To examine the transfer of knowledge representation between task domains, working engineers and pharmacists were asked to provide pairwise dissimilarity ratings of concepts in a test domain. The test domain was independent of engineering and pharmacy and was relatively new to both subject groups. A quantitative technique based on the multidimensional scaling and directional statistics was used to test and evaluate group differences in knowledge representation. The results indicated that there was no statistically significant difference between two groups in knowledge representation of the test domain. That is, knowledge representation was domain-specific and was not transferable between task domains.
