Towards a synthetic model of own group biases in face memory

In the current work, we extend the Categorization-Individuation Model (Hugenberg, Young, Bernstein, & Sacco, 2010)—an existing model of the own race bias—to organize and explain the proliferation of own group biases in face memory. In this model, we propose that own group biases result from the coacting processes of social categorization,motivation to individuate, and individuation experience. This extended Categorization-Individuation Model affords a number of benefits. First, this model allows us to begin to consider various own group biases as manifestations a single class of phenomena, offering sensible predictions across and among biases. Further, this extended Categorization-Individuation Model makes novel predictions for how own group biases can be exacerbated and eliminated by both perceptual and motivational processes, allowing for potentially novel interventions forown group biases. Finally,we discuss a variety of open questions with regard to an extended Categorization-Individuation Model, with an eye towards framing future research questions.     

Testing relations between group cohesion and satisfaction in project teams: A cross-level and cross-lagged approach

Based on a two-dimensional perspective of group cohesion, this study examines the emergence of task cohesion and interpersonal cohesion in project teams and their roles in changes in members’ individual satisfaction with the team. Specifically, we tested a direct-effect and mediation model of the cross-level relationship between team task and interpersonal cohesion and individual satisfaction with the team over time. With a sample of 74 newly created project teams, the hypotheses were tested using a two-wave panel design. Results indicate that task cohesion emerges more strongly than interpersonal cohesion during the first stages of work in project teams. Moreover, the cross-lagged relationship between team interpersonal cohesion and individual satisfaction with the team was mediated by team task cohesion.     

Cross‐level interactions of individual trait positive affect,group trait positive affect,and group positive affect diversity

The purpose of the current study is to examine the cross‐level three‐way interactions among individual trait positive affect (PA), group trait PA, and group PA diversity on individual work outcomes. Drawing on situation strength theory, we hypothesized that the relationship of individual trait PA with work outcomes depends on the strength of a group's affective contexts including group trait PA and PA diversity. The hierarchical linear modelling results for 261 employees in 42 South Korean organizational teams showed that individuals' trait PA was positively associated with their team commitment, job satisfaction, and organizational citizenship behaviour (OCB). The findings also demonstrated that individual trait PA had the strongest relationship with team commitment when group trait PA was low and PA diversity was high simultaneously. In addition, the relationship between individual trait PA and OCB was found to be stronger for affectively diverse groups than for homogeneous groups.     

Relative deprivation based on occupation: An effective predictor of Chinese life satisfaction

Relative deprivation (RD) refers to the fact that individuals may feel deprived of some desirable thing in social comparison relative to a reference group. Occupational group is widely recognized as the essential reference group and generally used to compare differences in earnings and social position. Four waves' data from the Social Attitudes Survey of Urban‐Rural Residents (China) (SAS‐C; 2005/2007/2008/2009) were used to compute to Stewart's new measure of RD for different occupational groups and its relationship to life satisfaction (a cognitive component of subjective well‐being). Results showed that both economic RD (defined as individuals' RD of material benefits, such as income, wealth etc.) and social status RD (defined as individuals' RD on their evaluation of social status) consistently predicted Chinese life satisfaction for a period of time from 2005 to 2009; meanwhile, individual economic RD was moderately correlated to social status RD. The effects of RD and some demographic variables on life satisfaction are discussed and possible improvements for future research are suggested.     

Category assignment and relatedness in the group ideation process

When groups gather to generate creative ideas on a particular topic, they can consider many aspects or components of the problem. Because such a multitude of alternatives can be overwhelming, groups may find it helpful to focus on specific aspects or categories of the problem. However, it is not clear whether it is best for group members to focus on the same components of the problem at the same time or whether it is better for group members to focus on different components of the problem. Furthermore, the impact of this type of focus may depend on the extent to which the different components of the problem are closely related semantically. It may be easier to generate ideas in semantically related areas but semantically unrelated areas may stimulate generation of more creative ideas. The present study provided a comprehensive test of the effects of task components or category assignment and the degree of relatedness of the assigned categories on the creativity of groups. Groups that were jointly assigned a small set of categories to focus on at the beginning of their session generated more ideas, explored more categories and exhibited higher clustering of similar ideas than the groups whose members were assigned their own unique category. The groups assigned with low related categories surveyed more categories than those assigned with categories of high relatedness. This study suggests that interdisciplinary or diverse groups or teams should have some common focus in the initial phase of their creative sessions and focus on unrelated aspects of the problem in this phase.     

