Towards a multi-motivational model of human nature SUMMARY. The Attachment theory not only highlights developmental issues and clinical phenomena, such as the formation of attachment ties, separation anxiety and loss, which are evaluated through new perspectives; it also generated a research program that has confirmed fundamental premises of the theory as well as enriched and expanded the theory with new empirical findings. This essay is organized in four parts, the third and the fourth will be published in the next issue (24/2007). In the first part the authors lay out the basic structure of the Attachment theory and compare it with other motivational systems. In the second part they propose a multi-motivational model of human nature proposing a taxonomy of human motivation in an evolutionary perspective. In order to develop a comprehensive view of human motivation, the essay answers two key questions: 1) What are the characteristics of our species that make us unique? 2) How do these emerging properties modify the foundation of the motivational systems that connect us to other mammals and primates?
