Experimental Evidence of the Knowledge Gap: Message Arousal, Motivation, and Time Delay

Human Communication Research, v34 n4 p550-571 Oct 2008
This study experimentally tested the knowledge gap from an information processing perspective. Specifically, knowledge acquisition was investigated under conditions of medium and low news message arousal, with time delay. Results show the persistence of a knowledge gap, particularly for low arousing messages. In fact, at low levels of message arousal, the gap is larger than at medium levels of arousal. Some existing research suggests that message salience explains the knowledge gap. Findings from this study show that information processing aptitude may also be a significant factor. Measures of several dimensions of participant motivation to cognitively engage with news messages were added as covariates to statistical analyses. These were found not to affect the knowledge gap outcomes in this data set.
