Relations entre réflexivité d’équipe,mémoire transactive et efficacité interventionnelle perçue chez les policiers-opérateurs du RAID

The objective of this study is to examine the influence of explicit (team reflexivity) and implicit (transactive memory) coordination processes on the perceived interventional effectiveness of specialized elite units (RAID) of the French national police. We test the hypothesis that transactive memory is a mediating process in the relationship between team reflexivity and perceived effectiveness. One hundred and three police-officers representing the seven French police special units replied to a questionnaire. The results show that perceived effectiveness is positively related to task reflexivity and transactive memory. The relationship between task reflexivity and perceived effectiveness is mediated by the integrated component of transactive memory (bootSE = 0.05, 95% BCa CI [0.004, 0.19]). The theoretical and practical implications are discussed with regard to the development of debriefing methods and teamwork training for the development of shared mental models.     

Coping with challenge and hindrance stressors in teams: Behavioral,cognitive, and affective outcomes

The purpose of this study was to utilize the challenge–hindrance framework to examine the discrete and combined effects of different environmental stressors on behavioral, cognitive, and affective outcomes at the team level. Results from 83 teams working on a command and control simulation indicated that the introduction of a challenge stressor positively affected team performance and transactive memory. The introduction of a hindrance stressor negatively affected team performance and transactive memory and positively affected psychological withdrawal. When the hindrance stressor was combined with the challenge stressor, teams exhibited the lowest levels of performance and transactive memory, and the highest levels of psychological withdrawal. These effects were due to the adoption of specific coping strategies by team members. Implications are discussed, as well as limitations and directions for future research.     

First,get your feet wet: The effects of learning from direct and indirect experience on team creativity

How does prior experience influence team creativity? We address this question by examining the effects of task experience acquired directly and task experience acquired vicariously from others on team creativity in a product-development task. Across three laboratory studies, we find that direct task experience leads to higher levels of team creativity and more divergent products than indirect task experience. Moreover, our results show that the difference in team creativity between direct and indirect task experience persists over time. Finally, our findings demonstrate that transactive memory systems fully mediate the effect of direct task experience on team creativity. Teams who acquired task experience directly are more creative because they develop better transactive memory systems than teams who acquired experience vicariously. We discuss how our findings contribute to understanding the effects of prior experience on team creativity, and the role of transactive memory systems in creative tasks.     

A temporal common ground for learning: The moderating effect of shared mental models on the relation between team learning behaviours and performance improvement

In this longitudinal study, we integrated a team process and a learning curve perspective on team learning and empirically analysed whether team learning processes lead to performance improvement. In addition, we tested whether this relation is moderated by the similarity of team members’ task, team, and temporal mental models. We tested our model on a sample of 67 teams (314 individuals) competing in a management simulation over five consecutive time periods, using random coefficient modelling (RCM). Our findings suggest that team learning behaviours do not have a direct effect on the team learning curve, but temporal and task mental models are crucial for the translation of team learning behaviours into performance improvement. We found that when teams have similar task and temporal mental models, engaging in team learning processes is beneficial, whereas, when teams have dissimilar task and temporal mental models, it is detrimental to performance improvement. We did not find a significant effect for the moderating role of team mental model similarity. Our study emphasizes the importance of integrating different perspectives on team learning and provides support for the role of team cognition as a catalyst for team learning.     

Reaping what they sow: Benefits of remembering together in intimate couples

Recent research suggests that remembering with a long-term partner may scaffold successful memory. To test whether collaboration reduces the episodic deficit shown by older adults, we created a social version of Addis, Musicaro, Pan, and Schacter's (2010) episodic memory paradigm. As predicted, in Experiment 1 20 long-married, older adult couples generated more “internal” – on topic, episodic – details when they remembered together versus alone, but the same amount of “external” – off-topic, semantic – details. In Experiment 2 this memory benefit did not extend to 20 young adult couples who generated high levels of internal details together or alone. Notably, however, young adults’ self-reported relationship intimacy was related to their episodic recall across conditions. We discuss these findings in terms of possible benefits of collaboration in the face of ageing and cognitive decline as well as the development over time of “transactive memory systems” in intimate relationships.

