Brain network evaluates robot likeability

Researchers have identified a network of brain regions that work together to determine if a robot is a worthy social partner, according to a new study published in JNeurosci.

Using functional magnetic resonance imaging, Astrid Rosenthal-von der Pütten, Fabien Grabenhorst and colleagues evaluated brain activity from the prefrontal cortex and amygdala as human participants scored images of robots on their likability, familiarly, and human-likeness. The participants also chose the robot from which they would prefer to receive a gift, indicating their social value.
