Dreaming Your Fear Away: A Computational Model for Fear Extinction Learning during Dreaming

摘要

In this paper a computational model is presented that models how dreaming is used to learn fear extinction. The approach addresses dreaming as internal simulation incorporating memory elements in the form of sensory representations and their associated fear. During dream episodes regulation of fear takes place, which is strengthened by Hebbian learning. The model was evaluated by a number of simulation experiments for different scenarios.