Collective interviewing: A transactive memory approach towards identifying signs of truthfulness

Group interviewing has been neglected in the deception literature, yet it coincides with recent collective memory research. The present experiment applied the transactive memory theory to a collective interviewing situation and explored whether signs of truthfulness emerged through measuring joint memory recall. Truth-tellers were real couples who had been in a relationship for at least one year and cohabiting. Lying pairs were friends who pretended to be in a relationship for at least one year and cohabiting. All couples were interviewed in their pairs about their ‘real’ or ‘fictitious’ relationships. It was found that truth-telling pairs posed questions to one another, provided cues to one another, handed over remembering responsibility, and finished each others’ sentences significantly more than lying pairs, supporting the idea that real couples have a transactive memory system, unlike pretending couples. Implications for a collective interview approach that considers memory within deception detection are discussed.     

团队断裂带对团队绩效的影响：团队交互记忆系统的作用

Gender stereotypes and assumptions about expertise in transactive memory

This experiment investigated how people use gender stereotypes to infer the relative knowledge of interdependent others, and how those assumptions can affect the division of knowledge responsibilities in transactive memory systems. Participants indicated their expertise relative to the average male and female undergraduate student on six knowledge categories. Two of these were consistent with female stereotypes (soap operas and cosmetics), two were consistent with male stereotypes (sports and cars), and two were neutral (geography and history). Everyone then worked on a collective memorization task with an assumed partner. The design was a 2 × 2 factorial, with the participants’ gender and their assumed partners’ gender (same or different as the participant’s) as factors. The results showed that both male and female participants shared similar gender stereotypes across knowledge domains. Participants with opposite-sex partners were more likely to assign categories based on gender stereotypes than were participants with same-sex partners. As a result, participants with opposite-sex partners learned more information in categories consistent with those stereotypes. These findings suggest that transactive memory systems may perpetuate gender stereotypes.

Potential Benefits of Communication in Transactive Memory Systems

Transactive memory theory views communication as a valuable (but not perfect) tool for learning, storing, and retrieving information from other people. In this essay, we review research on transactive memory systems and elaborate on the role of communication in the development and use of such systems. In contrast to Pavitt (2003), we believe that communication can, under some conditions, facilitate the development of an effective group memory system.     

Composition and transactive memory systems

A recurrent theme in research on socially distributed cognition is to establish the claim that the cognitive phenomenon of transactive memory is grounded in a specific mode of organization: mechanistic compositional organization. My topic is the confluence of transactive remembering or transactive memory systems (TMSs) and mechanistic compositional organization. In relation to this confluence, the paper scrutinizes the claim that the kind of organization grounding TMSs and/or tokens of transactive remembering takes the specific form of mechanistic compositional organization – at least as the latter is usually construed. It is argued (i) that the usual account of mechanistic compositional organization is based on a synchronic composition function, and (ii) that the organization of TMSs and/or transactive remembering is not well understood by way of synchronic composition. The positive account pursued is that TMSs and/or transactive remembering are better understood as grounded in a diachronic composition function.     

Assessing team performance: Moderating roles of transactive memory,hypercompetition, and emotional regulation

This study proposes a model based on transactive memory theory to analyze team performance. In the proposed model, team performance is influenced by hypercompetition and emotional regulation directly and indirectly via the mediation of transactive memory and knowledge sharing. According to the model, the direct effect of knowledge sharing on team performance is moderated by both hypercompetition and emotional regulation. Empirical testing of this model, using team personnel in banking, insurance, and financing firms, confirmed the applicability of the transactive memory theory among these service firms’ work teams. Managerial implications and research limitations are discussed.     

Group cognition,membership change,and performance: Investigating the benefits and detriments of collective knowledge

This study analyzes the effects of group membership change on group cognition and performance to determine how groups can simultaneously leverage oldtimers’ collective knowledge and a newcomer’s expertise. Our analysis focuses specifically on the interrelated effects of the two components of a transactive memory system (TMS)—TMS structure and TMS processes—to explain the cognitive mechanisms through which membership change affects group performance. Results from a laboratory study show that groups that experience partial membership change tend to rely on the TMS structure that oldtimers developed in their original group, and that doing so is ultimately detrimental to performance because it creates inefficient TMS processes. Results from a supplemental study indicate that these TMS process inefficiencies can be avoided when oldtimers are instructed to reflect upon their collective knowledge prior to task execution. We discuss the implications for managing group cognition in organizations where membership change is prevalent.     

