the relational versus collective self), differentially drive social categorization and zero-sum resource allocation across groups nested within a superordinate group. Results show that the relational self exhibited more ingroup-biased allocations than the collective self; superordinate categorization mediated this relationship. Moreover, the relational self showed more ingroup-biased allocations under the condition of intergroup competition than cooperation; whereas the collective self showed equally unbiased allocations under the conditions of intergroup competition and cooperation. Our research suggests that competition worsens nested group relations for the relational self, but not for the collective self.  相似文献

We propose a functional version of extended redundancy analysis that examines directional relationships among several sets of multivariate variables. As in extended redundancy analysis, the proposed method posits that a weighed composite of each set of exogenous variables influences a set of endogenous variables. It further considers endogenous and/or exogenous variables functional, varying over time, space, or other continua. Computationally, the method reduces to minimizing a penalized least-squares criterion through the adoption of a basis function expansion approach to approximating functions. We develop an alternating regularized least-squares algorithm to minimize this criterion. We apply the proposed method to real datasets to illustrate the empirical feasibility of the proposed method.  相似文献

Defined as a mental framework for how individuals interpret and respond to achievement situations, learning goal orientation (LGO) has received increasing attention in organisational research. However, its effect on leadership, especially in contexts absent of formal leadership, remains understudied. Drawing on social exchange theory, we propose and test an individual‐level two‐stage process model of generalised exchange linking LGO and leadership recognition in self‐managed teams. Specifically, we posit that learning‐oriented individuals will tend to feel safer in self‐managed teams, which will enable and sustain their engagement in contextual role behavior. Such behavior, in turn, will be reciprocated with recognition of these individuals as leaders. We use a multiphase, multi‐informant approach (n = 287), and we find that felt safety mediates the effect of LGO on contextual role behavior, but that contextual role behavior alone does not mediate the effect of LGO on leadership recognition. LGO has an indirect effect on leadership recognition through the joint mediation of felt safety and contextual role behavior. Our results offer insight on the link between LGO and leadership, with practical implications for people working in self‐managed teams.  相似文献

Impulsivity is posited to be a key part of the externalizing spectrum during childhood, but this idea has received minimal empirical attention. The goal of the present investigation was to utilize network analysis to determine whether behavioral impulsivity symptoms are key components of the externalizing network across several developmental periods from preschool into adolescence. Participants were 109 preschoolers (64 % male) ages 3 to 6, 237 children (59 % male) ages 6 to 9, 372 children (59 % male) ages 10 to 13, and 357 adolescents (59 % male) ages 13 to 17 and their parents. Parents completed ratings of Attention-Deficit/Hyperactivity Disorder (ADHD) and Oppositional Defiant Disorder (ODD) symptoms on a well-validated rating scale. Network analyses indicated that ADHD and ODD were somewhat differentiated in preschool, becoming united by behavioral impulsivity symptoms during early childhood, and then differentiating into inattention versus externalizing clusters later during childhood and in adolescence. Behavioral impulsivity symptoms were core to the externalizing spectrum across most developmental periods, but core inattentive and ODD symptoms were also identified in line with progressive differentiation. These results suggest the increasing importance of impulsivity symptoms across development, explaining externalizing comorbidity and potentially serving as a viable target for childhood interventions for externalizing problems.  相似文献

Personality Correlates of Workplace Anti-Social Behavior   总被引:1,自引:0,他引:1  
La relation entre le comportement antisocial au travail (ASB) et des traits de personnalité généraux a étéétudiée sur un échantillon composé de 267 salariés coréens. L'ASB au travail a été conceptualiséà partir de deux dimensions, l'ASB dirigée contre les individues (ASBI) et l'ASB dirigée contre l'organisation (ASBO). La personnalité a étéévaluée grâce au Big Five et à un sixième facteur ≪honnêteté-humilité≫ ( Ashton & Lee, 2001 ). Les analyses de régression multiple indiquèrent que l'honnêteté-humilité et l'extraversion jouaient un rôle essentiel dans la prédiction de l'ASBI et de l'ASBO. De plus, Agreeableness était reliée à l'ASBI tandis que Conscientiousness l'était à l'ASBO. On parle aussi de la nécessité d'adopter un modèle optimal des traits de personnalité.
The relationship between workplace Anti-Social Behavior (ASB) and higher-order personality traits was investigated using a sample of 267 Korean employees. Workplace ASB was conceptualized as having two dimensions: ASB directed against individuals (ASBI) and ASB directed against the organization (ASBO). Personality was assessed using adjective measures of the Big Five factors and of a sixth factor, Honesty-Humility ( Ashton & Lee, 2001 ). Multiple regression analyses indicated that Honesty-Humility and Extraversion played prominent roles in predicting both ASBI and ASBO. Also, Agreeableness was related to ASBI, whereas Conscientiousness was related to ASBO. The importance of adopting an optimal framework of personality traits was discussed.  相似文献

