Abstract: Awareness tools using visualized ratings of other people can help recipients to find their way in crowded information spaces. This article reports on a laboratory experiment that investigates how the design of an awareness tool impacts the navigation behavior of recipients within an online discussion forum. In the experiment, 127 participants read through a forum discussion for which posts were rated by average agreement and average quality. Depending on the experimental condition, posts were visualized along continua indicating average agreement ratings (absent vs. present) and/or average quality ratings (absent vs. present). It was hypothesized that an agreement visualization will increase the salience of both high- agreement and low-agreement posts, whereas a quality visualization will only increase the salience of high-quality posts. Measuring reading times for discussion posts, these hypotheses could be confirmed. However, neither recipients' attitude strength nor recall of discussion arguments was affected.
