Proposal for the model of occurrence of negative response toward humanlike agent based on brain function by qualitative reasoning

Abstract

For designing the rounded communication between human and agent, humanlike appearance of agent can contribute to human understandability towards their intension. However, the excessive humanlike-ness can cause human to feel repulsive against the agent, which is well known as the uncanny valley. In this study, we propose a model providing an explanation for how the human negative response is fomred, based on the brain regions and its function, including the amygdala, hippocampus, cortex and striatum. This model is described with quantitative reasoning and simulated. The results indicate that as human observes a humanlike agent, the emotion goes negative and the brain regions were more activated in comparison with the case human observes a person. © 2014 Springer International Publishing.
