The introductory course to sociology serves the multiple roles of providing students with the foundations of the field while also being its "public face" and possibly improving its image. The outcomes of introductory courses have been investigated mostly in quantitative ways in the past. The article presents a qualitative, longitudinal study of the "mental image" that 397 students of an introductory course at a Hungarian university formed about sociology. Participants were asked to draw mind maps around the central concept of "sociology" right before, right after, and years after taking the course. Results from the content analysis of mind maps indicate that while students are able to situate sociology as a science of the human world, their mental image of the field is often vague beyond that. Mind maps drawn years after taking the course bear the closest resemblance to the ones drawn even before studying it.
