Traditions in the cognitive psychology of science

By "tradition", we mean here a set of ideas sharing certain common assumptions about the way in which cognitive considerations ought to motivate research on scientific thinking. In most cases, these traditions are not closely linked by a common heritage in the sense they are grouped within particular institutions, nor are they reflective of "teacher-student" descent in very many cases. As historical descriptive categories, then, the distinctions made would not survive careful historiographic scrutiny. None the less they do focus our attention upon certain presuppositions and certain commonalities ofcited works; each tradition is an invisible college.
