The articles which follow report independent research that originated in a collaborative group now organized as the Laboratory for Cognitive Studies of Work. Laboratory members are collectively engaged in working out a conceptual framework for cognitive research based on activity theory. Beach and Stevens, together with Scribner, elaborated this framework in the domain of memory, and in this introduction we will briefly sketch its principal implications for the ecological study of memory.
ECOLOGICAL APPROACHES TO MEMORYOver the past decade ecological investigations of memory have come to play an increasingly important role in memory research. Today it is difficult to find a psychologist who, on some level, does not acknowledge the importance for psychology of locating and describing memory phenomena in everyday life. We are hard-pressed, however, to find agreement on the particular contributions such research is expected to make to our understanding of memory processes. An article by Bruce (1985a), responses by Neisser (1985 and Hirst and Levine (1985), and a reply by Bruce (1985b) illustrate the principal lines of disagreement. A more recent series of articles initiated by Banaji and Crowder (1989) and responded to by Loftus (Bruce (1991) continue the debate.As we see it, three methodological approaches can be distinguished. Some psychologists (Crowder, 1976;Nakamura, Graesser, Zimmerman, and Riha, 1985) are interested in ecological research as a way of validating principles of memory obtained in laboratory studies. This approach assigns special status to the laboratory as a 'privileged' site for memory research, but reflects a concern to test the validity of
