In a research study done by University of California San Diego, human brain reaction to the humanoid robots’ human appearance vs. their human-like movements have been examined. The study was led by Ayse Pinar Saygin, an assistant professor of cognitive science at UC San Diego and alumna of the same department.  According to Saygin, the brain is not necessarily looking for biological movement however when it sees a biological looking robot behaving differently, that is where it is confused, as the expectation is not met in that case. The research team used 20 subjects, between ages 20 to 36, who had not spent time with robots before. For more detail information about the study, please visit the official site here
