The aim of the present work was to investigate differences in the perception of robotic (point-to-point) and humanlike (anthropomorphic) movements in men and women (biological sex). Two virtual models were used for this purpose, a virtual robot and a digital human model. Simulated videos of these models showed robotic and anthropomorphic placing movements. The subjects were asked to rate on a Likert scale the perceived levels of human likeness or robot likeness in the two models. During this process, the subjects were lying in a magnetic resonance imaging scanner. The behavioral results suggest that male participants perceived the differences between robotic and anthropomorphic movements, while females showed no differences between them, whereas female participants attributed more anthropomorphic features to the robotic movements than the males. In the fMRI study, we analyzed brain activations of males and females while observing the robotic and anthropomorphic movements of the two models. The results show that observation of the human model as well as observation of the anthropomorphic movements equally activated the biological motion coding areas in the posterior temporal and parietal areas. Whereas observation of the robot model predominantly activated areas of the ventral stream, observation of the robot movements activated the primary and higher motor areas (dorso-dorsal stream). These activations were particularly present in females, whereas the males activated the posterior parietal cortex during both the robot model and the robotic movements (ventro-dorsal stream). In summary, males tend to use the ventro-dorsal stream to employ existing prior knowledge to analyze movements, whereas females use the dorso-dorsal and ventral stream to analyze the differences between movement types as well as models. This study is a first step toward understanding the influence of biological sex on the processing of robotic and anthropomorphic movements. This knowledge will help in the implementation of robots in everyday (work) environments.
