The dynamics of creative processes offers a theoretical foundation for
psychodynamics, and practical methods for research and clinical pract
ice. Psychological phenomena are complex sequences of physical action
(action = energy x time). The same simple processes repeat at every le
vel of organization: (0) spontaneous fluctuations; (1) temporal flow;
(2) oppositions (harmonic, conflictual and creative) but not equilibri
um; (3) co-creations of tridimensional structure, and of higher dimens
ional organization. Simpler processes have priority, but complex organ
ization acquires supremacy (as contrasted to both biological reduction
ism and psychological autonomy). Operationalizing these principles, th
e process method studies processes as time series, analyzes change in
terms of opposites (harmony/conflict, attraction/repulsion) using a co
ordinate plane, and measures organization by quantifying recurrences a
nd entropy in multidimensional frameworks. The process method is illus
trated by longitudinal recordings of mood (psychogeometry), of interpe
rsonal relations (sociodynamic tests), and of heart rate patterns asso
ciated with emotions. These studies reveal novelty-rich multidimension
al patterns (complexes), instead of the stable low-dimensional attract
ors of deterministic dynamics, or the random distributions of probabil
istic models. Conceptualizing psychological processes as complex and c
reative physiological actions suggests a new approach to clinical diag
nosis and treatment.
