The role of schizotypy and creativity in a group problem-solving task

The well-studied link between psychotic traits and creativity is a subject of much debate. The present study investigated the extent to which schizotypic personality traits – as measured by O-LIFE (Oxford–Liverpool Inventory of Feelings and Experiences) – equip healthy individuals to engage as groups in everyday tasks. From a sample of 69 students, eight groups of four participants – comprised of high, medium, or low-schizotypy individuals – were assembled to work as a team to complete a creative problem-solving task. Predictably, high scorers on the O-LIFE formulated a greater number of strategies to solve the task, indicative of creative divergent thinking. However, for task success (as measured by time taken to complete the problem) an inverted U shaped pattern emerged, whereby high and low-schizotypy groups were consistently faster than medium schizotypy groups. Intriguing data emerged concerning leadership within the groups, and other tangential findings relating to anxiety, competition and motivation were explored. These findings challenge the traditional cliché that psychotic personality traits are linearly related to creative performance, and suggest that the nature of the problem determines which thinking styles are optimally equipped to solve it.     

A functional perspective on group memberships: Differential need fulfillment in a group typology

The social motivation functions of intimacy, task, and social category groups were investigated. In two studies, participants were asked to consider the extent to which their group memberships fulfilled several needs. A factor analysis confirmed that the needs comprised three factors: affiliation, achievement, and identity. Intimacy groups were associated with affiliation needs, task groups were associated with achievement needs, and social category groups were associated with identity. A study using implicit measures reinforced those results, revealing the presence of the same implicit associations between group types and need fulfillments. A final study manipulated participants’ need state through a priming procedure. Priming a specific need (affiliation, achievement, and identity) led to an increased accessibility of the group type that was best suited to meet that need (intimacy, task, social category, respectively). Results help clarify the functional aspects of groups and have implications for the perception and organization of group-level information.     

The psychological costs of knowledge specialization in groups: Unique expertise leaves you out of the loop

Knowledge specialization, such as that present in cross-functional teams, produces both positive and negative outcomes. Our research investigated how unique expertise can lead to feelings of ostracism in the form of being out of the loop. Compared to group members with shared expertise, members with unique expertise felt out of the loop and experienced decreased fulfillment of fundamental needs, particularly when their expertise was to be given less weight in the group’s decision. Possessing unique expertise did not inhibit leadership emergence, even when that expertise should not have been used in the decision-making process. So, although knowledge specialization can have positive consequences for teams and task performance, it also has some negative psychological consequences that need to be understood.     

The rhythm of joint action: Synchrony promotes cooperative ability

Although evidence has suggested that coordinated action enhances rapport and fosters cooperation, the possibility that it might also influence the ability to pursue joint goals has yet to be demonstrated. We show that rocking in synchrony enhanced individuals’ perceptual sensitivity to the motion of other entities and thereby increased their success in a subsequent joint-action task that required the ability to dynamically detect and respond appropriately to a partner’s movements. These findings support the view that in addition to fostering social cohesion, synchrony hones the abilities that allow individuals to functionally direct their cooperative motives.     

Being distinctive versus being conspicuous: The effects of numeric status and sex-stereotyped tasks on individual performance in groups

Being in the numeric minority (e.g., being a solo woman in a group of men) influences how well a person performs within a work group. But being the solo member is only one way in which people can be atypical in a group; a person can also represent a social or demographic category that has not typically been associated with the task that the group is working on. Using a design with four categories of group composition (minority, balanced, majority, homogeneous) and two categories of tasks (sex-typical, sex-atypical) we found that the sex composition of the group interacted with the sex typicality of the task to influence both positive deferrals by group members and individual performance in groups. But, rather than consistently reducing performance as prior research has suggested, being numerically atypical enhanced individual performance when the task was typical for that person’s sex. Further, positive deferrals mediated between the interaction of numeric composition and task typicality in influencing individual performance suggesting that both majority group members and the solo member affect one another’s performance in groups. We conclude by discussing why understanding the interplay between these two sources of stereotyping, numeric composition and task typicality, is important for understanding the social nature of individual performance in groups.     

