Accounting for the human in cyberspace: Effects of mood on trust in automation

The present study examined the effects of mood on trust in automation over time. Participants (N = 72) were induced into either a positive or negative mood and then completed a computer-based task that involved the assistance of an automated aid. Results indicated that mood had a significant impact on initial trust formation, but this impact diminishes as time and interaction with the automated aid increases. Implications regarding trust propensity and trustworthiness are discussed, as well as the dynamic effects of trust over time.
