This paper describes an experiment in reading graphic data models which differ in graphic style. Computer science students participated in an experiment to determine if graphic style influences data model comprehension. Models with embedded graphic symbols, graphically separated symbols, or list structures were used. Protocol data, which consisted of verbal reports and eye-movements, was collected. Detailed analysis of this data provided insight into how students viewed the four types of data models. Results from this study suggest that the graphic style of the model effects the ease with which they are read and understood.
