Possibly the earliest reference is the following, although it does not use the exact term "macrocognition": A macro-theory is a theory which is concerned with the obvious regularities of human experience, rather than with some theoretically defined unit.
However, the idea of a macro-theory does not entail an analysis of the mechanistic materialistic kind which is predominant in cognitive psychology.
To take another example, we should have a macro-theory of attending, rather than a mini-theory of attention, or micro-theories of limited channel capacities or logarithmic dependencies in disjunctive reaction times.
... To conclude, if the psychological study of cognition shall have a future that is not a continued description of human information processing, its theories must be at what we have called the macro-level.
Macrocognition is distinguished from microcognition by elements of time-pressure and risk, performance by experts (as opposed to college students or novices), ambiguity of goals and outcomes, and complex and unclear conditions.
