In their reaction to cognitivism, researchers have come to shift the f
ocus of study from cognition to action, and to emphasize the essential
ly situated nature of activity. In this introductory article, we exami
ne examples of this move toward ''situating action'' within and beyond
psychology, making special reference to issues raised by Suchman (198
7): the inseparability of action and context; the relation between the
social and material conditions of action; the need to theorize the ''
higher psychological functions'' in relation to situated action; and t
he tension between the emphasis on situation and the scientific ideal
of abstraction.
