Robotic Exposure Affects Human's Ability to Empathise With Them
The researchers believe that brain regions thought to be responsible for our ability to relate to each other might be behind the ability to sympathise.
In humans and monkeys, the mirror neuron system (MNS) - a collection of neurons in various parts of the brain, including the premotor cortex and the primary motor cortex - fires both when you perform an action and when you watch someone else perform a similar action.
They have found that MNS plays a key role in creating empathy.
It allows people to transform the actions that they see others performing into internal representations.
Many researchers have tried to see if the MNS is activated when humans observe robots.
However the results have been inconclusive, with some experiments suggesting that the MNS reacts to robots and others concluding the opposite.
"This difference may be due to [differences in] the robot stimuli used in the experiments," New Scientist quoted Sotaro Shimada of Meiji University in Tokyo, Japan as saying.
During the study, researchers decided to test separately the effects on the MNS of the appearance of robots and the way they moved (their kinematics).
They recruited twelve adults, aged 23. They were asked to watch computer-generated videos of either a humanoid robot or a person reaching out with their right hand to grasp an object.
