Expectancy-value beliefs and information needs as motivators for task-based information seeking

Purpose - The purpose of this article is to elaborate the picture of the motivators for information seeking by comparing the conceptualizations of task-based information needs and expectancy-value theories. Design/methodology/approach - The article is a conceptual analysis of major articles characterising task-based information needs and expectancy-value theories developed in psychology since the 1950s. Findings - The conceptualizations of task-based information needs approach the motivators for information seeking in terms of the informational requirements posed by tasks at hand. However, the ways in which such needs trigger and drive information seeking have not been specified in detail. Expectancy-value theories provide a more elaborate picture of motivational factors by focusing on actors' beliefs about the probability of success in information seeking and the perceived value of the outcome of this activity. Research limitations/implications - The findings are based on the comparison of two research approaches only. Originality/value - So far, information scientists have largely ignored the psychological theories of motivation. This study demonstrates the potential of such approaches by discussing an established psychological theory. The findings indicate that such theories hold a good potential to elaborate the models of task-based information seeking in particular.