An adolescent female with multiple handicaps and a long history of severely disruptive behavior participated in a functional assessment linked directly to specific revisions in her school curriculum. During Phase 1, reversal designs were used to test hypotheses pertaining to antecedent and auricular influences on problem behavior. During Phase 2, a multiple baseline across afternoon and morning time periods demonstrated that the auricular revisions were effective in eliminating severely disruptive behavior and increasing on-task responding. Data also showed that inappropriate “psychotic” speech was reduced and appropriate social interactions were increased. Follow-up results showed that the changes were maintained throughout the school year. Questionnaire data provided social validation of the procedures and outcomes. The findings are discussed in relation to their implications for functional assessment, individualized curricula, and positive programming for students with disabilities and serious behavior problems.  相似文献

This study investigated the most effective way to present an instructional video that contains words in the students' second language. Korean‐speaking university students received a 16‐min video lesson on Antarctica that included English narration (video + narration group), English text subtitles (video + text group), or English narration with simultaneous text subtitles (video + narration + text group). On a comprehension test, the video + text group scored higher than each of the other two groups, in contrast to the modality effect; and the video + narration + text group outscored the video + narration group, in contrast to the redundancy effect. Each of the lessons that included text was rated as less difficult than the lesson with narration only. The narration + text group reported lower effort than each of the other groups. Results highlight boundary conditions for two principles of multimedia instructional design that apply for college students who are learning in a second language. Theoretical implications are discussed.  相似文献

In this research, we investigated the effect of ego depletion on escalation of commitment. Specifically, we conducted two laboratory experiments and obtained evidence that ego depletion decreases escalation of commitment. In Study 1, we found that individuals were less susceptible to escalation of commitment after completing an ego depletion task. In Study 2, we confirmed the effect observed in Study 1 using a different manipulation of ego depletion and a different subject pool. Contrary to the fundamental assumption of bounded rationality that people have a tendency to make decision errors when mental resources are scarce, the findings of this research show that a tired mind can help reduce escalation bias.  相似文献

Bi-ethnic adolescents of marriage migrant mothers in Korea are often encouraged to be “pure” Koreans for their adjustments and not given the opportunities to explore their ethnic identity or to learn about their mother’s culture of origin. Existing studies conducted with mono-ethnic minorities in other countries, however, do not support this belief. We tested a conceptual model on the role of ethnic socialization, ethnic identity and self-esteem on school adjustment among bi-ethnic adolescents in Korea based on social identity theory and theoretical models of ethnic socialization and ethnic identity. We used data from 2015 National Survey of Multicultural Families. The study sample consisted of 296 adolescents aged 9–18 who were born between Korean fathers and Vietnamese marriage migrant mothers. We used structural equation modeling to specifically examine the association between ethnic socialization in terms of parents’ linguistic socialization and adolescents’ school adjustment mediated by ethnic identity in the form of ethnic regard and self-esteem among bi-ethnic adolescents. The results verified the hypothesized model, showing positive relationships between linguistic socialization and ethnic regard, ethnic regard and self-esteem, self-esteem and school adjustment, and ethnic regard and school adjustment. Additionally, the results of bootstrapping test showed that the indirect effect of linguistic socialization on self-esteem through ethnic regard was significant. The indirect effect of ethnic regard on school adjustment through self-esteem was significant and the indirect effect of linguistic socialization on school adjustment via ethnic regard and self-esteem was also significant. These results shed light on the important role of ethnic identity fostered at home among bi-ethnic adolescents of marriage migrant mothers in Korea.  相似文献
