The challenge prompted a team of Osaka University-centered researchers to delve deeper into the topic.

First, they recorded movies of Geminoid F, an android developed by Osaka University and Advanced Telecommunications Research Institute International, and its actual human model. This allowed the researchers to investigate what differences a slight degree of motion unnaturalness would make to feelings about the android.

Second, they used functional magnetic resonance imaging (MRI) to investigate what brain region activates when participants observed the android's and the human's movements in the movies, wherein they were only slightly different in naturalness. The subthalamic nucleus is found to be responsible for detecting the android's slight awkwardness.

"Visual observation of the android, compared with that of the human model, caused greater activation in the subthalamic nucleus (STN), which plays an...
