Distributed knowledge and transactive processes in decision-making groups.
ABSTRACT Presents a model that examines the relations between group members' individual knowledge, communication processes, and group decisions. The model proposes that communication processes involved in effective information exchange change depending on the degree to which information needed for an effective group decision is known by all, some, one, or no group members, and on the degree to which members have a shared understanding about who knows what. The model is presented in the form of 9 propositions about 4 processes; comparing individual knowledge, establishing expertise, searching for needed information, and communicating information. Two studies comparing retrieval processes in memory systems are presented. Ss from both studies were heterosexual dating couples who had been dating at least 6 mo and were college students. Ss completed (either 2 or 3 times) a general knowledge task individually or with their partner or strangers. The data suggest that even strangers have a transactive memory system, which improves with task repetition. Strangers began developing their transactive memory system by explicitly establishing relative expertise as indicated by their higher frequency of expertise assertions relative to intimate couples. Knowledge test questions are appended. (PsycINFO Database Record (c) 2012 APA, all rights reserved)

ABSTRACT: Transactive memory system (TMS) theory explains how expertise is recognized and coordinated in teams. Extending current TMS research from a group information-processing perspective, our article presents a theoretical model that considers TMS development from a social identity perspective. We discuss how two features of communication (quantity and quality) important to TMS development are linked to TMS through the group identification mechanism of a shared common team identity. Informed by social identity theory, we also differentiate between intragroup and intergroup contexts and outline how, in multidisciplinary teams, professional identification and perceived equality of status among professional subgroups have a role to play in TMS development. We provide a theoretical discussion of future research directions aimed at testing and extending our model.Group & Organization Management 01/2012; 37(2):204-240. · 2.43 Impact Factor

ABSTRACT: This study focuses on the initial conditions of work teams and the impacts of these conditions on the development of teams’ transactive memory (TM) systems through computational modeling. TM theory describes the conditions under which team members retrieve and allocate information to accomplish collective tasks. Previous research has shown evidence for teams developing TM systems over time, but field research does not allow for the extensive manipulation of initial conditions a team might face when working together; conversely, this experimental research allowed for such manipulations without negatively impacting the ongoing productivity of organizations. Initial knowledge, initial accuracy of expertise recognition, and network size are explored as predictor variables on the development of a TM system as mediated through communication. System development is measured by the degree to which team members accurately perceive other members’ expertise and the extent to which the system has differentiated its stored knowledge. This study includes theoretically derived propositions tested through a path analysis of computationally generated data. The analysis validates the five propositions and is consistent with the developmental mechanisms of TM theory. Three additional paths proved to be significant and directly connect the initial conditions with the developmental indicators at the end state model.Communication Theory 01/2006; 16(2):223-250. · 1.48 Impact Factor
