“…Our main argument is that understanding team cognition as it occurs in real-world work settings requires an expanded view where cognition is seen as distributed and context dependent in a social environment in which artifacts often support cognitive functions ( Suchman, 1987 , 2007 ; Hutchins, 1995a ; Clancey, 1997 ; Hollnagel, 2002 ). Specifically, we advance the notion that artifacts support cognition by enabling the transition and development of internalized knowledge held by team members to externalized knowledge held at the team-level ( Fiore et al, 2010b ; Rentsch et al, 2010 , 2014 ). We draw from a diverse body of research and theory to emphasize that the functions of cognition can, and must be, viewed as sometimes occurring, not just “in” the head, but also “outside the head”; that is, viewing cognition in a broader context as distributed across the boundaries of brains, bodies, and environment ( Fiore, 2012 ; Cooke et al, 2013 ; Gorman, 2014 ).…”
