Final answer:
The group task role responsible for note-taking and maintaining 'group memory' is the scribe or recorder, who documents all pertinent discussion points and decisions.
Step-by-step explanation:
The group task role that is responsible for writing down the product of discussion and serving as the 'group memory' is typically known as the scribe or recorder. The person in this role takes detailed notes during meetings or group activities, ensuring that all important points, decisions, and actions are documented for future reference. This is essential for maintaining group continuity, tracking progress, and providing a reliable account of what has been discussed and agreed upon.
The role of the scribe is critical in collaborative settings, as it facilitates effective communication and helps to avoid misunderstandings. It allows the group to focus on discussion without worrying about remembering every detail. The notes taken by the scribe are often shared with all group members and may be referred back to in future meetings or when drafting reports or summaries of the group's work.