Effects of Quantity and Quality Instructions on Brainstorming

One of the basic presumptions of brainstorming is that a focus on generating a large number of ideas enhances both the number of ideas generated and the number of good ideas (original and useful). Prior research has not clearly demonstrated the utility of such a quantity focus in comparison to a condition in which quantity is not emphasized. There have been some comparisons of the impact of quantity and quality focus on the number and quality of ideas, but the results of these comparisons have been mixed. The present study examined brainstorming with four different types of instructions: no specific focus, a quantity goal, a quality goal, or a joint quantity and quality goal. The quantity goal condition was superior to the other three conditions in leading to the generation of more ideas and more good ideas. These findings support Osborn's (1953) assumption that a quantity focus is most beneficial for brainstorming.     

Right hemisphere dominance for emotion processing in baboons

Asymmetries of emotional facial expressions in humans offer reliable indexes to infer brain lateralization and mostly revealed right hemisphere dominance. Studies concerned with oro-facial asymmetries in nonhuman primates largely showed a left-sided asymmetry in chimpanzees, marmosets and macaques. The presence of asymmetrical oro-facial productions was assessed in Olive baboons in order to determine the functional cerebral asymmetries. Two affiliative behaviors (lipsmack, copulation call) and two agonistic ones (screeching, eyebrow-raising) were recorded. For screeching, a strong and significant left hemimouth bias was found, but no significant bias was observed for the other behaviors. These results are discussed in the light of the available literature concerning asymmetrical oro-facial productions in nonhuman primates. In addition, these findings suggest that human hemispheric specialization for emotions has precursors in primate evolution.     

Output order reflects the cognitive accessibility of goals

Goal accessibility--the ease or speed with which a goal is activated--increases the likelihood that it will be acted on. The present studies validate output order as a measure of goal accessibility that can be applied to goal lists in both laboratory and naturalistic settings. In three studies, output order (the order in which goals are listed in a free-response format) was related to self-reported goal value but was not redundant with it. Furthermore, output order was affected by motivational priming whereas value was not, and order associated with typical student goals (e.g., achievement) compared with atypical goals (e.g., power). Output order is well suited to bring the study of accessibility to naturalistic studies of goals and goal pursuit.     

How a Group Goal May Reduce Social Matching in Group Performance: Shifts in Standards for Determining a Fair Contribution of Effort

Abstract

The authors investigated whether the presence of a specific group goal would reduce social matching (i.e., matching one's own performance to the performance expected from others) by serving as an alternative standard. As predicted, when there was no specific goal, the participants matched their own performance to the performance expected from other group members. When there was a specific group goal, the women no longer engaged in social matching, although that effect did not emerge among the men. Instead, the women's mean personal performance was close to the performance level representing an equal share of the group goal. Moreover, the participants' perceptions of a fair contribution mediated the performance of the men and the women, both in the presence and in the absence of a goal.     

Relations of Self-Esteem Concerns,Group Identification,and Self-Stereotyping to In-Group Favoritism

Abstract

In 2 studies, the author examined the effect of collective self-esteem (CSE; J. Crocker & R. Luhtanen, 1993) on people's willingness to display in-group favoritism. To test that self-esteem hypothesis, he measured public CSE, rather than private CSE, because the former parallels a threat to social identity, a state believed to motivate in-group favoritism. Furthermore, the author explored whether group identification and self-stereotyping moderated the effect of public CSE on in-group favoritism. The participants were 92 British and Dutch university employees. As expected, participants high in public CSE displayed more in-group favoritism than did those low in public CSE. Moreover, group identification and self-stereotyping appeared to moderate the effect of CSE.
