The impact of cross-training on team effectiveness.

The authors examined the role of cross-training in developing shared team-interaction mental models, coordination, and performance in a 2-experiment study using computer simulation methodology (for Experiment 1, N=45 teams; for Experiment 2, N=49 teams). Similar findings emerged across the 2 experiments. First, cross-training enhanced the development of shared team-interaction models. Second, coordination mediated the relationship between shared mental models and team performance. However, there was some inconsistency in the findings concerning the depth of cross-training necessary for improving shared mental models. Results are discussed in terms of the impact of different levels of cross-training on team effectiveness. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Interactions of team mental models and monitoring behaviors predict team performance in simulated anesthesia inductions.

In the present study, we investigated how two team mental model properties (similarity vs. accuracy) and two forms of monitoring behavior (team vs. systems) interacted to predict team performance in anesthesia. In particular, we were interested in whether the relationship between monitoring behavior and team performance was moderated by team mental model properties. Thirty-one two-person teams consisting of anesthesia resident and anesthesia nurse were videotaped during a simulated anesthesia induction of general anesthesia. Team mental models were assessed with a newly developed measurement tool based on the concept-mapping technique. Monitoring behavior was coded by two organizational psychologists using a structured observation system. Team performance was rated by two expert anesthetists using a performance-checklist. Moderated multiple regression analysis revealed that team mental model similarity moderated the relationship between team monitoring and performance; a higher level of team monitoring in the absence of a similar team mental model had a negative effect on performance. Furthermore, team mental model similarity and accuracy interacted to predict team performance. Our findings provide new insights on factors influencing the relationship between team processes and team performance in health care. When investigating the effectiveness of a specific team coordination behavior, team cognition has to be taken into account. This represents a necessary and compelling extension of the popular process-outcome relationship on which previous teamwork research in health care has focused. Moreover, the current study adds further external validity to the concept of team mental models by highlighting its usefulness in health care.

Measuring shared team mental models: A meta-analysis.

Although shared team mental models are believed to be important to team functioning, substantial interstudy differences in the manner in which mental models are operationalized has impeded progress in this area. We use meta-analysis to cumulate 23 independent studies that have empirically examined shared mental models (SMMs) in relation to team process and performance and test three aspects of measurement as potential moderators: elicitation method, structure representation, and representation of emergence. Results indicate the way in which SMMs are measured and represented at the team level of analysis reveal meaningful distinctions in observed relationships. Specifically, shared mental model operationalization impacts the observed relationship between SMMs and team process; importantly, only methods that model the structure or organization of knowledge are predictive of process. Conversely, while the magnitude of the relationship differed across measurement method, SMMs were positively related to team performance regardless of the manner of operationalization. In summary, knowledge structure is predictive of team process, and both knowledge content and structure are predictive of team performance.

Differentiating Knowledge in Teams: The Effect of Shared Declarative and Procedural Knowledge on Team Performance.

The relative effects of sharing mental models (typically defined as declarative knowledge structures) and sharing procedural knowledge on team process and performance were assessed. Forty-eight students completed a series of missions as two-person teams using a PC-based tank simulation. The results showed some support for earlier findings. Shared and accurate mental models of the task were related to team process, which was in turn related to team performance. In contrast, shared procedural knowledge was negatively related to team performance. Accurate procedural knowledge was positively related to team performance. Results are discussed in terms of the effect of sharing knowledge in teams on performance, and the implications for team training. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Team composition, cognition, and effectiveness: Examining mental model similarity and accuracy.

This study examined the relationships between team cognitive ability and personality composition in relation to the similarity (MM-similarity) and accuracy (MM-accuracy) of team task-focused mental models. The relationships between MM-accuracy and MM-similarity with multiple indicators of team effectiveness were also examined. Sixty-seven three-person teams performed a simulated search and capture task. Results indicate that the team mean-level of cognitive ability was positively related to both MM-accuracy and MM-similarity, and the team mean-level of team agreeableness was positively related to MM-similarity. In turn, MM-accuracy was positively related to perceived coordination processes and goal accomplishment, but not team viability. In contrast, MM-similarity was positively related to team viability, but not goal accomplishment or perceived coordination processes. Implications of the findings for understanding factors that facilitate the emergence of task-focused mental models in teams with a limited life span or during the early stages of team development are discussed, along with the implications of team mental models for team success.

Mental model metrics and team adaptability: A multi-facet multi-method examination.

This paper empirically examines the convergent, discriminant, and predictive validity of three team mental model measurement approaches. Specifically, this study measures the similarity (MM-similarity) and quality (MM-quality) facets of team strategy-focused mental models using structural networks, priority rankings, and importance ratings. The convergent and divergent relationships among the three mental model metrics are then examined via a multi-facet multi-method matrix. Finally, the relative utility of each metric for understanding the relationships between team mental models, team adaptability, and decision effectiveness are compared. The study was conducted in a laboratory setting, modeling 56 four-person decision-making teams. Results indicate little convergent and extensive discriminant validity across the three mental model metrics. In addition, only mental models measured using the structural networks metric were found to have predictive validity in relation to team adaptation and performance. The quality and similarity of team structural networks were found to have interactive effects in relation to adaptation such that mental model quality was most strongly related to adaptation for teams with low mental model similarity and unrelated to adaptation for teams with high similarity. In turn, adaptation was critical for team decision effectiveness. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Performance implications of leader briefings and team-interaction training for team adaptation to novel environments.

