Abstract

Considers 4 approaches that have been idetified for studying information needs: cognitive; social; social cognition; and organizational; using a problem solving model. Identifies individual and situational variables that influence how individuals and groups experience information needs and shows how research into the information needs of users and the design of user centred information systems and services can be guided by an integrated understanding of how individual and situational variables affect normal behaviour

Abstract

Tests the logical reasoning ability of end users of a CD-ROM index and assesses associations between different levels of this ability and aspects of retrieval performance. Users' selection of vocabulary and their selection of citations for further examination are both influenced by this ability. The designs of information systems should address the effects of logical reasoning on search behaviour. People with lower levels of logical reasoning ability may experience difficulty using systems in which user selectivity plays an important role. Other systems, such as those with ranked output, may decrease the need for users to make selections and would be easier to use for people with lower levels of logical reasoning ability
