Reflections on shared cognition

The purpose of this paper is to highlight several fundamental questions that remain regarding shared cognition: (1) What must be ‘shared’? (2) What does ‘shared’ mean? (3) How should ‘shared’ be measured? and (4) What outcomes do we expect shared cognition to affect? A general and integrative description of these questions is provided. In addition, the value of shared cognition is discussed along with recommendations for future research. Copyright © 2001 John Wiley & Sons, Ltd.