The authors examined how leader briefings and team-interaction training influence team members' knowledge structures concerning processes related to effective performance in both routine and novel environments. Two-hundred thirty-seven undergraduates from a large mid-Atlantic university formed 79 three-member tank platoon teams and participated in a low-fidelity tank simulation. Team-interaction training, leader briefings, and novelty of performance environment were manipulated. Findings indicated that both leader briefings and team-interaction training affected the development of mental models, which in turn positively influenced team communication processes and team performance. Mental models and communication processes predicted performance more strongly in novel than in routine environments. Implications for the role of team-interaction training, leader briefings, and mental models as mechanisms for team adaptation are discussed.

Relationships among team ability composition, team mental models, and team performance.

This study examined the relationship between the similarity and accuracy of team mental models and compared the extent to which each predicted team performance. The relationship between team ability composition and team mental models was also investigated. Eighty-three dyadic teams worked on a complex skill task in a 2-week training protocol. Results indicated that although similarity and accuracy of team mental models were significantly related, accuracy was a stronger predictor of team performance. In addition, team ability was more strongly related to the accuracy than to the similarity of team mental models and accuracy partially mediated the relationship between team ability and team performance, but similarity did not.

Evidence of mood linkage in work groups.

Two studies investigated whether people's moods are influenced by the collective mood of their work teammates over time. In the first study, 65 community nurses in 13 teams recorded their moods and hassles daily for 3 weeks. A pooled time-series analysis showed a significant association between the nurses' moods and the collective mood of their teammates, which did not depend on shared hassles. The association was greater for nurses who were older, were more committed to their team, perceived a better team climate, or experienced fewer hassles with teammates. In Study 2, a team of 9 accountants rated their own moods and the moods of their teammates 3 times a day for 4 weeks using pocket computers. The accountants' moods and their judgments of their teammates' moods were significantly associated with the collective mood of their teammates. The findings suggest that people's mood at work can become linked to the mood of their teammates. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Developing a theory of the strategic core of teams: A role composition model of team performance.

Although numerous models of team performance have been articulated over the past 20 years, these models have primarily focused on the individual attribute approach to team composition. The authors utilized a role composition approach, which investigates how the characteristics of a set of role holders impact team effectiveness, to develop a theory of the strategic core of teams. Their theory suggests that certain team roles are most important for team performance and that the characteristics of the role holders in the "core" of the team are more important for overall team performance. This theory was tested in 778 teams drawn from 29 years of major league baseball (1974'-2002). Results demonstrate that although high levels of experience and job-related skill are important predictors of team performance, the relationships between these constructs and team performance are significantly stronger when the characteristics are possessed by core role holders (as opposed to non-core role holders). Further, teams that invest more of their financial resources in these core roles are able to leverage such investments into significantly improved performance. These results have implications for team composition models, as they suggest a new method for considering individual contributions to a team's success that shifts the focus onto core roles.

Guidelines and feedback in information exchange: The impact of behavioral anchors and descriptive norms in a social dilemma.

Exchanging information through a shared database is a social dilemma. Each member of a work group saves costs by not contributing any information and by using the database only to retrieve information that was contributed by others. But if all people act according to this strategy, then the database is empty and useless for each group member. This article describes how standards influence people's behavior in this information-exchange dilemma. Based on assumptions about anchoring processes and processes of social comparison, the authors expect guidelines (as anchors) and feedback about others' behavior (as social standards) to influence people's information exchange. The first experiment indicates that arbitrary guidelines serve as behavioral anchors and influence people's contribution behavior-but only if the guidelines are made salient enough. The second experiment shows that bogus feedback about teammates' high or low contribution rates provoke the participants to conform to the behavior of the others.

The cognitive underpinnings of effective teamwork: A meta-analysis.

Major theories of team effectiveness position emergent collective cognitive processes as central drivers of team performance. We meta-analytically cumulated 231 correlations culled from 65 independent studies of team cognition and its relations to teamwork processes, motivational states, and performance outcomes. We examined both broad relationships among cognition, behavior, motivation, and performance, as well as 3 underpinnings of team cognition as potential moderators of these relationships. Findings reveal there is indeed a cognitive foundation to teamwork; team cognition has strong positive relationships to team behavioral process, motivational states, and team performance. Meta-analytic regressions further indicate that team cognition explains significant incremental variance in team performance after the effects of behavioral and motivational dynamics have been controlled. The nature of emergence, form of cognition, and content of cognition moderate relationships among cognition, process, and performance, as do task interdependence and team type. Taken together, these findings not only cumulate extant research on team cognition but also provide a new interpretation of the impact of underlying dimensions of cognition as a way to frame and extend future research.

