Transactive memory is a psychological speculation first proposed by Daniel Wegner in 1985 as a response to earlier theories of "group thoughts" comparable to groupthink. A transactive memory system is a mechanism by means of which groups collectively encode, retailer, and retrieve knowledge. A transactive memory system includes memory stored in each particular person, the interactions between memory within the individuals, as well because the processes that update this memory. Transactive memory, then, is the shared store of data. In line with Wegner, a transactive Memory Wave Program system consists of the knowledge saved in every particular person's memory mixed with metamemory containing info relating to the different teammate's domains of experience. The transactive memory system works similarly to exterior memory, the place other members of the group are the exterior memory assist. Simply as a person's metamemory allows them to be aware of what information is on the market for retrieval, so does the transactive memory system provide teammates with info regarding the information they've access to throughout the group.

Group members learn who data experts are and how one can access expertise by way of communicative processes. In this way, Memory Wave Program a transactive memory system can present the group members with more and higher information than any individual might entry on their very own. This concept proposed that when two individuals spend a number of time round one another and work together, they create a shared store of knowledge between the members. In essence, one member of the couple could store info within their partner after which recall that info by asking their accomplice about it. This idea was different and distinctive from different descriptions of socially distributed cognition in that it describes a situation the place individuals hold completely different knowledge in comparison with shared info, and members of the group interact in transactions to help in recall of the saved information. In a latest review, Ren and Argote described transactive memory as existing of each a structural component (the linkages of particular person memory to the collective) and transactive processes that make the transactive memory dynamic.

Wegner first proposed these three processes which occur in groups that result in the formation and reification of transactive memory: encoding, storage, and retrieval described more below. The reason for these findings are that couples know the way greatest to remind one another of the information they have, and that couples have an excellent conception of the other's information and will due to this fact avoid memorizing words inside their associate's domain. Strangers do not have entry to this identical shared info which ends up in poorer efficiency in these kinds of tasks. Transactive memory was additional extended by Diane Liang and colleagues into the realm of work groups. On this work, the development of transactive memory was conceived of as a manner to enhance group's efficiency when participating in interdependent tasks. After this extension, transactive memory turned extra prolific in organizational behavior amongst different disciplines. Just like human memory, the development of a transactive memory system entails three phases: encoding, storage and retrieval. These processes are transactive, which means that they're up to date as members change information with each other.

Within the encoding stage, the teammates gain info on the opposite team members' domains of information and categorize it by ascribing every information area to the corresponding crew member. Generally, this acquaintance can emerge by way of "who did what" or "who knows what" conversation, or even through direct instruction similar to by telling a teammate to recollect certain data. There could even be dialogue and negotiation of where and in what type to store information in the group. The encoding process is very important in the development of transactive memory. Encoding occurs by means of interaction between teammates: via sharing information and seeking info from different staff members, teammates be taught the experience of every workforce member as a first important step towards specialization. These specialists then are answerable for continuing to encode new and relevant information in their domains of data. Within the storage stage, the relevant info is stored within the possession of the workforce member, or members, with the corresponding expertise; once the experts have been identified, new data is transmitted on to these staff members.

This improves the learning course of and reduces the load on the memory of individual teammates. With transactive memory storage, a workforce member only has to remember the information of their domain of expertise, while they solely have to remember what the other members' domains of experience are reasonably than storing all the data within the transactive memory. Information could also be also misplaced or modified throughout storage for transitive memory, as is the case in individual memory. These modifications, however, could also be even more fast and impactful than in particular person memory as a result of the information is scattered and saved with a number of members in the group, making the information more readily changed with misinformation. Through the retrieval stage, a bunch member uses the developed transactive memory to determine a group member that specializes within the required data space and then turns to that member to realize the knowledge. If the inquiring member has not encoded of their particular person metamemory who specializes within the information, retrieval can be initiated by asking different members in the storage system for who the expert who makes a speciality of the information they wish to retrieve is, then connecting with that knowledgeable after a collection of consultations.
