She explains: “In general, we expect that when the robot is more active and takes more turns, it will be perceived as more extroverted and socially engaging. This is true up to a point. When it’s extremely active, the robot actually acts very egocentric, like it does not care at all that the partner is there, and is less engaging. It actually makes sense; it is sort of like interacting with someone who is self-centered and talks about herself all the time. This is why a balance of being active or passive is really needed.”
