Abstract

Examines some of the theories that have evolved to explain the mental processes required for the use of information systems. Categorizes research in this area into system oriented and user oriented studies and reviews this research. Describes a sample of methodologies used for examining users and their information seeking behaviour. Concludes with a discussion of the implications of these theories and methods for librarians and information specialists

Abstract

This study sought to investigate the effects of cognitive style (field dependent and field independent) and on-line database search experience (novice and experienced) on the WWW search performance of undergraduate college students (n=48). It also attempted to find user factors that could be used to predict search efficiency. search performance, the dependent variable was defined in 2 ways: (1) time required for retrieving a relevant information item, and (2) the number of nodes traversed for retrieving a relevant information item. the search tasks required were carried out on a University Web site, and included a factual task and a topical search task of interest to the participant. Results indicated that while cognitive style (FD/FI) significantly influenced the search performance of novice searchers, the influence was greatly reduced in those searchers who had on-line database search experience. Based on the findings, suggestions for possible changes to the design of the current Web interface and to user training programs are provided
