A Socially-Aware Memory for Companion Agents
Abstract. Memory is a vital capability for intelligent social Companions. In this paper, we introduce a simple memory model that allows a Companion to maintain a long-term relationship with the user by remembering past experiences in order to personalise interaction. Additionally, we implemented a situational forgetting mechanism that gives the Companion the ability to protect the user’s privacy by not disclosing sensitive data. Two test scenarios are used to demonstrate these abilities in our Companions.

Are preventive and generative causal reasoning symmetrical? Extinction and competition
We tested whether preventive and generative reasoning processes are symmetrical by keeping the training and testing of preventive (inhibitory) and generative (excitatory) causal cues as similar as possible. In Experiment 1, we extinguished excitors and inhibitors in a blocking design, in which each extinguished cause was presented in compound with a novel cause, with the same outcome occurring following the compound and following the novel cause alone. With this novel extinction procedure, the inhibitory cues seemed more likely to lose their properties than the excitatory cues. In Experiment 2, we investigated blocking of excitatory and inhibitory causes and found similar blocking effects. Taken together, these results suggest that acquisition of excitation and inhibition is similar, but that inhibition is more liable to extinguish with our extinction procedure. In addition, we used a variable outcome, and this enabled us to test the predictions of an inferential reasoning account about what happens when the outcome level is at its minimum or maximum (De Houwer, Beckers, & Glautier, 2002). We discuss the predictions of this inferential account, Rescorla and Wagner’s (1972) model, and a connectionist model—the auto-associator.Irina Baetu & A. G. Bake
