This paper is the first in a series of articles on human development. The outline for a communicative psychoanalytic theory of human development is presented in: one postulate, four theorems, one lemma, and one corollary derived from the clinical and theoretical works of Robert Langs, and in: six theorems, three lemmas, and two corollaries developed out of the authorís naturalistic observations of the growing human from birth on. Principal theorems include statements that veridical unconscious perception of interactions with others is the inborn capacity of human mind, and that these unconscious perceptions of intent and actions of others, rather than elaborations or distortions, are basic determinants of human development from birth on. Communicative methodological concepts for the empirical basis for this theory are presented. A modification of the communicative methodological data requirement for use with non-verbal interactions is briefly described. Nine issues in human development that are deemed to be important and interrelated are listed as sources of topics for planned papers under the same umbrella-title.
