This volume attempts an ontogenetically oriented understanding of the behavioral development of free-living infant chimpanzees. The focus of the investigation is on the organization underlying developing behavior. The study serves as a model for achieving an integrated view about early development and motor behaviors from separate cases. The monograph is beautifully illustrated to depict postural and other behavioral expressions studied.
