Abstract
Cognitive science, is the science of the mind and examines cognition, in all its scope, as a mental-brain process. Cognitive social sciences are resulted from the encounter, interaction and integration of social and cognitive sciences, and are hoped to deepen our understandings and explanations of the social phenomena. This paper will discuss four views about what this integration is and how it takes place, namely explanatory grounding, theoretical unification, constraints, and complementarity. some people have preferred explanatory grounding and constraints approach, and maintain that based on these approaches, social cognitive science will have a better and a clearer perspective. In spite of them, I prefer a complementarity approach, Based on which, cognitive social science can be seen as an extension and improvement of social science and cognitive science, not a product of an interdisciplinary approach, This preferred approach considers the subject of cognitive social science as a socio-cognitive issue.
