The perception of information relevance

Abstract

The effect of experimentally induced information relevance on Ss’ perception of information relevance and information importance in complex environments was investigated. Ss received 10 informative messages in each of four Y2-h periods. Twenty per cent, 40%, 60%, or 80% of that information was relevant (permitted meaningful responding). A constant 80% of all information was important. Ss’ perceptions of information relevance and importance were obtained on rating scales. It was found that experimentally induced increasing relevance resulted in increasing perceptions of relevance and importance; however, perceptions of relevance and importance were higher than induced relevance at all but the 80% point. © 1970, Psychonomic Journals, Inc..