Changes in Families’ Caregiving Experiences through Involvement as Participants then Facilitators in a Family Peer‐Education Program for Mental Disorders in Japan

A family peer‐education program for mental disorders was developed in Japan, similar to existing programs in the United States and Hong Kong. Families that serve as facilitators in such programs may enhance their caregiving processes and, thereby, their well‐being. This study's aim was to describe how families’ caregiving experiences change, beginning with the onset of a family member's mental illness, through their involvement in a family group or peer‐education program as participants then facilitators. Thus, this study was conducted in a family peer‐education program for mental disorders in Japan. Group interviews were conducted with 27 facilitators from seven program sites about their experiences before, during, and after becoming facilitators. Interview data were coded and categorized into five stages of caregiving processes: (1) withdrawing and suppressing negative experiences with difficulty and regret; (2) finding comfort through being listened to about negative experiences; (3) supporting participants’ sharing as facilitators; (4) understanding and affirming oneself through repeated sharing of experiences; and (5) finding value and social roles in one's experiences. The third, fourth, and fifth stages were experienced by the facilitators. The value that the facilitators placed on their caregiving experiences changed from negative to positive, which participants regarded as helpful and supportive. We conclude that serving as facilitators may improve families’ caregiving processes.

An enquiry concerning the principles of cultural norms and values: The impact of uncertainty and mortality salience on reactions to violations and bolstering of cultural worldviews

This enquiry concerning the principles of cultural norms and values focuses on the impact of mortality and uncertainty salience on people’s reactions to events that violate or bolster their cultural norms and values. Five experiments show that both mortality and uncertainty salience influence people’s reactions to violations and bolstering of their cultural worldviews, yielding evidence for both terror and uncertainty management theories. Interestingly, the five experiments consistently reveal that uncertainty salience has a bigger impact on people’s reactions than mortality salience, suggesting that the former may be a more important antecedent of reactions to norms and values than the latter. Findings further suggest that uncertainty salience did not instigate death-thoughts whereas reactions to norms and values were stronger among mortality salient participants who thought of uncertainty as a result of the mortality salience manipulation than mortality salient participants who did not think of uncertainty following this manipulation. Implications are discussed.     

Affective expressions in groups and inferences about members' relational well-being: The effects of socially engaging and disengaging emotions

Our findings draw attention to the interpersonal communication function of a relatively unexplored dimension of emotions—the level of social engagement versus disengagement. In four experiments, regardless of valence and target group gender, observers infer greater relational well-being (more cohesiveness and less conflict) between group members from socially engaging (sadness and appreciation) versus disengaging (anger and pride) emotion expressions. Supporting our argument that social (dis)engagement is a critical dimension communicated by these emotions, we demonstrate (1) that inferences about group members' self-interest mediate the effect of socially engaging emotions on cohesiveness and (2) that the influence of socially disengaging emotion expressions on inferences of conflict is attenuated when groups have collectivistic norms (i.e., members value a high level of social engagement). Furthermore, we show an important downstream consequence of these inferences of relational well-being: Groups that seem less cohesive because of their members' proud (versus appreciative) expressions are also expected to have worse task performance.     

Testosterone–status mismatch lowers collective efficacy in groups: Evidence from a slope-as-predictor multilevel structural equation model

The study of the biological underpinnings of behavior is in its nascent stages in the field of management. We study how the hormone testosterone (T) is related to status and collective efficacy in a group. We assessed salivary testosterone of 579 individuals in 92 teams. We find that T does not predict status within the group. We also tested the effects of a mismatch between T and status in the group on the collective efficacy of the group. Using a novel slope-as-predictor multilevel structural equation model, we find that the greater the mismatch between T and status in the group (i.e., the more negative the within-group correlation among T and status), the lower is the collective efficacy of the group. We discuss the implications of our findings for the study of the biological underpinnings of group behavior in organizations.
