Knowledge about the distribution of information and group decision making: When and why does it work?

Research has shown that decision-making groups with distributed information perform better when group members know which member is knowledgeable about what. Thus far research has been unable to identify the process responsible for this effect. In the present study, we propose that group members’ task representations mediate the effect of knowledge about the distribution of information on decision performance. Building on this proposition, we also propose that reflection about the task moderates the effect of knowledge about distributed information through its effect on task representations. These hypotheses were put to the test in an experimental study of decision-making groups (N = 125). As predicted, knowledge of distributed information interacted with reflection to affect decision quality. Findings confirmed the proposed mediating role of task representations and information elaboration.     

Pooling data versus averaging model fits for some prototypical multinomial processing tree models

For a study with multinomial data where there are n_g individuals and with each person having n_r test trials, the question arises as to how to fit the parameters of a multinomial processing tree (MPT) model. Should each parameter be estimated for each individual and then averaged to obtain a group estimate, or should the frequencies in the multinomial categories be pooled so that the model is fit once for the entire group? This basic question is explored with a series of Monte Carlo simulations for some prototypical MPT models. There is a general finding of a pooling advantage for the case where there is a single experimental condition. Also when there are different experimental conditions, there is reduced bias for detecting condition differences for a method based on the pooled data. Although the focus of the paper is on multinomial models, a general theorem is advanced that establishes a basic condition that determines whether there is or is not a difference between the averaging of individual estimates and the estimate based on the pooled data.     

Impact of Conflict on Mental Health in Northern Ireland: The Mediating Role of Intergroup Forgiveness and Collective Guilt

The aim of the present research was to investigate the mediating role of group-level forgiveness and guilt in the relationship between victimhood (the extent to which the conflict affected an individual's life), exposure to violence (the level of violence in their area of residence), and group identity on the one hand, and mild psychiatric morbidity on the other. Specifically the study focused on the psychological impact of the ethnopolitical conflict in Northern Ireland, utilizing people's identification with either the Catholic or Protestant community. Our results revealed that intergroup forgiveness mediated the relationship between both victimhood and group identification, as predictors, and mild psychiatric morbidity. Collective guilt, on the other hand, mediated the relationship between both exposure to violence and group identification, as predictors, and intergroup forgiveness. Overall this study shows that forgiveness and collective guilt can act as mediators in the relationship between impact of ethnopolitical conflict and mental health, at the group level, and thus demonstrates their centrality to the reconciliation process. Implications for intergroup reconciliation initiatives in Northern Ireland are discussed.     

The role of “dark personalities” (narcissism, Machiavellianism, psychopathy), Big Five personality factors, and ideology in explaining prejudice

The so-called Dark Triad (narcissism, Machiavellianism, psychopathy) represent correlated subclinical personality traits capturing “dark personalities”. How might darker personalities contribute to prejudice? In the present study (n = 197), these dark personality variables correlated positively with outgroup threat perceptions and anti-immigrant prejudice. A proposed two-stage structural equation model, assuming indirect personality effects (Dark Personality, Big Five) on prejudice through ideology and group threat perceptions, fit the data well. Specifically, a latent Dark Personality factor predicted social dominance orientation, whereas (low) Openness to Experience predicted right-wing authoritarianism; these ideological variables each predicted prejudice directly and indirectly through heightened intergroup threat. The authors recommend that personality models of prejudice incorporate both normal-range and subclinical personality predictors, in addition to ideological and social psychological mediators.     

Collective motivation beliefs of early adolescents working in small groups

This study examined collective efficacy, group cohesion, and group performance in 125 randomly assigned groups of older (mean age 13.45 years) and younger (mean age 11.41 years) early adolescents working on three cooperative tasks. Collective motivation significantly predicted performance, even after controlling for past performance and self-efficacy for the older but not the younger participants. For the older (but not the younger) participants, groups with high collective efficacy and group cohesion scored higher on performance tasks than groups with low collective efficacy and group cohesion. The results point to the emergence of collective motivation beliefs in early adolescence, consistent with theories of social and cognitive development. Implications for theory and suggestions for future research are discussed.     

Group status, perceptions of threat, and support for social inequality

Members of high-status groups have been shown to favor social inequality, but little research has investigated the boundary conditions of this phenomenon. In the present article we suggest that perceived intergroup threat moderates the relationship between group status and support for social inequality (i.e., social dominance orientation), especially among highly identified group members. In Study 1, Democrats and Republicans rated their party’s relative status and were later exposed to a leading US. Presidential candidate from the opposing party (high threat) or their own party (low threat). In Study 2, university students were made to believe that their school had high or low status and were then presented with threatening or non-threatening information about a rival institution. The results of both studies supported the prediction that status only increases preferences for group-based inequality under conditions of high threat and high ingroup identification.     

Sanctioned social violence: A psychoanalytic view - Part I

This paper is the first of a series of two that present an effort to systematize the application of psychoanalytic theory of group processes to the outbreak of massive violence. It explores the origins and social amplification of primitive aggression by means of group psychology and mass psychology, and the combined influences of the regressive pull of ideologies, the personality features of social and political leadership, and the triggering impact of historical trauma and social crises. The paper describes a spectrum of narcissistic-paranoid mechanisms that provide a common matrix for the analysis of those aspects of social psychology that co-determine socially sanctioned violence.     

Linking Birth Order to Political Leadership: The Impact of Parents or Sibling Interaction?

Despite mounting evidence that first-born children are overrepresented among incumbents in political office, there is no consensus about the cause of this overrepresentation. Some stress the impact of differential parenting, arguing that the first-born receive a larger share of parental resources and have a greater need to live up to parental expectations. Others emphasize the interaction among siblings, arguing that first-born children are better prepared for power struggles, having experience both as followers and as leaders within the family. This study, using birth-order data for nearly 1,200 incumbents in various offices in local and national politics in the Netherlands, found more support for the parental impact perspective. Singletons were also overrepresented among incumbents, whereas middle-born children were underrepresented. The data suggest that this birth-order effect is weaker among younger generations and is more pronounced among women.     

The Relationship Between Gender Role Stereotypes and Requisite Military Leadership Characteristics

The continuing emphasis on the need to utilize fully women's leadership skills in traditionally or predominantly male environments highlights the need for understanding gender stereotypes and leadership characteristics perceived to be associated with various jobs. This study essentially replicates Schein's research (1973, 1975) to determine the extent of gender stereotypes held by military students for military leadership positions. The results indicate (1) continued disparity in men's perceptions of the similarities between women and leaders, (2) support of previous findings that women recognize similarities between women and leaders, (3) senior military students possess stronger masculine gender role stereotypes of successful officers than do students with less than 1 year of service in the military academy, (4) greater experience with being led by female leaders did not affect men's masculine gender role stereotypes of successful leaders, and (5) successful female cadet leaders perceive successful officers as having characteristics commonly ascribed to both women and men. These results are interpreted in light of previous research on gender roles and leadership, and the practical implications for meeting organizational, and individual objectives for successful utilization of women in military leadership positions are discussed.
