We will study factors that potentially influence the strength of the renewal effect of extinction: i.e. external (context-related) and internal (structural and process-related) potential moderators of renewal. By manipulating the saliency and generalizability of contexts, we aim to alter context processing and thus the level of renewal. By means of pharmacological intervention, we will modulate initial learning of associations to investigate potential effects upon renewal. Using various neuroimaging methods, we will relate task-associated activation in extinction-relevant brain regions, functional and structural connectivity as well as structural brain features to the propensity of showing renewal.
Guiding questions of A08:
Our proposed studies will extend the present knowledge about the mechanisms of the context-related recovery of extinguished responses and thus can provide new insights for therapeutic interventions.
