International audience The "cognitive revolution" has greatly modified the links between scientific disciplines and the related theories and models proposed to explain behaviours. The relation between emotion, language and decision-making, taken into account in the present paper, shows such a revolution. Indeed, beside the obvious intrinsic interest of a better understanding of these psychological states and their impact on behaviour, their study as interdependent entities illustrates, in many ways, the need of new strategies of analysis that consider the holistic nature of the human behaviour. After briefly reminding some fundamental conceptual benchmarks, this paper attempts to present the traditional views of philosophy, psychology and the premises of the neuropsychology of language on these issues. Then, it continues showing how cognitive neuroscience has immediately considered these references as closely linked in a cognitive network. With respect to this global view, we need to rethink methodologies, in order to reach a better account of the holistic, dynamic and progressive aspects of these behaviours by using the concepts of network and "constructs".
