Research output: Contribution to journalArticlepeer-review


To operate a computer software system computer users need to obtain information about the system at five levels of abstraction, from concrete to abstract: physical, logical, functional, conceptual, and objective. The five levels of information may be presented at different stages of users' training, with each stage involving only a certain kind of information. An experiment was conducted to investigate the effects of physical + logical information versus functional + conceptual information given at different stages on users' performance. Subjects with no prior knowledge of a computer database received two stages of training to learn how to construct queries of the computer database. At the preliminary stage, only one kind of information was provided. After two stages, the subjects were asked to perform query tasks using the database. The statistical analysis of subjects' accuracy showed no significant effects of information at either stage and no significant interaction. Explanations of this finding are provided.
