Abstract
The medicine is a social object that is at the heart of many material and symbolic relationships. In order to know the opinions and knowledge associated with it within the French population, we mobilized the theoretical framework of social representations. Due to the massive spread of images in new mediums of communication, we chose to limit the research that constitutes this PhD in the iconographic perspective. As such, our investigations revolve around two axes: The first axis (N = 946) is concerned with the involvement of the mental imagery in the formation of social representation of the medicine. The three investigations carried out with this focus allowed us to observe the collective nature of mental imagery, encouraging research on the images. The second axis (N = 615) focuses in the processes mobilized by individuals when it comes to selecting, memorizing and understanding the images associated with the prototypical words of the social representation of the medicine. The results suggest the development of a methodology with the images. As a whole, the investigations invite the reader on one hand, to consider the importance of social representations in the deciphering of visual images, on the other hand to dig deeper in the iconography of the methodological perspective of the theory of social representations.
