A partial replication of Thelin et al. s Usage Based Reading experiment

In this paper, we partially replicate Thelin et al. s investigation of usage based reading (UBR). Our study design is very similar to Thelin et al. s., except we were unable compare the use of UBR with a second reading technique. Instead, seven subjects used UBR to inspect the same design document as used in Thelin et al. s study, under the same experimental conditions. We ask the general research question: How does the performance of the subjects--in our study, using UBR, compare with the performance of those subjects using UBR in Thelin et al. s study We find that the subjects in our study perform slightly better than the comparable subjects in Thelin et al. s study. There is some indication of better performing and poorer performing subjects. There is also some indication of easier and more difficult--faults to detect.
