Abstract
Prominent stage theories of cognitive development show evidence of a structure in which each stage contains a number of subsidiary levels. Comparisons of the stages in these theories have commonly been made through the established links with stages of Piaget's theory. In response to Kagan's criticism of Piaget's theory, features of these developmental theories were used in this paper as the basis for a general framework of interactive stages and levels of cognitive operations. Some implications of the proposed framework in relation to cognitive development theories and directions for further research are examined. Further application of this framework could help to identify commonalities in cognitive operations across different contents, contexts and cultures.
