@inproceedings { gomes11, abstract = {In the present article a model for memory retrieval of personal experiences for virtual agents is presented. It builds upon previous work and focuses on the effect memory retrieval can have on the agent's emotional state. Memory retrieval is defined as an emotional re-appraisal of past experiences. The variation of intensity of such re-experience is explored by modeling two phenomena: downward spirals and habituation. Downward spirals consist of situations in which recurrent retrieval of negatively charged past memories increases the recall intensity of such memories in depressed individuals. Habituation is the reduction of recall intensity caused by re-experiencing past experiences in a context perceived by the individual as safe.}, address = {York, UK}, booktitle = {Proc. of The 2nd Symposium on Human Memory for Artificial Agents in AISB’11}, month = {April}, pages = {15-19}, publisher = {Society for the Study of Artificial Intelligence and the Simulation of Behaviour (AISB)}, title = {Between Downward Spirals and Habituation: Emotion Intensity in Virtual Agents' Memory Retrieval}, year = {2011}, author = {Paulo F.