The Benefits of Stepping Into Others' Shoes: Perspective Taking Strengthens Transactive Memory

Perspective taking is an important requirement for effective communication. Teams working on knowledge-intensive tasks should benefit particularly. In a laboratory study, we examined whether perspective taking (vs. egocentrism) facilitated transactive memory when team members' knowledge was either different or similar. Perspective taking led teams to form more accurate transactive memory and agree more regarding each other's knowledge assessments. Corresponding effects were found when knowledge was similar. However, no interaction emerged. Our study shows that perspective taking is a cognitive state that can be induced with a short intervention and that can positively influence team-level outcomes such as transactive memory.     

Exploring memory in infancy: deferred imitation and the development of declarative memory

Imitation is an important means by which infants learn new behaviours. When infants do not have the opportunity to immediately reproduce observed actions, they may form a memory representation of the event which can guide their behaviour when a similar situation is encountered again. Imitation procedures can, therefore, provide insight into infant memory. The deferred imitation paradigm requires a modelled action to be reproduced following a delay, without prior motor practice. As such, deferred imitation procedures have been proposed to tap declarative memory abilities in non‐verbal populations such as infants. Contrary to the popular belief that infants form sparse or ill‐defined memories, deferred imitation research reveals that infants store and retrieve highly detailed memory representations. The specificity of detail encoded into the representation can, however, cause memory retrieval to fail at young ages. Developing the ability to identify event components which are central (the target stimulus) versus details which are peripheral (the exact context in which learning occurred) is therefore an important aspect of memory development. Using deferred imitation procedures to study the transition from constrained to flexible memory representations can thus facilitate our understanding of the development of declarative memory during the infancy period.

Transactive memory in organizational groups: the effects of content, consensus, specialization, and accuracy on group performance

Previous research on transactive memory has found a positive relationship between transactive memory system development and group performance in single project laboratory and ad hoc groups. Closely related research on shared mental models and expertise recognition supports these findings. In this study, the author examined the relationship between transactive memory systems and performance in mature, continuing groups. A group's transactive memory system, measured as a combination of knowledge stock, knowledge specialization, transactive memory consensus, and transactive memory accuracy, is positively related to group goal performance, external group evaluations, and internal group evaluations. The positive relationship with group performance was found to hold for both task and external relationship transactive memory systems.     

Transactive memory in decision-making teams: implications for team effectiveness

The transactive memory system (TMS) construct is one of the most extended theoretical approaches to understand the role of cognitive processes at group level in the effectiveness of work teams. This study examined the relationships among TMS, performance, satisfaction and functional communication in decision-making teams. 40 four-person teams were asked to suppose they were expert consulting teams advising a fictitious organization on how to solve a problem with their employees. Results showed a mediating effect of TMS on the relationships between functional communication, perceived team performance and satisfaction. Contrary to our expectations, TMSs were not related to performance as evaluated by external raters. These findings suggest the importance of team communication in the formation of TMSs, as well as their implications for the effectiveness of decision-making teams.     

Declarative working memory: A bio-inspired cognitive architecture proposal

Memory is considered one of the most important functions since it allows us to code, store and retrieve knowledge. These qualities make it an indispensable function for a virtual creature. In general, memory can be classified based on the durability of the stored data in working memory and long-term memory. Working memory refers to the capacity to maintain temporarily a limited amount of information in mind, which can then be used to support various abilities, including learning, reasoning, planning and decision-making. Unlike short-term memory, working memory is not only a storage site, but it is also a framework of interacting processes that involve the temporary storage and manipulation of information in the service of performing complex cognitive activities. Declarative memory is a type of long-term memory related with the storage of facts and events. This research focuses on the development of a cognitive architecture for the type of working memory that maintains and manipulates declarative information. The construction of the model was grounded in theoretical evidence taken from cognitive sciences such as neuroscience and psychology, which gave us the components and their processes. The model was evaluated through a case study that covers the encoding, storing, and retrieval stages. Our hypothesis is that a virtual creature endowed with our working memory model will provide faster access to the information needed for the ongoing task. Therefore, it improves the planning and decision-making processes.     

Diversity in goal orientation, team reflexivity, and team performance

Although recent research highlights the role of team member goal orientation in team functioning, research has neglected the effects of diversity in goal orientation. In a laboratory study with groups working on a problem-solving task, we show that diversity in learning and performance orientation are related to decreased group performance. Moreover, we find that the effect of diversity in learning orientation is mediated by group information elaboration and the effect of diversity in performance orientation by group efficiency. In addition, we demonstrate that team reflexivity can counteract the negative effects of diversity in goal orientation. These results suggest that models of goal orientation in groups should incorporate the effects of diversity in goal orientation.