Vertical versus shared leadership as predictors of the effectiveness of change management teams: An examination of aversive, directive, transactional, transformational, and empowering leader behaviors.

This study investigated vertical versus shared leadership as predictors of the effectiveness of 71 change management teams. Vertical leadership stems from an appointed or formal leader of a team, whereas shared leadership (C. L. Pearce, 1997; C. L. Pearce & J. A. Conger, in press; C. L. Pearce & H. P. Sims, 2000) is a group process in which leadership is distributed among, and stems from, team members. Team effectiveness was measured approximately 6 months after the assessment of leadership and was also measured from the viewpoints of managers, internal customers, and team members. Using multiple regression, the authors found both vertical and shared leadership to be significantly related to team effectiveness (p     

Sacrifice, cohesion, and conformity to norms in sport teams.

The authors investigated the relationship between group members' voluntarily initiating an action or giving up prerogative or privilege for the sake of another person or persons without regard to reciprocity and members' conformity to group norms. The members of 13 high-level cricket teams described the extent to which they and their teammates regularly made personal sacrifices for the good of their teams. They also described their group's cohesiveness and their conformity to such group norms as "support each other" and "stick to the training schedule." The analyses supported the conclusion that perceptions of individual sacrifice and teammates' sacrifice contribute to group cohesion and, in turn, cohesion contributes to perceptions of teammates' conformity to group norms. Beyond these general findings, a number of aspects related to specific results are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Building the infrastructure: The effects of role identification behaviors on team cognition development and performance.

The primary purpose of this study was to extend theory and research regarding the emergence of mental models and transactive memory in teams. Utilizing Kozlowski, Gully, Nason, and Smith’s (1999) model of team compilation, we examined the effect of role identification behaviors and posited that such behaviors represent the initial building blocks of team cognition during the role compilation phase of team development. We then hypothesized that team mental models and transactive memory would convey the effects of these behaviors onto team performance in the team compilation phase of development. Results from 60 teams working on a command-and-control simulation supported our hypotheses. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Schools as team-based organizations: A structure-process-outcomes approach.

The present study addressed the issue of teams in schools and the ways in which they contribute to school effectiveness. Specifically, the present research suggested an input (frequency of meetings and functional heterogeneity)-process (interaction processes of exchanging information, learning, motivating, and negotiating)-outcome (team performance and innovation) model for predicting school effectiveness. Two hundred twenty-four school teams (including team coordinators, team members, and school principals) were surveyed. The results indicated that, regarding team innovation, frequency of meetings and functional heterogeneity were positively associated with the 4 interaction processes, which in turn fostered team innovation. However, regarding team performance, the results indicated that only frequency of meetings was positively associated with the interaction process of exchanging information, which in turn enhanced team performance. The findings serve to draw important theoretical and practical conclusions as to the best ways to structure schools and to improve their interaction processes for the enhancement of team performance and team innovation.

Cooperative outcome interdependence, task reflexivity, and team effectiveness: A motivated information processing perspective.

A motivated information processing perspective (C. K. W. De Dreu & P. J. D. Carnevale, 2003; see also V. B. Hinsz, R. S. Tindale, & D. A. Vollrath, 1997) was used to predict that perceived cooperative outcome interdependence interacts with team-level reflexivity to predict information sharing, learning, and team effectiveness. A cross-sectional field study involving management and cross-functional teams (N = 46) performing nonroutine, complex tasks corroborated predictions: The more team members perceived cooperative outcome interdependence, the better they shared information, the more they learned and the more effective they were, especially when task reflexivity was high. When task reflexivity was low, no significant relationship was found between cooperative outcome interdependence and team processes and performance. The author concludes that the motivated information processing perspective is valid outside the confines of the laboratory and can be extended toward teamwork in organizations.

Embracing transformational leadership: Team values and the impact of leader behavior on team performance.

The authors investigated the relationship between transformational leadership behavior and group performance in 218 financial services teams that were branches of a bank in Hong Kong and the United States. Transformational leadership influenced team performance through the mediating effect of team potency. The effect of transformational leadership on team potency was moderated by team power distance and team collectivism, such that higher power distance teams and more collectivistic teams exhibited stronger positive effects of transformational leadership on team potency. The model was supported by data in both Hong Kong and the United States, which suggests a convergence in how teams function in the East and West and highlights the importance of team values.

The evolution of hexamerins and the phylogeny of insects

The impact of group discussion on the decision-making effectiveness of medical teams was examined. Three-person teams of physicians diagnosed 2 hypothetical medical cases. Some of the information about each case was given to all team members prior to discussion (shared information), whereas the rest was divided among them (unshared information). Compared with unshared information, shared information was more likely to be pooled during discussion and was pooled earlier. In addition, team leaders were consistently more likely than other members to ask questions and to repeat shared information and, over time, also became more likely than others to repeat unshared information. Finally, pooling unshared (but not shared) information improved the overall accuracy of the team diagnoses, whereas repeating both shared and unshared information affected bias (but not accuracy) in the diagnoses.
