The subsystem relations of Decision Making and Conation are the topic of this contribution, because they are in the deep shadow of research interests devoted to relations of Decision - Cognition and Decision - Emotions and are even less investigated than Decision - Motivation relations, too. The selected structural aspects of relations of Decision and Conation are analysed.
Than the exploration shifts to procesual aspects of Decision and Conation interactions in a Pre-decisional phase, a phase of Proper Decision and a phase of Implementation of fully developed Decision. An investigation of a causal, an instrumental and teleological (intentional) aspects of a whole process of Volitional and Decisional reciprocal determinations are included, too.
