Effect of relationship experience on trust recovery following a breach

Significance Will people be more likely to forgive a breach of trust in an earlier or later stage of an interpersonal relationship? The present article reports behavioral and neurophysiological experiments that speak to this important question. Results show that trust recovery is facilitated with increasing relationship experience. Differential activation in the controlled social cognition system (C-system) and the automatic social cognition system (X-system) indicate that decision making is less controlled and more automatic following a later as opposed to an earlier trust breach. These findings have important implications for the study of trust recovery after a breach, as well as the neuroscience of trust. A violation of trust can have quite different consequences, depending on the nature of the relationship in which the trust breach occurs. In this article, we identify a key relationship characteristic that affects trust recovery: the extent of relationship experience before the trust breach. Across two experiments, this investigation establishes the behavioral effect that greater relationship experience before a trust breach fosters trust recovery. A neuroimaging experiment provides initial evidence that this behavioral effect is possible because of differential activation of two brain systems: while decision making after early trust breaches engages structures of a controlled social cognition system (C-system), specifically the anterior cingulate cortex and lateral frontal cortex, decision making after later trust breaches engages structures of an automatic social cognition system (X-system), specifically the lateral temporal cortex. The present findings make contributions to both social psychological theory and the neurophysiology of trust.
