How events affect trust: A baseline information processing model with three extensions

Abstract

This article addresses how trust changes over time. We introduce a social psychology-based Information Processing Model (IPM) that explains how trust changes over time based on three cognitive mechanisms: attention, attribution, and judgment. This model is contrasted with the traditional incremental progression model of trust change. We also explain three extensions of the model. These models are then simulated and the results suggest that incremental progression may be inconsistent with established psychological theory. © 2012 IFIP International Federation for Information Processing.
