This study investigated the effect of familiarity and concreteness of task-descriptions on the process of understanding computer programs. In a 2x3x2-factorial design 18 experts and 18 novices could inspect simple programs by means of a subject-paced-reading technique. The programs either solved a common task in a familiar or in an unfamiliar manner or solved another task. After inspecting the code the subjects had to decide wether the task was handeled by the code. Experts needed significantly less time than novices to inspect the task descriptions. In the analysis of the programs novices performed better after concrete task descriptions than after abstract task descriptions. Overall, experts gave more correct decisions than novices, although both groups showed similiar patterns with regard to the familiarity of the tasks. The main result was that experts performed faster and reached a higher level of correct decisions. The results point at domain-specific skills as a cornerstone of expertise.
