The Social Psychology of Human-agent Interaction

Abstract

Designers of human-agent systems often assume that users interact with machines as if they are interacting with another person. As a consequences, fidelity to human behavior is often viewed as the gold standard for judging agent design, and theories of human social psychology are often accepted without question as a framework for informing human-agent interaction. This assumption was given strength by the pioneering work of Cliff Nass showing that many of the effects studied within social psychology seem to apply to human-machine interaction. In this talk, I will illustrate that these social effects are much weaker than widely supposed, and that the differences in how people treat machines are arguably more interesting than the similarities. These differences can lead to novel insights into human social cognition and unique technological solutions to intractable social problems. I will discuss this in the context of our research on education and mental health. Thus, rather copying human behavior, I will argue that HAI researchers should aim to transcend conventional forms of social interaction, and work towards novel theoretical frameworks that address the novel psychology of human-agent interaction.
