a collaborative knowledge base characterizing the state of current thought in Cognitive Science.
active maintenance and flexible updating of goal/task relevant information (items, goals, strategies, etc.) in a form that resists interference but has limited capacity. These representations may involve flexible binding of representations, may be characterized by the absence of external support for the internally maintained representations, and are frequently temporary due to ongoing interference
