Information practices and cognitive artifacts In scientific researcn

摘要

A cognitive ethnography study investigates information practices in experimental life sciences research. Activity analysis of collaborative research projects and cognitive artifacts revealed a series of seven cognitive information tasks performed in the lifecycle of the research project. Life scientists exhibited habituated patterns of search behavior in the institutional information ecology. Scientists have widely adopted the transparent search interfaces of PubMed and Google, rarely employing full text or specialized services for searching publications. An activity theory approach suggests explanations for interface and information use. Individual researchers in the research project context perform information tasks to locate information objects, mediated by the printed article as a primary cognitive artifact. A cycle of use shows that interface transparency mediates the pursuit of information objects through locating "opaque" cognitive artifacts. Such simple, transparent information tasks become routinized operations. Individual attention becomes focused on the artifact and information object, not the user interface.
