Pictures are non-linguistic external representations; as such, they can exploit the fineness of grain that normally comes with perceptual acquaintance, as opposed to verbal description. But how does this distinctive trait of pictures translate into a form of meaning? What is the role of concepts and depth-perception in understanding pictures? What is the semantic status of perceiving images while having the multimodal experience of films or virtual simulations? (Topic I) Beyond such questions, how do we make use of pictures? The conference will concentrate on the use of pictures in science, be they drawings, diagrams or photographs. Pictures are genuine vehicles of scientific content, but the reasons why they play such an indispensable role are poorly understood. Sometimes, pictures are data. Does this mean that the observation of pictures has the same epistemic value as the observation of natural scenes? Can pictures be more than cognitive facilitators in scientific contexts? Can they be parts of arguments, or are arguments strictly linguistic? How can they depict (parts of) theoretical models? interdisciplines.org
